3D Stereoscopic
Io XT offers you the simplest path through 3D stereoscopic workflows.
Through SDI, you can output Discrete Left and Right Eye feeds with a simple Stereo
button choice in the AJA Control Panel. Additionally, muxed stereo output is
possible using a single SDI output. AJA hardware and software works in close
collaboration with CineForm's Neo3D software tools and CineForm codec to allow
stereoscopic editorial and viewing when working with Apple's Final Cut Pro 7 or
Adobe's CS5.5.
Through it's HDMI 1.4a output, Io XT makes it possible to connect to affordable 3Dcapable monitors for stereoscopic monitoring.
Io XT features hardware-based full 10-bit broadcast quality motion adaptive SD to
HD upconversion, HD to SD downconversion and HD to HD crossconversion.
The quality of the conversion features found in the Io XT is virtually identical to
AJA's award winning stand-alone converter products used throughout the post
production market. The Io XT built-in upconverter uses a a full 10-bit path, fully
motion adaptive de-interlacing, and large multi-point digital interpolators.
Downconversion uses large multi-point digital interpolators, anti-alias filtering and
Io XT Installation and Operation Manual — Overview
Crossconversion is high-quality hardware-based, providing capability to
streamline dailies and offers true broadcast picture quality in realtime. Because
these functions are in hardware, they are available full time, all the time—with no
CPU load. Such conversions are useful for cost effective monitoring, making
standard definition dubs of an HD project, or upconverting from a standard
definition FCP project to an HD deliverable.
About Primary & Secondary Video Formats
In Io XT operation, the Primary Format is the media format written to disk and
used in your project. The Secondary format is that which may be input for
capture or output from Io XT to VTRs or other devices. Down-conversion may be
applied to an input or on output.
The Primary Format menu allows you to select the video format used in your
current project.
Conversion is performed based on the Primary or Secondary Format settings.
Io XT can down-convert the input format (when designated as a Secondary
Format input) to the selected Primary Format. Or you can set a Secondary Format
output that will be a down-conversion of the Primary Format.
Convert Mode
Convert Mode allows selection of a mode for conversion between Highdefinition and Standard-definition formats. Io XT supports up-, down-, and crossconversion plus SD-to-SD aspect ratio conversions. See the following tables for
conversion options.
All conversions use AJA 10-bit hardware inside the Io XT.
For example, to do a down-conversion on an HD input:
Set the Primary Format as an SD format
Select the correct HD format with an (I) input designation for the Secondary
Format, then
Choose a “– Secondary” Video Input type
Down-conversion display mode choices that may be available include:
• Anamorphic: full-screen
• Letterbox: image is reduced with black top and bottom added to image area
with the aspect ratio preserved
• Crop: image is cropped horizontally to fit new screen size
The following Video Signal Formats are supported by Io XT.

Io XT Audio
Io XT provides an 8-channel audio engine for SDI embedded audio. The front panel
has a mini TRS headphone output with a lockable level control knob.
For analog audio output monitoring, Io XT provides a DB25 connector with eight
channels of audio to be used with industry standard Tascam-style audio breakout
cables. The front panel has an eight-channel VU meter display for monitoring levels.
Dual Link
Io XT supports Dual Link HD-SDI (4:4:4). Io XT supports the ingest and output of
SMPTE-372M compliant 4:4:4 RGB video and high-bandwidth 4:2:2 1080p 50,
1080p 59.94, and 1080p 60 at 10-bit.
Hardware-based Acceleration
Final Cut Pro 7 users will likely notice the DVCPROHD, HDV, and Apple RT Extreme
hardware acceleration provided by Io XT. This hardware acceleration was
developed in close cooperation with Apple. How does Io XT accelerate DVCPROHD,
HDV, and Apple RT Effects? A precision hardware scalar in Io XT does what the
Apple computer's processor would otherwise have to do, scale less than full-raster
HD (DVCProHD and HDV) to full-raster size, thus speeding up the system
considerably—and doing this scaling at full 10-bit broadcast quality.
Io XT Installation and Operation Manual — Overview
When using the Final Cut Pro 7 HDV codec, the Io XT advanced scaling engine takes the
native frame (long GOP 1440 HD) and outputs it via hardware-in real time. Precision
AJA circuitry re-sizes the video to full-raster 1920 x 1080, providing instantaneous
playback of HDV captured by Final Cut Pro 7 for both monitoring and recording.
Unlike the DV25 format, which can preview in realtime natively via Final Cut Pro 7, the
MPEG structure of HDV is much more complex. Fortunately, Io XT can provide real time
monitoring and playback to both HD and SD monitors and decks via the realtime
hardware scaler and down-converter on board.
In addition to speeding up Final Cut Pro 7 Dynamic RT by using the KONA scalar,
multiple frame size RT (1/4 size or full size)—a Final Cut Pro 7 feature—also benefits
from Io XT. The frame count and image size are dynamically changed during file
playback, so you don't get the “un-rendered” message in Final Cut Pro
1 7.

