MiniMax H3 Max Recast: A New Cast for Footage You Already Cut
The clip you already edited does the acting and carries the sound; the portraits you add decide who appears on screen.
- An identity swap, not a new takeWhatever the source already gets right — movement, framing, edit points, audio — is left intact. Only who is on screen changes.
- Up to four faces, matched left to rightEach photo corresponds to one performer and, unless you say otherwise, the pairing runs across the frame from the leftmost person to the rightmost. A short prompt fixes the order when it is off.
- The source footage directs the performanceEye lines, head turns, timing, expressions, set lighting and lens character are inherited from the original; faces and wardrobe come from your uploads, and the same performer is followed across cuts.
Three Steps to a New Cast with MiniMax H3 Max Recast
Pick a clip whose performance and sound are final, upload one portrait per performer, check the identities at 768p, then render at 1080p.
Core Capabilities of MiniMax H3 Max Recast
Built for casting rather than generating: motion, cuts and sound in your source are protected, only the performers change, and a 768p preview comes before the 1080p render.
Casting for up to four people, ordered left to right
Four portraits at most 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.
Expressions and movement carry over
Gaze direction, 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 left alone
The edit pattern and the existing audio survive, so the result drops straight into a finished timeline instead of forcing a re-edit or a re-record.
Face-only mode keeps the styling
Without guidance the tool tends to borrow hair and clothing from the portrait, even a tight headshot. Asking for a face-only change preserves the original styling — something we confirmed in our 23 October 2026 run.
Low-cost preview, 1080p delivery
A quick 768p pass reveals whether the casting reads correctly before you commit to 1080p. Runtime follows the source, so cost scales with clip length.
Tried on very different footage
Test 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 and Answers
Answers on source length, portrait choice, cast ordering, preview resolution and the cases where a recast is the wrong tool.
What separates a recast from a brand-new generation?
Generation creates footage from scratch. Here the footage already exists: the people in your photos replace the on-screen performers, while movement, camera work, edit points and audio come from the original.
How long can the source video 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 performers can be replaced, and in which order?
Up to four, one photo each. Portraits take over the leading performers from left to right across the frame by default; a prompt can re-pair them when that default is wrong.
Which reference photos give the best result?
Sharp, evenly lit, straight-on portraits, one per person. Avoid sunglasses, hats, hands over the face, group shots, low-resolution or heavily filtered images. If the original hair and wardrobe must survive, request a face-only replacement.
Is 768p enough, or should I render at 1080p?
Use 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?
When you need new action, new camera work or a different location — the source dictates all of those. Results also 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 a New Cast in Your Finished Clip with MiniMax H3 Max Recast
Upload the clip whose timing and sound are already locked, add portraits of the new cast, and let the swap run — camera moves, cuts and audio stay as they were.
