Timeline Navigation

Panning and zooming are used to navigate within the timeline.


You can pan your view vertically by dragging the right-side scrollbar up and down.

sequencer timeline pan

You can also pan and zoom horizontally using the Range Slider at the bottom of the timeline.

Dragging the middle area of the slider pans, while dragging the left/right margins will zoom your view.

sequencer timeline pan

The Range Slider is enabled by default and can be disabled from the View Options dropdown in the Sequencer toolbar.

Holding RMB and dragging along the timeline enables panning horizontally and vertically.

Scrolling will pan the timeline up and down, while holding Shift and scrolling will pan the timeline left and right.

You can zoom in the timeline by holding CTRL and scrolling.

sequencer timeline zoom

By holding ALT + Shift and click-drag RMB left and right you can free-form zoom.

sequencer timeline zoom

By holding CTRL and dragging along the time bar to the right, you can define a zoom region. Holding CTRL and dragging the time bar to the left resets the zoom back to full.

sequencer timeline zoom

The zoom pivot is relative to the playhead by default and can be changed by locating the Zoom Position preference in the Editor Preferences and Project Settings.

If your zoom and timeline framing have overextended, you can reset your zoom and timeline framing by pressing the Home key, which also resets the bounds of the range slider.

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.

sequencer playhead

You can LMB drag the playhead to change the current time in the sequence, and preview changes in the viewport. This is commonly referred to as "scrubbing".

sequencer scrubbing

MMB dragging causes the playhead to change to the selected position without causing the sequence to evaluate. This technique is used to change time, without changing property values and can be used to create same-value keyframes quickly. When manipulating the playhead in this way, it will change its color to yellow, to indicate the sequence is not evaluating.

sequencer middle mouse scrubbing

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

sequencer fast forward

The current time of the playhead is displayed and can be manipulated from the sequence outliner. You can press CTRL + T to focus selection to this field and type in a new time value.

sequencer current time

You can also right-click the playhead or anywhere on the time bar to reveal additional options.

Set Start Time

Changes the start time of the sequence to the current position of your cursor. If using the hotkey it will set to the playhead instead.

Set Selection Start

Sets the start point of a custom timeline selection range to your cursor.

Selection Ranges

Selection ranges are custom regions you can define in a sequence to assist with timeline selection and playback.

To create a selection range, right- click a point in the timeline bar and set a Start and End Selection Range.

The selection range handles can be adjusted similarly to the start and end times of the sequence.

Selection ranges can also be used to select keyframes and sections within them by clicking the Actions toolbar button and selecting Select Keys in Selection Range or Select Sections in Selection Range.

Custom Marks

Custom marks are points you can add to call attention to areas or provide annotation for your sequence.

sequencer mark

To create a mark, right-click a point in the timeline bar and select Add Mark.

To edit a mark, right-click it to view its details. Here you can customize its properties such as Label, Color and Frame Number.

sequencer edit mark

Marks within Subscenes, Shots, or Template Sequences can be viewed from the parent sequence if you enable Show Marked Frames Globally from the View Options menu.

show marked frames globally

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.
