Features
- Any Clip Works——AI-generated 5-second clips or half-shot phone footage — MP4, MOV or WebM up to 100MB, vertical or horizontal.
- Seamless Continuation——Same person, same light, same camera move — the joint holds up even when you scrub through it slowly.
- Extend Either Direction——Continue forward, add a lead-in backward, or do both at once — and relay in passes toward tens of seconds.
- One Sentence Is Enough——Leave the box empty and the default finishes the move; write what happens next and you direct the ending.
How it works

- Say What Happens Next Write what happens next, pick a preset, or choose direction, length and style. Leaving it empty works too.
- Export One Seamless Video Same person, same light, seconds longer. Relay further for more, or polish it with HD enhancement.
FAQ
- Free? Do I need to sign in?
- Free to try. Uploading, describing and browsing cases cost nothing — sign in when you hit Generate and you are working, no membership needed.
- How many seconds does extend video with AI add?
- A few seconds per pass is steadiest. For a dozen-plus seconds, relay pass by pass: finish one stretch, then continue from it into a full scene.
- Can I extend video with AI from a photo?
- Yes, in two steps: first turn the photo into a few seconds of motion, then extend. Use a sharp front-facing photo, a centered subject and a clean background, one or two small moves at a time.
- Extend video with AI vs expand: different?
- Different. Extending adds time (new seconds of footage); expanding adds area (edge pixels). For portrait-to-landscape reframing, use another tool.
- Will the extended part glitch?
- Small moves plus short passes rarely glitch: continue the current action, a few seconds at a time, locked to the same scene. Close-up faces with big moves are the risky combo — extend twice and keep the steadiest take.
- Can I upload phone footage?
- Yes. MP4, MOV or WebM under 100MB — phone-shot and AI-made clips extend the same way, vertical first, horizontal fine too.
- Runway or Pika instead?
- Any outside video uploads here, nothing locked to in-site generations, and the description box stays open without paying to unlock. Upload and extend in three steps, right on your phone.
