What people use it for
Social ad draft
Turn a product image, a short reference clip, and a 15‑word prompt into a 10-15s ad-ready clip with background audio and the same camera movement as your reference. Outcome: a shareable MP4 ready for platform upload and A/B testing.
Campaign creative variations
Upload a brand portrait and two style images, then generate multiple 6-12s variants that keep the subject consistent while changing color grading and motion. Outcome: a set of quick variants for creative review and select-and-scale.
Trailer or teaser clip
Provide a first-frame image and a reference video for camera pacing, add a music track, and produce a 15s teaser with native audio sync and defined first/last frames. Outcome: a polished short teaser suitable for reels and stories.

- Faster generation for low-latency drafts using the Fast variant.
- Accepts multi-input references: images, short videos, and audio tracks.
