What's new in release 3.17.0?
Firmware release 3.17.0 is packed with new features for VGADVI Recorder Pro. Features include support for
IP cameras as sources, dynamic overlay text in custom layouts, portable configuration presets, control for
streaming and a brand new control interface – Epiphan Live!
New features include:
IP cameras
Firmware 3.17.0 now offers support for IP cameras as sources. Easily connect any RTSP-based camera and
start capturing over a network!
Epiphan Live
Epiphan Live is a new, intuitive and easy-to-use interface for controlling and monitoring streaming, recording
and live switching using a PC, laptop or tablet.
Dynamic text
Users can now create new system-wide variables via HTTP API, insert them into their custom layouts as
overlay text and update variables with a script for dynamic layout overlay text!
Refined streaming control
Precisely control streaming with ease using convenient start/stop streaming buttons in the Admin panel.
Portable configuration presets
Save system settings into portable configuration presets for backup and/or easy transfer of configuration
settings to additional VGA Grid and VGADVI Recorder Pro systems.
Progressive MP4 and improved support for Adobe Premiere Pro
Choose to save recordings as progressive MP4 files for improved post-processing support using tools such as
Adobe Premiere Pro. (Note that Adobe Premiere Pro does not support variable frame rate files, so small audio
offsets are still possible when using it for post processing.)
Resolved issues
The following issues were resolved in 3.16.1e:
l Fixed an issue where minor signal noise was detected when capturing from HDMI sources. Discovered
through our ongoing, automated frame-by-frame testing, but not perceptible to the human eye, some
frames captured from HDMI sources had an undesirable flicker that is resolved in this release.

VGADVI Recorder Pro Overview
VGADVI Recorder Pro Overview
VGADVI Recorder Pro is a professional audio/video streaming system that captures, synchronizes and records
up to four HD video sources, two SD video sources and up to three audio sources. Epiphan’s VGADVI
Recorder Pro captures video signals at resolutions up to 2048×2048 (DL model) with rates of up to 80 frames
per second.
This versatile system has a variety of options enabling you to create and configure any number of streaming
channels. You can choose to stream (or record) a single channel at once or a configuration of synchronized
channels with picture-in-picture or picture-with-picture multiplexing selections.
AV inputs
The latest hardware revision of VGADVI Recorder Pro supports the following AV inputs directly. Nearly every
other AV input is supported provided you have the correct converter or adapter.

VGADVI Recorder Pro User Guide
What's in the box?
Latest hardware revision:
VGADVI Recorder Pro can now capture more HD content than ever before. The newest VGADVI Recorder Pro
comes with four HD inputs. Half the inputs are for capturing from DVI/HDMI/VGA sources while the other
half are for SDI sources. As before there are also two S-Video ports.
With this combination of available input ports and applicable DVI, SDI or S-Video adapters/converters you can
bring in signals from nearly any source. This hardware upgrade also provides audio capture support for HDMI
and SDI in addition to pre-existing support for 3.5 mm analog audio input ports.
Previous hardware revisions
Previous versions of VGADVI Recorder Pro came with two HD inputs. Many, although not all, previous
rackmount hardware revisions can support the latest software release. Compact versions do not support the
firmware upgrade due to hardware limitations. Use the Firmware upgrade feature to see if your device is
upgradeable. Note previous hardware revisions do not support HDMI audio capture.
Unpacking the box
The following list applies only to new devices with the latest hardware revision:
1. Two VGA to DVI-I cables (3 feet / 1 meter in length
each)
2. Two HDMI to DVI-I adapters
3. Two DVI-I cables (3 feet / 1 meter in length)
4. Two composite to S-Video cables
5. Two SDI cables (3 feet / 1 meter in length)

VGADVI Recorder Pro User Guide
Quick Start
Quick Start
This section helps you get up and running quickly with your VGADVI Recorder Pro.
l Step 1: Physical set-up and power-on
l Step 2: Admin discovery and login
l Step 3: Set up the video source
l Step 4: Configure the channel
l Step 5: Testing the stream
l Step 6: Recording the stream
Before you get started, make sure you have:
l an HD source (i.e. a computer, a tablet, or a phone)
l the appropriate cables or adapters to convert the output to DVI or SDI (if needed)
l ideally, a network with Dynamic Host Configuration Protocol (DHCP)
l a computer with a web browser connected to the same network (this is referred to as the “admin”
computer in the steps below)
l optionally, an audio source such as a microphone or the headphone jack from a laptop . Note that
audio signals sent over HDMI and SDI are supported in the latest hardware revision(s). If you have
SDI ports, your system supports HDMI and SDI audio.
These instructions include steps for setting up and configuring audio. Skip these optional steps if
you do not want to configure an audio source at this time.
Step 1: Physical set-up and power-on
Complete the following steps to prepare and power on the system. Refer to the Front and Back Panel View
section for your system to locate the appropriate input ports.
1. Turn on your HD source and connect the output cable to a DVI-I or SDI port on the back of the system.
2. (optional) Attach a 3.5 mm audio cable from your audio source to the system’s motherboard audio
input port(blue port on the back of the system).
3. Connect the Ethernet cable to the VGADVI Recorder Pro.
4. Connect the Ethernet cable to your network.
5. Attach the power cable to the system and plug it into a power source.
19
VGADVI Recorder Pro User Guide
Step 2: Admin discovery and login
6. Unlock the front panel and press the power button to turn on the system.
7. Wait for the VGADVI Recorder Pro to complete the power up sequence. The power LED illuminates and
the hard drive LED flashes during start up.
Step 2: Admin discovery and login
The VGADVI Recorder Pro is managed from an Admin panel. This interface acts as a configuration utility and
system monitor. The first time you access the Admin panel you will not know the IP address of the system.
The steps below use DNS-based service discovery (a type of zero-configuration networking) to access the
system. Depending on the operating system on your admin computer you may need to install some software
before you can used DNS-based discovery.
This quick start is meant for systems that support DHCP and DNS, however if your system does
not support these mechanisms, refer to Connect to the Admin panel and Connect to the
Admin panel for alternative discovery mechanisms. Return to step 3 below when you have
completed setting a static IP address for the VGADVI Recorder Pro.
Table 6 Installing Bonjour Print Services
System
Action Needed
You must install Bonjour Print Services:
1. Use the following URL - http://support.apple.com/kb/DL999
Microsoft Windows
2. Click Download.
3. Follow the system prompts to download and install the application.
Mac OS X
The Bonjour software used for service discovery is built in to the Mac OS. No special
actions are needed.
The Avahi implementation used for DNS-based discovery is shipped with most Linux
Linux
distributions. If necessary, check with your administrator to ensure you have the
Avahi package installed.
You are able to access the system Admin panel on the local network by specifying its serial number in a web
browser on your admin computer.
1. Find the system’s serial number. It is printed on a sticker on the back of the unit.
2. Type the following string into the address bar of your web browser on your admin computer (where
<serial> is the serial number of your VGADVI Recorder Pro):
20
VGADVI Recorder Pro User Guide
Step 3: Set up the video source
http://<serial>.local/admin
For example: http://95dd40d5.local/admin
3. Enter the user name and password then click OK. The administrative user is ‘admin’. Initially no
password is set. To set a password follow the procedure outlined in User administration.
4. Optionally, navigate to the Network link under the Configuration heading and note the IP address of
the system.
Step 3: Set up the video source
The Admin panel has a pre-configured list of the frame grabbers in the Sources section. Each video input card
on the back of the system is a frame grabber. Each frame grabber has one DVI port, one SDI port, one S-Video
port and one 3.5 mm audio port. The sources are listed by their frame grabber serial number.
DVI ports are listed with the suffix .vga, SDI ports are listed with the suffix .sdi, S-Video inputs listed with the
suffix .video, and analog audio inputs are listed with the suffix _analog or, for the audio port on the
motherboard: Analog. Digital audio inputs (for systems with SDI ports) are listed with the suffix .hdmi-audio
or .sdi-audio, depending on their source.
The serial numbers for your system will not be the same as the examples shown below.
1. From the Admin panel, scroll to the Sources section. (You will see more sources than shown below.)
21
VGADVI Recorder Pro User Guide
Step 3: Set up the video source
2. Find the DVI (or SDI) source that you have connected by selecting each DVI (or SDI) source (named .vga
or .sdi as the suffix) and verifying if the preview on the right side of the screen reflects your source
material.
3. Make note of the name of the source, or optionally, change the source name to reflect the data it is
capturing.
To rename the input source:
a. Click on the source name at the top of the source configuration window. The name text
becomes red.
b. Edit the name. The following characters are supported: a-z; A-Z; 0-9; + (plus); - (hyphen); _
(underscore); , (comma), . (period); ~ (tilde); # (hash); [ ]; ( ). Although spaces are also supported,
it is suggested you use underscores to separate words.
c. Press Enter on the keyboard. The name is updated at the top of the screen and in the list of
sources at the left side.
4. Optionally, configure the audio source (if connected):
a. Scroll to the Sources section again and select the motherboard audio source. It is prefixed by
the word audio and suffixed Analog (i.e. audio ALC892 Analog). The audio configuration page
appears.
b. From the Input source drop-down list, select Line for the blue port at the back of the system.
c. Click Apply.
Source setup is complete. The system automatically detected and adjusted the image capture settings at start
up and will continue to adjust every 60 seconds during operation (interval is configurable). The system’s goal is
to produce the best quality captured image given the source equipment used. Generally no further
configuration tweaks are needed.
22
VGADVI Recorder Pro User Guide
Step 4: Configure the channel
Step 4: Configure the channel
Now that you have confirmed the system sees your source it is time to add and configure a channel for
output of your source. Channels expose your sources to your streaming users and prepare the sources for
recording.
By default, when you add a channel, the system names it the same name as its source. If you changed the
source name in previous steps, your new channel's name will reflect the new name.
To add a channel for your source:
1. In the Admin panel, click Add channel from the Channels section; a new channel is created and the
channel configuration page opens.
2. From the Use video source drop-down list, select your source.
3. Click Apply.
To review and configure the channel:
1. From the Admin panel, scroll to the Channels section.
2. Click the link for your channel; the channel expands.
3. Click Encoding for your channel.
4. No need to change anything right now. Review some of the default settings. The four most useful
settings to know about are codec, frame size, frame rate and bitrate.
a. The codec is set to H.264 by default.
b. The frame size should reflect the resolution provided by your source. You can set it to something
different by typing in the fields or selecting an option from the different sizes shown. Scaling the
image (making it larger, smaller, or different aspect ratio) takes some processing power, so it’s
always best to leave this at the value detected by the system unless you know it is wrong or
know you need to scale the size.
c. The frame rate limit is set to 30. This means the system won’t spend extra computing time to
attempt to receive more than 30 frames per second. For perspective, NTSC TV signals use 24
frames per second and most hand-drawn animations show only 12 unique frames per second.
d. The bitrate is set to automatic, and the system will determine the best value.
5. Click Status for your channel.
6. Notice the Stream Info section has an item named Video that reflects the four settings reviewed in
prior steps (the frame rate is specified as <resolution size>@30 for 30 (frames per second). It also
provides an indication of the current actual frame rate.

Connect via persistent static IP address
Your VGADVI Recorder Pro has a default persistent static IP address, also known as the recovery IP address.
If ever you need to set it up on a network that does not support DHCP, or you need to recover from a
previous static IP address setting, you can use this method to connect directly to the system for
configuration.
To perform this procedure you will need a workstation computer for which you are able to modify network
settings.
The VGADVI Recorder Pro is pre-configured with the following static address defaults:
l IP Address:
192.168.255.250
l Netmask:
255.255.255.252
l Username:
admin
l Password:
your admin password (by default set to no password)
To access the VGADVI Recorder Pro's Admin panel via the persistent static IP address:
1. Establish an Ethernet connection between the VGADVI Recorder Pro and the workstation by one of the
following methods:
a. Connect the system to a local Ethernet network shared with the workstation.
b. Connect the system directly to the workstation’s Ethernet port using either a regular or a
crossover Ethernet cable.
2. Record the network settings of the workstation being used to connect to the VGADVI Recorder Pro so
that they can be restored later.
3. Temporarily change the network configuration on the workstation to the following:
a. Use Static IP assignment
b. IP address: 192.168.255.249
c. Subnet mask: 255.255.255.252

Operator
The operator account allows users limited VGADVI Recorder Pro configuration control.
If an operator does not have the privileges to apply a particular configuration in the Admin panel, the Apply
button appears grayed-out in color and is not clickable (as shown in the image below).
The operator account is intended for an operator to configure sources, control recordings (start and stop);
rename, download and delete recordings; switch layouts while live streaming or perform network diagnostics.
Viewer
The viewer account is for all end-users who are permitted to view the streamed channels. By default, when
there is no password, users are not prompted for a username and password when viewing a channel. The
viewer username and password prompt appears only when there is a viewer password set.
In addition to the global viewer account, each channel can set a viewer password that overrides the global
value. See Restrict access to streams for viewers.

Set or change user passwords
By default, admin, operator and viewer have no assigned passwords. Both the admin and the operator user
have access to the Admin panel, so you should always set a password for both admin and operator accounts.
Refer to your system administrator for your organization’s specific password requirements.
If the admin password is defined and the operator password is undefined, then the operator uses
the admin password by default.
In addition to setting global passwords for viewers, you can also set access passwords and IP restrictions on a
per-channel basis from the channel's Streaming page. See Restrict viewers by IP address.
Passwords are case sensitive and can use all alpha-numeric keys in the ASCII range. Your password can be up
to 255 characters long, but should not include any spaces.
Setting a user’s password causes the user to be logged out. Be ready to log back in with the new
admin password or have operators and viewers log in with the appropriate new password.
Viewers may need to refresh their browser window or press play in their media player.
If you lose the admin password, refer to the section Overcome lost passwords.
Changing the admin password while live streaming disrupts the view of the stream for viewer-level
users. Complete any admin password changes when there is no live stream in progress.
To set a user password:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Select the Access passwords link in the Configuration menu; the password configuration page opens.
3. Highlight and delete the current password for your selected user (the password is currently masked
as dots).
For security reasons, the current password appears as eight dots regardless of password
length, and even if there is no password set.
4. Highlight and delete the confirmation password for the selected user.
5. Select the user’s password field and type a new password for the user.
54
VGADVI Recorder Pro User

User administration
The new password must have between 1-255 alpha-numeric characters or special
characters with no spaces. Passwords are case sensitive.
6. Select the user’s password confirmation field and confirm the new password.
7. Click Apply.
8. If you were logged in as the user whose password you just changed, you are logged out and must log
back in with the new password. If you added or changed the viewer’s password, all viewer’s stream will
pause until they log in with the new password.
If desired, you may specify multiple account passwords on the same page before clicking Apply.
Remove user passwords
If you want to remove passwords for one or more user accounts, you may do so via the Admin panel. If you
don’t remember the admin password, refer to the section Overcome lost passwords.
Note that viewer passwords can be set on a per-channel basis.
Clearing a user’s password will cause that user to be logged out. Be ready to log back in with the
new admin password. If viewers are watching the broadcast when the viewer password is cleared
they will be logged out. Viewers may need to refresh their browser window or press play in their
media player to trigger the login prompt.
To clear a user’s password:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Select the Access passwords link in the Configuration menu; the password configuration page opens.
3. Highlight and delete the current password for your selected user (the password is currently masked as
dots).
For security purposes, the current password appears as eight dots regardless of password
length, and even if there is no password set.
4. Highlight and delete the confirmation password for the selected user.
5. Click Apply.
6. If you were logged in as the user whose password you just cleared, you are logged out and must log
back in without a password. If you cleared the viewer’s password, all viewer streams will pause until
they log in without a password.

