Grok Imagine Video Extension: AI Video Continuation

Seedance 2.5 IS HERE · Nano Banana 2 & GPT Image 2.5 UNLIMITED UNTIL September 30Upgrade

Overview

Grok Imagine Video Extension takes a short clip you already have and continues it from the final frame, generating new footage based on a text description of what comes next. If you filmed a scene that ended too soon, or need to show what happens after the last shot without re-shooting, this model handles it in one step on Picasso IA. You write a prompt describing the next action, camera movement, or mood change you want, and the model produces a natural continuation that visually matches your original clip. It is built for video editors, content creators, and social media producers who need to extend footage without returning to set.

How It Works

Upload your source video as an MP4 file (H.264, H.265, or AV1 codec), between 2 and 15 seconds long
Write a prompt describing what should happen next: the action, movement, mood, or visual change you want to see
Choose the duration for the extension, up to 6 seconds (6 seconds is the default)
The model reads the final frame of your clip and uses it as the visual anchor for the generated continuation
Download the extended video and combine it with your original footage in any editing software

Frequently Asked Questions

Do I need programming skills or technical knowledge to use this? No, just open Grok Imagine Video Extension on Picasso IA, adjust the settings you want, and hit generate.

Is it free to try? You can run the model directly on Picasso IA without installing anything. Check the credits section for details on current generation limits.

How long does it take to get results? Most extensions up to 6 seconds are ready within a minute or two. Processing time may vary depending on server load at the time you run it.

What video formats are supported for upload? The model accepts MP4 files encoded with H.264, H.265, or AV1 codecs. Your source clip must be between 2 and 15 seconds long to work correctly.

Can I customize the output quality or style? You control the style through your text prompt and can adjust the extension length. Describing the lighting, camera angle, or subject movement in detail gives you more precise results.

What happens if I'm not happy with the result? Run the model again with a revised prompt. Changing specific details like the direction of movement, the speed, or the scene description usually produces a noticeably different output.

Where can I use the outputs? The videos are yours to download and use in social content, short films, ads, or any personal or commercial project. No watermarks are added to the output.
