Why Creators Choose MiniMax H3 Max Recast
Nothing here is generated from scratch. Your clip keeps its performance and its soundtrack; the portraits you upload simply take over the identities you see on screen.
- A casting change, not a new renderMotion, framing, edit points and audio all survive the pass — the only thing that changes is who appears on screen.
- Up to four performers, matched left to rightEach portrait pairs with one person in the frame, running left to right by default. A short prompt re-pairs them whenever that default lands wrong.
- The source clip directs the performanceGaze, head turns, timing, expressions, set lighting and lens character are inherited from the original footage, while faces and wardrobe come from your uploads — and the same performer is followed across cuts.
How to Use MiniMax H3 Max Recast in 3 Steps
Upload a take that already works, add one portrait per performer, review the swap at 768p, then render the final version at 1080p.
Core Capabilities of MiniMax H3 Max Recast
Built for casting rather than creation: the original motion, edits and sound are protected, only the on-screen performers change, and a 768p preview comes before the 1080p render.
Four-person casting, ordered left to right
Upload up to four portraits and they take over the lead performers in every shot, matched left to right by default. A line such as 'the woman on the right becomes person 1' overrides the pairing.
Body language and expressions carry over
Where the eyes look, how the head turns, comic timing, facial expression, set lighting and lens behaviour are all inherited from the original take; only faces and clothing come from your photos.
Cuts and soundtrack stay untouched
The existing edit pattern and audio bed are kept, so the finished recast drops straight into a locked cut — no re-editing and no re-recording.
Face-only mode when styling has to hold
Without guidance the model often borrows hair and garments from the portrait, even a tight headshot. Asking for a face-only change keeps the original styling — we confirmed this in our 23 October 2026 test.
Low-cost preview, 1080p delivery
A fast 768p pass tells you whether the casting reads correctly before you commit to 1080p. Runtime follows the source, so cost scales with clip length.
Proven on very different footage
Test recasts cover a music-video close-up, a barista spot, a fencing bout, a skate launch and a dawn fish market — each holding its own motion, edits and audio.
MiniMax H3 Max Recast — Common Questions
Everything you need to know before your first MiniMax H3 Max Recast run.
How does a recast differ from generating a new video?
Generation creates footage from nothing. Here the footage already exists: the people in your photos replace the performers, while motion, camera work, cuts and audio stay as they were shot.
How long can the source clip be?
Between 5 and 30 seconds, with no single shot longer than 15 seconds — split longer takes first. The recast runs exactly as long as the input.
How many people can be replaced, and in which order?
Up to four, one photo each. Portraits take over the leading performers left to right across the frame by default, and a prompt can re-pair them if that order is wrong.
Which reference photos give the best results?
Sharp, evenly lit, front-facing portraits, one per person. Avoid sunglasses, hats, hands over the face, group shots, and low-resolution or heavily filtered images. If the original hair and wardrobe must survive, request a face-only swap.
768p or 1080p — which should I pick?
Preview at 768p to check that the casting reads correctly, then render at 1080p for delivery. Cost follows clip length.
When is this tool the wrong choice?
It cannot invent new action, new camera work or a new location — the source decides those. Crowded scenes, small or distant faces, fast movement and occlusion after hard cuts weaken results, and identity can drift back toward the original performer in wide shots or profile turns.
