MiniMax / MiniMax H3 Reference To Video#

Minimax H3 Reference to Video generates a 768p, 2K clip from a text prompt and the reference media you attach. Supply at least one reference image or video, describe the scene you want, and the model works out how your references should behave on screen.

The split is simple. Images pin what things look like; videos pin how things move. Minimax H3 Reference to Video reads both against your prompt rather than treating either as a fixed template.

Highlights#

• Reference-guided generation: Minimax H3 Reference to Video conditions on real media, not prompt wording alone, which keeps a subject recognizable from shot to shot.

• Up to nine reference images: Lock a face, a product detail, or a visual style across a sequence of Minimax H3 Reference to Video shots.

• Up to three reference videos: Give Minimax H3 Reference to Video existing footage when movement or camera behavior matters more than the look.

• Optional reference audio: Up to three files, but audio cannot be sent on its own.

• 768p, 2K output: Choose 768p for cheaper drafts or 2k when detail needs to hold up in large placements.

• Six aspect ratios: 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16 cover widescreen, square, and vertical deliverables.

• Adjustable length: Minimax H3 Reference to Video runs any whole number of seconds from 4 to 15.

How to Use#

1) Attach your references — Add images that define the subject and, if movement matters, clips that define it. Minimax H3 Reference to Video needs at least one of the two.

2) Write the brief — Describe the action, camera work, lighting, and mood.

3) Say how the references relate — Name which one supplies the subject and which supplies the motion. Minimax H3 Reference to Video follows an explicit relationship far better than an implied one.

4) Add reference audio (optional) — Only alongside an image or video reference in Minimax H3 Reference to Video.

5) Pick the aspect ratio — 16:9 widescreen, 9:16 vertical, 1:1 square, 21:9 wide cinematic.

6) Choose resolution and length — Start at 768p and a short duration while testing, then switch to 2k and extend toward 15 seconds once Minimax H3 Reference to Video is behaving.

7) Generate and refine — Change one reference or clause at a time so you can attribute the difference in the Minimax H3 Reference to Video output.