Cable Connections
Io XT connections are made directly to the unit’s rear connector plate. Eight audio
output channels are available through the Tascam-style DB25 connector.
Io XT Connectors
Io XT & Cables
HD/SD SDI Input and Output
BNC connectors are provided on Io XT for two HD/SD-SDI inputs and two HD/SD-SDI
outputs. The input and output support video and embedded 24-bit digital audio. Use
SDI wherever possible for the best quality 10-bit uncompressed video input, capture
and output. If peripheral equipment has a variety of inputs/outputs, look to see if it
has SDI I/O, and use it where possible. Most high-end professional broadcast
equipment supports SDI (VTRs, cameras, media storage servers, etc.).
HDMI Input and Output
Two HDMI connectors on the Io XT provide input and output of HDMI compatible
video and multi-channel embedded audio (8 channels). Input is HDMI v1.3a while
output is HDMI 1.4.
HDCP is not supported on either input or output. Io XT HDMI output does not have
HDCP, and input sources having HDCP are not supported. The HDMI input is
designed to support long cable runs—up to 100 ft. when using 22 or 24AWG HDMI
cable, or up to 50 ft. using 28 or 30AWG HDMI cable. The HDMI output supports
standard HDMI cables only.
The AJA Io XT Control Panel allows selection and adjustment of some HDMI
parameters; please see Chapter 3 for more information on Control Panel operation.
Balanced Analog Audio Out
Io XT provides 8 channel Balanced Analog Audio Output on a DB-25 connector
(Tascam-standard pinout, see the Specifications Appendix for this pinout). Audio
D/A converters are 24 bit.
Io XT Installation and Operation Manual — Cable Connections
RS422 Machine Control
A female DE-9 connector on Io XT provides connection for VTRs, camcorders, disk
media servers, and other devices using RS422 SMPTE (Sony) protocol. (Connector
pinout is listed in Appendix A: Specifications.)
Component Video Output (with Composite and Y/C functions)
Io XT features a group of 3 BNC connectors for output of component, composite and
Y/C functions. The signals are labelled on the BNC connectors on the rear panel of Io XT.
A Note About YPbPr—Component Video, or YPbPr, has been given several names
over time. YUV, Y/R-Y/B-Y, and YCbCr, are just some examples. Although these
various formats have some differences in levels, they are all basically the same. Io
1 three different
XT uses the modern YPbPr terminology exclusively. Io XT supports
types of YPbPr: SMPTE/EBU N10, Betacam (NTSC), and Betacam (NTSC Japan).
These three formats differ in level only and are configured in the Mac System via
the Io XT Control Panel.
Reference Video and LTC Input
Two BNC connectors on Io XT provide reference Input and Output. The Reference Video
input can also be used for LTC input. The selection of Reference (sync) or LTC is set using
the Io XT Control Panel.
In Video Pass-through mode, these connectors are effectively loop-through. Supplying
reference signal to the Reference input allows you to synchronize Io XT outputs to your
house analog reference video signal (or black burst). If you have a sync generator or
central piece of video equipment to use for synchronizing other video equipment in
your studio, then connect its analog composite output here. When Io XT outputs video,
it uses this reference signal for locking. When connecting a reference video source, the
locking signal should be the same format as the Primary format selected in the Io XT
Control Panel. It is possible in some circumstances to use an alternate format video
signal as long as the basic frame rate is compatible.
A standard 4-pin male XLR connector provides for 12-Volt DC power to the unit. You
can use either the supplied AC Adapter or furnish your own battery source. Since the
connector is an industry standard pinout, choices are varied and flexible. Many 3rd
party vendors offer products using this standardized power connector.
Pin 1: Pin 4: +
Pins 2 and 3: not used
Two Thunderbolt connectors are provided for connecting to a Mac that is Thunderboltenabled and for connecting to a Thunderbolt peripheral such as a RAID array or
Thunderbolt display. Please see the System and Software requirements presented
earlier in this Chapter when deciding on the type of Mac to connect.
Although the AJA Io XT supports “plug and play” functionality, many
applications do not recognize or operate properly if an input/output device
is removed while they are in use. AJA recommends that if the AJA Io XT is
ever removed while an application is in use, that the application be quit and
then relaunched after the AJA Io XT is reconnected.
The Io XT can host other devices from its second Thunderbolt connection;
however, caution should be used before unplugging the Io XT when other
items, such as storage arrays, are attached to the Io XT. Unplugging Io XT
will cause these devices to go off line since they will be disconnected from
the computer.

Chapter 2: Installation & Configuration
Installation Overview
The installation and set up of an Io XT is very simple. The steps of installation and
configuration are discussed here and summarized as follows:
1. Unpack the shipping box (see What’s in the Box later in this chapter.)
2. If not previously installed on your Thunderbolt equipped Macintosh, ensure
that appropriate application software such as Final Cut Pro 7, Avid Media
Composer, or Adobe Premiere 5.5 is installed as detailed in its user
3. For latest System Compatibility and Software Version information for Io XT:
Visit: http://www.aja.com/support/io/io-xt.php
4. Install AJA Io XT software on your Mac from the latest AJA download
(preferred) or from the supplied AJA CD-ROM.
