 Edit: Only available when the playhead is positioned on a marker. Choosing Edit
opens a dialog for naming the marker. Naming a marker makes it a chapter marker
that can be used in DVD Studio Pro.

names) are shown in the timeline. A checkmark indicates they are shown.
 Show edit/cut markers: Controls whether markers automatically placed at each edit

Previewing a Clip
You can preview either a source media file clip or a clip with a setting assigned to it.
Source media files have no settings assigned to them; in the Batch Item pop-up menu,
they appear with a format icon—such as QuickTime—next to their names. (Clips with
settings don’t have any format icons next to their names, just the setting name.) The
kind of clip you choose determines which options you see in the Preview window.
To preview a source media file:
1 Open the Preview window.
Note: You can open your file into the Preview window in one step, by double-clicking
the source media file in the Batch table of the Batch window.
2 Do one of the following:
 Choose a source media file from the Batch Item pop-up menu (identified by its
format icon).
 Click the Batch Item selection buttons until the source media file appears in the
pop-up menu
 Select the source media file in the Batch table of the Batch window.
Only the Source View button is active (and the Output View button is dimmed). This is
because you selected a regular source media file with no setting assigned, so you can
only see the unadulterated clip—without the split screen divider or cropping bars.
