Grok Imagine Video Extend
Generated on PixelDojo with Grok Imagine Video Extend. Produced by PixelDojo's generation pipeline.
Grok Imagine Video Extend costs 1.5 credits for every second of the finished clip, your source plus the new footage, rounded up to a whole second. Give it any MP4 from 2 to 15 seconds and a prompt for what happens next, and it adds 2 to 10 seconds after the last frame. It works on footage from anywhere, not just Pixel Dojo generations, and it runs in Canvas and over the API.
How it works
1.5 credits per second of the finished clip
The price covers the whole output: your source seconds plus the extension, rounded up to a whole second. We measure the source for you before the job starts.
It continues a clip
Send an existing MP4, 2 to 15 seconds long, plus a prompt describing what happens after the last frame. The new footage picks up where yours ends.
It keeps your clip's look
No resolution or aspect ratio to set. The extension matches the source clip.
Built into Canvas
Extend a clip you generated earlier in a Canvas session in place, with one typed prompt.
Why Choose Pixel Dojo for Grok Imagine Video Extend
Professional-quality results with cutting-edge AI technology
One simple formula
1.5 credits per second of the finished clip. No resolution tiers.
Works on footage from anywhere
Any standard MP4 or MOV between 2 and 15 seconds, made on Pixel Dojo or anywhere else.
Trim first, extend tighter
Because the source counts, trim to the part you need before you extend.
How It Works
Three steps:
Point it at an existing MP4
video_url points to an MP4 or MOV, 2 to 15 seconds long. We read its length for you.
Describe what happens after the last frame
The prompt is written as a continuation instruction, for example camera pans across the city at night, not a full scene description.
Set extension_duration
2 to 10 seconds, 6 by default.

Common Questions
Everything you need to know about Grok Imagine Video Extend
What does Grok Imagine Video Extend cost?
1.5 credits per second of the finished clip, the source plus the new footage, rounded up to a whole second. Adding the default 6 seconds to a 5 second clip is 16.5 credits.
How long can the extension be?
2 to 10 seconds per request, on a source clip of 2 to 15 seconds. To go longer, run it again on the extended file. For films up to 3 minutes, Film Studio plans and cuts the whole thing for you.
How is this different from Grok R2V?
Grok R2V makes a new clip from 1 to 7 reference images and a prompt, at 2 credits per second. Video Extend continues a clip you already have.
Can I automate it?
Yes. Every model is in one REST API at /api/v1/models/{apiId}/run, and the Pixel Dojo MCP server at pixeldojo.ai/mcp puts it inside Claude, ChatGPT, Cursor and any MCP client.
Will I lose credits I do not use?
No. Credits roll over every month while you are subscribed, so a light month never wastes what you paid for.
Is Pixel Dojo free to try?
Yes. A free account gets 3 free effects every day, no card needed. Plans from $10/mo unlock every model, every studio and Sensei, with Unlimited on every plan.
