FAQ

Can I use `/v1/videos`?

No. MiniMax H3 is available only on the native /hailuo/v2 endpoints. Requests to /v1/videos or /v1/video/generations are rejected without charge.

How long does a video take?

A 4–5 second 768P video usually finishes in about a minute; 2K and reference-video tasks take longer. At busy times a task may show queued first and then start automatically in submission order, so there’s no need to resubmit.

Is it the same as MiniMax’s official API?

It runs MiniMax’s open H3 weights and accepts the same text, image, video, and audio inputs as the official MiniMax-H3, with 768P and 2K output and a soundtrack. Because the route is deployed independently, it has its own pricing, and generation speed can differ from the official API.

Do videos have a watermark?

No visible watermark. Each clip has a stereo soundtrack whose music and effects follow the prompt.
