Why Creators Reach for Minimax H3 Video To Video
Treat it as a recast rather than a regeneration: every element your footage already nails is preserved, and only the on-screen performers are replaced.
- Not a generator — a cast replacementInstead of building a scene from nothing, the tool works on footage you already own, so the original look, lighting and framing are never re-created.
- Up to four performers from four photosSupply one clear portrait per newcomer — four at most — and they inherit the leading roles, claimed from left to right wherever those characters appear.
- Your original take carries the actingGestures, timing, lighting, lens movement, edit rhythm and the existing audio all come from your file, so the finished swap drops straight into the locked cut.
How Minimax H3 Video To Video Works in Three Steps
Pick a take you are already happy with, order your reference photos, then let the swap render — the whole job takes three short passes.
Capabilities That Keep Your Edit Intact
The performance, the edit and the soundtrack all stay yours; the tool only decides which faces appear inside them.
Four faces, mapped left to right
Four photos is the limit, and each one claims a leading role in left-to-right order, holding that identity across cuts. A brief prompt can reshuffle the assignment.
Same performance, different faces
Gestures, rhythm, expressions, lighting and camera movement are inherited from your footage, while the new faces and clothing come from the photos you supply.
Editing rhythm and audio survive
Your cutting pace and the original soundtrack come through unchanged, so the output drops into a locked edit with no rework required.
Cheap preview, high-resolution master
Validate the swap with a 768p pass before paying for the higher resolution, and since runtime follows your input, cost tracks clip length.
Hair and wardrobe travel with the photo
When your reference shows more than a face, hair and clothing come along too — which is why a half-body shot outperforms a tight headshot.
Made for takes that are already right
Film crews, brand marketers, social creators and fashion or commerce teams reach for it when the scene is perfect but the performer is not.
Minimax H3 Video To Video: Frequently Asked Questions
Answers to the questions people ask before recasting a clip they have already finished.
What exactly does this tool do?
Upload a short clip plus a portrait for each new performer, and the tool re-casts the leading roles in that footage. Everything else — motion, framing, edits, sound — is inherited from your file instead of being generated again.
Is there a length limit on my clip?
Input runs 5 to 30 seconds, and no single shot should go past 15 seconds, so split longer sequences first. The recast you get back matches the length of what you fed in.
How many performers can I replace at once?
Four is the maximum, one photo each. By default they claim leading roles from left to right, though a prompt such as 'the woman on the right becomes person 1' can remap who becomes whom.
Which photos give the best results?
Sharp, front-facing, evenly lit portraits, one per person. A half-body frame carries hair and clothing better than a tight headshot. Skip sunglasses, hats, hands covering the face, group shots, and low-resolution or heavily filtered images.
Do I need 1080p, or is 768p enough?
Start at 768p to confirm the swap looks right, then lock in the 1080p master. Cost follows how long the clip runs rather than resolution alone.
When is this the wrong tool?
Not when you need fresh motion, new camera moves or a different location. Accuracy also drops with dense crowds, small or distant faces, fast action, or occlusion after hard cuts, and identity can drift back toward the original performer in long shots or profile turns.
