MiniMax-H3 Reference to Video
MiniMax-H3 reference-to-video: drive generation with reference images, and optionally a reference video and reference audio.
ref_imgs— 1–9 images, required. Number them in your prompt as<Picture 1>…<Picture 9>.ref_videos— 0–1 video, optional. Referred to as<Video 1>.ref_audios— 0–3 audio clips, optional. Numbered<Audio 1>…<Audio 3>.
The number in each tag is the item’s position in its own array, starting at 1.
Only the first 15 seconds of each reference video or audio clip is used. A reference video is far heavier to process than images, so a request that includes one takes noticeably longer to render — the price is unchanged.
First/last frames are not supported here; use the hailuo_h3 model for those.
Pricing — billed per second, by resolution:
| Resolution | Tokens / sec | USD / sec |
|---|---|---|
| 480p | 1.5 | $0.03 |
| 720p | 3 | $0.06 |
| 2K | 4.5 | $0.09 |
All resolutions support 5–15 seconds. 2K renders at 720p first and is then upscaled, so it takes longer than 720p.
Returns an img_uuid; poll GET /api/v1/jobs/detail (or use custom_callback_url) to get the generated video.

Body
application/json
Model name. Must be hailuo_h3_refs.
Available options:
hailuo_h3_refs Text prompt describing the video. Required. Max 7000 characters. Refer to reference material by position: <Picture 1> … <Picture 9>, <Video 1>, <Audio 1> … <Audio 3>.
Maximum string length:
7000Reference images, 1–9 URLs. Required. JPG/PNG/WEBP, ≤10MB each, shortest side ≥300px. Array order defines the <Picture N> numbering used in the prompt.
Required array length:
1 - 9 elementsReference video, 0–1 URL. Optional. Only the first 15 seconds are used. Referred to as <Video 1> in the prompt. Including one makes the request noticeably slower to render; the price is unchanged.
Required array length:
1 elementReference audio, 0–3 URLs. Optional. Only the first 15 seconds of each are used. Array order defines the <Audio N> numbering used in the prompt.
Required array length:
1 - 3 elementsOutput resolution. This also selects the price — see the pricing table. 2K renders at 720p first and is then upscaled, so it takes longer.
Available options:
480p, 720p, 2K Video duration in seconds. Any integer from 5 to 15.
Required range:
5 <= x <= 15Aspect ratio of the output video. Unlike the hailuo_h3 model, reference-to-video always uses this value (there is no input frame to follow).
Available options:
16:9, 9:16, 1:1, 4:3, 3:4, 3:2, 2:3 Optional. A publicly accessible HTTPS URL. When the task status changes (processing / success / failed), GoEnhance sends a POST request to this URL. The request body is identical to the response of GET /api/v1/jobs/detail. If your server does not respond with HTTP 200, the notification is retried up to 3 times, with a 3-second timeout per attempt.
Example:
"https://your-server.com/goenhance/callback"
