Muapi의 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 fallback provider 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.

1활용 사례: Multi-subject composition: combine a character and an object/vehicle from separate reference images into one scene

2활용 사례: Character-consistent video: keep a character's appearance consistent across a generated video using a reference photo

3활용 사례: Product-in-scene video: place a product reference image into a generated environment

4활용 사례: Concept mashups: blend visual elements from multiple references into a single coherent video

5활용 사례: Marketing creative: generate branded video content referencing product/character assets

구현 가이드

개발자 문서

Provide 1-9 reference image URLs in images_list (JPEG/PNG/WEBP, ≥400px shortest side, ≤10MB each).
Write a prompt referencing the images by position.
Set resolution to "720p" (cheaper, default) or "1080p" (premium output).
Select aspect ratio, duration (3-15s), and optional seed for reproducibility.
Submit your request—the model composes a video from your references at the selected resolution.

일반적인 질문

자주 묻는 질문

What is the cost of Happy Horse 1.1 Reference to Video?

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.

How is 1.1 different from Happy Horse 1.0?

1.1 is a newer generation with improved reliability (automatic fallback provider) and lower per-second pricing at both resolutions.

How do I choose the resolution?

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

How many reference images can I use?

1 to 9 images, referenced in your prompt matching the order in `images_list`.

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.
