Capabilities
What you can make with MiniMax H3
Shots that need a camera, a performance and a soundtrack - all three arriving in the same render.
2K straight out of the model
Output at 768p or a full 2K tier, so a hero shot reaches delivery resolution in the first render instead of going through an upscale pass afterwards.
Audio with no switch to forget
Dialogue, ambience and effects come back with every clip. There is no audio toggle on H3 because there is no silent mode - you never discover a mute render after paying for it.
Expressive character motion
The strength MiniMax's video line is known for: faces that act, hands that behave, and full-body movement that keeps its weight instead of sliding through the frame.
First frame, last frame, five references
In image-to-video mode, pin the opening frame, chain to a closing one, or pass up to five reference images to hold a character or product steady. The render follows your source image's framing.

Where it fits
How people use MiniMax H3
The pick when a person has to carry the shot - and when the clip has to sound finished, not just look it.
Talking-head and dialogue
A line delivered to camera with lip-sync and room tone already in place, ready to cut without a separate audio pass.
UGC-style social ads
9:16 hooks with a presenter, a product and sound - the format that needs a believable human more than it needs resolution.
Product film at 2K
Hero shots and feature reveals rendered at the 2K tier for landing pages and paid placements that will be viewed full-width.
Draft on H3 Max, finish on H3
Block the shot on the cheaper 480p tier, then re-render the take you like on H3 at 2K. Both are one click apart in the same picker.

Questions, answered
Frequently asked
- What is MiniMax H3?
- MiniMax H3 is MiniMax's flagship video model — the lab whose earlier video releases you may know as Hailuo. It turns text prompts or images into clips of 5 to 15 seconds with audio generated alongside the picture, at 768p or 2K, and it is in DreamFort's Video Studio picker for both text-to-video and image-to-video.
- What's the difference between MiniMax H3 and H3 Max?
- H3 is the quality tier: 768p or 2K, and up to five reference images in image-to-video. H3 Max is the fast, cheaper sibling at 480p or 768p - no 2K tier, and it takes a first and last frame but no reference images. Same aspect ratios, same 5-to-15-second durations, same native audio on both. Use H3 Max for drafts and volume, H3 for the render you ship.
- How do I use MiniMax H3 on DreamFort?
- Open DreamFort's Video Studio from the button on this page — it lands with MiniMax H3 preselected. Type a prompt (or upload an image in image-to-video mode), pick an aspect ratio and duration, and generate. The studio is visible without an account; generating takes a free sign-up.
- Does MiniMax H3 always generate sound?
- Yes. Audio is part of the render rather than an option on it, so every H3 clip comes back with dialogue, ambience and effects. Models with an audio toggle can be rendered silent; H3 can't.
- Can MiniMax H3 animate an image?
- Yes - image-to-video is in the same picker, with first-frame and last-frame control and up to five reference images for consistency. There's no aspect-ratio picker in that mode: the output follows the framing of the image you upload.
- How long can a MiniMax H3 clip be, and how long can the prompt be?
- Clips run 5, 6, 8, 10, 12 or 15 seconds. Prompts run to 7,000 characters, which is enough for a timestamped shot list with camera, lighting and audio direction rather than a one-line description.
- What does a clip cost?
- Per-clip prices depend on the model and duration and are shown before you generate. 1,000 credits = $1; packs start at $10; you get free credits to start - no card needed.
- How does MiniMax H3 compare to Seedance, Veo, Kling and Wan?
- H3 is the character-and-audio specialist: sound is part of every render rather than an option on it, and its second resolution tier is a full 2K. Seedance 2.5 goes longest in one take, Veo 3.1 pushes resolution to 4K, Kling v3 Pro leads on motion fidelity, and the Wan line runs unrestricted. They share one model picker on DreamFort, so you can audition the same prompt across all of them for cents.
