About Marker Placement

Markers can only be placed on Group of Pictures (GOP) boundaries. Because of this
restriction, you cannot precisely position a marker on the exact frame you want to—you
often need to set the marker either a little early or a little late. The length of the GOP
depends on the MPEG encoder’s settings (NTSC systems commonly use a GOP size of
15 frames and PAL systems commonly use a GOP size of 12 frames). This means that,
unless you embed markers with a video editor, you may need to set a marker as much
as 6 or 7 frames from where you’d like.

If you import markers from a timecode list, the markers are moved to a GOP boundary
when they are imported. The Track pane in DVD Studio Pro Preferences lets you choose
how the markers are placed. See

Track Preferences

for more information.

If you import a video asset edited with a version of Final Cut Pro or Final Cut Express that
supports chapter markers, the integrated MPEG encoder automatically adds GOP
boundaries at the marker frames, so the markers end up positioned exactly where

Creating and Editing Tracks

If you convert a slideshow to a track, each still clip has a marker placed at its beginning.
The markers are named the same as the still asset used for its clip. These markers retain
any pause and DVD@CCESS settings that may have been set in the Slideshow editor. If
any slides use transitions, the transitions appear as a shaded area in the timeline with a
cell marker at their beginning.

Transition indicator

You can configure the transition by selecting the clip and making changes in the Clip
Inspector’s Transition tab. If a still with a transition also has a pause, the marker for the
next clip is placed at the beginning of the transition instead of at the next clip’s start. See
