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 op-
tion [File Storage - Video Record Mode]). Each drive can be configured independent-
ly to be available for recording, available for playback (read-only), shared on the net-
work 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 simul-
taneously (
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 com-
mand 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.
The Setup Menu is not accessible during recording and playback. The File List is not accessible dur-
ing 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
