How it works
Describe the clip
Write what should happen in 5 seconds: the subject, the style, the camera move. The prompt stays attached to the render, so you can see what made each clip.
We render it
An open-weights model on GPUs we operate turns the prompt into a 540x960 portrait clip, most of the time in 2-5 minutes. A failed render is refunded.
Download and publish
One MP4, no watermark, yours to publish anywhere, commercial use included. Pay $1 for the clip; nothing recurring.