Start by installing the Io XT driver package first, then install any AJA plug-ins
for 3rd-party software.
Installers for the Io XT driver software (with AJA Control Panel) are found both
on the CD in your shipping box and on the AJA website—we strongly
recommend going to AJA website to ensure you get the latest software and
5. Connect a Thunderbolt cable between the Mac and the Io XT.
6. Cable the system audio and video sources, VTR, audio monitor,
and video monitor.
7. When you run the AJA Control Panel, you’ll notice that the Io XT is autodiscovered as long as it is properly cabled and powered up.
Each of these steps are explained in greater detail on the remaining
pages of this chapter.
Connecting to your Computer
1. With your computer off, connect a Thunderbolt cable to one of the two
Thunderbolt ports
2. Connect the other Thunderbolt port to storage or other desired peripherals.
3. Assemble the Power Adapter and cable and connect to the Io XT 12V Power
4. Connect your desired Video I/O, Audio monitoring, reference, and machine
control cables. (Refer to Cabling the System following.)
5. Connect the Power Supply to AC power and turn on Io XT using the front
power switch.
Note: Ensure that the Apple, Adobe, or other software you are going to use has
been installed and used at least once before proceeding to the installation of Io
XT software. It is always a good idea to verify you have the most up-to-date
release of your AJA software by checking the AJA support site:

Installing Io XT Software
Go to the AJA website and download the latest Io XT driver software and any AJA plugins for 3rd-part applications (such as Adobe CS5.5). All of these software installers can
be found here:
If you don’t have an appropriate internet connection, use the CD-ROM supplied with
the Io XT system to install necessary software drivers. You cannot use Io XT with thirdparty software until the AJA Io XT software has been installed on the host workstation,
plus any AJA plug-ins required.
System software updates may occasionally become available to AJA1 Io XT owners on
our website (www.aja.com). We recommend checking occasionally for both software
updates and additional product information.
Note: If your computer has previously had another video capture or multimedia
device installed, ensure you uninstall any related software before installing Io XT
This will prevent any hardware or software conflicts.
If you add Io XT supported applications at a later date and have not previously installed
the appropriate drivers, you must run the install program again selecting the
appropriate application support software to be installed.
Macintosh Software
Note: Before installing Io XT software, turn off any virus protection and security
software that you may have installed on your computer.
1. For CD-ROM: Insert the Io XT CD in the Mac, locate the Io XT CD icon on the OS X
desktop. Double click the icon to see the CD contents, which will appear in its
own window.
2. Locate the package files (download or CD); they have an icon that looks like a
box and has a “.pkg” or “.mpkg” suffix.
Note: Files ending in the “.pkg” and “.mpkg” suffix are OS X installer files. These launch
the OS X installer and tell it where and what to install on your system.
3. Double-click the package to log on and begin software installation. Start by
installing the Io XT driver package first and then finally install any AJA plug-ins
for 3rd-party software.
4. On the following pages, we show the series of screens you’ll see when installing
the Io XT driver software package.
Note: During installation the system will ask you to authenticate who you are as
currently defined on your OS X user profile. Enter the proper name and password at
the Authenticate prompt; if you have multiple users defined, ensure that you log on
as a user with administrator-level authority.
5. When you launch the installer, you’ll see a series of installer screens.

16.Finally, install any AJA plug-ins required for 3rd-party software. These will have to
be downloaded from the AJA website: http://www.aja.com/support/io/io-xt.php
For example, if you wish to use the Io XT with Adobe Premiere or Adobe After
Effects, you would go the AJA website Io XT support page (URL above) and
download the “AJA Mac Plug-ins for Adobe CS5.5”. These plug-ins come with
complete documentation on how to use them.
Genlock and Your System
For video stability and proper system operation, you can genlock all equipment to
house sync, however genlock is not required for Io XT due to excellent freerun
accuracy. To connect genlock, use a black burst generator output looped through the
system. On the Io XT house sync is connected to “LTC/Ref In”.
Note: Be sure to set the Reference/LTC connection to Reference in the AJA Control

Using Io XT with Professional Video /Audio Software
After you install the Io XT software and any AJA plug-ins to support your choice of
3rd-party software, you’re then ready to begin capturing and playing back video and
Go here to look for AJA plug-ins and documentation for your favorite 3rd-party
software applications:
Once you’ve installed all the AJA software as detailed in Chapter 2, you’ll find the AJA
Control Panel application in your Mac Applications folder.
AJA Control Panel Overview
The AJA Io XT Control Panel is a software application that provides a simple visual
window showing how the Io XT interface is currently configured, and that allows
you to make changes. Settings—both those you changed and those you didn’t—
can be saved as a snapshot for recall at anytime. This lets you save settings
associated with all your frequent tasks; then as you switch tasks you don’t have to
spend extra time resetting interface configurations—just load the previously saved
settings for each task.
