Offsetting audio and subtitle tracks
87
Offsets and trimming behavior
You can apply offsets before or after trimming a movie. The illustration below shows the
effects of trimming a movie and offsetting its audio track; the same principle applies to
subtitle tracks. The starting point of the movie is shown here as a vertical line. The Timeline
window does not display the portion of each track that is to the left of the start point.
1.
No trim. No offset:
The video and audio tracks start together and, in this example, they
finish together.
2.
Trimmed. No offset:
The second set of bars shows the movie after the start has been
trimmed. The lighter area to the left of the start point represents the trimmed audio and
video.
3.
Trimmed. Audio offset earlier:
The audio track is given a negative offset. Even more
of the audio is trimmed, and the audio ends before the video.
4.
Trimmed. Audio offset later:
The audio track is given a positive offset. A portion of
the audio that had been trimmed is restored, and the audio track now appears to be
longer than the video track, when viewed in the Timeline window. However, playback
on the finished disc stops when the video ends, so the end of the audio is effectively
trimmed from the movie.
