PIX 250i User Guide and Technical Information
Introduction
The PIX 250i is a rack-mountable, production video recorder with extensive audio and video processing capabilities. The foundation of the PIX 250i is hardware-based, 10-bit video up/down/cross
conversion, and hardware-based encoding to Apple ProRes and Avid DNxHD codecs (both up to
12-bit 4:4:4). These features allow for fast, reliable acquisition of video (at any standard HD or SD
resolution and frame rate) and audio (up to 16 tracks from Analog, AES, HDMI, or SDI sources) to
ready-for-edit, industry standard QuickTime .mov files.
Files are recorded simultaneously on (up to) 2 separate, 2.5” SSD storage devices via two front panel
PIX-CADDY slots. This redundancy in local, removable storage devices, coupled with standard,
Ethernet-based file transfer features further reduces steps in the production workflow. Gigabit Ethernet network ports enable remote access to recorded files and the ability to transfer them quickly into
a post-production environment.
Full-featured precision timecode and sync reference I/O using Ambient Clockit core technology is
provided to allow tight synchronization with external equipment in complex multi-machine configurations. The PIX 250i supports various external control options: RS-422, GPIO, SDI flags, Timecode
triggering, and an embedded web server for network-based remote control. Network Grouping
functionality enables linked, frame-synchronized recording and playback of multiple PIX 250i units
connected to a standard Ethernet network.
Introduction
This User Guide details installation and operation of the PIX 250i. This User Guide corresponds to
PIX 250i firmware version 2.000. User Guide revisions are released at the same time as firmware
updates and available online:
http://www.sounddevices.com/products/pix250i/downloads/
Manual Conventions
Several formatting features have been included to make navigating the guide easier.
• Physical buttons on the PIX 250i are represented with capital letters (REC button, MENU button,
etc). All physical button names are detailed in the Panel Descriptions section.
• Button combinations are represented with the plus (+) symbol. For example: “Press LCD button+
AUDIO button” means to first hold down the LCD button, then press the AUDIO button, and
finally release both buttons.
• Setup Menu items are indicated with this text: [Menu Category - Parameter], where the menu
category is one of the items in the list displayed when the MENU button is pushed, and the
parameter is an item in the list displayed when that category is selected (by pushing in on the
Control Knob).
• Blue italicized text references sections of the user guide containing contextually relevant information. When viewing this document on a computer, this text can be clicked to jump to the named
section.

PIX 250i User Guide and Technical Information
Recording
The PIX 250i records video and audio together to a QuickTime .mov file. The PIX 250i can record to
up to two drives simultaneously or in sequence (Setup Menu option [File Storage - Record Mode]).
Each drive can be configured independently to be available for recording, available for playback
(read-only), shared on the network via Samba, or switched to network sharing after becoming full
(Setup Menu option [File Storage - Drive Record/Network Mode]). Any number of PIX 250i units
can be assigned to one of four available network groups for grouped record and playback of video
on multiple units simultaneously (See “Network Grouping”, page 40).
Pressing the REC button will start recording provided there is valid video signal present. Recording
will continue until the Stop () button is pressed or until all available media is full. Record and Stop
can also be triggered by other devices via a web browser, RS-422, GPIO, SDI Triggers, and Timecode.
External control of such functions is set in Remote Control. See External Control and Timecode for more
details
While recording, the REC button will illuminate red and the OSD items Timecode, File Name, ABS
Time, and drives actively recording turn red. The PIX 250i is a record-priority device and will enter
record any time the REC button is pressed. If the PIX 250i is not ready to record when a record command is given, the PIX 250i will enter a Record Pending state. In this state the REC button will flash
red. This is usually caused by file storage mounting or response time, loss of video input, or Play/
Pause/Shuttle.
Recording
The Setup Menu is not accessible during recording and playback. The File List is not accessible during Playback.
Recorded video files are split automatically at the interval selected in Setup Menu option [File Storage - QuickTime File Split every]. When the Setup Menu option
[System - REC button File Split] is set to On, pushing the REC button during recording will split
the file manually (Unless Setup Menu option [File Storage - QuickTime File Split every] is set to

Selecting Video File Resolution and Frame Rate
The PIX 250i can record video in numerous resolutions and frame rates. The Setup Menu option
[Video - File Resolution/Rate] sets the resolution and frame rate of recorded QuickTime files. This
Setup Menu option also determines the resolution and frame rate of the live HDMI and SDI output

