Aspect Ratio(string)

The aspect ratio of the generated image. Allowed values: 21:9, 16:9, 3:2, 4:3, 5:4, 1:1, 4:5, 3:4, 2:3, 9:16.

Video URL(string)

The URL of the video to reframe. Must be publicly accessible or a base64 data URI. The video is re-cropped to the target aspect ratio and the newly exposed areas are filled with generated content that matches the original. Max duration 60 seconds.

Resolution(string)

The target output resolution tier. Combined with the aspect ratio to determine the output size. Allowed values: 720p, 1080p.

Async Workflow

This model uses asynchronous execution. Submit a request and poll for the result.

Submit — POST to /v1/run, receive an id
Poll — GET /v1/run/{id} until status is completed, failed, or timeout
Retrieve — Read outputs from the completed response
