Apple DVD Studio Pro 4 - Manual (Page 391)

To help guide you when trimming your clip, drag the playhead to the point you want to
edit to. A vertical line appears across all streams, which you can use as a guide to trim an
edge to. Be sure to use the timeline zoom feature to provide a close-up view of the area
you’re editing.
Use care not to lose your video and audio synchronization when trimming. Instead of
dragging, you can enter values in the Start and End boxes at the top of the Track Editor
and the Duration and Clip Start Offset entries in the Clip Inspector to trim a clip more
precisely so that you can repeat exactly the trim on other clips.
To use the start and end values to position and trim a clip
1 Select the clip you want to trim. Its start and end values appear in the Track Editor’s Start
and End boxes.
2 Enter a new Start time. The beginning of the clip moves to that time.
This moves the entire clip, but does not actually trim it.
3 Enter a new End time. The end of the clip is trimmed to that time.
To use the Clip Inspector to trim a clip
1 Select the clip you want to trim.
The clip appears in the Clip Inspector.
2 Enter a new Clip Start Offset to trim the clip’s start.
The clip’s start position on the timeline is not changed—only its end position is moved
to match its new duration.
3 Enter a new Duration value to trim the clip’s end.
Clip Conflicts
There are a number of rules to keep in mind when you trim and position a clip.
Video Clips
Dragging clips to the V1 stream is different from dragging audio clips. In part this is due
to the requirement that there can be no gaps in the V1 stream, and there must be a clip
at its beginning.
The following situations cause video clips already in the V1 stream to move. This can
cause problems if the video clips have associated audio or markers because they do not
move with the video.
• If you drag a video clip to the start of a V1 stream that already has a clip assigned: The
new clip becomes the first clip and the original one (and any that follow it) shuffle
down the timeline.
• If you drag a video clip to the point where two existing video clips meet in a V1 stream: The
new clip is inserted between them.
