xAI: Grok Imagine Video Edits API

Grok-Imagine-Video/Edits is the video-to-video semantic editing endpoint. Unlike generative models that rebuild the scene from scratch, it modifies specific elements of the footage from a natural-language prompt while preserving the original motion and lighting — swapping clothing, replacing objects, or shifting mood and color grade in a single instruction. Duration, aspect ratio and resolution are all inherited from the source video and cannot be set independently; output resolution is capped at 720p. Well suited to instant VFX, meme production and fast color work.
