PIX 250i User Guide

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. 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.

This User Guide details installation and operation of the PIX 250i. This User Guide corresponds to
PIX 250i firmware version 2.10. 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, etc).

All physical button names are detailed in the Panel Descriptions section.

• Button combinations are represented with the plus (+) symbol. For example: “Press LCD + AU­DIO” means to first hold down LCD, then press AUDIO, 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 MENU is pushed, and the parameter is an
item in the list displayed when that category is selected (by pressing 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.

Inputs and Outputs

Video Inputs

The PIX 250i accepts video input signals over HDMI, HD-SDI, and single link 3G-SDI Level A and B.

The PIX 250i does not accept analog video signals. See the Specifications section for a complete list of
supported frame rates.

HDMI

The PIX 250i accepts HDMI version 1.4a video and audio. Supported video resolutions and rates are
listed in the Specifications section. The PIX 250i HDMI input accepts up to 10-bit, 4:4:4 video, up to 8
channels of embedded audio. The PIX 250i also accepts Sony’s proprietary timecode over HDMI. The
digital audio embedded in the HDMI stream (32 kHz – 192 kHz) is always re-sampled to 48 kHz.

720p30/29.97, 720p25, and 720p24/23.976 are not supported on the HDMI input or the HDMI output.

Inputs & Outputs

HDCP copy protection prevents direct digital-to-digital copying of copyrighted material. Protected
DVDs, Blu-Rays, and streaming content with HDCP encryption is not valid content and will be ignored
by the PIX 250i.

SDI

The SDI input on the PIX 250i accepts video with embedded audio (up to 16 channels) and embed­ded SMPTE timecode. This connection accepts digital video up to 12-bit, with up to 4:4:4 color sam­pling. Unlike the HDMI interface, which auto-negotiates rates between devices, what comes out of a
camera’s SDI output is received by the PIX 250i with no auto-negotiation or sample rate conversion.

The PIX 250i supports 3G-SDI single link, but not dual-link HD-SDI.

Timecode over SDI is not available when recording in standard definition

Video Outputs

Both HDMI and SDI outputs are active simultaneously. This allows for conversion from SDI to
HDMI and HDMI to SDI.

The output video signal source is the signal present at the currently selected video input (Setup
Menu option [Video - Video Input]), except during video playback. The resolution and frame rate of
the output stream is determined by the Setup Menu option [Video - File Resolution/Rate] setting,
except during video playback. The SDI Output is capable of sending HD (4:2:2 10-bit) or 3G (4:4:4
12-bit), this is set in [Video - SDI Output Type].Video playback signal is sent to the HDMI and SDI
Outputs.

Ethernet

The PRI and SEC Ethernet ports on the rear panel of the PIX 250i are used for a variety of PIX 250i
functions/features:

• Network Grouping (See “Network Grouping”, page 41)

• File Transfer (Samba) (See “Transferring Files”, page 57)

• Web Browser Control (See “Web Interface - PIXNET”, page 44)

Up to four PIX 250i units can be daisy-chained using their built-in Ethernet switches. If using five or
more PIX 250i units, Sound Devices recommends using an external Ethernet Switch in a star configu­ration.

The PIX 250i can either be allocated an IP address from a DHCP server (recommended) or over Link­local networking. Link-local networking is a protocol which automatically allocates a 169.254.x.x IP
address in the absence of any DHCP server. If a DHCP server is available, the PIX 250i will automati­cally use it if [Network - Auto IP Settings] is set to On.

Alternatively, the IP address can be configured manually. When Setup Menu option
[Network - Auto IP Settings] is set to Off, Setup Menu options [Network - IP Address],
[Network - Subnet Mask], and [Network - Gateway] are enabled. When these settings are improp-

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 - Video 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 41).

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”, page 50) (See

“Synchronization and Timecode”, page 39)

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/

The Setup Menu is not accessible during recording and playback. The File List is not accessible dur­ing Playback.

