Best Use Cases

  • Extend short clips — Add more runtime to clips that ended too soon.
  • Smooth transitions — Generate bridge content between scenes.
  • Loop creation — Extend videos for seamless looping content.
  • Creative exploration — See where AI takes your video next.
  • Content padding — Reach minimum duration requirements for platforms.

Pro Tips

  • 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 or elements in the extended portion.
  • For longer extensions, run multiple passes (extend, then extend again).
  • Match resolution to your source video for best consistency.

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.