4. Click Apply.
Overcome lost passwords
If you have lost the password for the operator or viewer account, you can log in to the Admin panel and reset
the password using the procedure described in Set or change user passwords.
If you have lost the admin password and you have remote support enabled on the system, you can contact
Epiphan support to request a remote password change. See Support. If remote support is disabled, you will
need to return the system to Epiphan for password recovery. Contact Epiphan support to discuss this option.
Configure LDAP
You can use the Lightweight Directory Access Protocol (LDAP) for authentication into the system. Specify user
roles by using group DNs for users who log in as the administrator, operator or as a viewer.
The system has only one admin user and one operator: LDAP users log in as either the admin or
operator, they do not have their own private profiles.
When enabled, LDAP authentication is an alternative to the regular system usernames and
passwords. You may still login as admin, operator or viewer using the passwords for those
accounts. Furthermore, any LDAP users with the name admin, operator or viewer are ignored. The
local accounts are used instead.
For security reasons, you should configure passwords for the local accounts. See Configure
LDAP.
These instructions assume you have a pre-configured LDAP server. The server must support anonymous
binding or have a special bind account with search access privileges. (Note that Active Directory does not
support anonymous binding.)
LDAP referrals, restrictions and failovers are not supported.

2. Select the Access passwords link in the Configuration menu; the password configuration page opens.
3. Scroll to the LDAP authentication section.
4. Click the Enable LDAP authentication checkbox to enable LDAP authentication (or uncheck to
disable).
5. Specify the server IP address and (optional) port for your LDAP server (i.e. 192.168.1.101:389) in the
Server address[:port] field.
6. Use the Connection encryption drop-down to specify the type of encryption, if any used by your
LDAP server.
Connection

Description/Default port used
No Encryption
No encryption is used to connect to the LDAP server. The default port is 389.
SSL
SSL encryption is used to connect to the LDAP server. The default port is 636.
TLS/STARTTLS
The connection is initially unencrypted then upgraded to TLS encryption is
used. The default port is 389.
7. Specify the fully qualified DN and password for LDAP bind in the Bind DN and Bind password fields.
(The password masked as dots on the screen.) These fields are only needed if your LDAP server does
not support anonymous binding.
8. In Base DN, specify the baseObject in which to search for entries. The system will search this object
and the whole subtree starting at the base DN.
9. By default the search attribute is uid, which is suitable for a unix environment. Specify a different value
in the Search attribute field, if needed. For Active Directory environments, specify
userPrincipalName. The value of this attribute must be unique in the Base DN.

username (i.e. username@domainname) in addition to his LDAP password.
Users are required to authenticate once to the system and one time per channel they view.
Therefore users see a prompt to log in to the system (the system name is shown) and a second
time to log in to the channel (the channel name is shown).
In one case, LDAP replaces the local viewer account instead of working side-by-side with it.

Change the logged-in user
When you log in to the Admin panel as admin or operator, your browser remembers this configuration and
automatically logs you in as the same user when you go back to the site.
Sometimes you need to change from operator to admin, or vice versa.
To change the logged-in user:
1. Exit your browser completely, open an incognito/private window in your browser, or open a different
browser (i.e. Internet Explorer, Chrome, and Safari are different browsers).

3. You are prompted for a username and password.
1. Click the logout button at the top right of the screen (beside your user name); you are logged out.
Some browsers may require you click the button twice before the log out action executes.
Restrict viewers by IP address
The VGADVI Recorder Pro permits you to restrict which computers can access broadcasts by building a list of
allowed and/or denied IP addresses. You can do this at a global level for the system and can also override
these settings on a per-channel basis. Both global and per-channel configuration procedures are described
below.
IP address restriction is valid for the viewer only and does not affect the Admin panel or the
mobile configuration interface.
If your viewer account has a password, your viewers must connect to the system from a computer (or
gateway) with a permitted IP address and must also supply the username (viewer) and password before they
can view the broadcast.
To restrict access by IP address you need to know the IP addresses, or range of addresses for your viewers. By
default all IP addresses are allowed to connect to the broadcast.
If you’re not familiar with creating allow/deny lists, refer to the examples below this procedure for assistance
with crafting your lists.
To restrict viewers by IP address:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Select the Access passwords link in the Configuration menu; the password configuration page opens.
3. Type allowed IP addresses or address ranges in the Allow IP’s field. Separate addresses with a comma.

4. Type denied IP addresses or address ranges in the Deny IP’s field. Separate addresses with a comma.
5. Click Apply.
To restrict viewers of a specific channel by IP address:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Select the Streaming link for the desired channel; the streaming configuration page opens.
3. From the Access Control drop-down, select Use these Settings; local password and Allow/Deny IP
lists are enabled.
4. If desired, type a password for the viewer in the Viewer Password field.
5. Type allowed IP addresses or address ranges in the Allow IP’s field. Separate addresses with a comma.
6. Type denied IP addresses or address ranges in the Deny IP’s field. Separate addresses with a comma.
7. Click Apply.
If a user attempts to connect to the stream from a disallowed IP address, access is denied. If connecting by
internet browser, the message "IP address rejected." is displayed.

IP restriction examples
Allow list with distinct IP addresses
The simplest allow/deny list is to use the list of known IP addresses to craft a list of allowed IP addresses. All
other addresses are denied access to the broadcast.
For example if your system is accessible on your local area network (LAN) and you want to make sure only the
CEO’s specific desktop, laptop and tablet computers (with IP Addresses 192.168.1.50, 192.168.1.51, and
192.165.1.75, respectively) can connect to the broadcast, construct the following allow list:
Allow: 192.168.1.50, 192.168.1.51, 192.168.1.75
Allow list with a range of IP addresses
Sometimes you’ll want a range of computer IP addresses to connect to your system. This may happen when
you have one range of IP addresses assigned to desktop computers (i.e. in the range 192.168.1.1 to
192.168.1.100) and another range assigned to boardroom computers (i.e. the range 192.168.1.200 to
192.168.1.250). If you only want the boardroom computers to connect to broadcasts from the system you
can specify the range of boardroom IP addresses rather than needing to type in each individual address. The
allow list looks as follows:
Allow: 192.168.1.200-192.168.1.250
Note that we could have specified two of the IP addresses in the previous example as a range.
Allow list with a range of IP addresses and one or more specific IP addresses
Putting the first two examples together, we want to permit access to IP addresses in the range of boardroom
computers (192.168.1.200-192.168.1.250) and also want to add the desktop, laptop and tablet computers
of the CEO (IP addresses 192.168.1.50, 192.168.1.51, and 192.168.1.75, respectively). Note the first two IP
addresses are consecutive, so they can be added as a second range. Add these IP addresses to the list as
follows:
Allow: 192.168.1.200-192.168.1.250, 192.168.1.50-192.168.1.51, 192.168.1.75
Your list can have multiple ranges and multiple distinct IP addresses, provided they are separated by commas.
Deny list with distinct IP addresses
Another simple allow/deny list is to use the list of known IP addresses to list specific denied IP addresses. All
other addresses are allowed access to the broadcast.
61
VGADVI Recorder Pro User
Guide
User administration
For example imagine your system is accessible on your local area network (LAN) and you want to allow any
computer on the LAN can access the stream except your publicly-accessible boardroom (with IP address
192.168.1.211). You can use the following deny list (leave the allow list empty) to permit all computers except
the boardroom computer:
Deny: 192.168.1.211
As with allow lists, your deny list can specify a range of IP addresses, and can specify multiple ranges or distinct
IP addresses in a comma-separated list.
Allow list with a range of IP addresses, distinct IP addresses and an exception
Building on the previous examples, consider the situation where you want the CEO’s computers
(192.168.1.50, 192.168.1.51, 192.168.75) and all boardroom computers (192.168.1.200-192.168.1.250)
to access the broadcast, with the exception of the public boardroom computer (192.168.1.211). Use both
allow and deny lists to create the rule as follows:
Allow: 192.168.1.200-192.168.1.250, 192.168.1.50-192.168.1.51, 192.168.1.75
Deny: 192.168.1.211
Both lists can have multiple ranges and multiple distinct IP addresses, provided they are separated by
commas.
Deny list with a range of IP addresses
Converse to the previous examples, consider the situation where you want every computer on the network to
access the broadcast, with the exception of the CEO’s desktop, laptop and tablet computers. Additionally,
boardroom computers should not be permitted with the exception of the cafeteria computer (IP address
192.168.1.222).
The deny list is an "exception" list for the allow list. So to craft the rule described above we need to allow all the
computers in the local subnet, then deny specific sub-ranges including two groups of boardroom computers
ensuring the cafeteria computer's IP address is not in the deny list:
Allow: 192.168.1.1-192.168.1.250
Deny: 192.168.1.200-192.168.1.221, 192.168.1.223-192.168.1.250, 192.168.1.50-192.168.1.51,
192.168.1.75

Tether to a mobile network
The VGADVI Recorder Pro supports tethering to a mobile device via USB. Tethered networking can work sideby-side with Ethernet routing and either networking system can be a back-up for the other.
When the system falls over to the backup network type (i.e. from Ethernet to mobile, or vice
versa) all streaming sessions with clients or servers directly connected to the system are closed
and the clients will need to reconnect. You may need to provide a new stream URL (containing the
new IP address) to your viewers. See the channel information page to get the new stream URL.
By contrast, actively published streams are closed and reconnected via the secondary network
(mobile or Ethernet) automatically, permitted the required publishing server is accessible from the
new network.
To configure tethering to a mobile network:
1. Configure the mobile device to allow tethering via USB.
2. Connect the mobile device to the VGADVI Recorder Pro with a USB cable.

Configuration presets
Configuration presets are the perfect solution for backing up your system configuration, for situations where
you have changing configuration requirements for your VGADVI Recorder Pro or when you are managing a
number of systems and you want them to have similar configurations.

Configuration presets overview
Configuration presets make it easy to manage a group of VGADVI Recorder Pro systems or to use your
VGADVI Recorder Pro in a variety of situations without needing to reconfigure it.
Configuration presets divide the system's settings into the following configuration groups. (For a complete list
of what is included in each group see Configuration presets overview.)

Configuration presets overview
Using the Configuration presets section of the Maintenance page, you can create and save configuration
presets using any number and combination of the configuration groups. Mix and match the settings groups
saved together to create sets of configuration settings needed for each situation. You also always have a
special Factory default configuration preset (which cannot be erased) to help you return to factory
configuration without destructively erasing files saved to the system hard drive (see Configuration presets
overview
When you are satisfied with the set of configuration items, you can save it, apply it again at a later date and
even download it, then log into another VGADVI Recorder Pro system and apply it there.
It's important to note that configuration presets are applied over existing settings. They affect only the
settings groups included in the preset; all other settings are unaffected. Read the Configuration presets
overview section carefully to understand caveats around using configuration presets.
Configuration presets in action
Here's an example of how configuration presets can make it easy to manage a fleet of systems.
Imagine a company is hired to do the following tasks at a big conference:
l Stream and record each conference session with a picture in picture layout that includes identifying
information about the presenter in the metadata and the background image for the stream.
l Stream and record the keynote with pre-show content, post-show content and live switching between a
number of different layouts during the show.
l Automatically upload backups of the keynote and session recordings.
The company will meet these goals with a fleet of VGADVI Recorder Pro systems.
Before the show, they upload the required backgrounds and create channel configuration presets for the
keynote and each conference track. Each of these is saved as a named preset (for example Keynote, Session 1,
Session 2) with all the pieces needed for that session, including the background image(s), metadata, streaming
settings, etc.
They also create network and automatic file upload (AFU) presets for each of the home and remote locations.
Once at the conference, they upload these configuration files to the fleet of systems and apply the network
and AFU preset. Before each conference session they need only apply the appropriate preset to configure the
system correctly for the session.

Channel configuration includes background and other image files used. If these files aren't
present when the configuration preset is saved, the save function will fail. Be careful when
deleting background images and logo files.
Let's take a closer look at the types of presets they make:
Internal network and AFU preset
The company uses this preset when configuring and testing from their corporate network. It uses a static IP
address on their corporate network and AFU that uses ftp to upload to a local ftp server.
The internal network

changes only the network and AFU settings (using a conference-specific IP address and secure file transfer to
an ftp server).
When applying this configuration preset, all other information including passwords, date/time, channels and
source configurations, remains the same.

Conference breakout session and keynote presets
The company creates one preset per session and one for the keynote. Each preset includes all the files and
everything needed to recreate a custom channel configured with the layouts and backgrounds needed for the
session.
They upload these presets at the beginning of the conference and apply the correct one prior to each
conference session starting. When they apply the preset, all other preset groups remain unchanged; the
preset only affects the channel(s) and their configuration. This preset includes a channel the background file

Note that after applying a preset, files from the previous session remain present on the system and continue
to upload via sftp (if not yet complete), but the channels reflect the newly loaded session's background file
name and presenter name.

Create a configuration preset
You can create as many configuration presets as you need, however there is a limit to the amount of space
you have for configuration presets (256 MB). For each configuration preset you create, you get to name the
preset and choose the groups of setting types to include. See Configuration groups for more information
about the groups of configuration items.
It's good practice, after completing configuration of your VGADVI Recorder Pro, to save a full backup (with all
groups selected) so you may restore it at a later date (i.e. after a change that wasn’t wanted or after a factory
reset).

Create a configuration preset
Note that configuration presets that include network or system settings require a system
reboot when applied.
To create a configuration preset:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Select the Maintenance link in the Configuration menu; the maintenance page opens.
3. Scroll to the Configuration presets section.
4. Type a description for your preset in the Name field.
5. Ensure only the desired configuration groups are selected from the Sections group. (For full system
backup, select all groups.)
6. Click Save; your configuration preset appears in the list.
If you try to save a configuration preset but one or more of the related image files is missing,
you'll see an error. You'll be unable to save the preset until the missing files are restored or the
layouts referencing the files are changed to remove the references.
If you try to save a configuration preset but there isn't enough space, you'll see an error
message. You'll need to delete some presets before proceeding.