One thing you’ll notice instantly about the Control Panel is that it represents a
visual block diagram of how the unit is configured. The current status, input and
output settings, and many other details can be viewed as a color-coded block
diagram in the Control Panel.
To ensure you make the most of the software, launch the AJA/Io XT Control Panel
application and look at its display. Then refer to the “Basics” described here to fully
understand what you’re seeing and learn how to view and change the Io XT system
Before we go into too much detail, here are some basic definitions you should
know (please refer to the figure that follows for reference). After studying the
basics, read “Who is Controlling Io XT?” later in this chapter for more advanced
information on how applications interact with Io XT.
Block Diagram Screen—The top area of the Control Panel
shows a visual picture representing the processing (if
any) that’s currently occurring, including inputs/
outputs, reference source, and system status. Lines
between inputs, the framebuffer, and outputs, show a
video path. Where there are no lines, it shows there is
no connection; this can be because an input or output
isn’t selected. The lines will also show whether the
outputs are video or video + key.
an Icon Produces
a Context-sensitive
Icon objects on the block diagram screen (input/output icons, frame buffer,
etc.—also called “widgets”—indicate their status by color (explained later) and
can be clicked for context-sensitive information and choices. (These same
choices can also be made from the tabbed Control Panel screens.)

AJA Control Panel, Block Diagram
Framebuffer—The framebuffer is the “engine” in Io XT where active video
operations take place using Final Cut Pro, other 3rd-party applications, or
even Io XT itself. The framebuffer has a format (called the “Primary Format”
and color space that it follows, as defined in the Tabbed Windows or via
external application software (such as the “Easy Setups” in Final Cut). It is
important to realize that inside the Macintosh many applications can use the
Io XT (as you switch from window to window) and it may not always be
obvious which currently controls it.
The Control Panel displays the name of the application controlling the Io XT.
In some cases, applications may not always properly “let go” of the I/O
interface as another takes over—you’ll be able to tell by looking at the
Control Panel.
Primary Format—The video format currently assigned to Io XT. This is the
format that the framebuffer will use and is shown in the Control Panel using
the color blue. All icons in blue are the same as the Primary Format used by
the framebuffer. Also any text descriptions in the block diagram that appear
in blue also indicate that something is in the primary format. So, for example,
if you see that the input and output icons are blue, then you know that the
same format is used throughout the video path and that no format
conversion is being performed. If a different color is displayed on the input or
output, say green for example, then you know that Io XT is performing a
format conversion in the video path.
Secondary Format—Any format other than the currently selected Primary
Format, is a secondary format. As described previously, this means that either
the Inputs or Outputs are somehow different from the framebuffer’s assigned
format (i.e., the “Primary Format”). This can be seen at a glance because the
color will be different than blue.
Input/Output Icons—The input and output icons are triangles that together with
their color show all the input and outputs and their status (selected, not
selected, input present or not, format, etc.). A complete video path is shown
when inputs and outputs are connected with lines going to/from the
Input/Output Icon
Conversion Icons—when an input or output is a different standard than the
framebuffer, the Io XT may be up- down- or cross-converting the signal to the
selected standard. This may be automatic, because it's detected an input signal
that differs from the standard currently selected, or because you've explicitly
told it to convert. In either case, the block diagram will show the conversion by
displaying a conversion icon in between the input/output and the framebuffer.
Color Meanings—All items in the Io XT Control Panel block diagram are colorcoded to show what is happening in realtime. This applies to both icons and text.
These colors have the following corresponding meanings:
Blue: video is same format as the Primary Format (framebuffer)
Red: the selected operation cannot be performed
Yellow: reference video (black burst or other reference source)
Green: indicates that Io XT is performing an active change to the video
making it different from the Primary Format (e.g., down-conversion).
Control Panel Screens—The side area of the Io XT Control Panel provides different
information categorized by topics. Clicking on a topic—or a block diagram
element—displays an information screen corresponding to that topic. Screens that
can be selected are:
Control: configures Io XT operation and output timing.
Format: select the framebuffer primary video format and any secondary formats
for conversion of inputs/outputs
Input Select: view and edit input selections and how they are mapped
SDI Out: select output format
HDMI: configure the HDMI I/O
Analog Out: configure the component/composite analog output
Video Setup: configures Video such as composite black level.
Audio Setup: configures Audio options such as analog audio monitor level.
DS Keyer: setup and control the insertion of keyed video from the frame buffer or
graphics files with alpha channel.
