Apple Soundtrack Pro 3 - Manual (Page 118)

When you import a video file into a Soundtrack Pro project, the Time display and Time
ruler adjust to show the timecode format of the video. The Time display and Time ruler
can display time in seconds, frames, drop frames, or non-drop frames. You can choose
the format for timecode display, and you can set the video frame rate for projects not
containing a video file. You can also set the default frame rate for new projects in the
Project Preferences pane.
To specify the details of the units shown in the Time display and Time ruler
1 Choose View > Time Ruler Units, then choose one of the following time formats from the
submenu:
• HH:MM:SS
• Seconds
• Samples (Audio file projects only)
• Frames
• Drop frame (timecode)
• Non-drop frame (timecode)
2 If your project does not contain video, you can also specify the following settings:
• Set Video Frame Rate: Choose from the following: 23.98, 24, 25, 29.97, 30, 59.94, 60.
• Set Starting Timecode: Enter the timecode for the first frame of your project.
Time Ruler Units and Gridlines
The number of gridlines drawn will depend on the dominant ruler type and zoom level.
For example, when the dominant ruler is Seconds and the Timeline is zoomed out, gridlines
appear only on the hour marks. As you zoom in, gridlines are drawn on the minute mark.
Zoom in more, and gridlines are drawn on the second marks, and so on.
Setting the Project Length
By default, the length of a project depends on the media in the project. The project length
is set to the end of the last clip in the project. If the project uses a time-based effect, and
the effect extends past the end of the last clip, the project length extends to include the
effect’s “tail.” Adding a clip to the end of the project, or adding an effect that produces
a “tail,” extends the project length to include the new clip or the effect’s tail. You can
optionally set the project to a definite length.
