About the V1 Stream
The first video stream, V1, has requirements different from the other streams.
DVD Studio Pro automatically ensures these conditions are met.
• The first clip must be at the beginning of the timeline. There cannot be a gap between
the timeline’s first frame and the first frame of the V1 clip. All other streams, including
the other video streams, can have their first clip start anywhere in the timeline.
• You cannot have gaps between clips in the V1 stream. All other streams can have gaps
between their clips.
• When building the project, the track ends at the last frame of video in the V1 stream.
Any streams that have clips extending beyond the V1 clips are automatically truncated
by the build process.