Timecode: monitor RP-188 timecode and configure timecode window burn output
(Note: SMPTE 12M-2 is the updated name and specification for what was RP-188)
Presets: add or delete saved preset configurations (handy for setting up the Io XT
for certain workflows and then saving it as a canned configuration for easy later

Block Diagram Screen – the top area of the AJA Control Panel shows a visual picture
representing the processing (if any) that's currently occurring, including inputs/
outputs, any up/down/cross conversion, reference source, and system status. Lines
between inputs, the framebuffer, and outputs, show a video path. Where there are
no lines, it shows there is no connection; this can be either because an input or
output isn't selected or because no video is present at the selected input. The lines
will also show whether the input or outputs are single inputs/outputs, video or
video + key.
Icon objects on the block diagram screen (input/output icons, frame buffer, etc.also called “widgets”-indicate their status by color (explained later) and can be
clicked for context-sensitive information and choices. (These same choices can also
be made from the tabbed Control panel screens.)

Color Meanings—all items in the AJA Control Panel block diagram are color-coded to
show what is happening in realtime. This applies to both icons and text. These
colors have the following corresponding meanings:
Blue: video is same format as the Primary Format (framebuffer)
Red: the selected operation cannot be performed or an invalid selection has been
Yellow: reference video (black burst or other reference source)
Green: indicates that the Io XT is performing some kind of active change to the
video, to make it different from the Primary Format (e.g., up/down convert, format
change, etc.).
Control Panel Operation
Control Tab Screen
The Io XT can be controlled by various software applications running on a host Mac.
The Control Tab is where you select how the Io XT directs video and is used by
application software. This screen also provides control for configuring output timing
with regard to external reference video and horizontal/vertical delay.
At the top of the Control screen it will show the current Default Output and the
application currently controlling the Io XT.
AJA Control Panel, Control Tab
Control Tab Screen Settings
Default Video Output—this is where you select what Io XT will output as a default
when no application has control of the board, such as when the Finder is active. Since
Io XT can be controlled by software applications as well as its own control panel, the
output can change dynamically. When you select many video applications, they will
grab control of the Io XT inputs/outputs. These settings determine what happens
when an application that doesn't grab the Io XT inputs/outputs is active.
Default Output Choices and their meanings:
Black: this selection directs Io XT to output video black whenever an
application isn't controlling the card.
Io XT Installation and Operation Manual — Control Panel Operation
Input Pass through: this selection directs Io XT to route video from its selected
input through the card for processing and output. When this selection is in
effect, all Primary/Secondary Format selections are available for selection in
controlling the output. This in effect makes the Io XT a converter when used in
conjunction with the AJA Control Panel application and a Mac. No applications
other than the AJA Control Panel need to be open to convert audio and video
from one format to another. For example, if an SD source tape needs to be
dubbed to an HD tape, the signal might be routed from the SD VTR to the Io XT,
configured for upconversion in the AJA Control Panel and then passed through
to the HD VTR for recording.
Test Pattern: this selection directs Io XT to output a choice of preset pattern
when no other application is using the Io XT. You can choose from:
Black, Color bars (75% or 100%), Ramp, Multiburst, Line Sweep, Multi Pattern, or
Flat Field.
In addition to the preset test pattern choices, a “Load File...” selection at the
bottom of the menu allows you to load any standard Mac RGB graphics file
(.tif,.psd, etc.) into the frame buffer for display.
While in Test Pattern mode, you can select RGB or YUV output via a pulldown
Note: the graphic file will not be scaled to fit. If it's smaller than the current frame
buffer format, Io XT will center it in the frame. If it's larger than the current frame
buffer format, it will be cropped on the right and bottom. Also some graphics
formats and bit depths may not be supported. Once a graphic file is loaded into the
frame buffer it will be retained until it is overwritten by another graphic or test
pattern, or when power is turned off. Graphic file names are only “remembered” in
the menu as long as the AJA Control Panel application is running.
Hold Last Application: this selection directs Io XT to hold and output the last
frame of video from the last application to control Io XT. This can be helpful
when operating in an environment where you're switching back and forth
between multiple application windows.
Tip: pressing and holding the Apple COMMAND key while clicking in the AJA
Control panel—while in any software application—causes control of the Io XT to
stay with that application, rather than shifting to the Control Panel. This works
regardless of the setting of “Default Output.”
Playback Timing—Use these controls to set Genlock and Timing adjustment.
Genlock (Freerun, Ref In, Video In)—selects how Io XT will synchronize program video:
Freerun: In this mode, Io XT generates sync without an external reference source
Ref In: Directs Io XT to use the Ref Video source for sync (usually an analog black
burst video signal)
Video In: Directs Io XT to use whichever video input source has been selected in the
Inputs tab window for sync
Timing (Horiz and Vert)—these two pull-downs allow output timing adjustment with
reference to the Ref Video source selected. The Horizontal reference can be
adjusted by selecting a number of pixels (clocks) to offset. Vertical can be adjusted
by specifying a number of lines to offset.
Format Tab Screen
The Formats screen shows the video format currently in use by the Io XT framebuffer
(called the Primary Format) and allows you to change it. All throughout the Control
Panel, choices are always presented based on what Io XT can do with the signals
available and the inputs/outputs selected. For example, on the Format screen, if the
output or inputs are a different format than the primary, then you’ll see an additional
information pane that allows you to view and edit the secondary format—including
control over whether up/down/cross conversion is employed.