Sound Devices File Format

During recording the PIX 250i writes to a temporary file format. Files are written with the extension
.SDV. When recording is stopped, the file is “finalized” to a standard Quicktime (.mov extension).
The Sound Devices file format allows for reliable recovery of content in situations where power was
lost or a drive was removed during recording. Upon powering up, the PIX 250i will search for any

.SDV files can also be recovered to .MOV files on a Windows computer using the FileSafe utility. (See

“FileSafe Utility and the Sound Devices File Format”, page 58)

File Splitting

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. When a split occurs, a new file will be created and grouped with the other files from
the clip in the File View. (See “Storage and File Management”, page 59)

Audio tracks on video files will not split seamlessly. Some small, brief clicks may occur on some audio
tracks in split video files. The video content of video files will always split seamlessly.

False Take

To discard the last take and delete the file (False take), press Stop () button + Rewind (<<) button. A
dialog box will appear warning that the last take will be deleted and indicate the file name. Use the
Control Knob to highlight OK and press the Control Knob to confirm.

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
signals, except during playback. The PIX 250i can record QuickTime files in the following resolutions
and frame rates:

• 1080 p 30

PIX 250i User Guide

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).

Recording

ProRes is a variable data rate codec and DNxHD is a fixed data rate codec. PIX 250i supports all
compression levels and bit rates of ProRes and DNxHD 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.

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.

24

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.

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 a clapper slate on a test file for
each camera resolution/frame rate to be used on a project before starting. See Audio Input Delay Con-

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 AUDIO 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 high-

lighter 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 is selected).

Changing a track’s Input Source to Off will disarm the track.

PIX 250i User Guide

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 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

Video Scaling & Frame Rate Conversion

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 rate or record in the indicated non­integer 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 that 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:

26

v. 2.10 Features and specifications are subject to change. Visit www.sounddevices.com for the latest documentation.

PIX 250i User Guide

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.

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.

PIX 250i User Guide

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 73). 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 41).

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, previously 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 FILES. This will display the File List of the current Play­back drive. Pressing Play () in the File List will play the currently highlighted file.

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, Filename and
Drive Indicator 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. In Video Mode, 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 36). Additionally, a list of files can be defined as a Play List and the Play

List can also be looped (See “Play List”, page 37).

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.

File Skip

From Stopped Mode, press Fast Forward (>>) to skip to the next file on the current Playback drive.
Press Rewind (<<) to skip to the previous file on the current Playback drive.

Playback

During Playback, press Fast Forward (>>) to jump to the next Cue Marker (if applicable) or begin
playback of the next clip (if it exists). Press Rewind (<<) to jump to the previous Cue Marker (if ap­plicable) or to the beginning of the current file. Immediately press Rewind (<<) again to skip to the

29

previous file’s last Cue Marker (if applicable) or beginning. File Skip functions will work while a clip
is playing and while it is paused.

Shuttle Playback Mode

In Shuttle Playback Mode the PIX 250i is capable of playing back at various rates in forward and in
reverse. Shuttle Playback Mode is only available when playing back QuickTime .mov files.

To immediately enter Shuttle Playback Mode from the Main View, press the Control Knob. The cued
file will begin playback at half speed (Fast Forwardx1/2). Shuttle Playback Mode can also be ac­cessed while a file is playing back or when paused by pressing the Control Knob.

When Shuttle Playback Mode is active, the OSD items ABS Time, Timecode, Filename, and
Drive Indicator are displayed in blue. Turn the Control Knob to select playback direction and rate.
The following table defines the playback directions and rates available when turning the Control
Knob in Shuttle Playback Mode.

In Shuttle Playback Mode, the playback direction and rate will be indicated on the LCD if Setup
Menu option [Display - ABS Time] is set to On. The Fast Forward (>>) and Rewind (<<) buttons will
illuminate independently to indicate the playback direction. Press the Control Knob while in Shuttle

Playback

Mode to pause playback. Press the Play () button while in Shuttle Mode to return to Playback
Mode.

