Apple DVD Studio Pro 4 - Manual (Page 381)

If you choose the asset-based timecode source, you can also choose whether to use the
clip’s timecode or a value you enter.
To configure the asset-based timecode source
1 Choose Asset-Based Timecode as the timecode source for the Track Editor’s timeline.
2 Click the Other tab in the Track Inspector. If the Inspector is not showing the track
properties, select the track’s name in the Outline tab, its tile in the Graphical tab, or click
an empty area in any of the Track Editor streams.
3 Do one of the following:
• To use the timecode from the first clip in the V1 stream: Click the Reset button. This sets
the Track Offset value to 00:00:00:00, which forces the timeline to use the clip’s timecode.
• To set the timecode to start at a specific value: Enter a new timecode value in the Track
Offset field. The timeline’s first frame is set to this number.
Being able to force the timeline’s timecode to start at a specific value can be useful
whenever you are importing a marker list or subtitle file that is based on timecode different
from the zero-based or asset-based values.
Note: For NTSC projects, the type of timecode in the first asset—drop frame or non-drop
frame—determines the type of timecode for the timeline.