• 720p24
• 720p23.976
• 576i50 *
• 480i59.94 *
Recording
When Setup Menu option [Video - File Resolution/Rate] is set to Same as Video Input, recorded
QuickTime files and video output signals will be of the same resolution and frame rate as the input
video signal.
* Standard definition recording is only available for ProRes 422 HQ, ProRes 422, and ProRes 422 Proxy.
Progressive Segmented Frames (PsF)
Some cameras output video signal in progressive segmented frames (PsF). PsF is a method for
transmitting progressive video in an interlaced stream. A device generates PsF signal by splitting
each frame into two segments. PsF segments are the same as interlaced fields in that one segment
represents the even lines of a frame and the other segment represents the odd lines of a frame. PsF
segments differ from interlaced fields in that there is no motion between each segment in a pair.
The PIX 250i will automatically sense PsF signal from most cameras that output PsF over SDI. This
is accomplished through the use of a flag inserted into the SDI signal by the camera. If a camera does
not insert this flag into the SDI stream or if it outputs PsF signal over HDMI, then the Setup Menu
option [Video - Input PsF Detect] can be set to Interpret 1080i as PsF. This will force the PIX 250i to
treat all 1080i signal as if it were PsF and deinterlace it accordingly.
Selecting a Video Codec
Setup Menu option: [Video - Codec].
The PIX 250i has two families of intra-frame, DCT based codecs available: Apple ProRes and Avid
DNxHD, with five levels of compression for ProRes and four levels of data compression available for
DNxHD. Both codecs are intermediate codecs that assist the editing process by eliminating the need
to transcode video before importing into Final Cut (ProRes) or Avid (ProRes or DNxHD).
ProRes is a variable data rate codec; DNxHD is a fixed data rate codec. PIX 250i supports all compression levels and bit rates of DNxHD and ProRes and automatically records the correct bit rate
dependent upon the video input resolutions and frame rate. The data rates indicated in the Setup
Menu item [Video - Codec] indicate the maximum data rate at 1080p30.
23
PIX 250i User Guide and Technical Information
DNxHD 36 Mb/s only supports 1080p signal. Standard definition recording is only available for ProRes
422 HQ, ProRes 422, and ProRes 422 Proxy.
Interruption of Signal During Recording
In the event that video signal is lost (an unplugged HDMI or SDI cable, for example) during recording, the PIX 250i will pause the recording and wait for video signal to be re-initialized. If video signal
is re-initialized, recording will begin again to a new file of the same name with an “A” appended to
the end. Further interruptions of signal during that take will cause an alphabetic filename progression (“B”, “C”, etc).
Alignment of Audio and Video
An advantage to recording audio on the PIX 250i along with the video is the elimination of audio/
video sync problems in post. The PIX 250i has many options regarding audio sources along with the
two options for video inputs, HDMI and SDI. Given this flexibility, care must still be taken to ensure
good audio/video sync.
If recording camera audio embedded on HDMI or SDI, then the audio/video alignment will be excellent provided the alignment is proper on the camera.
Recording
If recording audio using the dedicated audio inputs (Analog or AES), then a delay may need to be
dialed in. The reason for this is that some cameras have a delay of one or more frames from lens to
SDI/HDMI output. The PIX 250i on the other hand has no appreciable delay between audio and
video. This means that if the camera does have this delay, the audio will lead the video as recorded
by the PIX 250i. Note that on some cameras, the lens-to-SDI/HDMI delay changes with resolution/
frame rate. The best practice is to test the audio/video sync using sticks on a test file for each camera
resolution/frame rate to be used on a project before starting. See Audio Input Delay Control for details
Audio Track Arming
Up to 16 Tracks of audio can be recorded. Tracks must be armed in the Audio Screen in order for
them to be recorded. Armed audio tracks will have a red background in the Arm column. Unarmed
audio tracks will have a black background in the Arm column. To arm or disarm Tracks for recording:
1. Press the AUDIO button to access the Audio Screen.
2. Rotate the Control Knob to select the desired track.
3. Press the Control Knob to focus the highlighter on the selected track’s parameters. The highlighter will become orange and focus on a single column in the track.
4. Rotate the Control Knob to highlight the Arm column (The Arm column is the left-most column and displays the track number).
5. Press the Control Knob to access the Arm Menu. Turn the Control Knob to select On, Off,
All On, or All Off. (All On and All Off will change the arming status of all tracks, regardless
of which track the Arm Menu is being accessed from).
Changing a track’s Input Source to Off will disarm the track.