Reverse Forward

Cue Marker

During Record, Playback, Pause, or Shuttle mode, press FILES + Fast Forward (>>) to set a
Cue Marker. To delete a Cue Marker, press FILES + Rewind (<<) . A dialog box appears asking
Delete Cue Marker? Cue (number), select OK to delete and Cancel to ignore. Cue Markers added
or deleted during record are applied to all available drives. Cue Markers added or deleted during
playback or shuttle mode are only applied to the current playback drive.

To quickly jump to the next or previous Cue Marker, press Fast Forward (>>) or Rewind (<<) re­spectively. The previous Cue Marker is displayed in the lower left-hand corner of the OSD when
[On-Screen Display - Cue Marker] is On. The OSD field will be displayed in various colors depend­ing on the current transport status: Red = Record, Green = Play, Blue = Rewind/Fast Forward/Shuttle.

Content between consecutive cue markers is referred to as a “segment”. The beginning and end
points of a file are effectively cue markers. A file with a single cue marker will have 2 segments
(From the beginning of the file to Cue 1 and from Cue 1 to the end of the file).

Playback Mode

By default, when a file is selected for playback, the PIX 250i will play the file immedi­ately and stop playback when the end of the file is reached. The Setup Menu options

[System - Playback Start mode] and [System - Playback mode] alter this behavior. When
[System - Playback Start mode] is set to Pause on First Frame, a file will begin playback in a paused

state on the first frame. This is useful for “loading” a clip so that playback can be manually triggered
without any start up delay.

The Setup Menu option [System - Playback mode] affects how playback will continue after the end
of a file is reached (assuming no user transport commands are called):

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.

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

Synchronization & Timecode

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 synchro-
nizes 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 35)

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.

34

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
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.

PIX 250i User Guide

Sync Reference

The following table lists the available sources for sync reference.

Signal Connection OSD

HDMI video HDMI input

SDI video SDI input

Genlock SYNC IN

Internal None

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.

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.

Sync: HDMI

Sync: SDI

Sync: VidRef

Sync: Int

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 play-
back 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 red during playback to indicate that the sync source is not
present.

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 35).

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.

Synchronization & Timecode

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.

35

PIX 250i User Guide

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.

Synchronization & Timecode

Setting the Sync Out

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 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.

It is not possible to pass the Sync Input signal to the Sync Output (this is not a loopthrough).

Timecode Modes

Freerun Timecode 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].

36

Freerun Auto Mute

Functions the same as Freerun mode except timecode signal is muted from the timecode 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 gen­erated. A user-defined value can be jammed into the internal generator from the Setup Menu option
[Timecode/Sync - Set Generator TC].

v. 2.10 Features and specifications are subject to change. Visit www.sounddevices.com for the latest documentation.

PIX 250i User Guide

24 Hour Run Timecode Mode

Generator mode. Timecode runs continuously. When this Time Code Mode is selected or when the
time/date is altered, the timecode 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

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 37). If the external timecode is removed the internal genera-

tor continues to run to preserve continuous timecode.

External Timecode Halt Mode

Reader mode. Identical to normal External Timecode mode, except that when external timecode
is removed (signal is lost), the internal timecode does not continue. When Setup Menu option
[Remote Control - Rec Start/Stop] is set to Timecode, this mode will cause the PIX 250i to stop
recording when timecode signal is disconnected or invalid (In addition to stopping when stationary
timecode is received).

Timecode Frame Rate

When using external timecode and 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 (Sony) 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

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 one of the external
timecode modes 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 sig-

Powering

The PIX 250i features an advanced powering system with PowerSafe technology. By default, the PIX
250i operates from the DC power source. When the DC power source is removed, PowerSafe circuit­ry activates. The PIX 250i displays a warning, stops any active recordings, finishes writing files, and
shuts the PIX 250i down. The PowerSafe Battery powers the PIX 250i during this time. This feature
ensures that files are protected even in the event of unexpected power loss.

