Chapter 4: Avid Unity ISIS Workflows for Pro Tools 71
In order to export frame accurate audio regions,
Pro Tools splits the audio media on frame
boundaries and fills any gaps with silence. The
following illustration shows the resulting audio
regions that are exported to the Avid applica-
tion.
To cut down on the number of sample accurate
edit files, the Pro Tools editor can perform a
Bounce to disk for each track (or a bus-record to
an audio track) rather than exporting tracks that
contain all of the audio edits.
Synchronizing Audio with an
Avid Sequence
Once you have imported an audio file or se-
quence from Pro Tools into a bin in the Avid ap-
plication, you can synchronize it with video.
This is especially useful for verifying sync with
the original video sequence, then laying audio
and video back to tape or creating a digital
movie with your final mix.
To synchronize an edited audio file or sequence
with the original video sequence:
1 Ensure that the audio exported from Pro Tools
is now residing in a bin within your current
project.
2 Drag the original sequence to the Record
Monitor to see all elements in the Timeline.
The original sequence displays in the Timeline.
3 Drag the imported audio clip or sequence
from the bin to the Source Monitor. New Source
Track buttons for the source appear to the left of
the Track buttons for the Timeline.