PIX 250i User Guide and Technical Information
Video Scaling and Frame Rate Conversion
The PIX 250i features powerful, hardware-based video scaling, frame rate conversion, and de-interlacing. This allows for converting the resolution and frame rate of input video signal to the recorded
file and to the HDMI and SDI outputs in real-time.
Video Scaling & Frame Rate Conversion
Video scaling and/or de-interlacing is active whenever the Setup Menu option
[Video - File Resolution/Rate] is set to something other than Same as Video Input. Any supported input signal can be converted to any available resolution. When set to record progressive frames, the PIX 250i will convert incoming interlaced video to progressive frame video
via its built-in, powerful, hardware-based de-interlacer. The PIX 250i will also convert progressive segmented frame (PsF) video to progressive video automatically if Setup Menu option
[Video - File Resolution/Rate] is set to a progressive frame format (for example 1080p30). If Setup
Menu option [Video - File Resolution/Rate] is set to interlaced format (for example 1080PsF30), the
PIX 250i will record PsF signal unaltered, but the file will be stamped as interlaced.
Frame rate conversion occurs whenever the frame rate of [Video - File Resolution/Rate] differs
from the frame rate of the input video signal. Frame rate conversion is achieved by appropriately
duplicating or dropping frames. The PIX 250i will auto-sense between integer and non-integer frame
rates (for instance 30 frames vs. 29.97 frames). The PIX 250i will not frame rate convert between
integer and non-integer frame rate values. For example, if the incoming video signal is 1080i59.94,
it can be converted to 1080p29.97 or 720p59.94 but not 1080p30 or 720p60. The Setup Menu option
[Video - File Resolution/Rate] contains entries with a combination of integer and non-integer frame
rates (such as 1080p30/29.97). When any of these options are selected, the PIX 250i will record in the
indicated integer frame rate if the input video is an integer frame or record in the indicated non-integer frame rate if the input video is a non-integer frame rate.
Not all frame rate conversions are visually desirable. When the OSD Item File Resolution/Rate is
red, the conversion of the frame rate of the input video will contain a finite amount of motion judder.
For example, if the incoming video is 720p60 and [Video - File Resolution/Rate] is set to 720p50,
the cadence of dropped frames may be noticeable depending on the content. Conversions which are
simply 1:2 or 2:1 (such as 1080i59.94 to 1080p29.97) introduce no motion judder. For these conversions, the OSD Item File Resolution/Rate remains white.
When the input video signal is 720p24 or 720p23.976, up-, down-, and cross-conversion is not available.
3:2 Pulldown Removal
Many cameras which shoot with a shutter speed of 24/23.976 frames per second will output signal
on the HDMI or SDI output at 60i/59.94i. To achieve this, the camera performs a “3:2 pulldown”
process. The 3:2 pulldown process splits each frame into 2 fields and duplicates a field periodically.
The PIX 250i is capable of removing 3:2 pulldown from a 60i/59.94i signal and converting it back to
24/23.976 progressive frames per second in real-time. The PIX 3:2 removal process actively views
video fields looking for duplicates. When these duplicates are sensed, then this cadence is locked in
and the appropriate extra fields are removed. The process depends on motion in the incoming video.
The OSD item File Resolution/Rate changes from orange to white when this cadence is detected:
25
PIX 250i User Guide and Technical Information
Orange: No 3:2 pulldown sensed in 60i/59.94i input signal.
Input video is being converted to 24p/23.976p using a conversion process which drops frames and may introduce judder.
White: 3:2 pulldown sensed in 60i/59.94i input video signal.
Input video signal is being converted to 24p/23.976p using 3:2
pulldown removal which recreates 24p/23.976p as it is captured from the camera’s shutter.
It is important that 3:2 pulldown be sensed before beginning a recording. If recording begins before 3:2
pulldown is sensed, 3:2 pulldown will not be applied properly.
Video Scaling & Frame Rate Conversion
Up and Down Conversion
Standard-definition video resolution employs a 4:3 aspect ratio, and high-definition video resolution
employs a 16:9 aspect ratio. Up-conversion is the process of fitting standard-definition video (with a
4:3 aspect ratio) into a high-definition, 16:9 frame. Down-conversion is the opposite process.
The PIX 250i has various options for up and down conversion:
Down-Conversion
Letterbox: Maintains the same height and width ratio. Results in blank bar at top and bottom of image.
Crop: Left and right side of image is cropped to fit into 4:3. Results in missing image at sides of picture.
Anamorphic: Image is horizontally squashed to fit into 4:3. Results in a narrow looking image.

Playback
The PIX 250i has a very powerful playback engine that allows for playback of QuickTime .mov files
whether generated by the PIX 250i or elsewhere (See “Appendix A - Supported Files”, page 71). Playback video is shown on the onboard LCD display and is sent to the video outputs. The PIX 250i’s
video playback clock is determined by the setting in [Timecode/Sync - Sync Ref - Video Playback].
Any number of PIX 250i units can be assigned to one of four available network groups for grouped
record and playback of video on multiple units simultaneously (See “Network Grouping”, page 40).
Playback Operation
The current Playback drive is indicated by the green Drive Status OSD field. From the Main View,
pressing the Play () button after a recording will play the most recent file. Using the Rewind (<<)
and Fast Forward (>>) buttons, previous recorded files can also be cued for playback. The file cued
up for Playback is displayed in the File Name field of the OSD.
To browse files on the Playback drive, press the FILES button. This will display the File List of the
current Playback drive. Pressing Play () in the File List will play the currently highlighted file.
Playback
To browse files on another drive, scroll beyond the top of the File List to access the drive selection
list. When a file is played, the drive it is played from will become the current Playback drive. When
a new take is recorded, the lowest numbered drive it is written to will become the current Playback
drive.
In Playback Mode the Play () button and the OSD Items ABS Time, Timecode, and Filename are
green. While in Playback Mode, pause playback by pressing the Play () button again. The Play button flashes green to indicate playback is paused. Press the Stop () button any time to stop playback
and exit Playback Mode.
Frame by frame scrolling (similar to the traditional Jog function) is supported when playing back
QuickTime .mov files. To scroll through a video file frame by frame, pause playback then turn the
Control Knob to increase/decrease the video file in one frame increments.
Various looping playback functions are supported. A single file or a section of a file (defined by cue
markers) can be continuously looped by entering Looping Playback Mode (See “Looping Playback”,
page 34). Additionally, a list of files can be defined as a Play List and the Play List can be looped
(See “Play List”, page 35).
Playback audio is routed to audio outputs as determined by output routing options in the [Audio]
Setup Menu section. (See “Audio Outputs”, page 14)
Fast Forward and Rewind
Hold down the Fast Forward (>>) or Rewind (<<) button during playback for 2x (double) speed
playback. When the Fast Forward (>>) or Rewind (<<) button is held for five seconds or more the
playback will become 16x speed. Normal playback will resume when the buttons are released.

