Chapter 4: Pro Tools Video Track 25
Avid Multi-Cam Resolution Files
(Windows XP Only)
Pro Tools with AVoption|V10 supports all stan-
dard-definition Avid Multi-Cam Resolution files
for import and playback. Pro Tools will play the
clip of an Avid Multi-Cam Resolution file that
was being used as the active camera angle when
the file was exported to AAF or OMF.
Digitizing Video to the
Pro Tools Timeline
Pro Tools with an Avid DNA video peripheral
lets you digitize video directly to the Video track
for use in the Pro Tools editing environment.
Video is digitized in the Avid DV25 file format,
and may be used in the Video track along with
OMF and MXF video clips of other resolutions
that are from other sources. Though the video
files which are captured in Pro Tools are techni-
cally MXF files, they are intended only for use in
Pro Tools. They have not been tested for import
into other applications, and may not be of stan-
dard broadcast quality.
Hardware Requirements and
Options
SYNC I/O Requirement
For digitizing video, Pro Tools requires a SYNC
I/O locked to video reference.
For information about setting up SYNC I/O
hardware and locking the SYNC I/O to video ref-
erence, see the SYNC I/O User’s Guide.
To configure SYNC I/O for digitizing video in
Pro Tools:
1 Ensure that the SYNC I/O is locked to the ap-
propriate video reference for your system setup.
For more information, see the SYNC I/O Guide or
the MachineControl Guide.
2 In the Session Setup window (Setup > Session),
select SYNC I/O from the Clock Source pop-up
menu.
3 Choose a Time Code Rate for the type of video
you want to record.
QuickTime video clips cannot be mixed
with OMF or MXF video clips in the Video
track.
Up to six hours of video can be digitized in
a single record pass.
Each record pass can only record to a single
volume (or a set of striped drives). One video
file cannot be recorded across multiple vol-
umes.
Session Setup window Clock Source selection
Ensure that the Time Code Rate is compat-
ible with the type of video format you plan
to use. For example, NTSC is not compati-
ble with a Time Code Rate of 25 frames per
second.
