Manually Adding and Removing Markers
The Preview window includes comprehensive marker support, including the ability to
manage markers already added to the source media file, manually add or remove markers,
and import chapter marker lists. When you add a marker to a clip, it appears as a chapter
marker by default. You can then change the marker to a compression or podcast marker
if you wish (see
