What MiniMax H3 Max Recast Does Differently
Everything starts from a clip you have already locked. The footage provides the performance and the soundtrack; the portraits you upload provide the new cast.
- A cast change, not a brand-new renderMotion, framing, edit points and audio in your source are left untouched — only the identities on screen are exchanged.
- Up to four people, mapped left to rightEach portrait is paired with one performer, and by default the pairing runs from the leftmost face in frame to the rightmost. A short prompt re-pairs them whenever the default guess is wrong.
- The performance comes from your footageGaze, head turns, timing, expressions, set lighting and lens character are inherited from the source; faces and wardrobe come from your uploads, and each performer is tracked across scene changes.
Running MiniMax H3 Max Recast in Three Steps
Locked clip, one portrait per performer, then a quick 768p preview before you commit to the 1080p render.
What MiniMax H3 Max Recast Gives You
Built for casting rather than generation: motion, cuts and sound in your source stay intact, only the performers change, and a 768p pass lets you check the result before the 1080p delivery.
Cast up to four people, left to right
Up to four portraits take over the leading performers in each shot, matched left to right by default. A line such as 'the woman on the right becomes person 1' re-pairs them.
Body language and expressions carry over
Gaze, head turns, comic timing, facial expression, on-set lighting and lens behaviour are all inherited from the original take; only faces and wardrobe are drawn from your photos.
Cuts and soundtrack are untouched
The existing cut pattern and soundtrack survive, so the recast drops straight into a finished edit without a re-edit or a re-record.
Face-only mode when the styling must hold
Left unprompted, the tool tends to borrow hair and clothing from the portrait, even from a tight headshot. Asking for a face-only change keeps the original styling — confirmed in our 23 October 2026 run.
Low-cost preview, 1080p final
A fast 768p pass shows whether the casting reads correctly before you pay for 1080p. Runtime follows the source, so cost tracks clip 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 fish market at dawn — each keeping its own motion, edits and sound.
MiniMax H3 Max Recast: Questions Answered
Quick answers on casting limits, clip length, photo quality and when a recast is the wrong tool.
What makes a recast different from generating a video?
Generation invents footage from scratch. MiniMax H3 Max Recast works on footage you already have: performers are replaced by the people in your photos, while movement, camera work, edit points and audio stay as they were.
How long can the source clip be?
Between 5 and 30 seconds, with no single shot longer than 15 seconds. Cut longer takes into pieces first. The finished recast runs exactly as long as the input.
How many people can I swap, and in what 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 that guess 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 follows the length of the clip.
When is this the wrong tool?
Not for new action, new camera work or a different location — the source dictates 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.