Apply a configuration preset
There is a maximum amount of 256 MB available to save configuration presets and a maximum
size of 128 MB for a single configuration preset.
Apply a configuration preset
When you apply a configuration preset, the system settings for all included configuration groups are updated.
Other settings on the system are not affected. For example if you apply a preset that includes the
configuration groups channels and automatic file upload, your network settings, passwords, time server,
source configurations, etc are not modified. Similarly, if you apply a configuration preset that has only
network settings included, only the network settings change.
If you apply a preset that has the network or system configuration group, a reboot is required. If you apply
a preset that has the EDID configuration group, the system may appear unresponsive for a short time while it
applies these EDIDs to the video grabbers.
You can verify which configuration groups are included in a preset by looking at the list to the right of the
configuration preset name. The term 'all' means all groups are included. Otherwise groups are listed
individually.
You may apply multiple presets one after another. If you apply two (or more) configuration
presets that include a particular configuration group, the settings (for that group) from the last
applied preset are the active settings. In short, last in wins.
To apply a configuration preset:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Select the Maintenance link in the Configuration menu; the maintenance page opens.
3. Scroll to the Configuration presets section.
4. Click the Apply button next to the configuration preset you wish to apply.

Apply the Factory default configuration preset
Your VGADVI Recorder Pro comes with a special factory default configuration preset. This configuration
preset cannot be erased and is always presented at the top of the configuration presets list. It contains all
possible configuration settings groups.
Using the Factory default configuration setting is similar to using the Factory reset method (see Perform
factory reset) with a few important differences.
In short, the Factory default configuration preset is less destructive than Factory reset. This table

Configuration preset considerations
Configuration presets are groups of settings applied to the system, leaving other settings intact. The following
considerations will help you get the most from your configuration presets.

VGADVI Recorder Pro User
Guide
Configuration preset considerations
Channel and recorder index number behavior
Each channel and recorder has an index number. The first channel created on a system is channel 1,
subsequently channel 2, 3, 4, etc. Recorders are also created starting at index 1 with numbers incrementing as
new recorders are created. The channel (or recorder) index number is found to the left of the channel or
recorder name in the Admin panel:
Configuration presets that contain the channels configuration group specify the channels in the preset by
their index number. This means if you have channels 1, 2, 3 and 4 when you save your preset, applying that
preset will overwrite the configuration of your current channels with indexes 1, 2, 3 and 4. If prior to applying
that preset you also had channels with indexes 5 and 6, the configuration settings for those two channels are
erased when the preset is applied (because the preset only has 4 channels).
There are three areas where channel (and recorder) index numbers affect what happens when applying
configuration presets. Read Recording and streaming statesRecorded files (in channels and recorders) and
Deleting channels for more information.
Recording and streaming states
The Configuration groups section of this chapter shows that each channel and recorder's recording and
streaming state is included in the channels configuration group. This means that if a channel is streaming or
a channel (or recorder) is recording at the time you create a configuration preset, it will immediately start
recording (or streaming) when you apply that preset. Similarly, if a configuration preset is saved when
channels or recorders are not recording (or streaming), those channels and recorders will not be recording
(streaming) when the preset is applied
This means a channel or recorder may stop recording or streaming as a result of applying the
preset.
For example, when applying a preset with channel 3 set to record (the same example applies for streaming):
85
VGADVI Recorder Pro User
Guide
Configuration preset considerations
l If channel 3 exists prior to applying the preset and is already recording, the file will continue recording
uninterrupted unless the recording file type is different in the preset (in which case a new file is started).
l If channel 3 exists prior to applying the preset and is not already recording, it immediately begins
recording.
l If no channel with index 3 exists prior to applying the preset, the channel is created and it immediately
begins recording.
Recorded files (in channels and recorders)
Channels and recorders keep a list of files recorded in their Recordings section of the Admin panel. These
files remain on the system even if the channel or recorder configuration is changed or removed as a result of
applying a configuration preset.
For example, prior to applying your configuration preset, you have channels with indexes 1, 2 and 3; each of
these has five recording files. When you apply a configuration preset that has channels with index 1 and 2
only, you'll notice those channels each still have the same 5 recording files. Channel with index 3 is no longer
present, but the files are not lost!
Overwritten channel files are still available. To access and download/delete these recorded files, enter the
following into the address bar: http://<deviceIP>/admin/channelN/archive or
http://<deviceIP>/admin/recorderN/archive, where N is the index of the removed channel/recorder.
For example, if a Channel with index 3 is no longer present, its corresponding files can be accessed by
entering the following into the address bar:
l http://192.168.0.183/admin/channel3/archive
If you now create a new channel with index 3 (or load a preset that contains a channel with index 3), you'll find
it starts with five recorded files in the Recordings section. These are the same recorded files that existed at
the start of this example.
Furthermore, if you delete any of the recordings, you are deleting the only instance of those files. Using our
previous example, if you delete one of the five recordings from channel index 1, you'll find that even after
applying different presets channel 1 will have only four recorded files.
Deleting channels
Recorded files are stored on the system based on their channel or recorder number. All files saved for channel
index 1 are in one folder, and all files for recorder index 2 are in another. When you delete a channel (or
recorder), you permanently delete all recordings for that channel (or recorder) even if those recordings were
made while a different preset is applied.
86
VGADVI Recorder Pro User
Guide
Configuration preset considerations
Applying a configuration preset with a different set of channels or recorders is not the same as
deleting a channel.
When deleting a channel or recorder that has recorded files, the Admin panel warns you of other
configuration presets that use the same channel or recorder index numbers. When you see this prompt, we
recommend you take a moment to look through the Recordings list to make sure you're OK to proceed with
permanently deleting all the recorded files.
Branding content
Branding content files (logos, background images, etc) are included in your configuration presets and must be
present on the system when creating a preset that includes the Channels group, otherwise a failure is
reported.
Configuration presets are not user profiles
Configuration presets should not be confused with the concept of user profiles. Specifically, the following
issues arise from trying to use configuration presets as user profiles:
l recorded files are not removed between application of configuration presets (users could see each
other's files)
l configuration presets can be overwritten and deleted with no password (users could affect each other's
presets)
l branding and recorded files can be deleted, affecting more than just the currently applied configuration
presets (users could erase branding or recordings belonging to other users)
l applying a configuration presets does not clear the settings from groups not part of the preset (user
information is not private)

PART 2: Capture
Capturing is the process of taking the signals from your video and audio sources and encoding them in a
format that is ready for streaming and recording.
If you followed the quick start guide, you're already capturing, streaming and possibly recording your sources.
The section of the guide helps you fine tune and troubleshoot the capturing process.
When using VGADVI Recorder Pro, you can stick to all the default capture and encoding settings, or you tweak
them to set the up exactly as you like.
You can capture a single source at once, capture multiple sources in a custom channel or even switch between
sources or groups of sources (layouts) while streaming and recording.
Techniques for creating channels to capture, stream and record a single source; to create custom channels
with multiple sources and multiple layouts; and how to switch layouts while capturing are all described in this
section.

What is a channel?
What is a channel?
VGADVI Recorder Pro uses Channels to organize and display content captured from DVI, VGA, HDMI, SDISVideo and audio.
Channels make your sources (DVI, VGA, HDMI, SDI, S-Video and audio) available for streaming and
recording. You choose how you want to configure your sources (and extras like images and text overlays) into
layouts within your channel.
DVI2PCIe cards do not support audio over HDMI. VGADVI Recorder Pro systems with DVI2PCIe
cards will not be able to capture audio through HDMI sources.
VGADVI Recorder Pro gives you a lot of control over how your sources are streamed. You are not limited to
creating a Channel list that is a one-to-one reflection of your Sources list. You can make channels from some
or all of your sources and you can add the same source to multiple single-source or multi-source layout
channels.
For example, you could use the same source in all three of these situations, concurrently:
- as the only source in Channel 1 at 1080p, 30fps, 10,000 kbps;
- as the only source in Channel 2 at 720p, 15 fps, 2,000 kbps;
- in Channel 3 as part of a multi-source layout with picture in picture.
All channels can be streamed and recorded simultaneously. Following the example above, you could record
any combination of those three channels, and stream one, two or all three of them using any available
streaming methods.
In addition to creating multi-source channels, you can customize your channels by adding images, company
information, corporate colors and time stamps. VGADVI Recorder Pro has a visual layout editor to help you
create exactly the layout you want to stream.
For each channel you create, you can use the layout editor to create one or more channel layouts. Then, while
recording and/or streaming, you can switch live between different layouts. To learn about creating layouts,
read Create a custom channel and Custom channel layout editor. To learn how to do live video mixing / live
video switching, see Live video mixing / switching.

You can also view channels and perform live switching using the Epiphan Live control
interface. See Configuring Dashboard panels for visual confidence monitoring and
Switching while live streaming and recording for more information.
You can now create and upload customized “No Signal” images for use in your channels. These images are
assigned to a specific source and display in any channel where the source is used but has no input detected.
For more information on how to create a "No Signal" image, see Add a No Signal image to a source .
Through channel configuration and fine-tuning you can maximize your stream quality, minimize your
processing requirements and bandwidth. You can also specify how the video is presented and streamed to

Create a simple channel
Channels arrange the output from sources into a viewable and recordable stream. Although there are may
ways you customize a channel, this procedure walks you through the most basic channel setup with a
single source. For multiple-source channels and advanced layout editing see Add channel metadata. (You
can always update this channel later to use multiple sources or multiple layouts.)
After creating this channel you'll be ready to stream it using the system default settings. Instructions to
configure encoding, branding and CDN streaming are described in separate procedures.

Your channel is ready for basic streaming and recording.
By default (on a new channel), when the source doesn't have a 16:9 aspect ratio, the system
automatically detects the correct aspect ratio and updates the layout after you leave and return
to the layout editor screen. This happens because the encoding page has the Use current signal
resolution as frame size setting selected by default. If you want to change the aspect ratio for
your channel, see Configure encoding .

Create a custom channel
There are a lot of creative things you can do next with your channel, including creating more layouts and
editing this layout to add images and more sources. See Create a custom channel for more information.
Create a custom channel
VGADVI Recorder Pro has two styles of channels:
1. Simple channels with a single source that fits the full screen, as discussed in Create a simple channel.
2. Custom channels with one or more layouts, sources, background matte color and images.
Both types of channels are created using the same interface. In fact, custom channels are the same thing as
simple channels, but they're described separately in this manual because they are more complex. We call a
channel a custom channel (or custom layout channel) when it has multiple sources, image elements, multiple
layouts or any combination of those items.
So the only distinction between simple channels and custom channels is whether you choose to add any extra
elements to the channel.
When making simple channels, your source takes up the whole screen, but with custom channels, you can
organize sources, pictures and text overlays in different locations on your screen. We call these layouts, and
each custom channel you create can have multiple layouts.
If you want to change the way things appear in your stream while streaming (aka video switching or video
mixing), you'll need to create one layout for each of the views you want for your stream. Later, while you are
streaming, you can switch live between the layouts using the Admin panel.
If you're planning to do live switching with your channel, we recommend you set the frame size to
a fixed size instead of using the default automatic detection of source frame size. Setting the
frame size to a fixed value ensures you don't experience any stream interruptions if the source
frame size changes due to layouts that contain a single source that has a different frame size than
those in other layouts.
As you saw when creating a simple channel, the first thing you need to do is create your (first) layout. Before
getting started with custom channel layouts we recommend you review the Custom channel layout editor and
get some inspiration from our Custom channel examples. Then use the remaining topics in this section to help
you create and configure your perfect custom channel layout(s)!

Once you have your layouts created, read about Live video mixing / switching to learn how to change between
layouts while streaming and/or recording.
Each layout you add to your channel adds a bit of overhead on VGADVI Recorder Pro- and more
complex layouts take more resources. So it's a good idea to make sure you delete any layouts
you're not using.
Custom channel layout editor
The visual channel layout editor gives you full control on size and position of the pictures, sources and text
overlays you add to your channel.
You can edit existing channel layouts (even ones you initially created as simple channels) or you can create a
new channel or a new layout within a channel to work with. To add a new layout, see Create a custom channel
or layout.
To select a layout for editing:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Select your channel from the channels menu and click Sources for the channel.
3. Select the layout you want to edit by clicking anywhere in the layout row; the layout editor shows the
current state of the selected layout for your channel and the row for the layout you're editing is
highlighted green.

Create a custom channel
The heart of the channel layout editor is the layout area, which has the same frame size and aspect ratio as
your stream. As you add items to the layout, they appear in the layout area. The currently selected item is
presented in full colour while other items appear transparent.
To position the items you can use the mouse to click and drag, or you can use the manual positioning values
to set a location as a percent of the screen (by typing a value followed by the percent sign, e.g. 4%) or in pixels
(by typing a value followed by px, e.g. 16px).
You can resize items by clicking and dragging the red and white circles at the corners of the items or by using
the manual positioning values. For example, entering 0% in all four of the outside boxes will stretch the item
to the full size of the layout area.
You can modify the settings for each item by clicking the row. The item's settings box appears. See Add an
image (custom channel), Add a video source (custom channel) and Add a text overlay (custom channel) for
more details on item settings.
Audio source selector and save button

Time to get started on your own layouts! See:
l Create a custom channel or layout
l Custom channel layout editor
Create a custom channel or layout
We call a channel a custom channel (or custom layout channel) when is has multiple sources, image elements,
multiple layouts, or any combination of those items. Custom layouts give you full control on size and position
of the pictures, sources and text overlays you add to your channel.
Use this procedure to help you create a new channel or layout, then use the related procedures to add
elements to your layout.
If you're planning to use live switching, we strongly recommend you rename the channel rather
than using the default channel name (Rename a channel). See the note at the bottom of this
topic to avoid streaming and recording issues resulting from adding or deleting layouts when live
switching.
To create a new custom channel (with default layout) or add a layout to an existing channel:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Do one of the following to make the Sources page appear:
a. select your channel from the channels menu and click Sources for the channel; or
b. select the Add channel link to create a new channel.

