- Write your prompt — describe the motion, action, or scene development after the current ending.
- Set quality — match the resolution of your source video for consistent output.
- Set duration — choose how many seconds to add (1-15).
- Set seed (optional) — fix a seed to reproduce the same extension result.

Best Use Cases
- Short-form Content — Extend social media clips that ended too soon.
- Cinematic Scenes — Prolong a cinematic shot for more dramatic effect.
- Product Videos — Add extra seconds to showcase more product detail.
- Story Continuations — Let a narrative scene play out further than the original.
- Looping Content — Generate additional footage to create longer loop-ready clips.
Pro Tips
- Match the
qualitysetting to your source video resolution for the best visual consistency. - Be specific in the prompt about what should happen next — vague prompts produce generic continuations.
- Use short extensions (1-3s) for subtle continuations and longer ones (8-15s) for significant scene developments.
- Fix a
seedvalue when iterating on prompt wording so you can compare continuations fairly. - Ensure the source video URL is publicly accessible before submitting.