PIX 250i User Guide and Technical Information
Synchronization and Timecode
Synchronization of video, audio, and associated timecode while recording video and audio has long
been a problematic area. Situations where several cameras are used can complicate issues further.
There may be sync issues between two (or more) cameras and/or between audio recorders because
of a) offset and b) drift. In a production environment (during recording), offset and drift are both
terms to describe a timing problem between the timecode signal from two or more audio or video recorders. In a post-production environment (a non-linear editor application), offset and drift are both
terms to describe a timing problem between two or more audio or video files.
Synchronization & Timecode
Offset (matching the beginning or “head” of a take) occurs because the beginning of takes are not
aligned due to the absence or misuse of timecode. Drift (matching the end or “tail” of a take) occurs
because different recorders (audio or camera) run at different rates - the beginning of files from each
may have zero offset, but by the end they drift apart. The PIX 250i was designed with these problems
in mind and includes the most comprehensive and powerful synchronization features available in a
production recorder. These features can be used to alleviate or eliminate offset and drift problems in
both production and post-production. While the PIX 250i’s design makes setting the parameters as
easy as possible, a good understanding of synchronization is still necessary to properly operate the
PIX 250i and ensure a trouble-free workflow.
In a camera, the shutter, video circuitry, audio sampling, and timecode all run off of one “heartbeat”
from its master internal clock. If this master clock is slightly fast, then the shutter, audio sampling,
and timecode will be slightly fast. If the master clock is a slightly slow, the shutter etc will also be
slightly slow.
When a PIX 250i’s video input is connected via HDMI or SDI to a camera or other video source,
this “heartbeat” is passed through the HDMI or SDI. The PIX 250i video and audio circuitry can be
clocked off of this incoming signal. In other words, the PIX 250i references this clock and synchronizes its own clock to it. The PIX 250i writes files based on this clock as well - each audio sample and
video frame written out to the file is synchronized to the incoming video. This way, the PIX 250i is
always completely in sync with the connected video source - there can never be any drift of audio or
video between the camera and the PIX. (See “Sync Reference”, page 34)
Drift problems in a workflow can arise when more than one camera is used on a shoot, as each camera is driven off of its own internal master clock. Since internal master clock speed will always vary
from camera to camera (and vary based on temperature and time), each camera used will run at a
slightly different shutter speed, audio sample rate, and timecode rate. This is also true when recording video on a camera and recording audio on a separate recorder, as each device has its own internal master clock. Particularly problematic are long takes where there may be significant drift from
camera to camera from the beginning to the end of the take’s file. Even if the heads match, the tails of
a take may not.
These drift problems can be mitigated during recording by using a Genlock (or “Sync”) Input on a
camera which takes over the camera’s internal master clock. Wiring several cameras’ Genlock Inputs
together forces all of the cameras to run at the exact same rate with no drift. This same concept applies to audio recorders using the Word Clock input. Genlock inputs are available only on higher-end
cameras and Word Clock inputs are available on higher-end audio recorders.
Offset problems are easier to overcome than drift problems. By feeding each recording device with
the same timecode signal, the files from different recording devices can all be in sync and there will
be no offset in post-production.
The PIX 250i can address the synchronization issues of both offset and drift (heads and tails) via its
built-in Ambient® Lockit with Genlock Out and Timecode Reader. The PIX 250i’s Ambient® Lockit
33
PIX 250i User Guide and Technical Information
features an internal clock which has an accuracy of +/-0.2ppm (½ frame per 24 hours). Numerous
PIX 250i recorders can be used to maintain extremely tight synchronization.

By default, the currently referenced synchronization source is always displayed on the OSD preceded by Sync:. When valid signal is present at the selected source, the OSD label will be displayed
in white text. When no valid signal is present at the selected source, the OSD label will flash and the
text will be red.
Synchronization & Timecode
Video Playback Synchronization
Setup Menu option [Timecode/Sync - Sync Ref - Video Playback].
The PIX 250i’s sync source is always the incoming video signal when stopped and while recording.
This is to ensure that the PIX 250i is always in sync with the incoming video source. During Playback
of QuickTime files, the PIX 250i can reference its own Internal clock, Video Input (SDI/HDMI), or
Genlock signal at the SYNC IN BNC.
When [Timecode/Sync - Sync Ref - Video Playback] is set to Video Ref (Sync In), and no valid signal
is present at the SYNC IN connector when playback is initiated, a warning dialog will appear on the
LCD.
When [Timecode/Sync - Sync Ref - Video Playback] is set to Video Input (SDI/HDMI), and the playback file’s resolution and rate are different than the Video Input, the PIX 250i will automatically use
its Internal clock. The OSD label will flash with red text during playback to indicate this.
Timecode Reader
The PIX 250i includes a timecode reader which can accept incoming SMPTE timecode. The
PIX 250i can read timecode from embedded SDI / HDMI or linear timecode fed into the
TC IN BNC connector. The timecode reader is enabled whenever the Setup Menu option
[Timecode/Sync - Timecode Mode] is set to any Ext TC mode which indicates that it will read external timecode.
Timecode Reader operation is useful for simple cases where the PIX 250i’s timecode follows the
camera timecode. The timecode of the PIX 250i’s file will match exactly with the camera’s file with
zero-drift since the PIX 250i is always synchronized with video input during recording (See “Video
Playback Synchronization”, page 34).
In situations where a consistent offset is observed between PIX 250i files and other production recordings, the PIX 250i can offset the timecode stamp on each file. The Setup Menu option
[Timecode/Sync - File Start TC Offset] allows for adjustment of the frame offset from -10 to +10 in
increments of 1 frame. This setting does not affect timecode on the PIX 250i’s outputs.
For shoots involving more than one camera or an audio recorder, using the PIX 250i’s Timecode Generator can be more beneficial than using the Timecode Reader to achieve good heads and tails sync
between all recordings.

