Extending Your Videos
Make a short clip longer — continue an existing video seamlessly to build longer sequences, loops and trailer shots.
A single generation gives you a short clip. When you need something longer — a drawn-out establishing shot, a background loop, a trailer beat — you extend the video: the generator continues from where your clip ends, adding more motion onto the tail.
When to extend
- Your clip is great but ends too soon.
- You want a longer, continuous shot without a visible cut.
- You're building a background loop and need more runway before it repeats.
Step 1 — Start from a clip you like
Extend works from an existing video, so generate (or bring in) a clip you're happy with first. The extension continues its motion and look, so a clean, on-style starting clip makes for a clean extension. If your base clip already drifts or warps, fix that before extending — the problems only compound.
Step 2 — Extend it
Choose to extend the clip. The generator picks up from the final frames and continues the motion, giving you a longer result. You can guide the continuation the same way you guide any clip — describe how the motion should carry on (keep drifting, slow to a stop, push in further).
Step 3 — Check the seam
Play the full result and watch the point where the extension begins. A good extension is invisible; if you can see a jump, regenerate the extension or ask for a gentler continuation. Consistent, subtle motion extends far more cleanly than fast action.
Step 4 — Repeat to build length
Extend again from the new, longer clip to keep going. Chaining extensions lets you build a genuinely long shot a beat at a time — just review the whole thing after each pass so small drifts don't accumulate.
Looping vs. lengthening
- Lengthening — extend to make a longer one-way shot (trailers, establishing beats).
- Looping — extend just enough that the end returns near the start, then loop it behind a menu or scene.