AJA Control Panel, Formats Tab
Format Tab Screen Settings
Video Format (Primary and Secondary)—these pull-down menus show the
currently selected formats. If you select an alternate value in the Primary Format
using the pull-down, it will change the format used by Io XT's framebuffer. When
a change is made via the Video Format pull-down or by clicking an icon (widget)
and selecting a new format via a contextual menu, the block diagram will change
to reflect the new format. In the case of a Secondary Format, the formats
available can vary based on what the Primary Format is and the input signal
(frame rates of input sources limits the to/from conversion choices). The
“Secondary Video Format” pull-down menu lists all compatible formats for
selection (incompatible formats are not shown). This allows you to see what
you've chosen, and also see those formats that are compatible with the selected
Primary format.
The RGB Range pulldown menu allows you to select either Full range (0-1023) or
SMPTE range (typically 64-940) for RGB color output.
Io XT Installation and Operation Manual — Control Panel Operation
Io XT Formats include:
525i 23.98
525i 29.97
625i 25
720p 23.98
720p 59.94
720p 60

1080i 30
1080sf 23.98
1080sf 24
1080sf 25
1080sf 29.97
1080sf 30
Note: The AJA Control Panel software uses the abbreviation “sf” instead of “psf” when
referring to “progressive segmented frame” formats. In the manual and in other
literature you may see either of these acronyms used interchangeably. Visually it is
easier to discern at a glance if you are working with progressively segmented frame
formats (sf in the AJA Control Panel) as compared to progressive frame formats
which will show only “p.”
Crossconversion: if you have an HD format as your primary and then select a
secondary HD format with a different frame size, the Io XT will perform a
crossconversion where necessary (input or output) for “like Hz” formats. “Like Hz”
means that 720P 59.94 may be converted to 1080i 29.97 (59.94Hz). Converting
from disparate Hz is not supported on the Io XT for crossconversions. The example
below shows 1080i to 720p.
Up (Conversion)—the Up and Down pull-down menus are available when conversion
has been selected for the video path to/from the framebuffer and like Hz formats
are selected (the one exception is 1080PsF 23.98 which can be downconverted to
525i 29.97.) Different choices will be available depending on the type of conversion
and formats being converted. SD to SD conversions are essentially aspect ratio
conversions to accommodate transforming anamorphic images to letterbox or
vice versa.
For Upconversion the following choices are available:
Anamorphic: full-screen “stretched” image
Pillar box 4:3: results in a 4:3 image in center of screen with black sidebars
Zoom 14:9: results in a 4:3 image zoomed slightly to fill a 14:9 image
with black sidebars
Zoom Letterbox: results in image zoomed to fill full screen
Zoom Wide: results in a combination of zoom and horizontal stretch to fill
a 16:9 screen; this setting can introduce a small aspect ratio change
Down (Conversion)—for downconversion the following choices are available:
Letterbox: image is reduced with black top and bottom added to image area with
the aspect ratio preserved
Crop: image is cropped to fit new screen size
Anamorphic: full-screen “stretched” image
SD to SD—this pulldown is for SD to SD aspect ratio conversion.
Letterbox: this transforms SD anamorphic material to a letterboxed image.
H Crop: will produce a horizontally stretched effect on the image; transforms
anamorphic SD to full frame SD
Pillarbox: will produce an image in the center of the screen with black borders on the
left and right sides and an anamorphized image in the center
V Crop: will transform SD letterbox material to an anamorphic image

Input Select Tab
On the Inputs screen you can view the currently selected video and audio input
sources and map audio sources to the channels supported by Final Cut Pro (more on
this later). Two information panes in the screen are provided: Video Input and Audio
AJA Control Panel, Inputs Tab
Input Select Tab Settings
Video Input—the pulldown menu allows you to see and change what's currently
selected and the video format that Io XT has detected (if any). In the example
shown previously, it shows that video is selected at the HDMI input and the format
is 1080i with a frame rate of 29.97. Since this text is shown in blue, you can tell that
it matches the framebuffer's primary format selected in the “Formats” screen. By
looking at the input source, you can determine how the primary format should
likely be set (unless you want to perform a conversion on input.) If you wish to
select a different input use the pulldown to select either SDI 1, 2 or Dual Link for
two-wire 4:4:4 RGB, or Stereo 3D. For 3G single-link, choose the SDI Source used
and select Stereo 3D from the SDI pulldown menu.
Use the LTC/Ref menu pulldown next to Video Input to select how the LTC BNC is
used: selecting Reference means it’s used a Reference standard; selecting LTC
means it’s used for lateral time code (LTC) input.