PIX 250i User Guide and Technical Information
Internal Ambient® Lockit: Timecode Generator with Sync Out
The PIX 250i includes an internal Ambient® ACL-203 Lockit which can be used as a master sync/
timecode source for cameras or audio recorders. The Lockit is an ultra-high accuracy sync/timecode
generator with < 0.2 ppm (½ frame per 24 hours) accuracy that is suitable as a master clock in all
levels of productions. With its internal, rechargeable battery, accurate timecode is maintained for up
to 4 hours after the PIX 250i is powered down. After 4 hours, the timecode value is reset. The battery
is recharged automatically.
Multi-camera shoots using cameras that accept genlock input can benefit from the PIX 250i’s built in
Ambient® Lockit as their master sync and timecode source. Files from multiple PIX 250i recorders
will have very tightly synchronized recordings with matching heads and tails.
Additionally, even multi-camera shoots utilizing lower-cost cameras (with no genlock or timecode)
can benefit from the built-in Lockit. By using the Timecode Generator to stamp the beginning of each
file, the heads of each take will match from several recorders, even if the tails drift due to using nongenlocked cameras.
Setting the Sync Out
Synchronization & Timecode
The setting of this is parameter is found in Setup Menu option [Timecode/Sync - Sync Out]. When
the Sync Out of the PIX 250i is not needed, set this option to Off. When using the Lockit to generate the Sync (genlock) for a camera, the frame rate and resolution must be set for the camera’s sync
input. Consult the camera’s documentation for information of which rates are accepted.
Additionally, there are two advanced modes under [Timecode/Sync - Sync Out]:
Genlock, Follows Video In and Wordclock, Follows Video In. Genlock, Follows Video In can be
used to slave another camera’s or audio recorder’s genlock input to the camera feeding the PIX.
Likewise, Wordclock, Follows Video In can be used to slave an external audio recorder to the camera
driving the PIX to achieve perfect audio sync with zero drift. Drift is less likely to be an issue when
recordings are kept short.
Sync out is an output of the unit’s many internal sync generation capabilities. It is not possible to pass
the Sync Input signal to the Sync Output (this is not a loopthrough).
Timecode Modes
Freerun Timceode Mode
Generator mode. Timecode runs continuously. The value can be set by “jamming value” in the Setup
Menu option [Timecode/Sync - Jam Received TC] or by manually setting a value from the Setup
Menu option [Timecode/Sync - Set Generator TC].
Freerun Auto Mute
Functions the same as Freerun mode except timecode signal is muted from the timeocde output
when the PIX 250i is in stopped mode. This allows rec-run functionality when Rec Run mode is not
suitable (e.g. Multi-camera shoots).
Record Run Timecode Mode
Generator mode. The PIX 250i sends running timecode while recording and stationary timecode
while not recording. Timecode in this mode defaults to the last stationary value at power-up. When
switching to record run from another mode, the internal generator will stop at the last number gen-
35
PIX 250i User Guide and Technical Information
erated. A user-defined value can be jammed into the internal generator from the Setup Menu option
[Timecode/Sync - Set Generator TC].
24 Hour Run Timecode Mode
Generator mode. Time code runs continuously. When this Time Code Mode is selected or when the
time/date is altered, the time code value is jammed to the value of the time-of-day clock. The value
can be set by “jamming value” in the Setup Menu options [TIMECODE/SYNC - Jam Received TC] or
[TIMECODE/SYNC - Jam Time Of Day]. The value can also be set manually from Setup Menu option
[TIMECODE/SYNC - Set Generator TC].
24h Run Auto Mute
Functions the same as 24h Run mode except timecode signal is muted from the timeocde output
when the PIX 250i is in stopped mode. This allows rec-run functionality when Rec Run mode is not
suitable (e.g. Multi-camera shoots).
External Timecode Mode
Synchronization & Timecode
Reader mode. The PIX 250i’s internal timecode generator follows an external timecode signal appearing at the BNC Timecode Input, timecode embedded on the SDI or HDMI input (See “SDI or
HDMI Input Embedded Timecode”, page 36). If the external timecode is removed the internal generator continues to run to preserve continuous timecode.
Timecode Frame Rate
In External mode, if the incoming frame rate does not match the frame rate as set in
Video - File Resolution/Rate, the timecode frame rate display will appear orange to notify the user.
The PIX will still record using the File Resolution/Rate.
Timecode Input Sources
Timecode BNC
The Timecode Input BNC accepts standard SMPTE timecode signal.
SDI or HDMI Input Embedded Timecode
The PIX 250i can use timecode embedded in the SDI or HDMI input signal.
[Timecode/Sync - Timecode Mode] must be set to Ext TC (SDI, HDMI).
Synchronization/Timecode Examples
The following examples illustrate common scenarios where timecode and synchronization can be
employed with the PIX 250i and other devices.

PIX 250i User Guide and Technical Information
In this scenario, the video camera is the master source of the video sync. The timecode can either be
read from the camera or be generated by the PIX 250i. The accuracy of the recording is dependent on
the internal clock accuracy of the camera.
To receive timecode from the camera, set [Timecode/Sync - Timecode Mode] to Ext TC (LTC) for
cameras that output standard SMPTE timecode to the PIX 250i’s Timecode BNC. Alternatively, the
PIX 250i can receive timecode from the SDI or HDMI input (if the camera sends timecode in this
way) by setting [Timecode/Sync - Timecode Mode] to Ext TC (SDI, HDMI).
The Setup Menu option [Timecode/Sync - Sync Out] can be set to several valid settings, including
the following:
• Off - sync signal is disabled.
• Genlock, Follows Video In - Genlock for another camera or device is derived from the video signal of the single camera.
• Wordclock, Follows Video In - Wordclock for an audio device is derived from the video signal of
the single camera.

