What is MiniMax H3 Highspeed?

MiniMax H3 Highspeed is a faster version of MiniMax H3 that balances quality and speed. It renders 768p video at 24 fps with native audio, runs 4 to 15 seconds per generation, and takes the same inputs as H3: text alone, a start frame with an optional end frame, 1 to 9 reference images, or up to 3 reference videos. It is the model for everyday content where 2K output is not needed and turnaround matters.

Key features of MiniMax H3 Highspeed

Same inputs as H3

Text-to-video, start frame with optional end frame, reference images and reference videos all work the same way as on H3, so a prompt tuned on H3 Highspeed moves to H3 unchanged when you need 2K.

Built for speed at 768p

A faster H3 build with one output resolution, 768p, in six aspect ratios. With a frame image, output follows the input frame shape.

Reference-to-video

Pass 1 to 9 reference images and name them in the prompt as @Image1 through @Image9. The model keeps the subject consistent across generations and can combine a character, a product and a location in one shot. Reference images cannot be combined with start/end frames in one request.

Reference videos

Up to 3 reference videos, 15 seconds in total, passed in video_urls. Each second of uploaded video is billed at the per-second output rate.

Native audio in the same pass

Output arrives with an audio track generated alongside the picture, no separate audio step.

What MiniMax H3 Highspeed is best for

  • Everyday content

    Publishable 768p clips with sound without waiting on a 2K render.

  • Batches of social clips

    Fast turnaround on 9:16 and 1:1 clips with native audio.

  • Character-locked series

    Reference images keep the same character across every video in a campaign.

  • Reference-video edits

    Carry the motion or style of a short reference video into a new 768p shot.

MiniMax H3 Highspeed use cases

Produce a week of 9:16 social clips with sound in one batch at 768p. Put a product into a new scene by passing the product and the location as two reference images. Animate a still from a start frame, or pin both ends of the shot with a start and an end frame. Pass a short reference video to carry its motion or style into a new shot.

MiniMax H3 Highspeed limitations

H3 Highspeed outputs 768p only; for 2K use MiniMax H3, and for the cheapest 480p drafts use H3 Lite. It takes no seed, prompt expansion level or reference audio; H3 Fast and H3 Max do. Reference images and frame images are mutually exclusive in one request, and an end frame needs a start frame. Duration is capped at 15 seconds per generation and reference videos at 15 seconds in total.
