このモデルについて
Happy Horse 1.1 Reference to Video generates video conditioned on 1-9 reference images plus a text prompt, at your choice of 720p or 1080p output resolution, with improved reliability over Happy Horse 1.0 via an automatic KIE.ai fallback path. Reference multiple images in your prompt to compose scenes combining characters, objects, and settings from separate source images.
A single resolution parameter lets you draft cheaply at 720p and switch to 1080p for final output on the same endpoint.

Happy Horse 1.1 Reference to Video costs $0.14/sec at 720p (default) or $0.18/sec at 1080p on muapi. A 5-second 720p clip costs $0.70; the same clip at 1080p costs $0.90.
1.1 is a newer generation with improved reliability (automatic KIE.ai fallback) and lower per-second pricing at both resolutions.
Pass `resolution: "720p"` (default) or `resolution: "1080p"` in your request body — both are served by the same endpoint.
1 to 9 images, referenced in your prompt matching the order in `images_list`.
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.
