About the Marker Types

There are four types of markers you can have in the track. One marker can be one or more of these types. The color of a marker in the Track Editor indicates its type—if you configure a marker to be more than one type, the marker symbol splits to display the relevant colors.

The types of markers and their colors are:

You define the type of marker in the Marker Inspector. Additionally, you can set a marker to be a button highlight type by Control-clicking it and choosing Button Highlight Marker from the shortcut menu.

Note: Only chapter markers can be connected to from menu buttons and scripts.

Each marker has a duration that is determined by the distance between it and the next marker. This duration is especially important when using button highlight markers, because it determines how long the highlights display over the video, and when creating stories, because it determines the length of each story’s segment. See Creating Buttons over Video and Introduction to Stories for more information.

Chapter Markers

By default, all markers you create start out as chapter markers. Viewers can jump to these markers by pressing the Previous and Next buttons on their DVD player’s remote control. Because of this, even simple projects without a chapter index menu can benefit by having chapter markers added to the track because they provide a viewer with the ability to quickly skip through sections of a track.

Only chapter markers can be connected to from other project elements such as menu buttons and scripts, and a track’s story can only use track sections defined by chapter markers. While a track can have up to 255 markers, it is limited to a maximum of 99 chapter markers.

Note: The Previous and Next buttons can act differently on different DVD players. See Getting Consistent Previous and Next Button Behavior for more information.

Chapter markers have an end jump setting. By default, this is set to Not Set, which actually means that playback will automatically jump to the next video frame. In almost all cases you will leave the End Jump set to Not Set; however, you may have non-standard situations where you need to set the End Jump to a specific element. In these cases, you are limited to a maximum of 106 chapter markers and individual end jump chapter settings. See Setting Chapter Marker End Jumps for more information.

Note: The DVD specification does not allow subtitles to extend across chapter markers. For that reason, subtitles that cross chapter markers are automatically split into multiple subtitle clips at each marker when you build your project.

Button Highlight Markers

You use button highlight markers when you want to have buttons display over the video on the track. These buttons are actually configured as part of a subtitle clip. The buttons appear once you reach the marker and disappear when you reach the next marker (unless it has also been configured as a button highlight marker). Often referred to as “buttons over video,” this feature allows you to provide choices to viewers while they watch the track part of the title. See Creating Buttons over Video for more information on using buttons over video.

Important: There must be at least 1.5 seconds between a button highlight marker and the next marker.

Dual-Layer Break Markers

When you create a dual-layer title, you can set a marker to be used as the dual-layer break point, the point where the title splits between the first and second layer. Because the break point is often noticeable when playing the disc on a DVD player (the video temporarily freezes), you want to try to choose a place in the track where the freezing is not as noticeable. See About Choosing a Dual-Layer Break Point for details on choosing a dual-layer break point.

Cell Markers

All markers define a cell in the track. A cell marker is a marker that has no specific assignment. They are often added to a track to start a DVD@CCESS action or to provide a break point for a button highlight marker.