Important note for channels with multiple layouts
By default (and historically), VGADVI Recorder Pro's channels are named automatically based on the content
in the channel.
When a channel has only one layout, and that layout has only one source (regardless of whether or not there
are pictures or overlays in the layout), the channel name is the same as the source name.
108
VGADVI Recorder Pro User
Guide
Create a custom channel
For example: By default, a channel with one layout that has HDMI-A in it will be named HDMI-A.
When you add a second layout to a channel, the channel name changes to a generic name Channel X (where
X is the channel index number). Normally this wouldn't pose any problem, but the changing name does have
some side effects: the stream is stopped and restarted, and the channel's recorder (if recording) is stopped
and a new file is started.
Furthermore, when you delete layouts in a channel until there is only one layout (with one source) left, the
channel name reverts to the source name.
To avoid any issue with changing channel names on channels where you'll have more than one layout, we
strongly recommend you rename the channel to a custom name (Rename a channel. This will ensure no
automatic channel name changes.
Add a video source (custom channel)
A source needs to be added to a channel before the channel is ready to stream. In the case of custom
channels with layouts, you can add one or more sources to the layout area.
When adding more than one source to a custom channel, we recommend configuring the
channel to use a fixed resolution instead of using the current signal resolution as the frame
size (see Configure encoding ). A fixed channel resolution ensures that your channel will
display properly in all preview modes (, Epiphan Live and Admin panel).
You can add a source to a layout on an existing channel or you can create a new channel. If you're not sure
how to create a channel or a layout, start by reviewing the first few steps in the topic Custom channel layout
editor or start with Create a simple channel.
To add a source to your layout:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Follow the steps in Custom channel layout editor or Create a custom channel or layout to get to the
channel layout editor.
3. From the channel layout editor, click Add item; a drop down box appears. (If you have any other items
already in your layout, the new item appears at the top of the list.)

For example, if you added your video source over a text overlay, the video source could conceal
the overlay. To fix it, drag the video source item below the text item in the list, or vice-versa.

A note about item positioning and sizing
There are four ways to position and size items in the layout area
1. using the mouse
2. using the keyboard
3. using the manual positioning values with percents
4. using the manual positioning values with pixels
To use the mouse:
Click and drag to move the item. Click and drag the red and white circles to resize the item as you wish.
Using this method you can make quick changes that are in increments of approximately 5% of the
width or height of your layout area. For more refined movements, hold the down the Ctrl key on your
keyboard while dragging the item with the mouse.
To use the keyboard:
Use the arrow keys on the keyboard to move the item up, down, left or right in the layout. Changes are
in increments of approximately 5% of the height or width of the layout area. Make more refined
movements by holding down the Ctrl key on your keyboard while pressing the up, down, left or right
keys. You can also hold the Shift key while using the arrow keys to control the size of the item on the
layout. Hold both Ctrl and Shift for fine-grained size control.
Using percents:
Specify a whole number, followed by a percent sign (e.g. 4%) in any of the manual positioning fields.
See Resize and position layout items using percents or pixels (custom channel) for more information.
Using pixels:
If you need to specify an exact amount in pixels (rather than percent) you can type a pixel value in any
of the positioning value squares followed by the characters px (e.g. 56px). You can mix and match
pixels and percents changing only the boxes you want to use pixel values. At any time you can switch
back to percents by typing a percent. See Resize and position layout items using percents or pixels
(custom channel) for more information.

Add an audio source (custom channel)
To stream the audio for a source you need to add it to a channel and make sure audio is enabled in the
channel's encoding page. (Audio is enabled in the encoding page by default.)
There is no need to manually add RTSP audio sources to your channel. When an RTSP stream is
connected to your VGADVI Recorder Pro as an input source, a corresponding audio source is
automatically added to the list of audio sources for your channels, even if there is no audio in the
RTSP stream.
Audio must be added to each layout for your channel. You can use the same audio for each layout, or if you
desire, you can have different layouts use different audio. If you're not sure how to create a channel or a
layout, start by reviewing the first few steps in the topic Custom channel layout editor or start with Create a
simple channel.
To add an audio source to your layout:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Follow the steps in Custom channel layout editor or Create a custom channel or layout to get to the
channel layout editor.
3. Select the audio source(s) you want to add to your channel. Audio sources are mixed together at the
same volume level as one another.
4. When your layout changes are complete, scroll to the bottom of the page and click Save to save your
work.
5. Follow the steps in Configure audio codec to ensure audio is enabled for your channel and to select
your audio settings.

To upload an image
You can customize your channels by adding pictures as backgrounds, overlays or information. Collectively the
images you upload to the system are known as branding images.
For best results always upload images that are already the correct size needed in your layout.
Background images should match the frame size of your channel (frame size is set in the
Encoding configuration page).
There are two ways to upload branding images. You can upload images to the branding page, as described in
this procedure, or you can drag and drop images using the procedure described in Add an image (custom
channel). Note that using the procedure below is the only way to see whether or not you'll be overwriting an
existing image.

3. using the manual positioning values with percents
4. using the manual positioning values with pixels
To use the mouse:
Click and drag to move the item. Click and drag the red and white circles to resize the item as you wish.
Using this method you can make quick changes that are in increments of approximately 5% of the
width or height of your layout area. For more refined movements, hold the down the Ctrl key on your
keyboard while dragging the item with the mouse.
To use the keyboard:
Use the arrow keys on the keyboard to move the item up, down, left or right in the layout. Changes are
in increments of approximately 5% of the height or width of the layout area. Make more refined
movements by holding down the Ctrl key on your keyboard while pressing the up, down, left or right
keys. You can also hold the Shift key while using the arrow keys to control the size of the item on the
layout. Hold both Ctrl and Shift for fine-grained size control.
Using percents:
Specify a whole number, followed by a percent sign (e.g. 4%) in any of the manual positioning fields.
See Resize and position layout items using percents or pixels (custom channel) for more information.
Using pixels:
If you need to specify an exact amount in pixels (rather than percent) you can type a pixel value in any
of the positioning value squares followed by the characters px (e.g. 56px). You can mix and match

Custom overlay text (dynamic)
If you intend your overlay text to change throughout the course of your streaming and/or recording program,
you can use VGADVI Recorder Pro's HTTP API to insert and update system-wide variables in your dynamic text
field as required. For example, you may insert a system variable into your layout to represent GPS coordinates and then use a script to continuously update the co-ordinates contained in your variable as the
exact physical location in your stream changes over time.
122

Create a custom channel
System variable commands can be issued at a frequency of 5 per second, and up to 6 variables may be set in
a single command. After issuing a set command, all channels using the specified variable(s) are updated.
See Control with HTTP commands to learn how to configure system variables for custom overlay text.
To insert a system variable into your overlay text:
1. Access the overlay text feature in your custom layout by following steps 1–5 in Custom overlay text
(static) above.
For example, in the layout below, "gpsvar1" (variable name) contains the text "N103 68201
W765 29712". Inserting the variable name in the text overlay field displays the variable's value
in the custom layout.
To insert the "gpsvar1" variable into your custom layout, simple type %(gpsvar1) into the Text
field under the Text settings header.
The font size of a system variable may change within a text label depending on each variable's
character count. To maintain a consistent font size within text labels, it is recommended you keep
all system variable values set to the same character count (e.g. 10 characters saved to each
system variable).

A note about item positioning and sizing
There are four ways to position and size items in the layout area
1. using the mouse
2. using the keyboard
3. using the manual positioning values with percents
4. using the manual positioning values with pixels
To use the mouse:
Click and drag to move the item. Click and drag the red and white circles to resize the item as you wish.
Using this method you can make quick changes that are in increments of approximately 5% of the
width or height of your layout area. For more refined movements, hold the down the Ctrl key on your
keyboard while dragging the item with the mouse.
To use the keyboard:
Use the arrow keys on the keyboard to move the item up, down, left or right in the layout. Changes are
in increments of approximately 5% of the height or width of the layout area. Make more refined
movements by holding down the Ctrl key on your keyboard while pressing the up, down, left or right
keys. You can also hold the Shift key while using the arrow keys to control the size of the item on the
layout. Hold both Ctrl and Shift for fine-grained size control.
Using percents:
Specify a whole number, followed by a percent sign (e.g. 4%) in any of the manual positioning fields.
See Resize and position layout items using percents or pixels (custom channel) for more information.
Using pixels:
If you need to specify an exact amount in pixels (rather than percent) you can type a pixel value in any
of the positioning value squares followed by the characters px (e.g. 56px). You can mix and match
pixels and percents changing only the boxes you want to use pixel values. At any time you can switch
back to percents by typing a percent. See Resize and position layout items using percents or pixels
(custom channel) for more information.

Set the background color (custom channel)
When you create a custom channel layout, you can select the background color to fill any unused space. For
example you can add a color from your corporate color scheme.
To add a picture to your layout:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Follow the steps in Custom channel layout editor or Create a custom channel or layout to get to the
channel layout editor.
3. From the channel layout editor, click the drop down arrow next to the existing (by default black)
background color; the color picker opens.
4. Pick a new color or type in an RGB value in the field; the color is updated in the layout area.
5. Click anywhere off the color picker to close the picker.
6. When your layout is complete, scroll to the bottom of the page and click Save to save your work.
Resize and position layout items using percents or pixels (custom
channel)
You can position and resize layout items (images, overlay text, sources) using the percent/pixel adjustment
boxes in a channel's custom layout. See Resize layout items and Position layout items.
There are 3 adjustment boxes along your layout's horizontal axis and another 3 boxes along the vertical axis.
You can enter percent or pixel values into checked adjustment boxes (bordered with red) to position and
resize your item(s).
125
VGADVI Recorder Pro User
Guide
Create a custom channel
Percent values are used in adjustment boxes by default, and can be converted to pixels by simply overwriting
the percent value in a given adjustment box and replacing it with a pixel value.
When entering percent values, ensure the suffux "%" is added to your value (i.e. "20%").
When entering pixel values, ensure the suffix "px" is added to your value (i.e. "200px"). A
layout item's total pixel dimensions are a reflection of your channel's frame size, as
configured in your encoding settings (see Configure encoding ).
Unchecked boxes are greyed-out in color and are not directly editable but dynamically change their values to
reflect a 100% total of either the horizontal or vertical axis, depending on values entered in adjacent
adjustment boxes. See the Adjustment boxes for item resizing and positioning table below for more
information.
The values contained in checked boxes (bordered with red) are anchored and do not dynamically adjust their
values.

Resize layout items
The easiest way to resize a layout item is to use the center adjustment boxes (annotated as #3 and #6 in
the image above) on each of the horizontal and vertical axes to set your item's width and height respectively.
If you need to crop your image, see Add a video source (custom channel).
128
VGADVI Recorder Pro User
Guide
Create a custom channel
In the example above, the presenter video source is resized to 60% of the layout's width and 70% of the
layout's height (with aspect ratio maintained). (Alternatively, pixels could be used to resize the layout item in a
similar fashion.)
An important consideration when resizing layout items
Your item will resize automatically if both left and right (or top and bottom) adjustment boxes contain values
(percents or pixels) that exceed the total of 100% (if using percents),or maximum pixel count (if using pixels)
for the corresponding horizontal (or vertical) axis.
For example, if you originally set the width of an item to 50% of the layout area (or 960 pixels, assuming your
item has a maximum width of 1920 pixels in this example) with no values entered in the left and right
adjustment boxes (i.e. the left and right boxes are deselected), the item automatically centers itself in the
layout area with the left and right percents at 25% each (remember – percents are used by default in the
layout editor, even if pixels are used in adjacent boxes). Combined with the 50% (960px) width of the image,
these two 25% (480px) values total 100% (1920px) of the layout's horizontal axis.
If you instead decide to enable the left and right percent boxes and change their values to 30% each (instead
of the current 25%), then the image's width shrinks from 50% (960px) to 40% (750px) to accommodate the
change and maintain a total layout width of 100% (1920px).
Setting the left and right (or top and bottom) percent values so the axis total among the
three percent boxes exceeds 100% will always result in the center percent box value
automatically reducing itself to maintain the 100% total, shrinking your selected layout
item in the process.
Position layout items
Items are positioned in a custom layout by entering values into the left/right and top/bottom adjustment
boxes (identified as #2/4 and #5/7 respectively in the Adjustment boxes for item resizing and positioning
table above). The values entered into these boxes represent a portion of the total percentage (or pixels) of the
layout's width or height.
129

Create a custom channel
Alternatively, you can position your layout items using the keyboard by selecting the item
with your mouse cursor, holding Shift and pressing the arrow keys to move the
selected item by 5% in any direction.
You can also position your item with additional keyboard precision by holding Crtl and
pressing the arrow keys to nudge your item by a very small fraction in the direction of
your choice.
Note that there is no one way to move and resize your layout items. The examples below are simply
descriptions of one or two ways one might resize and/or position layout items.
Example 1: horizontal positioning using percents
To position your item along the horizontal axis, first resize your items if desired (as described in Resize layout
items), then enter a percent or pixel value into either the left or the right adjustment box to shift your layout
item.
For example, using percents to move a layout item with a 60% width as far to the right of the
layout area as possible, you would need to enter 40% into the left percent box to push the item
to the right. The layout item originally takes up 60% of the layout width, so this added 40% shift
pushes the item as far to the right as possible (I.e. 100% of the horizontal axis).
The right adjustment box automatically sets itself to 0% to reflect that there is more no room remaining to
maneuver the image along the horizontal axis any further. (Alternatively, you could reposition the image in
the exact same way by instead setting the right percent box to 0%).
130
VGADVI Recorder Pro User
Guide
Create a custom channel
Example 2: vertical positioning using pixels
To position your layout item along the vertical axis, enter a percent or pixel value into either the top or the
bottom adjustment box to shift your layout item downward or upward, respectively.
For example, using pixels to move a layout item that is set to 756px in height to the top of the
layout while leaving a small margin of background (say 25px), you could either enter "25px" into
the top percent box (to specify the small margin from the top down) or enter 27% into the
bottom percent box (to specify a 27% margin from the bottom up – added to the item's 70%
height this leaves a 3% margin above your layout item.)
As mentioned above, there is no one particular way to use the adjustment boxes for resizing and positioning
of your layout items. The layout editor interface is flexible enough to allow you to manipulate your layout
items any way you see fit. Create the perfect layout for your audience– using percents, pixels, your keyboard
or any combination thereof!

Important note for channels with multiple layouts
By default (and historically), VGADVI Recorder Pro's channels are named automatically based on the content
in the channel.
When a channel has only one layout, and that layout has only one source (regardless of whether or not there
are pictures or overlays in the layout), the channel name is the same as the source name.
For example: By default, a channel with one layout that has HDMI-A in it will be named HDMI-A.
When you add a second layout to a channel, the channel name changes to a generic name Channel X (where
X is the channel index number). Normally this wouldn't pose any problem, but the changing name does have
some side effects: the stream is stopped and restarted, and the channel's recorder (if recording) is stopped
and a new file is started.
Furthermore, when you delete layouts in a channel until there is only one layout (with one source) left, the
channel name reverts to the source name.
To avoid any issue with changing channel names on channels where you'll have more than one layout, we
strongly recommend you rename the channel to a custom name (Rename a channel. This will ensure no
automatic channel name changes.

