MiniMax H3 on VisionX.
Up to 2K, refined from a native 768p render, in one take of up to fifteen seconds with sound.
What MiniMax H3 is on the roster
MiniMax H3 renders natively at 768p and delivers up to 2K by refining that render in a second pass, so a keeper leaves as a 2K master without a separate finishing job. Its 720p tier is the native 768p render itself, for drafts.
It is also unusually flexible about what it will take direction from. A shot can open on a frame you supply and close on another, or it can be built from references — up to nine images for subject and wardrobe, three clips for camera rhythm, and voice tracks for delivery — with a generated audio track on the way out.
2K from a native 768p render
The 2K tier refines the native 768p render to 2K in a second pass. Block the shot at 720p, then run the keeper at 2K.
Fifteen seconds in one take
Any length from four to fifteen seconds, as a single continuous shot, so a beat that needs room does not have to be stitched from two renders.
Open and close on your frames
A first frame, a last frame, or both. The output inherits their geometry, which makes it the straightforward way to bridge two stills you already have.
References for subject, motion and voice
Nine reference images, three reference clips and three voice tracks, addressed positionally in the prompt — the character from Image 1 moving to the camera rhythm of Video 1.
Widescreen included
H3 renders true 21:9 as a first-class ratio rather than cropping a 16:9 frame down to it.
What MiniMax H3 actually does
A 2K tier, one take up to fifteen seconds, and the references that brief it.
2K from a native 768p render
H3 renders natively at 768p, which is the 720p tier for drafts. The 2K tier refines that render to 2K in a second pass, so a keeper leaves as a 2K master without a separate finishing job.
2KAny length from four to fifteen seconds
One continuous take, set to the second, so a beat gets the room it needs instead of being stitched from two renders.
Single takeOpen and close on your frames
A first frame, a last frame, or both. The output inherits their geometry, which makes H3 the straightforward way to bridge two stills you already have.
First and last frameNine stills, three clips, three tracks
Up to nine reference images, three reference clips and three audio tracks, twelve references at most in one shot, each addressed by number in the prompt.
Multimodal referenceSound on every take
H3 generates an audio track with the picture on every render, and on VisionX there is no silent mode, so plan to replace the track in the edit when the cut is scored.
Native audioTrue 21:9
Widescreen 21:9 is a first-class ratio alongside 16:9, 4:3, 1:1, 3:4 and 9:16, rather than a 16:9 frame cropped down to it.
AspectEvery variant, exactly as the studio runs it
These rows are read live from the engine registry and the pricing engine. What you see here is what the composer quotes.
Self-serve rates run as low as $0.085 per VX at scale. The composer quotes the exact VX for your shot, references included, before you run it.
How to write for MiniMax H3
H3 reads references by type and number, so the prompt’s job is to say what each one is for. Everything else is ordinary shot description.
Image 1 is the watch. Image 2 is the wrist and sleeve. Video 1 carries the camera move: a slow orbit, then a push. The watch from Image 1 on the wrist from Image 2, turning into low raking light. The move follows Video 1 and settles on the dial.
Address references by number
“Image 1”, “Video 1”, “Audio 1”, in the order you attached them. Naming what each one contributes beats “in the style of”.
Audio needs a picture beside it
A voice or audio reference cannot brief a shot on its own. Attach at least one image or clip with it.
Save 2K for the keepers
Block the shot on the 720p tier until the staging is right, then re-run the approved prompt at 2K.
Keep the brief under 7,000 characters
That is H3’s own prompt ceiling, and the composer counts against it as you write.
What teams route to MiniMax H3
The board lines that go to H3 first.
Deliverables that ship at 2K
Product close-ups, packaging and title cards that leave the render as a 2K master.
Bridging two approved stills
A first and a last frame from signed-off key art, with the move generated between them.
A shot with a voice brief
The Cast member from an image, the delivery from a voice track, the camera rhythm from a clip.
Cinematic widescreen
Title cards and brand films framed at 21:9 from the first render.
Same Cast, same wallet, different look
Route a board line to MiniMax H3, then run the identical shot on another family and compare takes. Identity lives in your Cast, not in any one model, so switching engines never strands the campaign.
