Questions
H3 Max Recast, answered
- What is H3 Max Recast?
- H3 Max Recast is a video editing model from MiniMax. Recasts the people in a video from up to four photos, one per person, left to right, keeping the motion, camera, cuts and sound. Billed by the length of the video. It is new on Leap and in preview: it works, and it may still change. On Leap it runs in one studio beside every other top model, with one account.
- Can H3 Max Recast start from a photo?
- Yes. H3 Max Recast starts from words, up to 4 reference images or a video.
- What resolution and sizes does it make?
- Up to 1080P.
- How much does a run cost?
- It costs $0.56 a second of your video. You see the exact price before you press go, and a run that fails costs nothing.
- Is H3 Max Recast free to try?
- No. There is no free credit: you add credit from $5, and your first top-up has no card fee. It costs $0.56 a second of your video. You pay per run, in dollars, with no subscription.
- Can I use what I make commercially?
- Yes. You own what you make on Leap, so you can use it commercially, and we never train AI on it. The people and brands shown in a result can still have rights in it; the Terms say more.
- Is there an API?
- Yes. Leap's REST API runs it as minimax/h3-max-recast, at the same price per run as the studio, and agents can call it through Leap's MCP server. The request is at the bottom of this page.
- Do I need a MiniMax account?
- No. Leap sends your request to MiniMax's model and gives you what it makes. One Leap account runs H3 Max Recast and every other model, in the studio, through the API and from your agents.
Your idea, H3 Max Recast.
Every run shows its price before it starts, and one that fails costs nothing.

The request
The same envelope for every model; only the model and its input change. With prefer: wait=60 the answer holds the result when the run finishes within a minute; a longer one is read again by its ID. A file input takes the ID that POST /v1/files returns for your upload. Agents can call it through the MCP server at app.tryleap.ai/api/mcp.
