Why Choose This?
-
Turbo speed Faster processing than the Pro version — ideal for rapid prototyping and batch workflows.
-
Seamless continuation AI analyzes motion patterns and scene context to generate frames that flow naturally.
-
Guided extension Optionally upload an end-frame image to steer where the video should go.
-
Prompt control Add text descriptions to guide the extended content’s direction and style.
-
Flexible duration Extend videos by 1 to 7 seconds at a time.
-
Multiple resolutions Output in 540p, 720p, or 1080p to match your quality needs.
Parameters

Best Use Cases
- Quick iterations — Rapidly test extension ideas before committing to Pro quality.
- High-volume workflows — Process many videos efficiently.
- Draft previews — See how extensions look before final rendering.
- Social media content — Fast turnaround for time-sensitive posts.
- Loop creation — Extend videos for seamless looping content.
Pro Tips
- Use Turbo for testing, then switch to Pro for final quality if needed.
- Higher quality source videos produce better extensions.
- Use the guidance image to control the endpoint of your extension.
- Prompts help when you want specific actions in the extended portion.
- For longer extensions, run multiple passes.
Notes
- Video is the only required field.
- Maximum extension: 7 seconds per run.
- For longer extensions, process in multiple passes.
- Ensure uploaded file URLs are publicly accessible.
