MiniMax H3 Max Recast: New Faces, Same Performance
This tool begins with a video that is already done. The clip provides the acting, the timing and the soundtrack; the portraits you upload provide the new line-up of faces.
- Nothing is regenerated — only the facesEvery strength the source already has, from body language and framing to the edit rhythm and the final mix, carries through. The single thing that changes is who appears on screen.
- Up to four portraits, mapped across the frameOne photo per performer, and by default the pairing runs from the leftmost face in the shot to the rightmost. When that order is wrong, a single line of text re-pairs them.
- The performance comes from the source clipEye lines, head turns, beats, expressions, set lighting and lens character are read from the original footage; faces and clothing come from your uploads, and the same performer is followed across scene changes.
MiniMax H3 Max Recast: Three Steps From Upload to Render
Upload a cut you are happy with, attach one portrait per person, run a quick 768p check, then render the final version at 1080p.
What H3 Max Recast Does Under the Hood
Built for casting rather than generation — the source clip's movement, edit structure and mix are protected, only the people are exchanged, and a 768p pass lets you check the result before the 1080p render.
Four performers, matched left to right
As many as four portraits can take over the leading performers in each shot, paired across the frame by default. A phrase such as 'the woman on the right becomes person 1' overrides that pairing.
Gesture and expression come from the take
Eye direction, head turns, comic timing, facial expression, set lighting and lens character are all inherited from the original footage; only the face and wardrobe are drawn from your photos.
Cuts and soundtrack are left alone
The existing edit pattern and mix are kept, so the finished recast drops straight into a locked timeline without a re-edit or a re-record.
Face-only mode when the styling has to hold
Left to its own devices, the model tends to borrow hair and clothing from the portrait, even a tightly cropped headshot. Asking for the face alone keeps the original styling — confirmed in our 23 October 2026 run.
Low-cost 768p preview before the 1080p render
A fast 768p pass shows whether the casting reads correctly before you commit to 1080p. Runtime matches the source, so cost scales with how long the clip is.
Tried on very different kinds of footage
Sample recasts range from a music-video close-up and a barista commercial to a fencing bout, a skate launch and a fish market at dawn — each keeping its own movement, edit pattern and sound.
MiniMax H3 Max Recast: Questions Creators Ask
Answers to common MiniMax H3 Max Recast questions.
What separates a recast from plain video generation?
Generation invents footage from nothing. A recast starts from a clip you already have: the people in your photos take over the on-screen roles, while movement, camera work, edit pattern and audio are inherited from the original file.
What length of source video is allowed?
Between 5 and 30 seconds, with no single shot longer than 15 seconds — cut longer takes apart first. The finished recast lasts exactly as long as the input.
How many performers can I swap, and in which order?
Up to four, one photo each. By default the portraits take over the leading performers from left to right across the frame; a prompt can re-pair them if the default is wrong.
Which portraits give the best results?
Sharp, evenly lit, straight-on headshots, 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.
Do I preview at 768p or go straight to 1080p?
Run the 768p pass first to confirm the casting reads correctly, then render at 1080p for delivery. Pricing follows the length of the clip.
Where does this tool reach its limits?
It cannot invent new action, new camera work or a new location — the source decides those. Results weaken in crowded scenes, with tiny 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.
Put MiniMax H3 Max Recast to Work on Your Next Cut
Hand over a clip that is already finished, add portraits for the new cast, and let the swap run — pacing, camera work, edit points and audio remain as recorded.