In this scenario, a PIX 250i is the master sync source for multiple cameras , each with or without their
own PIX acting as a recorder. Because of this locked connection, the cameras can be run indefinitely
and be assured of frame-accurate sync with no possibility of drift.
Set the output of the sync generator to a selected rate and connect the PIX 250i Sync Out (Genlock)
and timecode output to multiple cameras (“mult” the genlock output). This connection uses the PIX
250i as both the video sync source and timecode source. Heads and tails sync for the camera’s and
PIX files will be perfect.

PIX 250i User Guide and Technical Information
Powering
Powering
The PIX 250i features an advanced powering system with PowerSafe technology. By default, the PIX
250i will operate from the DC power source. When the DC power source is removed, PowerSafe
circuitry will activate. The PIX 250i will display a warning, stop any active recordings, finish writing
files, and shut the PIX 250i down. The PowerSafe Battery will power the PIX 250i during this time.
This feature ensures that files will be protected even in the event of unexpected power loss.

PIX 250i User Guide and Technical Information
Network Grouping
When multiple rack-mounted PIX video recorders (PIX 250i, PIX 260i, or PIX 270i) or the 970 Audio
Recorder are in use on an Ethernet network, they can be grouped together for transport control and
linking of most setup options. Setup Menu option [Network - Network Group] assigns the PIX 250i
to one of four available groups.
In this section, the term “unit” refers to PIX 250i, PIX 260i, or PIX 270i Video Recorders, or the 970
Audio Recorder.
There is no “master” / “slave” relationship in Network Groups. All units in a group are “master”.
Transport commands and settings changes made on any unit a group will ripple to all other units
in the group. If a transport command or settings change has to be made to only one unit in a group,
the unit must be temporarily removed from the group before making the change. To quickly toggle
between No Group and the current group setting, press MENU button + Control Knob.
Requirements and considerations when setting up Network Groups:
Network Grouping
• The maximum number of units supported in a single group is currently 10. Increasing the amount
of units in a group increases the time of response for grouped transport commands and auto-configuration.
• It is recommended that timecode be distributed individually to each unit in a group rather than
“daisy-chained” through units in a group.
• Allow all units in a group to auto-configure before proceeding with grouped operations. See the
following section for details. (See “Group Auto-Configuration”, page 40)
• Some settings are not linked even when units are in a group together. (See “Grouped Settings”, page
41)
Group Auto-Configuration
When changes are made to a Network Group, all units in the group must auto-configure. It is important to allow all units in the group to complete auto-configuration before proceeding with any
grouped operations (Transport control, settings changes, etc). While configuring, units will display
a dialog message: Configuring Network: Please Wait... Wait 10 seconds after this dialog has cleared
before proceeding with grouped operations.
Common tasks that will cause a group to auto-reconfigure:
• A unit on the LAN is powered on or off.
• A unit is connected or disconnected from the LAN.
• A unit is added or removed from a group via [Network - Network Group].
Grouped Transport
Transport control (Record, Play, Pause, Stop, Jog, Shuttle, Fast Forward, and Rew) of grouped units
is linked. Recording and playback is frame-synchronized among PIX 260i and PIX 270i units in a
group. When a file is selected for playback, all units in the group will play the file of that same name
if it exists. If no file of that name exists, grouped units will play the most recently played or recorded
file.

PIX 250i User Guide and Technical Information
Adding and removing cue markers, jumping to cue markers, and looped playback is not supported
in grouped units. These features can be effectively used in a grouped unit setup; However, manual
setup on each unit in the group is required. Following are step-by-step instructions to using these
features with grouped units. Failure to comply with these recommendations can result in undesired
behavior if any one of these features is in use while units are grouped. This could include:
• Out-of-sync playback between grouped units
• Some units in the group dropping out of playback prematurely
• Some units playing back the wrong file
• Sluggish transport control response time
To effectively use Loop Play Mode with grouped units:
1. Press and hold Play until the OSD reads LOOP.
2. Repeat step 1 on all units in the group. Now when a clip is looped, the units will remain in
sync.
To effectively use Cue Markers with grouped units:
1. Playback a file.
2. Find the spot in the file in which a cue marker is to be placed.
Network Grouping
3. Pause Playback.
4. Press FILES + Fast Forward to lay a cue marker.
5. Repeat step 4 for all units in the group. Now when jumping to a cue marker on one unit all
units in the group will also jump to the cue point and remain in sync.
To loop between cue points on grouped units:
1. With Loop Mode on and Cue Markers all set, locate the cue point in which the loop will
begin.
2. Press Play + Fast Forward to change the Loop behavior from Loop Clip to Loop Segment
mode. The OSD will display the loop points (for example Cue 1 - Cue 2).
3. Repeat step 2 on all units in the group. All units in the group will now loop between the
selected cue points and remain in sync.
Grouped Settings
A settings change of any unit in the group will be rippled through to all other units in the group,
with some exceptions. The following settings and functions will always apply only to the unit that
they are made on, and not ripple through to other units in the group:
• All [Network] options.
• All [Quick Setup] options.
• [File Storage - Erase/Re-format]
• [Timecode/Sync - Timecode Mode]
• [Timecode/Sync - Jam Received TC]
• [Timecode/Sync - Jam Time of Day]
• [Timecode/Sync - Set Generator TC]
• [Timecode/Sync - Set Generator UBits]
• [System - Set Date/Time]

