Grok Imagine Video — AI video generator

xAI's video model, at 480p or 720p in six or ten seconds.

Grok Imagine Video is xAI's text-to-video model. It offers a wider set of aspect ratios than the Kling family — seven shapes rather than three, including 4:3, 3:2 and their portrait inversions — which matters when the clip has to sit in a layout that is not 16:9 or a phone screen.

Six and ten second durations give a little more room than Kling's five, and output runs to 720p. It suits social and web use where the delivery resolution is modest anyway and the framing is unusual.
