- Refresh All
To force Blender to re-read in files, and to force a re-render of the 3D Viewport, click the Refresh Sequencer button. Blender will update and synchronize all cached images and compute the current frame.
Certain operations, like moving an object in the 3D Viewport, may not force the Sequencer to call for a refresh of the rendered image (since the movement may not affect the rendered image). If an image or video, used as a strip, is changed by some application outside of Blender, Blender has no real way of being notified from your operating system.
- Sync Visible Range
Synchronize the visible range with other time based editors.

Markers are used to denote frames with key points or significant events within an animation. Like with most animation editors, markers are shown at the bottom of the editor.
For descriptions of the different marker tools see Editing Markers.
Adjusting the View
Use these shortcuts to adjust the sequence area of the editor:
Vertical Scroll: use Shift-Wheel, or drag on the left scrollbar.
Horizontal Scroll: use Ctrl-Wheel, or drag on the lower scrollbar.
Scale View: Ctrl-MMB and drag up/down (vertical scale) or left/right (horizontal scale).
Scale View Vertically: drag on the circles on the vertical scrollbar.
Scale View Horizontally: drag on the circles on the horizontal scrollbar.
The Playhead is the blue vertical line with the current frame number at the top. It can be set or moved to a new position by pressing or holding LMB in scrubbing area at the top of the timeline. You can move the Playhead in increments by pressing Left or Right, or by using Alt-Wheel. You can also jump to the beginning or end frame by pressing Shift-Left or Shift-Right. As you do, the image for that frame is displayed in the Preview region.
When you drag the frame indicator with Shift-RMB directly on a sequence strip, this will show the strip solo, (temporarily disregarding effects and other strips, showing only this strip’s output) and the strip will be highlighted.
When holding Ctrl while dragging it will snap to the start and endpoints of strips.
Real-time preview is possible on reasonable computers
when viewing an image sequence or movie (
Scene strips can use viewport previews or proxies for real-time playback,
otherwise displaying rendered frame is supported, but typically too slow for real-time playback.
Every other synced editor can be used for scrubbing e.g. the Timeline.
