ENCORE CS3 116 User Guide Timeline Viewer overview A Timeline Viewer displays all of the components of a timeline, including its time ruler, a video track, and optional tracks for audio and subtitles. The time scale used in the ruler depends on the editing timebase of the project: for example, 29.97 fps for NTSC media and 25 fps for PAL media. You place the assets and subtitles on the tracks below the ruler. Depending on how the User Interface preferences are set, timelines can be displayed in separate viewers (click on their tabs to select them) and they can be grouped together in a single viewer and you select them from the tab's popup menu. Note: All timelines in a project are written to disc, even if they aren't linked to anything. Make sure to delete any orphaned (unlinked) timelines you do not want to use.

Zoom slider A Timeline Viewer includes the following elements: Add Chapter button Adds a chapter point at the current-time indicator. Current-time indicator Indicates the current edit point in the timeline. This location is reflected by the frame displayed in the Monitor panel. Similar to a cursor in text or the playback head on a video player, the current-time indicator points to the current location in the clip and determines the timecode display. Chapter point Marks a chapter point within the video. Chapter points are useful for jumping to scenes in the content and can be linked from menus, buttons, and other timelines. (See "Add chapter points" on page 132.) GOP header Indicates the location of a GOP (Group of Pictures) header in an MPEG-2 video. GOP headers are displayed as gray vertical lines along the bottom edge of the ruler. They are visible only if you've zoomed in sufficiently. If you've added an AVI or MOV file, you will not see GOP headers until the timeline is transcoded. (See "About chapter points" on page 132.) Poster frame Marks the frame to display in a video thumbnail button. (See "Create video thumbnail buttons" on page 87.) Timeline tab Lets you determine which timeline to display in the viewer by either clicking individual tabs or by selecting a timeline name from a tab menu (depending on your User Interface preferences for the Timeline Viewer). See "Set preferences for your workspace" on page 23.
