Extend Video
More seconds from the shot you already have. Continue a clip past its last frame. Describe where the scene goes and the new seconds pick up the same look, motion, and sound.
Breme extends a video by continuing it from the source clip with Grok Extend. It adds 2 to 10 seconds guided by a prompt, keeps the original aspect ratio, and generates synced audio for the new footage.