Audio Input—this pulldown menu allows you to pick where the audio comes from. Io
XT supports up to 8 channels of embedded audio. You can choose out of 16
channels embedded in the SDI which 8 to bring in (1-8 or 9-16). Here you can also
select which two channels from the 8 embedded would be mapped to Final Cut
Pro if only two channels were selected in that application.
SDI Output Tab
The SDI Output tab shows the current settings for both of the SDI outputs. Because
the outputs can be configured independently, one output may be the Primary format
and the other output may be the Secondary format. If an input/output has no video,
it will be indicated on the block diagram (“No Video”).
SDI Output Tab Screen Settings—SDI Output 1 and 2
Configure SDI 1 and 2 via pulldowns:
AJA Control Panel, SDI Output Tab
Select Options:
Primary—when selected, this indicates that the SDI output is set to the same format
as the framebuffer. That value will be listed in blue.
Secondary—when selected, this indicates that the SDI output is set to a format
different from the framebuffer (Primary Format). That secondary format value
will be listed in green. This shows that active processing of the video is taking
place (format change and possibly even up/down-conversion).
Video+Key—when selected, this indicates that the SDI 3 video is set to the same
format as the framebuffer. SDI 4 is set to a video key signal associated with SDI 3
(the shape to be cut out from the video - this will appear as a black and white
image/matte). Using the second Io XT output as an Alpha Channel key, with the
video output, may be useful for feeding production switchers, DVEs or other
professional video equipment. If Video+Key has been selected as an output, the
block diagram will indicate the SDI outputs with video in blue and the key in red.
Stereo—when selected, this indicates that SDI 1 represents the left eye output and
SDI 2 represents the right eye output of stereoscopic material.Io XT also offers
single link 3Gb output of multiplexed Stereo 3D.
Io XT Installation and Operation Manual — Control Panel Operation
Dual Stream Options:
Dual Link—output (SMPTE 372M) using SDI 1 and SDI 1 in concert.
3Gb—output (SMPTE 424M) using a single-link transport.
HDMI Tab Screen
The Io XT’s HDMI input and output are shown and configured at this tab screen.
HDMI Output Settings—the Source pulldown menu allows you to select either the
primary video format (framebuffer) or a secondary one (up/down/crossconversion).
Pulldowns are also provided for configuring the video output range, color space
and number of embedded audio channels (2 or 8) for the HDMI output. A Protocol
pulldown allows you to choose either “HDMI” or “DVI” protocol—use DVI if you’re
outputting to a DVI monitor using an HDMI to DVI adapter.
A pulldown menu for 3D output allows you to select either Side-by-Side or TopBottom (Stacked) output of left-eye and right-eye signals.
Note: This selection must agree with format selection in the third-party CineForm
Codec (NOT included with AJA Io XT) pulldown menu.
Audio Channels—an Audio Channel pulldown allows you to select the number of
embedded audio channels for the HDMI output.
HDMI Input Settings—the detected HDMI input video format is displayed and you’re
given a chance to configure the RGB range (SMPTE or FULL) and select any two
embedded channel pairs from those supplied for Final Cut Pro stereo output (if

QuickTime Video Output Filter—The QuickTime Video Output Display Filter is
designed to help manage the comprehensive list of video outputs that may be
available to applications, particularly Final Cut Pro's A/V Devices tab.
By selecting the checkbox next to specified parameters, the video outputs related
to these specified parameters are enabled as possible video outputs for
applications. For example, if the checkbox next to 25/50 is unchecked, 50Hz video
outputs are deselected and would not be available to the user in the A/V Devices
tab of Final Cut Pro. To avoid confusion when working in a particular editorial
environment, users might elect to leave 50Hz unchecked if they work solely in a
60Hz editorial environment. The same might be true for users who do not intend
to work with true progressive 1080 material.
Note: If a prompt occurs in Final Cut Pro stating that the AJA output device is
missing, this may be due to the Active Video Filter for a given parameter being
unchecked for the format selected in the application. If this occurs, make the
appropriate selection in the Control Panel application and re-enter Final Cut Pro
where the selection should now be available.
Audio Setup Tab
This screen shows the current settings for the analog audio output, allowing you to
re-configure it when desired.

Lock Audio Gain To Unity—When set, the Io XT will ignore the Final Cut Pro gain
setting and set the audio gain at unity. When not set, this checkbox tells the Io XT
to get the audio gain setting from Final Cut Pro.
Analog Audio Monitor Level—This selection determines the audio level that will
appear at the analog audio outputs (“FSD” is full-scale-deflection reading as
measured on a VU meter). Select +18 for Europe or +24 for USA.
Io XT Installation and Operation Manual — Control Panel Operation
DS Keyer Tab Screen
The Io XT has a hardware-based downstream keyer that is ideal for putting logos,
“bugs” or other video material with an alpha channel on top of video being played out
or printed to tape. A typical application would be putting a television station's call
letters or channel over program video content. Keyed video can be from the Io XT
internal Frame Buffer (from storage, video In, etc.) or from a graphics file that has an
alpha channel (PhotoShop etc.).
