Grok Video Extension | Video to Video Continuation
Use Grok Imagine Video Extension in video-to-video mode to continue a short MP4 clip from its last frame using a text instruction.
About this model
xAI video-to-video model for extending a short clip from its final frame with a text instruction.
Best fit tasks
- Continuing a short product, social, teaser, or storyboard clip without restarting the scene from scratch.
- Adding a next beat to footage when the first clip already has the right subject, camera angle, and mood.
- Testing alternate endings or follow-up actions from the same source video.
Main advantages
- The uploaded video controls the starting point because the extension begins from the last frame.
- Pricing is predictable at 5 credits per second of generated extension.
- The dedicated extension workflow keeps this route separate from broad video remixing.
Limitations to know
- The source video must be short: Replicate describes the accepted range as 2-15 seconds.
- The model extends what already exists, so source quality, framing, and the last frame strongly affect the result.
- It is not meant for long-form editing or frame-perfect continuity.
Simple workflow
- Upload a short MP4 source video with a clear final frame.
- Describe only what should happen next: action, camera behavior, mood, and any important sound or atmosphere.
- Choose the extension length from 2 to 10 seconds.
- Start with 4-6 seconds for testing, then increase duration only when the continuation is stable.
Input formats
- MP4 source video; Replicate notes H.264, H.265, or AV1 codec support.
Output
- Generated video extension returned as a video URL.