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, unless otherwise specified.

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 in 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 + Control Knob.

Requirements and considerations when setting up Network Groups:

• 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-con­guration.

• 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-congure before proceeding with grouped operations. See the
following section for details. (See “Group Auto-Conguration”, page 42)

• Some seings are not linked even when units are in the same group. (See “Grouped Seings”, page

41)

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 (or be pushed when Setup
Menu option [Network - Grouping - Push Settings to Group] is used):

• 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]

• [System - Update Software]

PIX 250i User Guide

Pushing Settings to Group

When a unit is assigned to a group, none of its settings are immediately changed. Subse­quent settings changes to any unit in the group will be applied to all units in the group. To
copy all settings from one unit to the rest of the units in the group, access Setup Menu option
[Network - Grouping - Push settings to group]. This will copy all grouped settings to all other units
in the group.

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 o.

• A unit is connected or disconnected from the LAN.

Network Grouping

• 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 Rewind) 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.

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 le

• 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.

42

To effectively use Cue Markers with grouped units:

1. Playback a le.

2. Find the spot in the le in which a cue marker is to be placed.

3. Pause Playback.

4. Press FILES + Fast Forward to lay a cue marker.

PIX 250i User Guide

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.

Triggering Recording from External Timecode

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:

External Control

1. Set Setup Menu option [Remote Control - Rec Start/Stop] to Timecode.

2. Make sure that the device that is sending timecode is congured to send stationary

timecode while stopped and running timecode while recording. To cause the PIX 250i
to stop recording when linear timecode signal is absent (disconnected), set Setup Menu option
[Timecode/Sync - Timecode Mode] to Ext TC (LTC Halt).

3. Some cameras do not send the correct timecode in the rst few seconds of a recording, or
they send short bursts of timecode causing the PIX 250i to record short unintentional les or

incorrect timecode values. The [Timecode/Sync - Auto Record Hold Off] feature is designed

to eliminate these issues. When a hold o 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 o 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. Setup Menu option [Timecode/Sync - Timecode Mode] must also be set to

Ext TC (SDI,HDMI).

GPIO (General Purpose Input / Output)

GPIO inputs (pins 1, 2, and 3) and GPIO outputs (pins 6, 7, and 8) can be set to “logic high” or “logic
low”. Logic high connections will trigger to the presence of +5V (GPIO input) or output +5V when
the function is active (GPIO output). Logic low connections will trigger when connected to ground
(GPIO input) or become connected to ground when the function is active (GPIO output).

To configure GPIO connections as logic high or logic low, access Setup Menu option
[Remote Control - GPIO Inputs] or [Remote Control - GPIO Outputs].

The GPIO Outputs can be used to drive LEDs with a proper series resistor. Resistor values will vary
from LED to LED, 470 ohms is a good starting point.

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 that are accessed by pulling the LCD Handle forward and tilting the LCD
down.

PIX-CADDY 2

Drives 1 and 2 are PIX-CADDY 2 slots behind the LCD on the Front panel.

The PIX-CADDY 2 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
and FireWire 800 connections are disabled. When the PIX-CADDY 2 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 2 documentation for details on attaching a

2.5” drive to the PIX-CADDY 2.

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 an exFAT filesystem. The exFAT filesystem is readable and writ­able by Mac OS X, Windows 8, Windows 7, and Windows Vista. Files stored in an 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 firmware 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

Storage & File Management

To format a drive:

1. Make sure the drive to be formaed is connected to the recorder and note which drive num-

ber it is.