Configure frame size
By default, for channels with only one layout and when that layout has only one video source, your VGADVI
Recorder Pro automatically uses the incoming source frame size as the stream frame size. Frame size greatly
affects the amount of bandwidth needed to transmit your stream. The larger the frame size, the more
bandwidth you need to stream it. So you may want to keep the frame size the same as your source, or you
may want to apply upscaling, downscaling, stretching, or black bar framing, depending on your needs.
For example:
l if the input signal resolution is 1920×1080 (a 16:9 aspect ratio)
l and stream frame size is set to another 16:9 frame size such as 1280×720,
the smaller stream frame size causes the system to downscale the image and use less bandwidth to
transmit.
Or if you have a widescreen/HD format source but need a 4:3 output frame size, you can add black bars to
the top and bottom of the frame.
The system is designed to provide scaling, however for the best overall system performance
(particualrly when reaching maximum system capacity), configure your source to provide the
correct frame size and avoid scaling.
To configure your stream's frame size:

4. Perform one of the following steps:
Using current signal resolution as the frame size only works for channel layouts with a
single source. If you're using multiple sources, follow the steps below to set your frame
size.
a. Check the Use current signal resolution as the frame size check box. Enabling this feature
greys out the other frame-size configuration fields. The system automatically streams at the
frame size of the input signal. If you change the frame size (resolution) of the input signal after streaming (or
recording) begins your may see interrupted streaming and recording. Enabling this
feature is not recommended for systems where input resolution is changed
frequently.
b. Change the frame size, follow the steps below.
5. Set the Frame size values to reflect the dimensions required for your stream. Some suggested values
cover popular resolutions of cameras and display devices such as monitors, but you may also specify
something custom:
a. Uncheck Use current signal resolution as frame size.
b. Type a frame size in the field; or
138
VGADVI Recorder Pro User Guide
Configure encoding
c. Select an option from the sizes shown, the dimensions will appear in the frame size field.
Scaling occurs automatically (no extra configuration needed) when you make the
dimensions larger, smaller, or a different aspect ratio than the source.
If your channel has a layout with only one source and your source and stream aspect ratios
differ, when viewing that layout, your source is centered in the frame and matte bars are
added to the top and bottom or left and right sides to make up the difference. See
Remove black bars (matte) from the video.
6. If all your changes are complete, scroll to the bottom of the page and click Apply.
If you plan to use layout switching during a live stream, it's best to choose a fixed layout size. This
avoids causing the stream restart due to frame size change when you switch between singlesource layouts that use frame sizes.
Fine tune stream settings
Along with video/audio codecs and frame size, there are other configurable stream settings that affect quality
and bandwidth. Like with frame size selection, values for these settings can be a tradeoff between bandwidth
available and quality for stream viewers.
A table at the end of this section provides additional guidance for the settings
To fine tune your stream's settings :
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Click Encoding for your channel; the encoding configuration page opens.
3. Scroll to the Key frame interval setting.
4. Click the Key frame interval drop-down box to choose how often a key frame (a frame that contains
all the pixels) is sent when streaming the video. The longer the key frame interval the smaller the video
file size, and vice versa.
5. If desired, change the Limit frame rate. The default should be adequate in most applications. While
decreasing the limit may improve system performance, you may need to test different values to
balance video smoothness and processing power.
6. If using H.264 of MPEG4 video codecs, you can increase or decrease image quality by increasing or
decreasing the target Bitrate value. Video with a high level of motion and high resolution, such as a

Table 23 Stream settings guidance
Setting
Description
The key frame interval feature specifies how often a key frame (a frame
that contains all the pixels) is sent when streaming the video. This setting
also impacts how quickly a video moves through the frames when a
viewer uses the search function of their media player.
Increasing the number of seconds between key frames can significantly
Key frame interval
reduce your bandwidth and system resource usage with minor impact to
your video quality. A good rule of thumb is to keep the interval between 2
to 3 seconds and decrease the key frame interval as the motion increases.
Try different settings and note changes in the video quality. If your video
quality is poor and jittery you may need to decrease the interval between
key frames. If you have unlimited bandwidth and system resources you
can choose an option to stream key frames only.
Frame rate reflects the number of images captured by the device per
second. Reducing the frame rate reduces bandwidth usage, and vice versa.
The system's ability to maintain a set frame rate is based on several
factors, for example:
l overall system load affects the ability for the device to process
pixels;
Frame rate
l available network bandwidth;
l the source and stream frame size (resolution);
l the type of motion that is captured; and
l number of users accessing the stream.
When adjusting the frame rate, you may need to try different values to
achieve the best outcome.
In general, higher bitrate mean higher image quality in the stream, at the
cost of higher bandwidth needed to transmit it.

Live video mixing / switching
Live video mixing / switching
VGADVI Recorder Pro supports live video mixing (also known as live video switching) while you are capturing,
streaming and recording. Video mixing is a great way to create dynamic content for your viewers and
recordings. With VGADVI Recorder Pro, switching happens in less than half a second ( < 500 ms)!
This means you can start your stream with a video source showing a countdown, move to a single-camera
view, then switch between multiple cameras or multiple layouts with more than one source, and end again
with a thank you message for attendees. (Layout switches made in your channel are reflected in both the live
stream and recording. )
For example, your stream could look like this:
Before you can switch between layouts, make sure you have your custom channel with layouts created. See
Create a custom channel or layout.
Now on to the fun part! There are two ways to perform live switching. You can use either the Admin panel or the Epiphan Live control
interface.
Performing live switching in one interface (e.g. Epiphan Live) does not dynamically update
the visuals in the other interface (e.g. the Admin panel). The other interface must be
manually refreshed to accurately reflect the current live switching layout information.
Switching / mixing using the Admin panel
Switching live video inputs, or video mixing, is fast and easy using the Admin panel. For best results, you may
wish to be in a location where you can see the live action, and have a solid understanding idea of what is in
each of your layouts. Good layout names can help with this. See Rename a layout (custom channel).
To do live video mixing:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Follow the steps in Custom channel layout editor or Create a custom channel or layout to get to the
channel layout editor.

3. The currently active layout has a red button in the right-most column.
4. Touch the empty circle for another layout to make it the active layout; the layout changes in the live
stream (and recording), and the new row gets the red button.
5. Continue to switch layouts as needed for the duration of your event or recording.
Switching / mixing using Epiphan Live
Epiphan Live is a simple and easy to use interface which is used for confidence monitoring,
streaming/recording control and live switching. (See Epiphan Live for more information.)
Within Epiphan Live, the Switcher view allows you to seamlessly switch between a channel's custom layouts
while live streaming and/or recording.
To switch a layout while live streaming and/or recording using Epiphan Live:
1. Log in to Epiphan Live; the Dashboard view opens by default. See Accessing Epiphan Live.
2. Click the Menu icon in the upper-right corner of the Dashboard screen and click Switcher to navigate
to the Switcher interface.

selectable.
After selecting your channel from the dropdown, the Switcher interface appears with all of your

What is a source?
What is a source?
A source can be an image, video, or audio from a camera, a computer screen or any device that provides a
VGA, S-Video, SDI, DVI or HDMI video signal and audio signal output.
You can also connect RTSP sources such as IP cameras to your VGADVI Recorder Pro over a network using the
Admin panel. See Connect an RTSP source.
Video sources
The Admin panel automatically discovers all video source ports and displays them in the Sources section of
the Admin panel. RTSP sources need to be added manually to display in the Sources section (see Connect an
RTSP source). When an RTSP source is added, a corresponding audio sources is always added to your custom
layout editor (regardless of whether or not the RTSP stream actually contains any audio). See Add an audio
source (custom channel).
Video sources are also displayed on the Epiphan Live control interface. See Monitoring
video and audio sources for more information.
Each video input on the back of the system is a frame grabber. Input sources are identified by their frame
grabber serial number. Each frame grabber has one DVI port, one SDI port, one S-Video port, and one audio
port. DVI ports are listed with the suffix .vga, SDI ports with the suffix .sdi, S-Video inputs are listed with the
suffix .video, and audio inputs are identified by the word audio. Video sources include a preview of the images
they are capturing. It is a good practice to view the images from each source to confirm what is captured. See
below.
When a source is connected, the system automatically detects and adjusts the image capture settings at start
up and continues to adjust every 60 seconds during operation (interval is configurable). The system’s goal is to
produce the best quality captured image given the source equipment used. Generally no further
configuration is needed.
If there is no source connected to a specific port or no input stream being transmitted from a connected RTSP
source, then the default "No Signal" image will display in any channel where the source is used. You can use
VGADVI Recorder Pro.'s default "No Signal" image for your sources, or you can create your own custom "No
Signal" image for your channels to enhance branding and add professionalism to your display. See Add a No
Signal image to a source .
155
VGADVI Recorder Pro User Guide
What is a source?
Audio sources
VGADVI Recorder Pro's Admin panel also automatically discovers all audio sources displays them in the same
section, with the exception of RTSP audio sources. When an RTSP input stream is connected to your VGADVI
Recorder Pro, a corresponding audio source is automatically added to the list of audio sources for your
channels, even if there is no audio in the RTSP stream (see Add an audio source (custom channel) for more
information).
Audio input devices such as a microphone and portable music players can send audio signals to the VGADVI
Recorder Pro using the audio input ports at the back of the system. Audio is also supported via HDMI and
SDI.
DVI2PCIe cards do not support audio over HDMI. VGADVI Recorder Pro systems with DVI2PCIe
cards will not be able to capture audio through HDMI sources.

Connect a source
Connect a source
You can physically connect composite or S-video, SDI, VGA, HDMI or DVI sources to the VGADVI Recorder Pro
at any time, either before or after the system is powered on. Similarly you can disconnect a source from a port
and even connect a different source at any time.
You can also connect wireless RTSP sources to your VGADVI Recorder Pro over a network. Both the RTSP
source device and your VGADVI Recorder Pro need to be powered on to establish a connection. See Connect
an RTSP source for more information.
Changing the source that is being streamed or recorded can result in the recording stopping or the
stream frame size changing depending on how your channel is configured.
If the frame size changes, viewers may be disconnected and need to re-connect to the stream.
Connect sources to the following input ports on your system:

VGADVI Recorder Pro User
Guide
Connect an RTSP source
Decoding a 1080p RTSP signal at 30 fps consumes approximately 10% of your VGADVI
Recorder Pro's CPU power. If an RTSP source is connected but unused in any channel,
VGADVI Recorder Pro decodes only key frames to preserve CPU resources.
To synchronize timestamps between your RTSP source and your VGADVI Recorder Pro, the same time
synchronization server should be used for both devices. It is recommended that you configure an NTP server
on your VGADVI Recorder Pro and use VGADVI Recorder Pro as a time synchronization server for your RTSP
source. See Configure synchronized time (NTP, PTP v1 and RDATE).
Due to the nature of external encoding devices such as RTSP sources, it is possible for the timestamps
between your VGADVI Recorder Pro and your RTSP source to gradually become out of sync. If there is a 2500
–3000 ms timestamp difference between your RTSP source and your VGADVI Recorder Pro, then a "no signal"
image will display and your RTSP source will not stream any audio. Re-connecting your RTSP source resets any
time synchronization issues.
To connect an RTSP source to your VGADVI Recorder Pro:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Under the Source header, click Add source to open the IP sources page.
3. Click Add RTSP source to open the source configuration page.

RTSP sources
RTSP sources are configured for connection to your VGADVI Recorder Pro using the Source URL, Username
and Password specific to your selected RTSP source. (See Connect an RTSP source for more information).
RTSP sources can be further configured with a Preferred transport protocol (either UDP or TCP) and a
custom "No signal" image. (See Add a No Signal image to a source ).
Add a No Signal image to a source
By default the system displays a gray background with the text No Signal when there is no video signal coming
in to a source. You can customize this image to display a different message to your viewers. For example if a
viewer logs in early, or if you are experiencing delays you could indicate the start time (or expected resolution
time) using the no signal image.
Before you can specify a custom no signal image for a source, you must upload it following the procedure To
upload an image.
Transparent PNGs are not a supported file type for "No Signal" images.
To set the no signal image for a source:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
3. Follow the instructions above (To upload a logo to a channel) to upload an image via the Branding
Content page.
4. From the Admin panel, select your desired source under the Source header; the source configuration
page opens.

5. Select a “No signal” image. This image displays in the channel when the source's signal is not detected.
(If your uploaded image does not appear in the list, ensure it doesn't exceed the maximum file size of
3840×2160.)
Alternatively, to select an image you can simply drag and drop your chosen picture file to the blank
space below the Image field.
6. In the Timeout field, enter the number of seconds before the "No signal" image is displayed. If no
manual value is entered, the default time to display is 5 seconds.
7. Click Apply.
8. Test that the No Signal image is correctly applied by disconnecting your source and previewing the
channel(s) containing said source. See Preview a channel for more information.
Rename a source
Source names are used when adding sources to channels, therefore it is important that you know the name of
the source you wish to use. If a channel has only one source, the channel name will by default be the same as
its source name and will update automatically when the source name changes.
Sometimes it's helpful to configure the source name to match the data it's capturing so it's clear what the
channel is capturing too. Alternately you can change the channel's name. See Rename a channel.

Troubleshoot capture
Troubleshoot capture
In addition to fine tuning channel settings such as frame rate, resolution and bit rate to ensure optimal use of
resources while streaming a quality video, there may be circumstance when you must fine tune the video
input source.
Changing how source images are displayed may cause undesired results, for example
experimenting with the PLL setting may result in the image not being displayed properly. It is a
good practice to backup your configuration settings so that you can revert back to a good
configuration if the changes that you made are not desirable. See Configuration presets.
The following topics are covered in this section:
l Remove black bars (matte) from the video
l Force the capture card to use a specific EDID
l Unstretch the output video
l Video not centered (VGA sources only)
l Remove the combing effect on images
l Video looks squished (VGA sources only)
l Video too bright, too dark or washed out (VGA sources only)
Remove black bars (matte) from the video
By default, for channels with only one layout and only one source, the VGADVI Recorder Pro makes sure that
the aspect ratio of input signals is preserved when the output is streamed. If an input video signal doesn't
match the encoded frame aspect ratio, bars are added to the sides or top and bottom of the encoded stream
when the output is streamed and recorded. The color of the bars (matte) is defined by the Background color
selected on the Channel sources page. See Create a custom channel.
For example:
l Input signal resolution is 720×480 (a 3:2 aspect ratio)
l encoded resolution is 640×480 (a 4:3 aspect ratio that is narrower than the input resolution)
Borders are added to the top and bottom of the image to preserve the wider ratio of the input.

