Playhead

The playhead displays the current time in the sequence and is one of the main controls for timeline interactions.

During playback it will move across the timeline at the specified playrate and can be stopped in place by pausing.

You can drag the playhead to change the current time in the sequence, and preview changes in the viewport.

This is commonly referred to as "scrubbing".

You can fast forward the playhead to other areas of the timeline by holding Shift and double-clicking a region of the timebar.

Marks can also function as Determinism Fences. Determinism Fences force the engine to evaluate on the same frame as the mark, even if normal engine ticking would have skipped over it during playback. They are useful for resolving issues related to events or keyframes being skipped when a sequence or sub sequence is being played.

Playback Controls

The playback controls can be found in the bottom-left corner of Sequencer and function similarly to standard media playback applications.

Buttons for toggling playing, pausing, and other playback-related functions are found here.