Triggering Recording from External Timecode
External Control
The PIX 250i can be configured to start recordings when incoming timecode begins rolling and stop
when it becomes stationary. This is generally referred to as Record Run timecode. The master timecode device should be setup in this manner. To configure the PIX 250i to follow Record Run commands:
1. Set Setup Menu option [Remote Control - Rec Start/Stop] to Timecode
2. Make sure that the device that is sending timecode is configured to send stationary timecode
while stopped and running timecode while recording.
3. Some cameras do not send the correct timecode in the first few seconds of a recording, or
they send short bursts of timecode causing the PIX 250i to record short unintentional files.
The [Timecode/Sync - Auto Record Hold Off] feature is designed to eliminate these issues.
When a hold off value is applied, the PIX 250i will begin capturing the moment timecode
begins rolling but will only go into record if a valid timecode signal is present after the hold
off time has elapsed.
Triggering from external timecode will not cause the PIX 250i to automatically stamp external timecode to recorded files. The timecode stamped to files is determined by the setting
[Timecode/Sync - Timecode Mode]
Triggering Recording from SDI Flag Bits
Start and stop flags embedded in the SDI signal from some cameras can be used to
start and stop recording of the PIX 250i. To enable this feature, set Setup Menu option
[Remote Control - Rec Start/Stop] to the SDI Flag option that refers to the manufacturer of the connected camera.

PIX 250i User Guide and Technical Information
Storage and File Management
Storage
The PIX 250i records on up to two separate storage devices simultaneously. There are two PIX-CADDY slots on the front panel which are accessed by pulling the LCD Handle forward and tilting the
LCD down.
PIX-CADDY
Drives 1 and 2 are PIX-CADDY slots behind the LCD on the Front panel.
Storage & File Management
The PIX-CADDY allows for simple, quick, and solid connection and removal of drives for file storage and exchange. When connected to a PIX 250i, whether powered on or off, the caddy’s USB 3.0,
FireWire 800 connections are disabled. When the PIX-CADDY is removed from a PIX 250i, it operates
as a high-speed data interface for transferring files from the drive to a computer. Only one data connection can be used at a time. See PIX-CADDY documentation for details on attaching a 2.5” drive to
the PIX-CADDY.
Supported Storage Devices
Sound Devices maintains a list of storage devices that are approved for use with the PIX 250i. An upto-date list of supported storage devices can be found online: http://www.sounddevices.com/approved
Approved mechanical drives are recommended for use only in stationary applications. Excessive vibration
or motion may cause data corruption when using mechanical drives.
The PIX 250i formats and writes to a exFAT filesystem. The ExFAT filesystem is readable and writable by Mac OS X, Windows 8, Windows 7, and Windows Vista. Files stored in a ExFAT filesystem
are not restricted to 4GB, unlike FAT32 (a commonly utilized filesystem in other digital recorders).
Storage devices to be used with the PIX 250i must be formatted by the PIX 250i.
Drives formatted to UDF with earlier versions of PIX 250i firmware or PIX 220i and PIX 240i recorders
can still be used in the current PIX 250i.
Windows XP is not compatible with exFAT volumes by default. The Microsoft update KB955704
(http://www.microsoft.com/en-us/download/details.aspx?id=19364) will allow Windows XP to read and
write to exFAT volumes.
Mac OSX 10.6.4 and below does not support exFAT volumes.
Formatting
To format a drive:
1. Make sure the drive to be formatted is connected to the recorder and note which drive number it is.
2. Open Setup Menu option [File Storage - Erase/Re-format].
51
PIX 250i User Guide and Technical Information
3. Choose the Erase/Re-format: Drive Number for the drive to be formatted or
Erase/Re-format: All Drives option.
4. A confirmation dialog will appear: “All data will be erased. Continue?”. Use the Control
Knob to select OK.
5. Use the displayed on-screen keyboard (or an external USB keyboard, if attached) to enter a
volume label for the drive, and then use the Control Knob to select OK to initiate the format.
When formatting all drives at once, the volume label is applied to all drives but each drive
will be suffixed with an underscore and drive number to distinguish between drives.
Drive formatting can alternatively be initiated from PIXNET under the File Storage menu.
Drive Modes
Each of the four drive slots can be set to Off, Record,
Ethernet File Transfer, or Switch to Network upon Full from the Setup Menu option
[File Storage - Drive Record/Network Mode].
Storage & File Management
• Off: Drives attached to this drive slot will not be written to during recording. Any compatible
files on the drive will still be available for playback and the drive can still be formatted.
• Record: Drives attached to this drive slot will be written to for recording. This is the default
mode.
• Ethernet File Transfer: Drives attached to this slot will be shared to the network as a standard
Samba share (see Ethernet File Transfer) and cannot be recorded to, accessed for playback from
the PIX 250i, or formatted.
• Switch to Network upon Full: Drives attached to this slot will be in Record mode until they are
filled. Once filled, they will be Ethernet File Transfer mode.
When [File Storage - Record Mode] is set to Simultaneous, a drive that becomes full will only
mount as a network share when the last drive that is set to Switch to Network upon Full becomes full.
Record Mode (Simultaneous or Sequential)
The Setup Menu option [File Storage - Record Mode] determines how drives will be written to during recording. When set to Simultaneous (the default setting), all drives that are online and set to

