Happy Horse 1.0 Video Edit modifies an existing video using a natural-language instruction, with optional reference images to guide the edit, at your choice of 720p or 1080p output resolution. Describe the change you want (swap a subject, restyle the environment, adjust an object) and the model applies it while preserving the original motion and camera work.

A single resolution parameter lets you draft cheaply at 720p and switch to 1080p for final output on the same endpoint.

1Subject replacement: swap a person, animal, or object in an existing video for something else

2Environment restyling: change the setting/background of a video while preserving action and camera motion

3Style transfer edits: apply an artistic or thematic restyle to existing footage

4Asset localization: swap in branded assets/products into existing video content

5Creative remixing: reimagine existing footage with new visual elements guided by reference images

Sık Sorulan Sorular

Sık sorulanlar

What is the cost of Happy Horse 1.0 Video Edit?

Happy Horse 1.0 Video Edit costs $0.21/sec of input video at 720p (default) or $0.42/sec at 1080p on muapi. A 10-second source video costs $2.10 at 720p or $4.20 at 1080p.

How do I choose the resolution?

Pass `resolution: "720p"` (default) or `resolution: "1080p"` in your request body — both are served by the same endpoint.

What video formats are supported?

MP4 or MOV (H.264 recommended), 3-60 seconds, up to 100MB, longer side up to 2160px, shorter side at least 320px, frame rate above 8fps.

What does audio_setting control?

"auto" lets the model decide how to handle audio for the edit; "origin" preserves the source video's original audio track.

What happened to the dedicated 720p/1080p endpoints?

They still work exactly as before, unchanged, for existing integrations. This unified endpoint is the new recommended way to access both resolutions through one integration.
