Key features

Grok Imagine Extend turns a video you already have into video inside Enhance AI. It produces clips from 5 to 10 seconds at 1080p. Grok Imagine Extend is built by xAI. On Enhance AI it runs on the same account as every other model, with no separate subscription.

Clip length

Grok Imagine Extend renders clips from 5 to 10 seconds, and you pick the length before you render. Longer clips cost more because video is billed by length, so rough out an idea short and only render the full length once the shot works.

Resolution

Grok Imagine Extend renders at 1080p. There is no resolution picker for this model, so every render comes back at the same size. For a bigger frame, run the finished clip through a video upscaler on the same account.

Input modes

Upload a video you already have and Grok Imagine Extend continues it from the last frame, so the new segment matches the light, the framing and the motion of the original. Describe what should happen next and the model carries the shot forward without a visible join.
