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.

Sequence Render Image

Render the an image at the current frame.

Sequence Render Animation

Render timeline from Preview Start to Preview End Frame to a Video file or series of images.

Export Subtitles: Exports Text strips, which can act as subtitles, to a SubRip file (.srt). The exported file contains all Text strips in the video sequence.
Toggle Sequencer/Preview Ctrl-Tab: Switch the editor display type between Sequencer and Preview.
