Om denna modell

Uppdaterad 11 sep. 2026

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

Vanliga frågor

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.