2. Open Setup Menu option [File Storage - Erase/Re-format].

53

PIX 250i User Guide

3. Choose the Erase/Re-format: Drive Number for the drive to be formaed or
Erase/Re-format: All Drives option.

4. A conrmation 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 aached) to enter a
volume label for the drive, and then use the Control Knob to select OK to initiate the format.
When formaing all drives at once, the volume label is applied to all drives but each drive
will be suxed with a dash 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 two drive slots can be set to Read Only, Record,
Ethernet File Transfer, or Switch to Network upon Full from the Setup Menu option
[File Storage - Drive Record/Network Mode].

Storage & File Management

• Read Only: Drives in this mode 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 in this mode will be written to for recording. This is the default mode.

• Ethernet File Transfer: Drives in this mode will be shared to the network as a standard Samba

share (see Ethernet File Transfer) and cannot be recorded to, formatted, or accessed for playback
from the unit.

• Switch to Network upon Full: Drives in this mode will be in Record mode until they are filled.

Once filled, they will be put into Ethernet File Transfer mode.

When [File Storage - Video 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 - Video 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 Record will be written to at the same time.

When set to Sequential (available in Video Mode only), the lowest numbered drive that is online
and set to Record mode will be written to. When that drive is full the recording will continue on the
next available drive that is online and set to Record mode. If no drive is available, recording will
stop. The order of drives when recording sequentially is from lowest (Drive 1) to highest (Drive 4).

54

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. (See “Take

Details Screen”, page 10)

PIX recorders support SMPTE-315M camera positioning metadata for ProRes recordings, but DNxHD
files generated by the recorders will not contain SMPTE-315M metadata.

v. 2.10 Features and specifications are subject to change. Visit www.sounddevices.com for the latest documentation.

PIX 250i User Guide

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. This value is
alpha-numeric.

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 an 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: (Default) 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 an 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 an alpha character precedes it - that character 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 no 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 Take Details for navigation and basic overview.

Storage & File Management

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

55

PIX 250i User Guide

this new file will be seamless to the ending of the previous file. The Setup Menu option
[File Storage - QuickTime File Split every] adjusts the amount of time before a file split occurs.

File Naming

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
Drive Name, 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 les that follow the same naming convention used by RED cameras.

• Extract the CamID, Reel number, Clip number, and date from the SDI input signal from a RED

Folder Structure

All files generated by the PIX 250i are placed into a Reel folder. The Reel Folder name is defined by a
setting in [File Storage - Reel Format], and the number is defined by the Reel metadata, which is set
in [File Storage - Reel].

56

For the folder name, the default is Custom, which lets you set your own alphanumeric value for Reel
folder names. The alternative option is Daily, which if chosen, automatically generates folder names
based on the system’s date in the YYMMDD format, where Y is a two-digit numerical value for year,
M for month, and D for the day.

When using the RED or Arri File Formats, the PIX 250i will generate a Reel folder based on the cam­era’s reel metadata.

Files on PIX 250i formatted storage volumes 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. Aach 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/Net-

work mode menu for all drives.

Storage & File Management

3. Select the drive to be mounted and set its mode to Ethernet File Transfer. This drive is now
aached to the Network and unavailable to the PIX 250i for read or write actions. The Drive
Status eld on the OSD will read “Network” in this mode.

4. Now the drive is ready to be accessed via the network. The IP address to use
for network access to the PIX 250i is shown on the OSD and in Setup Menu
[Network - IP Address]. The user name and password are congured from Setup Menu op-

tion [Network - Authentication].

PIX 250i User Guide

Storage & File Management

• Mac OSX: From the Finder, select Go > Connect to Server. Enter the PIX 250i address as

“smb://[IP Address]” then click Connect. Enter the user name and password.

• Windows: Click the Start buon (or press the Windows key on the keyboard). In the

search box, enter the PIX 250i address as “\\[IP Address]”. Enter the user name and pass-

word.

5. Drives that are in Ethernet File Transfer mode will appear as folders in the mounted volume
on the computer. When no drives are set to Ethernet File Transfer mode, a folder titled “No_
Drives_Aached” will appear instead.