Remove black bars (matte) from the video
For example:
l Input signal resolution is 720×480 (a 3:2 aspect ratio)
l encoded resolution is 1280×800 (a 16:10 aspect ratio that is wider than the input resolution)
Borders are added to the left and right of the image to preserve the narrower ratio of the input.
If you are seeing bars on your image but would rather have the image fill the whole screen you have to

Match the output frame size to the aspect ratio of the source
signal
The frame size is matched only for layouts that have only one source. Note that if you have
layouts with different frame sizes, switching them while live streaming will cause an interruption
and restart of the stream. The same thing happens if you change the resolution of your source
while streaming.
To change the output frame size on channels to match the aspect ratio of the source:
1. Connect to the Admin panel using your preferred connection mechanism. See Connect to the Admin
panel.
2. Login as admin.
3. Select a channel; the menu expands.
4. Click Sources; the Sources page opens.
5. Find the name of the media source used for the channel.
6. Click this source under the Sources menu.
7. Make note of the input signal resolution.
8. Click the channel's Encoding; the Encoding page opens.
9. Scroll to the frame size parameter.
10. The simplest option is to select Use current signal resolution as frame size and click Apply. You can
alternatively select it briefly to note the current video signal resolution, then deselect it and follow the

Force the capture card to use a specific EDID
Extended display identification data (EDID) is data provided by a video display device (usually a monitor) to
describe its capabilities to a video source (usually a graphics or video output card in a PC or another device).
The video source uses the EDID to determine the capabilities of the monitor to determine the resolution, color
depth and other settings that the monitor can support.
EDID is crucial for DVI sources but mostly ignored by VGA sources.
175
VGADVI Recorder Pro User
Guide
Force the capture card to use a specific EDID
Like monitors, each video capture card in theVGADVI Recorder Pro contains an EDID. When you connect a
VGA or DVI video source (such as a laptop or video camera), this source sees the VGADVI Recorder Pro's HD
Encoder's capture card as a monitor and uses its EDID to negotiate which video signal to send.
Generally the capture card's DVI input correctly emulates a monitor that supports your video source.
However sometimes, particularly if your source uses a custom set of display properties, you need to help
VGADVI Recorder Pro's HD Encoder by uploading a custom EDID to force the capture card to report that it
emulates a resolution, color depth, etc needed by your laptop, camera or other video source.
Upload a new EDID
In most circumstances the factory installed default EDID, is sufficient. However, there may be some cases
where a video source uses resolutions that you do not want to use. In that case you can choose an EDID that
forces the VGADVI Recorder Pro's capture card to use a specific set of attributes.
The uploaded EDID is permanently installed on your system and this capture card (a "Source" in the Admin
panel) will always share the uploaded EDID with the connected video input source.
EDID changes are permanent until you replace them with another EDID or specifically choose to
restore the facotry EDID for a given source. Not even a system-level factory reset removes the
configured EDIDs.
1. To download a new EDID file, go to the Epiphan support web page. The support page opens.
2. Select the support page for VGADVI Recorder Pro.
3. Scroll to the EDID section.
4. Click on an EDID from the list. The file is saved to your downloads folder on your hard drive.
5. Connect to the Admin panel using your preferred connection mechanism. See Connect to the Admin
panel.
6. Login as admin.
7. From the Admin panel, Scroll to the Sources section.

Restore factory default EDID
When you have finished with a custom EDID, you can restore the capture card (in the Sources list) to the
default EDID. Currently there is no way to tell if your capture card is using a custom EDID. If you are unsure,
restoring to factory default is the best approach.
To restore the default EDID:.
1. Login to the Admin panel as admin. See Connect to the Admin panel.
3. From the Admin panel, scroll to the Sources section.

Unstretch the output video
Unstretch the output video
By default, the VGADVI Recorder Pro makes sure that the aspect ratio of input signals is preserved when the
output is streamed. If this default was overridden or if the channel was created in a version of the software
earlier than 3.11.0, the image is stretched to match the output frame size. The effect may be subtle and may
not be problematic for you, but if you want to resolve this it is very simple to do.
To preserve the source aspect ratio:
1. Connect to the Admin panel using your preferred connection mechanism. See Connect to the Admin
panel.
2. Login as admin.
3. From the Admin panel, click Encoding; the encoding page opens.
4. Click Sources; the Sources page opens.

Video too bright, too dark or washed out (VGA sources only)
If the video from the source is too light, too dark or washed out, use the offset and gain controls together to
optimize image quality. Increasing the gain amplifies weak signals but also increases noise, you must balance
offset and gain values to achieve the best quality image.
Adjust these settings by the smallest values possible; compensate for a large change to one by making a large
change to the other. Setting both offset and gain to high values can result in poor video quality.

can view the broadcast.
To restrict access by IP address you need to know the IP addresses, or range of addresses for your viewers. By
default all IP addresses are allowed to connect to the broadcast.
If you’re not familiar with creating allow/deny lists, refer to the examples below this procedure for assistance
with crafting your lists.
To restrict viewers by IP address:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Select the Access passwords link in the Configuration menu; the password configuration page opens.
3. Type allowed IP addresses or address ranges in the Allow IP’s field. Separate addresses with a comma.
4. Type denied IP addresses or address ranges in the Deny IP’s field. Separate addresses with a comma.
5. Click Apply.
To restrict viewers of a specific channel by IP address:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Select the Streaming link for the desired channel; the streaming configuration page opens.
3. From the Access Control drop-down, select Use these Settings; local password and Allow/Deny IP
lists are enabled.
4. If desired, type a password for the viewer in the Viewer Password field.
5. Type allowed IP addresses or address ranges in the Allow IP’s field. Separate addresses with a comma.
6. Type denied IP addresses or address ranges in the Deny IP’s field. Separate addresses with a comma.
7. Click Apply.
If a user attempts to connect to the stream from a disallowed IP address, access is denied. If connecting by
internet browser, the message "IP address rejected." is displayed.
The following table describes the applicable fields.

Description/Options
Enter individual IP Addresses or IP Address ranges, separated by commas. To specify a
range, use a hyphen (-). Optional spaces improve readability.
Users connecting from addresses in this list are permitted to view broadcasts from the
Allow IP's
system, provided their IP address is not in the Deny IP’s list.
To allow all (except IP addresses in the deny list, if any), leave the field blank.
You can use the Allow list by itself, or in conjunction with the Deny IP’s list as an exception
to a rule in the allow list.
Enter individual IP Addresses or IP Address ranges, separated by commas. To specify a
range, use a hyphen (-). Optional spaces improve readability.
Users connecting from addresses in this list are not allowed to view broadcasts from the
Deny IP's
system, unless their IP address is in the Allow IP’s list. If a specific IP address is in both lists,
access to the stream is denied.
You can use the Deny list by itself, or in conjunction with the Allow IP’s list as an exception
to a rule in the allow list.
IP restriction examples
Allow list with distinct IP addresses
The simplest allow/deny list is to use the list of known IP addresses to craft a list of allowed IP addresses. All
other addresses are denied access to the broadcast.
For example if your system is accessible on your local area network (LAN) and you want to make sure only the
CEO’s specific desktop, laptop and tablet computers (with IP Addresses 192.168.1.50, 192.168.1.51, and
192.165.1.75, respectively) can connect to the broadcast, construct the following allow list:
Allow: 192.168.1.50, 192.168.1.51, 192.168.1.75
Allow list with a range of IP addresses
Sometimes you’ll want a range of computer IP addresses to connect to your system. This may happen when
you have one range of IP addresses assigned to desktop computers (i.e. in the range 192.168.1.1 to
192.168.1.100) and another range assigned to boardroom computers (i.e. the range 192.168.1.200 to
201
VGADVI Recorder Pro User Guide
IP restriction examples
192.168.1.250). If you only want the boardroom computers to connect to broadcasts from the system you
can specify the range of boardroom IP addresses rather than needing to type in each individual address. The
allow list looks as follows:
Allow: 192.168.1.200-192.168.1.250
Note that we could have specified two of the IP addresses in the previous example as a range.
Allow list with a range of IP addresses and one or more specific IP
addresses
Putting the first two examples together, we want to permit access to IP addresses in the range of boardroom
computers (192.168.1.200-192.168.1.250) and also want to add the desktop, laptop and tablet computers
of the CEO (IP addresses 192.168.1.50, 192.168.1.51, and 192.168.1.75, respectively). Note the first two IP
addresses are consecutive, so they can be added as a second range. Add these IP addresses to the list as
follows:
Allow: 192.168.1.200-192.168.1.250, 192.168.1.50-192.168.1.51, 192.168.1.75
Your list can have multiple ranges and multiple distinct IP addresses, provided they are separated by commas.
Deny list with distinct IP addresses
Another simple allow/deny list is to use the list of known IP addresses to list specific denied IP addresses. All
other addresses are allowed access to the broadcast.
For example imagine your system is accessible on your local area network (LAN) and you want to allow any
computer on the LAN can access the stream except your publicly-accessible boardroom (with IP address
192.168.1.211). You can use the following deny list (leave the allow list empty) to permit all computers except
the boardroom computer:
Deny: 192.168.1.211
As with allow lists, your deny list can specify a range of IP addresses, and can specify multiple ranges or distinct
IP addresses in a comma-separated list.
202
VGADVI Recorder Pro User Guide
IP restriction examples
Allow list with a range of IP addresses, distinct IP addresses and an
exception
Building on the previous examples, consider the situation where you want the CEO’s computers
(192.168.1.50, 192.168.1.51, 192.168.75) and all boardroom computers (192.168.1.200-192.168.1.250)
to access the broadcast, with the exception of the public boardroom computer (192.168.1.211). Use both
allow and deny lists to create the rule as follows:
Allow: 192.168.1.200-192.168.1.250, 192.168.1.50-192.168.1.51, 192.168.1.75
Deny: 192.168.1.211
Both lists can have multiple ranges and multiple distinct IP addresses, provided they are separated by
commas.
Deny list with a range of IP addresses
Converse to the previous examples, consider the situation where you want every computer on the network to
access the broadcast, with the exception of the CEO’s desktop, laptop and tablet computers. Additionally,
boardroom computers should not be permitted with the exception of the cafeteria computer (IP address
192.168.1.222).
The deny list is an "exception" list for the allow list. So to craft the rule described above we need to allow all the
computers in the local subnet, then deny specific sub-ranges including two groups of boardroom computers
ensuring the cafeteria computer's IP address is not in the deny list:
Allow: 192.168.1.1-192.168.1.250
Deny: 192.168.1.200-192.168.1.221, 192.168.1.223-192.168.1.250, 192.168.1.50-192.168.1.51,
192.168.1.75

Stream to a server
Stream to a server
Your VGADVI Recorder Pro streams to a server when you want to use a CDN or Multicast. .
By default, no server streaming is configured. See Stream to a CDN and Stream content using multicast for
details on configuring one of these two options.
Publishing Options
Use this option to...
Stream web content to many viewers simultaneously to any geographical
location. A viewer accesses the broadcast from a website using a user name
and password, if required. Using a CDN to host your broadcast is highly
scalable and makes financial sense to website owners since you do not pay
for additional server hardware or routing should your network traffic
increase or decrease.
Content Distribution
Network
Using a CDN to stream live content allows you to reach a large
geographically diverse audience and because CDNs perform format
conversion, the stream is platform independent.
You can control when streaming to a CDN is enabled by using the Admin
panel. See Start and stop streaming to a CDN.
For more information about streaming to a CDN, see Stream to a CDN.
Stream content to a multicast IP address where it can be shared with
multiple viewers within the same LAN. All viewers receive the same stream
at the same time. Similar to turning on a radio station where all listeners
hear the same music at the same time.
This delivery method relies on network equipment that supports
multicasting and is usually used in high bandwidth corporate LANs and not
Multicast Streaming
on Internet-based architectures.
This delivery method is useful for training sessions, when there is a specific
timeframe when the audience will view the content. For more information
about using multicasting for streaming your content, see: Stream content

Stream to a CDN
To stream video outside of your LAN, use a CDN or configure port forwarding on your router.
Refer to your Network Administrator; network configuration is beyond the scope of this guide.
Streaming to CDNs and multicast streaming is available only when the H.264 codec is selected.
Stream to a CDN
A Content Delivery Network (CDN) relies on geo-diverse CDN servers to receive and disperse web content to
the CDN server closest to the user. The closer the server is to the user the faster the content is delivered.
Streaming your content through a CDN allows you to stream any time, anywhere, regardless of the viewing
device.
You can publish to any CDN provider that supports incoming streams sent via RTSP announce or RTMP push.
Both RTSP and RTMP can be used for live streaming, however not all CDNs or media servers support both
formats. Choose the streaming format that your CDN or media server supports. Epiphan has tested with the
CDN providers listed here: http://www.epiphan.com/partners/cdn-partners/. Contact your CDN for a list of
supported audio codecs and ensure your configuration uses one of the supported codecs.
To publish content to a CDN provider ensure you have:
l a path to the mount point or an XML configuration file (provided by the CDN provider);
l verify which transport protocols your CDN supports:
l a current flash player; and
l select the H.264 codec from the channel's Encoding page.
You can control when streaming to a CDN is enabled by using the Admin panel. See Start and stop streaming
to a CDN.

Stream content using multicast
A multicast stream consists of one stream distributed to many viewers via a multicast-capable network.
VGADVI Recorder Pro supports multicast streaming content to an IP TV or a set-top box playlist when the
stream format is MPEG-TS.
The following procedures outline the steps to distribute your content using multicast streaming:
l MPEG-TS streams using RTP/UDP push
l MPEG-TS streams using UDP push
l Multicast streaming using RTP/UDP
MPEG-TS streams using RTP/UDP push
Before configuring your channel for MPEG-TS streaming, ensure the following codecs are configured:
l Video – H.264
l Audio – MP3 or AAC, if audio is configured.
To configure your channel for MPEG-TS using RTP/UDP push:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
3. From the Admin panel, click a Channel; the menu expands.
4. Click Streaming; the channel's Streaming page opens.
5. Click the Publish drop-down menu.
6. Choose using MPEG-TS RTP/UDP push.
7. Enter the destination multicast IP address where the broadcast can be viewed.
A IPv4 multicast address range is an address between 224.0.0.0 to 239.255.255.255.
Contact your System Administrator for the specific address to use.
8. Enter the destination port number through which the media will stream.

