Why Use MiniMax H3 Max Recast
The clip you bring already carries the performance and the soundtrack. Your uploaded portraits simply take over the roles, so nothing else in the edit has to be rebuilt.
- A casting change, not a new shootFraming, pacing, transitions and sound are all carried over from the source. The only thing that changes is who appears on screen.
- Up to four roles, read left to rightEvery portrait is assigned to a performer, and the default assignment follows the frame from the leftmost figure to the rightmost. One short instruction is enough to remap the pairs when that order is wrong.
- The original take directs the actingHead turns, eye lines, timing, expressions, set lighting and lens character stay with the source clip, while faces and outfits come from your photos — and each performer is followed across scene changes.
How to Use MiniMax H3 Max Recast
It takes three moves: choose a clip that is already final, upload one portrait per performer, then check a 768p preview before exporting at 1080p.
MiniMax H3 Max Recast Features
Built for recasting rather than generating: motion, edit points and sound in your footage are protected, only the performers change, and a 768p preview comes before the 1080p export.
Four roles, matched left to right
Up to four portraits can be uploaded, and by default they take over the leading performers in each shot in left-to-right order. A phrase such as 'the woman on the right becomes person 1' remaps the pairing.
Motion and expressions carry through
Eye lines, head turns, comic timing, facial expression, set lighting and lens behaviour are inherited from the original take; only faces and wardrobe are pulled from your photos.
Cuts and soundtrack remain untouched
The existing edit pattern and audio track survive the swap, so the output drops directly into a finished timeline without a re-edit or a re-record.
Face-only mode when styling must hold
Without guidance, the tool often borrows hair and clothing from the portrait — even a tightly cropped headshot. Requesting a face-only change keeps the original styling, as confirmed in our 23 October 2026 run.
Low-cost preview, 1080p final render
A fast 768p pass reveals whether the casting reads correctly before you commit to 1080p. Runtime follows the source clip, so cost scales with its length.
Proven across very different footage
Sample recasts range from a music-video close-up and a barista commercial to a fencing bout, a skate launch and a dawn fish market — each retaining its own motion, cuts and sound.
MiniMax H3 Max Recast — FAQ
Answers to the questions people ask most about MiniMax H3 Max Recast.
How does recasting differ from generating a video from scratch?
Generation creates footage that never existed. MiniMax H3 Max Recast starts from a clip you already have: the people in your photos take over the roles, while movement, camera work, edit points and audio all remain from the original.
What length of source video is supported?
Between 5 and 30 seconds, with no single shot longer than 15 seconds. Split longer takes into pieces first. The recast output is exactly as long as the input.
How many performers can be replaced, and in which order?
Up to four, each with one photo. Portraits are matched to the leading performers left to right across the frame by default, and a prompt can reassign the pairing if that default is off.
Which reference photos give the best results?
Sharp, evenly lit, straight-on 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 stay, ask for a face-only replacement.
Should I preview at 768p or go straight to 1080p?
Preview at 768p to confirm the casting reads correctly, then render at 1080p for delivery. Pricing is based on the length of the clip.
When is this tool the wrong choice?
It cannot invent new action, new camera work or a different location — the source dictates those. Results weaken with crowded scenes, small or distant faces, fast movement and occlusion after hard cuts, and identity can drift back toward the original performer in wide shots or profile turns.
