MiniMax-H3 Key Features
MiniMax-H3 (Hailuo 3) is a general-purpose multimodal video model built for commercial content creation.
Native 2K Resolution
MiniMax-H3 renders true 768P and 2K output — not an upscale pass — so clips stay sharp on large screens and client deliveries.
Synced Audio Track
Dialogue, SFX and atmosphere are generated with the picture in one pass. Every MiniMax-H3 video ships with sound built in.
Multimodal References
Guide generation with up to 9 reference images, 3 reference videos and 3 reference audios — character, motion and voice stay consistent.
First & Last Frame Control
Anchor the exact opening and closing frames. MiniMax-H3 fills the in-between motion for precise transitions and loops.
4–15 Second Clips
More room than a typical short hook: an open, a product moment and a close fit in a single MiniMax-H3 generation.
Six Aspect Ratios
21:9, 16:9, 4:3, 1:1, 3:4 and 9:16 — one MiniMax-H3 render covers cinema, feed and vertical platforms.

MiniMax-H3 FAQ
What is MiniMax-H3?
MiniMax-H3 is MiniMax's latest video generation model (the Hailuo 3 series). It creates 4–15 second videos in 768P or 2K from text prompts, images, or multimodal references, and every render includes a generated audio track.
What inputs does MiniMax-H3 support?
Three modes: text-to-video (prompt only), image-to-video with first and/or last frame control, and multimodal reference generation with up to 9 reference images, 3 reference videos and 3 reference audios. Frame control and reference inputs are mutually exclusive.
How many credits does a MiniMax-H3 video cost?
Billed per second: 768P = 29 credits/s, 2K = 46 credits/s. Reference videos stack at the same per-second rate (up to 15s total); the first 5 reference images are free, then a small per-image fee applies.
Does MiniMax-H3 generate audio with the video?
Yes. Dialogue, sound effects and atmosphere are generated in the same pass as the picture — MiniMax-H3 videos ship with a native stereo audio track, no separate sound design needed.