VGADVI Recorder Pro User Guide
Stream content using multicast
10. Enable the SAP announcement checkbox to advertise your stream over a local network. When the
checkbox is enabled and a multicast IP address is configured, your stream is displayed in the playlist of
local media player.
11. Enter a multicast IP address in the SAP announcement IP field. If your media player is configured to
receive multicast streams from an IP address that is different from the default address 224.2.127.254,
you may need to contact your system administrator for a specific multicast IP address.
12. Enter a channel number in the Channel number field to identify your stream in the media player. By
default the Channel number is the channel identifier.
When a channel number value is not specified, viewers cannot select a channel from the
set-top box or Smart TV .
13. Enter a name for a group of streams in the text box next to Group name. Since media players simply
present a list of available streams, you can organize your streams into multiple folders or in cases where
folders are not displayed, use dot separator hierarchy to help your viewers filter out unwanted streams
by category.
14. Click Apply.
15. Click the Info menu option of the Admin panel. An Info page opens displaying stream information.
To view the stream from a media player, open the URL in a media player, for example:

Stream content using UPnP
Using the Universal Plug and Play (UPnP) networking protocol, your VGADVI Recorder Pro can be discovered
and can stream to software and hardware media players, set-top-boxes and Smart TVs with ease. If UPnP is
enabled, the system automatically establishes communication with media players on the network.
UPnP uses MPEG-TS over HTTP with the H.264 codec and MP3 or AAC audio encoding (or no audio). You can
only access live streams or recordings that meet these requirements.
For security reasons the default behavior prevents UPnP access to live streams and recorded files.
This section covers the following topics:
l Enable UPnP
l Disable UPnP
l Viewing with UPnP
l Play directly to a media player
l Auto-restart playback to a UPnP device
l Change UPnP device name
Some players will not be able to access the stream or saved recordings if a viewer password is set.
If needed, see User administration to clear the viewer password.
The topics in this chapter include how to enable and disable UPnP and how to control media players from the
VGADVI Recorder Pro. To choose recordings or live streams from your media player, see Play directly to a
media player.
Enable UPnP
Enable UPnP to allow digital media players on the network to browse for recorded media files or live streams
from your system. There are two steps required to enabled UPnP, enabling UPnP for the system (including
setting a share name) and enabling UPnP per channel or recorder. By default, UPnP is disabled at the
system level and for each channel.
Streams and MPEG-TS recorded files must use the supported codecs: H.264 with MP3 or AAC
audio. Having a viewer password could prevent the ability to use UPnP.

When choosing your stream settings it is important to consider the stream content. When streaming fast
moving video it's best to choose a higher bitrate and frame rate versus streaming a slide presentation where
you can save on bandwidth and system processing by lower the bitrate and frame rate. Stream setup is a
matter of balancing quality and system resource usage.

PART 4: Record
Your VGADVI Recorder Pro encodes the video and audio it captures. Not only can you stream this content,
but you can also simultaneously record it. In fact, if you're streaming a picture in picture layout or low quality
streams, you may even want to create separate channels to also record each input at full frame size and with a
high bitrate so you have the best possible digital media for future re-use or post-processing.
If you choose to record your channels, VGADVI Recorder Pro stores the recorded files on the system's amplysized hard drive and provides you a variety of automatic or manual mechanisms to download the files.
This section discusses the following topics related to recording:

What is a recording?
What is a recording?
Your VGADVI Recorder Pro can record the output from each channel. (See Recorders for information on
creating multi-track recorders using multiple channels.) Recordings are very robust and crafted so that even in
the case of accidental system shutdown, recording files are closed off and playable.
You can choose to record simultaneously while streaming, or record without streaming.
This section describes the following topics for creating and configuring recordings via the Admin panel.
• Recording basics
• Record a channel via the Admin panel
• Record a channel via Epiphan Live
• Record with a recorder
• Record a recorder (using Epiphan
Live)
• Configure recording file size and type
• Restart recording
• Control recording with a mouse
Recording control is easily performed through the Admin panel, but can also be set up for third party tools
using our APIs. See Control with HTTP commands and Control with RS-232 / serial port for information on
controlling recordings with third party tools.
See Recorded files to learn how to download the recorded files.
Recording can also be controlled via the Epiphan Live control interface. See Controlling
streaming and recording using Epiphan Live for more information.
Recording basics
While recording a channel or recorder, a new file is created each time the maximum time or size limit is met.
Additionally, when recording a multi-channel recorder or a multi-source layout channel, a new file is created if
an additional source is added to the recorder.
Physically removing the source (e.g. unplugging it) or otherwise interrupting the signal to the source does not
affect recording, and the recording will include the configured No Signal image.

progressive file format, and MP4-fragmented which is a more modern, fragmented format that isn't
supported by all video players or editors.)

Configure recording file size and type
Configure recording file size and type
By default, recorders and channels record to AVI files. When the recording reaches 30 minutes in length or a
file size of 500 MB (whichever occurs first), the system closes the current recording file and opens a new one.
This is done seamlessly with no loss in recorded data.
You may find it useful to have recordings divided this way for ease of download, but you may also want to
change the recording limits to be larger or smaller to meet your individual situation.

Recorders
Recorders
Your VGADVI Recorder Pro can record the output from each channel and, using Recorders, it can also record
multiple channels together in a single multi-track file.
Recording multiple channels at once ensures the recordings are started and stopped at the same time,
resulting in perfect synchronization. Once the recording is complete, you can automatically use one of the
system's file synchronization methods to copy it off the server, or you can use our built-in tool to split the file
into individual tracks for post-processing.
You only need to create recorders for multi-track recordings. For single channel recordings, see
Record a channel via the Admin panel.
This section describes the following topics for creating and managing multi-channel recorders.
l Add a recorder
l Change the channels recorded by a recorder
l Record with a recorder
l Record a recorder (using Epiphan Live)
l Rename a recorder
l Delete a recorder
See What is a recording? to learn how to create recordings and configure recording file sizes.
If you upgraded from a previous firmware release that included an all-in-one recorder, your all-inone recorder is now listed under the Recorders section of the Admin panel. Your recordings are
preserved and any URLs used to access the all-in-one recorder previously through the HTTP API
correctly map to the new location.
Add a recorder
Each channel has its own built-in recorder that is accessible from the Recording link. If you want to record
several channels simultaneously to a multi-track file, create a new recorder.

Recorded files
Recordings you make of channels or with recorders are stored on the system's internal hard drive. The
VGADVI Recorder Pro has a finite amount of available hard drive storage space. Though it is enough space to
hold a lot of recordings, it will eventually run out of space if recordings are added but never removed. When
this happens, the system deletes the oldest recorded files to make room for new recordings.
You can use a variety of methods to automatically transfer files from the system to local network storage.
Alternatively you can manually select individual recordings to transfer or delete.

Choose files to include in AFU
The following types of off-system storage are supported for AFU: FTP, CIFS, RSync, SFTP, SCP and
USB Drive.
Only one type of AFU can be used at once.
Files are uploaded once (i.e. are automatically not re-uploaded during future sessions) and a log is kept
showing the file transfers (see below for details on viewing the log). The first transfer occurs after the
configured amount of time expires or after the current file completes recording. If connection is lost during
the transfer, the transfer is automatically restarted when the connection is reestablished.
By default, channels and recorders are not configured to support automatic file upload for their recorded
files. You must enable this feature for each channel or recorder you wish to include in your automatic file
transfers.
If recorded files are selected for upload while the AFU is at maximum upload capacity or when the AFU is
unavailable, they are added to an upload queue. Files and their relevant information are displayed in a list
format, and each file will be uploaded when upload capacity becomes available.
Choose files to include in AFU
When configuring automatic file upload (AFU) you need to tell the system which channels and recorders you
want included in the upload schedule.
When you log into the system and attempt to configure your desired type of AFU you see the following
warning in the Automatic File Upload configuration page if no channels or recorders are configured to be part

AFU or copy to USB drive
The system is equipped with USB ports that can be used to copy files from internal storage to external USB
flash drives or hard drives. An example use of this feature is to provide speakers with a copy of their
presentation before they leave the presentation venue.
The external drive must be formatted with one of the following file systems:
l FAT16
l FAT32
l XFS
l EXT2
l EXT3
l EXT4
l NTFS
Only the first attached USB drive is used for automatic file upload. If more than one USB drive is
attached before system power up, behavior is unpredictable.
File transfer to a USB drive occurs in one of the following ways. This section describes the procedures.
l AFU to a USB drive
l One-time copy/move of all recorded files to USB drive
l Manually copy recorded files to USB drive
l View available USB storage space

Channel folders are labeled video<channel number> (i.e. video3 for channel 3). Recorder folders are labeled
videom<recorder number> (i.e. videom1 for the first recorder). Channel and recorder numbers are displayed
next to the name of the channel or sources in the Admin panel.
To get started you will need:
l The IP address of your system (found in the Network configuration menu)
l An FTP tool
l The username and password for your FTP user (See Configure the local FTP server)
In the example below, the IP address of the VGADVI Recorder Pro is 192.168.1.210, the username is admin,
there is no password, and the Windows command line ftp utility is used.
To connect to the FTP server:
1. Open a command window on Windows (alternatively open a terminal window on Linux/Mac, or open
your FTP utility of choice).
2. Establish an ftp connection using the command: ftp 192.168.1.210.

The previously used backup and restore procedure is replaced by configuration presets, which are the perfect
way to backup all or any set of your configuration items for future import back to the same system or
another. See Configuration presets for more details.
After completing configuration of your VGADVI Recorder Pro, it is good practice to save the system
configuration so you may restore it at a later date (i.e. after a change that wasn’t wanted, or after a factory
reset). In addition to full configuration backups, you can also save and restore configuration preset groups see Configuration presets for details about that feature.
This section covers the following topics:
l Save device configuration
l Load a saved device configuration
Save device configuration
VGADVI Recorder Pro's Admin panel allows you to save the current system configuration to your admin
computer's hard drive. It’s good practice to do this before making any major changes to a working
configuration and before doing a firmware update.
The resulting backup file includes all non-default configuration settings for the system, except the
user passwords which are reset when a configuration is restored.
Configuration backup files are only guaranteed to work with the same firmware version with
which they were created. Normally there is no issue loading an older configuration file on a newer
release, but the reverse is not true and there are exceptions where older configuration files are
not supported in a new release.
To save the current system configuration:

Configure remote support
Remote support is configured by default to connect to the Epiphan maintenance server with the domain
name epiphany.epiphan.com. The system must be able to resolve this domain name to connect to the server
and permit remote support. Remote support uses ports 22 and 30, therefore this port must be available for
communication. If your system is protected from the Internet by a firewall, speak to your network
administrator to configure the firewall appropriately.
Remote support is available from Epiphan only if your device is covered by SupportPlan+.
To configure remote support:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Select the Maintenance link in the Configuration menu; the maintenance page opens.

Storage disk maintenance
Storage disk maintenance
Your VGADVI Recorder Pro is equipped with one or more hard drives for storage of recordings. Occasionally,
maintenance is required for these disks. This section describes procedures for the following topics:
l Check disk storage space
l Schedule disk check
l Perform disk check
l Rebuild or replace storage disks
l Verify RAID storage
l Read data from removed storage disks
Check disk storage space
VGADVI Recorder Pro has a finite amount of storage This storage space holds a lot of recordings, but it can get
full. It’s a good idea to monitor your current disk usage.
If available storage is low, consider removing some unneeded recordings or setting up an automatic file
transfer with deletion after transfer. See Recorded files and File and recording transfer.
Disk space can also be checked via the Epiphan Live control interface. See Configuring
Dashboard panels for visual confidence monitoring for more information.
To check disk storage space:
1. Login to the Admin panel as admin or operator. See Connect to the Admin panel.
2. Check the Internal Storage section at the bottom of the menu column. The bar will be mostly green if
there is lots of space left, or mostly red if storage space is nearly full.
3. If available storage is low, take action to remove files as discussed in Recorded files and File and
recording transfer.

Schedule disk check
Schedule disk check
A disk maintenance schedule is used to check the system storage drives for errors. Two values are supplied,
one to specify the number of system restarts that should occur before disk check, and the second to specify
the number of months before performing a disk check. The disk check happens based on whichever event
occurs first.
For example, let's say the restart setting is set to 50 and the months setting is set to 6. If six months pass and
less than 50 restarts happened, a disk check will occur on the next restart. However if you do 50 restarts in
one month, the disk check will happen after the fiftieth restart.
Disk check occurs during start up and can cause a lengthy delay in starting up the system.
To set the disk check schedule:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Select the Disk Check link in the Configuration menu; the disk maintenance page opens.
3. Set the number of restarts to occur before the next check. Set to 0 if you don’t want to force a
disk check after a specific number of restarts.
4. Set the number of months to pass before the next check. Set to 0 if you don’t want to force a
disk check after a specific number of months.
5. Click Save.
Perform disk check
A disk maintenance schedule is used to periodically check the system storage drives for errors. If you prefer,
you can run the disk check manually at a time that is convenient for you.
Running the disk check manually resets the timers for the scheduled disk check (i.e. next check won’t happen
automatically until either the number of restarts or months passes).
If the system is recording when you start a disk check, it will stop recording and resume after the
check is complete. Frames presented during the disk check are not part of any recording.
To start a manual disk check:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Select the Disk Check link in the Configuration menu; the disk maintenance page opens.
3. Click the Check Now button; a new page opens showing you the progress of the disk check.

5. If any unrecoverable errors are detected, contact Epiphan support.
Rebuild or replace storage disks
The rackmount VGADVI Recorder Pro can be optionally configured with storage configured in a RAID array.
Periodically you may wish to clean the RAID array to start from scratch, or you may want to introduce new
disks in place of the old ones.
When working with RAID arrays it is important to keep the disks in sets that contain the same data so the
RAID will continue to perform. For that reason you should name your disk sets, i.e. set A, set B, etc.
If you need to revert from a multiple-disk RAID array to a single storage drive, all recordings must
be copied off VGADVI Recorder Pro and the other drive need to be completely removed from the
system. The system must then be rebooted before a "build disk" is performed on the remaining
drive.

Rebuild or replace storage disks
When purchasing a new disk set, ensure that the drives in the new set are identical (brand, size, and type).
To change the disk set:
1. Power down the VGADVI Recorder Pro.
2. Open the front panel of the system (the panel key may be required).
3. Remove the old drives, starting with the second drive from the left, moving to the right.
Do not remove the left-most drive. This is the system drive and is not swappable.
4. Seat the replacement drive set into the drive bays.
5. Power on the system.
6. Follow the steps below to rebuild the storage disks.
See Read data from removed storage disks for information on reading data from the removed drives.
Rebuilding the storage disk set is a destructive process that erases everything from the disks.
Proceed with caution.
To rebuild the storage disks (erasing all data):
1. Login to the Admin panel as admin. See Connect to the Admin panel.
1. Select the Disk Check link in the Configuration menu; the disk maintenance page opens.
2. Scroll to the bottom of the page to the Internal Storage section:
a. If no RAID drives are detected, you do not have a storage RAID, but you can rebuild the current
drive, deleting all saved recordings.
b. If two or more drives are detected, you are prompted to select a type of RAID array.

