What MiniMax H3 Recast Does Differently
Think of it as a casting change for a take that is already locked: every frame keeps its motion, lighting and rhythm, and only the performers inside them are replaced.
- It re-casts, it does not regenerateThe footage you supply is never rebuilt from scratch. The model edits who appears inside it, so the visual character of the original take stays exactly where it was.
- Up to four performers, cast from photosSupply one clear portrait per newcomer, four at most. They inherit the leading on-screen roles, matched left to right, in every shot where those roles appear.
- Your footage keeps its performanceGesture, tempo, lighting, lens motion, cutting rhythm and the existing soundtrack all carry through untouched, so the result drops straight into a locked edit.
Three Steps to Recast a Clip with MiniMax H3
The workflow is short: pick a take you are already happy with, order your portrait photos, and let the model hand the roles over to new faces.
Where MiniMax H3 Recast Excels
It alters the cast and nothing else — the performance, the edit rhythm and the soundtrack of your source clip all come out the other side intact.
Four faces, mapped left to right
Four photos is the ceiling, and they claim the leading roles left to right wherever those characters appear. Identity holds across cuts, and a brief prompt can reshuffle the order.
Same performance, different people
Motion comes from your footage — gestures, tempo, expressions, light and camera movement survive — while faces and wardrobe are drawn from the photos you upload.
Editing and audio left alone
Your cutting rhythm and the original audio bed come through unchanged, so the output slots into a locked timeline instead of having to be assembled again.
Draft at 768p, deliver at 1080p
Check the swap in a low-cost 768p pass before committing to full resolution, and because runtime mirrors the input, spend tracks the length of the clip.
Hair and clothing come from your photo
When the reference frame shows more than a face, hairstyle and garments transfer too — which is why a half-body shot outperforms a tight headshot.
Made for footage that already works
Film crews, brand marketers, social creators and fashion or commerce teams reach for it whenever a take is flawless but the wrong performer is standing in frame.
MiniMax H3 Recast: Your Questions Answered
Straight answers on replacing the performers in footage you have already shot.
What exactly does MiniMax H3 Recast do?
It hands the on-screen roles in your existing video to the people shown in your uploaded photos. Motion, camera work, edits and audio are left alone, and by default the photos inherit the leading roles from left to right wherever those characters appear.
What length of source video is supported?
Between 5 and 30 seconds, with no individual shot running longer than 15 seconds, so split longer takes first. The recast comes back at the same duration as your input.
How many performers can I swap, and in which order?
Up to four, one photo each, and they take the leading on-screen roles left to right by default. A prompt such as 'the woman on the right becomes person 1' can reassign that mapping.
Which reference photos give the best results?
One crisp, front-facing, evenly lit image per person. A half-body frame carries hair and clothing better than a tight headshot. Steer clear of sunglasses, hats, hands covering the face, group shots, and low-resolution or heavily filtered portraits.
Is 768p or 1080p the right choice?
Run a 768p pass first to confirm the swap looks correct, then commit to the 1080p master. Cost scales with how long the clip runs rather than with resolution alone.
Are there cases where this tool is the wrong fit?
Yes — whenever you need brand-new motion, fresh camera moves or a different setting. Results also weaken with crowded scenes, small or distant faces, fast action or occlusion after hard cuts, and identity may drift back toward the original performer in long shots or profile turns.
