Recasting Without Re-Editing: What This Tool Does
The tool works on a clip that is already locked. Your footage supplies the performance, the camera work and the sound; the portraits you upload supply the new faces.
- A cast change, not a fresh renderEverything the clip already gets right — blocking, framing, cut rhythm, sound — is left alone. Only who appears on screen is switched.
- Up to four portraits, matched left to rightEach photo lines up with one performer, starting from the leftmost face in frame by default. A short written instruction reorders the pairs whenever that default misses.
- The source footage does the actingEye lines, head turns, timing, expressions, set lighting and lens character all come from the original clip; faces and wardrobe come from your uploads, and the same person is followed across scene changes.
Running MiniMax H3 Max Recast in Three Steps
Upload a locked clip, attach one portrait per performer, check the casting in a 768p pass, then finish the delivery at 1080p.
What MiniMax H3 Max Recast Brings to an Edit
Built to protect a finished cut rather than start from scratch: motion, cut points and sound survive, only the performers change, and a 768p preview comes before the 1080p render.
Four-person casting with left-to-right order
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' rewires the pairing.
Motion and expressions carry over
Eye direction, head turns, comic timing, facial expression, set lighting and lens behaviour all stay from the original take; only faces and wardrobe are pulled from your photos.
Cuts and soundtrack are preserved
The edit pattern and the existing audio remain intact, so the output drops straight into a finished timeline without a re-edit or a re-record.
Face-only mode when styling has to hold
Left unprompted, 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 — verified in our 23 October 2026 test.
Cheap preview, final render at 1080p
A quick 768p pass reveals whether the casting reads correctly before you commit to 1080p. Runtime mirrors the source, so cost scales with how long the clip is.
Tried on very different footage
Sample recasts cover a music-video close-up, a barista commercial, a fencing bout, a skate launch and a fish market at dawn — each keeping its own motion, cuts and sound.
MiniMax H3 Max Recast — Questions Answered
Straight answers on how MiniMax H3 Max Recast handles footage, portraits, length limits and render settings.
What separates a recast from a normal video generation?
Generation invents footage. This tool edits footage you already have: the people on screen are replaced by the people in your photos, while movement, camera work, cut points and audio remain from the original.
What length of source video is supported?
Between 5 and 30 seconds, and no single shot longer than 15 seconds. Split longer takes into pieces first. The finished recast runs exactly as long as the input.
How many performers can be swapped, and in what order?
Up to four, with one photo each. By default the portraits replace the leading performers from left to right across the frame; a prompt can reassign the pairs if that order is wrong.
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 original hair and wardrobe must stay, ask for a face-only swap.
Is 768p or 1080p the right choice?
Use 768p to confirm the casting reads correctly, then render at 1080p for delivery. Pricing follows the length of the clip.
When does this tool not fit?
When you need new action, new camera work or a different location — the source decides those. Results weaken with crowded scenes, 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.