Read data from removed storage disks
If using multiple drives and one of the drives fails or is removed, then the RAID needs to be
rebuilt. The files stored on the remaining drive(s) will need to be downloaded via Admin panel,
AFU or FTP prior to RAID rebuild.
These steps describe how to read the recorded files from the removable storage drives using Ubuntu.
Depending on your exact version of Linux, the steps you follow may differ slightly from the steps
below.
To read the recorded files:
1. Install Linux on a workstation where the drives will be installed (Ubuntu or Debian are recommended.
RedHat/CentOS/Fedora are also supported).
2. Confirm mdadm tool is installed, if not, install it. For Ubuntu/Debian use apt-get, for RH/CentOS use
yum.
3. Turn off the workstation and connect the storage drives (if using RAID 1 you can attach just one drive).
4. Start the workstation.
5. If only one drive of a RAID 1 set is connected:
a. Open a terminal window and enter the following in the command line to determine the name of
the disk:
sudo fdisk -l
b. Issue this command to build the disk:
(In the example, the disk name is /dev/sbd1. Your disk name may be different.)
sudo mdadm —assemble /dev/md0 /dev/sdb1
c. The following message appears:
mdadm: /dev/md0 has been started with 1 drive (out of 2).
6. Verify that RAID is started. At the command line, enter:
sudo mdadm -D /dev/md0

9. If using a graphical interface in Linux, browse to the location of the drive in File Manager. Otherwise,
use a terminal window to change directories (cd) into the drive.
10. Browse to the /mnt/raid folder (or the appropriate folder name) in File Manager.
11. All recordings are kept in a folder hierarchy matching the channels and recorders you created via the
Admin panel. Channels are listed by their channel number as video<channel number> (i.e. video1 for
channel 1) and recorders are listed by their recorder number with the videom prefix (i.e. videom2 for
recorder 2).

Control with RS-232 / serial port
VGADVI Recorder Pro presents an RS-232 / serial port control interface for integration with existing control
room and board room equipment. This section covers the following topics:
l Connect and configure the RS-232 cable
l Control the VGADVI Recorder Pro with RS-232
l RS-232 / Serial port command examples
Connect and configure the RS-232 cable
To connect your control equipment to the VGADVI Recorder Pro you will need a standard RS-232 null-modem
cable and a USB to RS-232 serial adapter cable. Adapter cables are not included with the VGADVI Recorder
Pro. Only certain adapter chipsets are supported, Epiphan recommends this adapter cable from Startech.
To connect the serial port cable:
1. Attach the null modem cable to the control interface.
2. Connect the null modem cable to the serial port on the back of the system.
The only configuration available for the serial port is flow control. Flow control changes the rate of data
transfer over the cable. Some communication settings are static and cannot be changed. The static settings
are:
l Baud rate set at 19200
l Parity set to none
l Stop bits set to one
To configure serial port flow control:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Select the Serial Port link in the Configuration menu; the serial port configuration page opens.
3. Select Hardware, Software, or None from the drop-down menu. Refer to the table below for a

Control the VGADVI Recorder Pro with RS-232
You can use the null-modem cable and your control terminal software to issue commands to the VGADVI
Recorder Pro such as when to start or stop recording, or to retrieve or set the value for various settings.
Each command sent to the VGADVI Recorder Pro via RS 232 must be terminated with a line feed (LF) character (ASCII code 10). Your software may need to be configured to add the line feed to
each command.
Some commands require a channel or recorder name as an argument. In those commands, the channel or
recorder name is separated from the command name by a period, as shown in the table. The channel name
value can be either the name or the index of the recorder or channel. Use of the index is recommended.
A channel's index is found by looking at the Channels list in the Admin panel. In the screen capture below, the
channel with index 1 is currently recording (it's index number is red). To address this channel via RS-232
commands, use the index 1.
For commands requiring a recorder index, determine your recorder's index by combining the recorder's
number with the prefix m. In the example below, the second recorder's index is 2. To access this recorder via
RS-232 commands, use the index m2.

Control with HTTP commands
Control with HTTP commands
VGADVI Recorder Pro has an HTTP API interface for configuration and control by a third party application or
with a script that sends commands to the system as a series of URLs. This section covers the following topics:
l HTTP command syntax
l HTTP command examples
l Global variable HTTP command syntax for custom layouts
HTTP command syntax
Control of the VGADVI Recorder Pro by HTTP is done by sending commands to one of two URLs and
specifying the target configuration item. Syntax for the get and set commands follows.
Many commands require a channel or recorder index as an argument. A channel's index is found by looking at
the Channels list in the Admin panel. In the screen capture below, the channel with index 1 is currently
recording (it's index number is red). To address this channel via http commands, use the index channel1.
For commands requiring a recorder index, determine your recorder's index by combining the recorder's
number with the prefix channelm. In the example below, the second recorder's index is 2. To access this
recorder via http commands, use the index channelm2.

Control with HTTP commands
To Get configuration settings:
http://<address>/admin/channel<N>/get_params.cgi?key
(or for recorders, add 'm' before the recorder number, i.e. channelm1 for recorder 1)
http://<address>/admin/channelm<N>/get_params.cgi?key
To Set configuration settings:
http://<address>/admin/channel<N>/set_params.cgi?key=value
(or for recorders, add 'm' before the recorder number, i.e. channelm1 for recorder 1)
http://<address>/admin/channelm<N>/get_params.cgi?key
Where <address> is the IP address of the system, channel<N> is the channel number (i.e. channel2 for
channel number two), channelm2 for recorder two, key is the key for the configuration item being checked or
changed (see the list in Configuration keys for third party APIs ), and value is the value to set for the
configuration item.
Multiple requests at once
You can include multiple key/value pairs in a single command by separating the statements with &.
For example, the key for product name is product_name and the key for firmware version is firmware_
version. To send a request for both the product name and the firmware version, use the following command:
http://<address>/admin/channel1/get_params.cgi?product_name&firmware_version
Or, to turnoff publishing (set to 0) and set the bitrate (vbitrate) to 256,000:
http://<address>/admin/channel1/set_params.cgi?publish_type=0&vbitrate=256K
Third party applications like wget
If you’re using a third party application like wget to send commands to the system, always include the admin
username and password when viewing or setting configuration items.
The syntax for wget commands is shown below. Specify your system’s IP address, password and the key(s) or
value(s) you wish to query. Note your system may require use of single quotes around the password to
handle special characters such as exclamation marks.

For values with spaces, encode space as %20. i.e.: set_params.cgi?framesize=640%20x%20480
The examples assume a system IP address of 192.30.23.45 and admin password pass123.

Global variable HTTP command syntax for custom layouts
Your VGADVI Recorder Pro can create global variables via HTTP for use specifically with custom layout as
responsive text overlay elements. See Add a text overlay (custom channel) for more information on adding a
global variable into a custom layout.
Important considerations for global custom layout variables
l Each system variable must have its own unique name
l System variable names and variable values are case sensitive
l Each variable must start with a letter or underscore sign and is followed by any combination of letters,
digits and underscore characters [A-Za-z_0-9]{0,32} to a limit of 32 total characters (note that saving an
empty string to a variable will clear the variable value)
l There is a limit of 12 total unique system variables per VGADVI Recorder Pro system
l System variables can be used in text labels across any number of channels
l System variable commands can be issued at a frequency of 5 per second, and up to 6 variables may be
set in a single command (for example, variables "gpsvar1", "gpsvar2" and "gpsvar3" can be updated in a
single command, five times per second). After issuing a set command, all channels using the specified
variable(s) are updated. The frequency of commands issued is not influenced by the number of
channels on your VGADVI Recorder Pro system.
l System variables are considered volatile data and are erased when your VGADVI Recorder Pro system
reboots
Set variables – syntax and example
A set command saves a value to a variable, where <address> is the IP address of the VGADVI Recorder Pro,
name is the unique name for each variable, and value is the text/character content stored in each variable.
You can set multiple variables at the same time by separating each variable with an "&" (as shown within the
square brackets in the syntax below).
To "set" variables, use the following syntax:
334
VGADVI Recorder Pro User
Control with HTTP commands
Guide
http://<address>/admin/set_variables.cgi?name1=value1[&nameN=valueN]
For values with spaces, encode space as %20. (i.e.: set_variables.cgi?name1=640%20x%20480)
To erase a previously set variable, simply set the variable's name with an empty space.
Example: "http://192.168.0.129/admin/set_
variables.cgi?gpsvar1=N103%2068201%20W765%2029712&gpsvar2=S490%2018731%

Get variables – syntax and example
A get command returns the value of a variable (called name in the syntax). You can return multiple variables
at the same time by separating each variable with an "&" (as shown within the square brackets in the syntax
below).
To "get" a variable (or a list of specified variables), use the following syntax:
http://<address>/admin/get_variables.cgi?name1[&nameN]
Example: "http://192.168.0.129/admin/get_variables.cgi?gpsvar1"
returns:
"gpsvar1=N103 68201 W765 29712"
To "get" a list of all variables saved to your VGADVI Recorder Pro, use the following syntax:
http://<address>/admin/get_variables.cgi
Example: "http://192.168.0.129/admin/get_variables.cgi"
returns:
"gpsvar1=N103 68201 W765 29712

Configuration keys for third party APIs
Using HTTP or RS-232, you can send commands to the system to query or configure the system. For the RS232 and HTTP syntax see Control with RS-232 / serial port and Control with HTTP commands.
Using a "SET" command in RS-232 must always follow with the "SAVECFG" command for the new
configuration setting(s) to take effect.
When setting keys to values with spaces use the following syntax.
For RS-232:
Enclose in quotes: SET.2.framesize="640 x 480"
For HTTP:
Encode each space as %20: set_params.cgi?framesize=640%20x%20480

around these limitations.
Important notes about upgrading from firmwares older than 3.16.0
1. In release 3.16.0, configuration presets replaced the concept of backup files. These new files use a new format
to accommodate portability between systems. As a result, backup files from previous versions (prior to 3.16.0)
cannot be loaded on systems running firmware 3.16.0 or newer. Further, if upgrading from a release older than
3.16.0, all existing configuration presets are deleted during the firmware upgrade. Be sure to keep notes for
any configuration presets you wish to recreate.
2. As of release 3.16.0, streaming can be enabled and disabled independently from streaming credential
configuration. If upgrading from a release older than 3.16.0, streaming defaults to enabled (started) until set to
disabled.
Affecting encoding
l Limitation: When audio is enabled on an SDI source where video is already being captured, it takes up to 15
seconds for the system to detect the audio. Once detected, the audio is properly synchronized with the video.
Workaround: Start the SDI signal with audio enabled, or check to ensure audio is detected before streaming or
recording.
l Encoding with MPEG-4 sometimes results in poor quality.
Workaround: From the channel's stream setup, increase the video bitrate to improve picture quality.
l Video bitrate for MJPEG streams is larger than the configured value.
Workaround: Verify the actual bitrate on the channel's channel status page when there are connected viewers.
If lower bitrates are important, select another codec.
l For VGA sources only, some wide-mode resolutions are not correctly identified and result in a slightly squished
image (e.g. for a 1360x768 source, the detected resolution may be 1024x768).
Workaround: This issue is related to the video source. Test your source to see if it exhibits the issue. If
possible, avoid using wide-mode for VGA sources that exhibit this issue.
l The automatically calculated frame size for HD VGA sources is occasionally incorrect.
Workaround: This problem is caused due to cable degradation or poor cable connection. Re-seat or exchange
your VGA cable. If the problem is still not resolved, visit the Epiphan Pearl support page for a custom EDID to
resolve the issue.
l Audio is temporarily unavailable for up to 20 seconds while streaming and/or recording when the audio signal
parameters (e.g. sample rate) are changed.
Workaround: Refrain from changing audio parameters while streaming and/or recording. Any audio setting
changes must be completed while the stream/recording is stopped.
Affecting streaming and recording
l When switching layouts while streaming or recording it's possible to have a small number of frames
(approximately 100ms worth) repeated in the stream or recording file, and over the same time period a small
number of frames from the new layout skipped.
Workaround: If dropped frames are problematic for your application, avoid the layout switching feature.
l Streams and recordings at very low frame rates (e.g. 1 fps) are not playable in VLC media player.
Workaround: Use an alternative media player, such as Windows Media Player and Quicktime Player.
Affecting the Admin panel
l It is possible to name two or more channels with the same value. Use of automatic file transfer and UPnP is
unpredictable if this occurs.
Workaround: Ensure each channel has a unique name.
l The automatic file upload (AFU) file queue shows a maximum of 15 files, Newer 15 and Top of the list buttons
do not work. All files are transfered, even though they are not listed.
Workaround: Wait for the queue to have fewer files in the list.
l Saving layout changes in a channel's layout editor and then immediately navigating to a different layout
occasionally causes the second layout to temporarily malfunction.
Workaround: Wait 1-2 seconds after pressing Save in the custom layout editor before performing further
actions on the page. If the error has already occurred, simply refresh the page in your web browser to restore
the malfunctioning layout.
l When deleting video or audio items in a custom layout and then navigating away from the page, the "Save"
prompt does not appear, and layout changes remain unsaved.
Workaround: Click the "Save" button at the bottom of the customer layout editor page to save all layout
changes before navigating to a different page.
Affecting Epiphan Live
l Navigating to the Switcher interface before the Dashboard monitoring panels finish loading any configured
channel or source previews can sometimes cause the monitoring panels to display an error upon return to the
Dashboard interface.
Workaround: Allow the monitoring panels to load any channel or source previews before navigating to the
switcher interface. If the error has already occured, simply refresh the page in your web brower to restore
monitoring panel previews.
l Streaming status on the Epiphan Live Dashboard interface does not include information regarding Wowza
Streaming Cloud transcoder settings.
Workaround: Ensure the transcoder in the Wowza Streaming Cloud web interface is enabled.
Affecting other areas
l Due to changes in the way channel layouts are created, some HTTP and RS-232 remote layout commands are
no longer available. These include values for setting the text overlay, logo, logo positioning, keep aspect ratio
and no signal image.
Workaround: Update your scripts to avoid using these commands. See the manual for a full list of available
commands.
l HTTP commands sent in quick succession are occasionally not properly executed, and may report incorrectly
that they were executed.
Workaround: For best results, add 1 second sleep or delay between HTTP commands.
l On Windows 10, the Movies & TV app fails to playback AVI files using AAC or MP3 audio and fails to playback
MP4 files with PCM or MP3 audio.
Workaround: If possible, use another video playback application. If you require playback by the Movies & TV
app, set your recording settings to use PCM audio if creating AVI files or to AAC audio if creating MP4 file
recordings.
l AFU status is sometimes inaccurately displayed in Epiphan Live and the Admin panel.
Workaround: Perform occasional manual confidence monitoring/debugging on AFU queue to ensure files are
being uploaded correctly.