AJA Control Panel, Downstream Keyer Tab
Settings in the DS Keyer tab provide control over how the keyer operates and whether
it's turned on or off. Controls and their meanings in the Tabbed screen are as follows:
Downstream Keyer Off — when this pulldown menu item is selected the
downstream keyer will be turned off
Frame Buffer over Matte— places the keyed video with alpha channel currently
in the Frame Buffer over a fixed color matte determined by the “Matte Color”
setting set separately.
Frame Buffer over Video In—places the keyed video currently in the Frame
Buffer over the video input for playout or print-to-tape.
Graphic over Matte—places a graphics file having an alpha channel (chosen in
“Graphic File” pulldown) over a fixed color matte determined by the “Matte Color”
setting set separately.
Graphic over Video In—places a graphics file having an alpha channel (chosen in
“Graphic File” pulldown) over the video input for playout or print-to-tape.
Graphic over Frame Buffer—places a graphics file having an alpha channel
(chosen in “Graphic File” pulldown) over the current contents of the Io XT Frame
Buffer (which might be from storage, video In, etc.).
Matte Color: only available when the pulldown “Frame Buffer over Matte” or
“Graphic over Matte” are selected-pressing this button brings up a color
selection dialog. The dialog provides a variety of ways to select a matte color
including a color wheel, color picker (choose from a location anywhere on the
computer screen), numeric sliders, swatches, “crayons”, and spectrums. The
matte chosen will be used as a video background under the keyed video.
Foreground pre-multiplied (checkbox): use to avoid “matte lines” and improve the
appearance of the foreground (key) being composited over the background.
Audio Out:
Frame Buffer—select audio out to be routed from the Frame Buffer.
Audio In—select audio out to be routed from the Io XT’s selected input(s).
Graphic File: this pulldown allows you to choose from any recently accessed file or
select a new file (“Load File...”), which then brings up a file dialogue. Remember
that the file raster (pixel x pixel count) should match the primary format in the
frame buffer or the secondary format if upconverting. Example: you wish to key a
logo on top of your 1920x1080 footage, the still image with alpha channel that
you load should be 1920x1080.
Timecode Screen
The timecode screen is used for both monitoring the RP-188 timecode embedded in
the digital data stream and for selecting a timecode offset (if required) for the
attached VTR (connected to the RS-422 port)—and sent during assemble-edit mode.
Note: SMPTE 12M-2 is the updated name and specification for what was RP-188.
AJA Control Panel, Timecode Tab
Io XT Installation and Operation Manual — Control Panel Operation
Timecode Screen Settings
RP-188 Timecode <n>—in RP-188 timecode (SMPTE 12M-2) there can be multiple
timecode values in the data stream. Use this pull-down to select the one you wish
to monitor. The selection will be displayed in the timecode value displayed to the
right of the pull-down.

Use QuickTime Timecode—when checked, this directs Io XT to output timecode from
the QuickTime timecode track. When not checked, Io XT uses the Output Timecode
Offset value plus the number of frames into the movie. Note: not all QuickTime
applications use or support timecode tracks—so sometimes the QuickTime
timecode is missing or not meaningful.
Output Timecode Offset (entry field and FPS pull-down)—this text entry field allows
you to specify a timecode offset for use with Final Cut Pro 7 (or any other
application that has timecode offsets that are user-controlled). In FCP, go to
“Timeline Options” and locate the “Starting Timecode” value. Use that same value
here as the “Output Timecode Offset” to ensure the timecode is synchronized.
Timecode Burn-in—this pulldown selects whether the timecode value is “burned-in”
on video output from Io XT.
If set to “OFF”, timecode will not be keyed over the video. If set to
“timecode”, then the timecode value will be keyed over the output
video. This can be useful for synchronizing, choosing edit points,
dailies, and many other purposes.
Note: SMPTE RP 188 defines a standard for the transmission of time code and control
code in the ancillary data space of a digital television data stream. Time code
information is transmitted in the ancillary data space as defined in ANSI/SMPTE
291M. Multiple codes can be transmitted within a single digital video data stream.
Other time information, such as real time clock, DTTR tape timer information, and
other user-defined information, may also be carried in the ancillary time code
packet instead of time code. The actual information transmitted through the
interface is identified by the coding of a distributed binary bit. Equipment
manufacturers can use the meta data for different purposes.
Presets Screen
After configuring the AJA Control Panel Tabbed screens, you can then save all your
settings as a snapshot for later recall—called a preset. In this way, you can organize
presets for all your typical tasks, eliminating time-robbing manual reconfiguration
each time. To save a preset, simply go to the Presets screen and click “Save Preset”. A
dialog will be presented asking you for a name; enter a meaningful name and click
“OK”. Thereafter the preset will be available under the Control Panel “Presets” list.
Presets Screen
From the Presets screen you can manage your collection of presets easily. To Load or
Delete a stored preset, just select it with your mouse and then click the “Load Preset”
or “Delete” button respectively.