6. Set the drive’s mode to Record to remove it from the network and make it available for
recording and playback on the PIX 250i. Allow time for the drives to remount before Record­ing or Playing back les. The Drive Status OSD eld will return to white when the drives are

ready.

FileSafe Utility and the Sound Devices File Format

During recording, PIX recorders store data in a temporary file format with the extension .sdv. When
the recording is completed, the file is converted to its standard .mov format. In the event of unin­tended drive removal or power loss during recording, these files can be recovered by the PIX re­corder itself or with the FileSafe software utility. Upon powering up, the PIX recorder will search all
connected drives for .sdv files and convert them to .mov format.

The FileSafe utility (currently available for Windows OS) can be used to recover .sdv files in the ab­sence of a PIX recorder. Download the FileSafe utility from the Sound Devices website:

http://www.sounddevices.com/products/filesafe/downloads/

Setup Management and Firmware Upgrades

Saving and Loading Setup Files

To save all of the current settings to a setup file, select the Setup Menu option
[Quick Setup - Save Settings to Drive 1]. Use the on-screen keyboard (or attached USB key­board) to enter a name for the setup file. This will save all of the current settings to an XML
file at root of Drive 1. To load a previously saved setup file, select the Setup Menu option
[Quick Setup - Load Settings from Drive 1]. The setup XML file will have to be copied to the root of
Drive 1 prior to attempting to load it.

For a complete list of available Setup Menu options, see Setup Menu Options.

Formatting a storage device will also remove any setup files that are on the drive. Setup files can be stored
on a computer and copied back to the root of a PIX 250i drive to be loaded on the PIX 250i.

Custom Default Settings and Setup Menu Option Visibility

The Setup Menu option [Quick Setup - Load Factory Settings] loads a setup that is saved internally
to the PIX when it leaves the factory. It is possible to alter this “factory” setup, so that the Setup
Menu option [Quick Setup - Load Factory Settings] will load a custom default.

It is also possible to hide specific Setup Menu parameters and options. This is useful for Setup Menu
options that are not commonly used in a particular workflow, or to simplify use when lending the
unit to another user.

To customize defaults and Setup Menu option visibility:

1. Aach a USB keyboard to the PIX 250i’s USB keyboard port.

2. Press MENU to enter the Setup Menu.

3. Press Ctrl + Alt + F10 on the keyboard. If this is the rst time this action has been performed
since powering the PIX 250i up, a password dialog will appear. Enter the password (the de­fault password is “default”).

4. After the correct password has been entered, the Seings Customization Menu will appear.
Select Edit Menu & Default Values.

PIX 250i User Guide

The Settings Customization Menu option Reset to Factory Settings will make all Setup Menu items
visible and revert default settings to factory defaults.

Factory Restore

To fully restore the unit to its factory firmware state, hold Fast Forward and Stop while booting the
PIX 250i up, until the Main View appears. This will load factory default settings and restore some
settings that are normally not affected by performing [Quick Setup - Load Factory Settings], such as
restoring the network user name and password to “guest”.

Firmware Upgrades

At times, Sound Devices makes firmware updates available for PIX 250i. These updates are easy to
apply:

1. Download the new .prg le from the Sound Devices website.

2. Copy this le to an approved drive, and connect to the PIX 250i.

3. Ensure that the power source for the PIX 250i is reliable. Power loss during a rmware up-

grade process can produce unexpected results.

4. From the System menu in the Setup Menu, select Firmware Update. The PIX 250i will search
for the .prg le and give the option to install the rst le that it nds (cancelling this dialog
will cause the PIX to search for another .prg on any aached storage devices). When the cor­rect .prg le has been located, highlight the OK buon and press the Control Knob to begin
the rmware update.

5. The PIX will verify that the le is not corrupted, then it will update the rmware. When done

the unit will need to be powered down and then back up.

Firmware updates can take several minutes to complete. Never pull power during a firmware update.

Various functions and ports may become inactive while firmware is updating.