PIX 250i User Guide and Technical Information
Metadata
Several parameters can be set within the Setup Menu File Storage to aid in the organization of files.
Some of this metadata can be used in naming the file which is to be recorded. Folders are created on
the drives based on the Reel number. QuickTime files contain reel and timecode metadata.
CamID
The CamID field consists of a single alpha character. It is intended to indicate which physical camera
shot the content for the take.
Reel
The reel can be considered a container for all assets generated during a recording session or day’s work. It is intended
to indicate what reel the recording is part of. The PIX 250i
will create a folder at the root level for each Reel. Recorded
files are placed inside the current Reel folder.
Storage & File Management
Clip
The Clip field consists of a numeric value between 1 and
999. It is intended to indicate what clip number the recording is. This field can be set manually and will increment each time a new file is recorded. The Clip
number will reset to 1 when the Reel number is changed.
Scene/Shot
The Scene/Shot field consists of a alpha-numeric value. Use this field to indicate a descriptive name
for the current scene or shot.
To quickly increment the Scene/Shot value, press Stop + Fast Forward from the
Main View. How the Scene/Shot value increments depends on the current setting of
[File Storage - Scene Increment Mode]:
Numeric: If the current Scene/Shot value does not have a number on the end, the number 1 will be
appended. Otherwise, the last number will be incremented by 1.
Character: If the current Scene/Shot value does not have a alpha character on the end, the letter “A”
will be appended. Otherwise, the last letter will be incremented alphabetically. If the final character
is “Z” it will be changed to “A” and - if a alpha character precedes it - that character preceding will
be incremented alphabetically; Otherwise a preceding “A” will be added so that the resulting Scene/
Shot value ends in “AA”.
Off: Scene Increment shortcut will have not effect.
Take
The Take field consists of a numeric value between 1 and 999. It is intended to indicate what take
number the clip is, relative to the scene. This field can be set manually and will increment each time
a new file is recorded. The Take number will reset to 1 when the Scene name is changed.
File Management
The PIX 250i provides several tools for file management and metadata entry. File management of
files to be recorded is managed in File Storage. File management for files previously recorded material is handled in the File List. See File List and File Details for navigation and basic overview.
53
PIX 250i User Guide and Technical Information
File Size Limit
To aid in maintaining manageable file sizes, the PIX 250i will automatically begin writing a new file
after a set amount of minutes has elapsed in a recording. The beginning of this new file will be seamless to the ending of the previous file. File splitting is disabled by default. The Setup Menu option
[File Storage - QuickTime File Split every] adjusts the amount of time before a file split occurs. File
split options include 1, 5, 10, or 15-minute splits.
QuickTime file splitting must be used when [File Storage - Record Mode] is set to Sequential. If
[File Storage - Record Mode] is set to Sequential, the Split Disabled setting of Setup Menu option
[File Storage - QuickTime File Split Every] cannot be used.
When [File Storage - QuickTime File Split every] is set to Split Disabled, manual file splitting with
the REC button is also disabled (Even when [System - Rec button file Split] is set to On).
File Naming
Storage & File Management
Files are named according to the file name format as set with Setup Menu option
[File Storage - File Name Format]. The options for file name format include various combinations of
CamID, Reel, Clip, Scene/Shot, and Take metadata fields. The file name format can also be prefixed
with the PIX Name as defined in [Network - This PIX’s Name]. To prefix the file name with the PIX
name, set [File Storage - File Name Prefix] to PIX Name.
RED File Format
When the Setup Menu option File Storage - File Name Format is set to RED File Format, the PIX
250i will
• Generate files that follow the same naming convention used by RED cameras.
• Extract the CamID, Reel number, and Clip number from the SDI input signal from a RED One or
RED Epic camera and apply it to the file name and appropriate metadata fields of each recorded
file. (See “Metadata”, page 53)

Transferring Files
USB, Firewire, Thunderbolt
Files on PIX 250i formatted storage volumes (approved 2.5” drive or external storage device) can be
copied to a computer by removing the storage device from the PIX 250i and connecting it to a computer. Storage devices formatted with the PIX 250i recorder use the ExFAT filesystem. See File Storage
The Firewire 800 and USB 3.0 connectors on the PIX-CADDY are disabled when the PIX-CADDY is
attached to the PIX 250i. When attaching the PIX-CADDY to a computer, either the Firewire 800 or
the USB 3.0 connection must be used; not both.
Sound Devices recommends first copying files from the drive to the computer and then editing the
files. It is not recommended to edit files directly off of the drive.
Do not copy unsupported files from a computer (or any other host device) to a drive that is intended to be
used by the PIX 250i. If this occurs, it is advisable to format the drive with the PIX 250i before making
new recordings. See Appendix A for currently supported files
Ethernet File Transfer (Samba)
Samba is an industry standard networking protocol that enables files to be transferred between
the PIX 250i and any device with access to the network (A computer running Mac OSX, Windows,
or Linux for example). Ethernet File Transfer can be initiated remotely via PIXNET (web browser
interface). Ethernet supports data rates up to a theoretical maximum of 1Gbps. In reality, data transfer speeds over Ethernet are dependent on network traffic and many other factors. To transfer files
between the PIX 250i and another network device:
1. Attach an Ethernet cable from either PIX 250i Ethernet port to a computer or a LAN (Local
Area Network) connection.
2. Enter Setup Menu [File Storage - Drive Record/Network Mode] to access the Record/Network mode menu for all drives.
55
PIX 250i User Guide and Technical Information
3. Select the drive to be mounted and set its mode to Ethernet File Transfer. This drive is now
attached to the Network and unavailable to the PIX 250i for read or write actions. The Drive
