Minimax H3 Video To Video Turns Old Takes Into New Casting
Rather than rebuilding a scene from scratch, Minimax H3 Video To Video keeps the take you already approved and swaps only the people inside it — saving shoot days, not just render time.
- A casting pass, not a fresh generationBecause the clip already exists, its look is never re-invented from a text prompt. The model works on top of real footage and edits who appears in it.
- Up to four newcomers, one photo eachSupply a clear portrait per performer and they inherit the leading roles, reading left to right across every shot those roles turn up in. A short prompt can reassign the pairing.
- The take keeps its acting and its soundGesture, rhythm, lighting, lens movement, cutting pace and the existing audio track all carry through, so the output drops back into the timeline as it is.
Running Minimax H3 Video To Video: Three Steps
Start with a take that already works, match your reference photos to the people on screen, then render the swap — preview first, master second.
What Minimax H3 Video To Video Does Best
Acting, edit points and the entire soundtrack are inherited from your source clip; only the faces — and, when the photo shows them, hair and wardrobe — are new.
Four performers, mapped left to right
Four photos is the ceiling, and they take the leading roles in the order they appear on screen, holding identity across cuts. A short prompt can reshuffle that assignment.
The performance belongs to your footage
Expression, gesture, timing, light and lens motion all come from the source, while the new faces and clothing are drawn from the portraits you upload.
Edits and audio pass straight through
Your cutting rhythm and existing track survive the swap, so the result slots into a locked edit instead of needing to be rebuilt from zero.
Cheap previews, clean masters
Run a 768p pass to verify the swap before paying for 1080p, and because runtime mirrors the source, cost tracks clip length rather than guesswork.
Hair and wardrobe follow the photo
A reference that shows more than a face brings hair and clothing along too, which is why a half-body frame 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 whenever the footage is perfect but the performer is not.
Answers to Common Minimax H3 Video To Video Questions
What the tool changes, what it protects, and where it stops working — quick answers before you upload a clip.
What exactly happens when I run a recast?
The performers in your footage are replaced by the people in the photos you upload. Motion, camera work, cuts and audio remain as they were, and by default the photos claim the leading roles left to right in every shot those roles appear in.
How long can the source clip be?
Between 5 and 30 seconds, with no single shot longer than 15 seconds — split longer takes before uploading. The recast returns at the same length as the input.
How many performers can I swap, and in what order?
Up to four, one photo each. By default they claim the leading on-screen roles left to right; a prompt like 'the woman on the right becomes person 1' can change that mapping.
Which photos give the cleanest results?
One sharp, front-facing, evenly lit portrait per person. A half-body frame carries hair and clothing better than a tight headshot. Skip sunglasses, hats, hands over the face, group shots and heavily filtered or low-resolution images.
Should I preview at 768p or go straight to 1080p?
Always preview at 768p to confirm the swap reads correctly, then commit to the 1080p master. Cost scales with clip length more than with resolution alone.
When is this the wrong tool?
Choose something else when you need new motion, new camera moves or a different location. Results also weaken with busy crowds, small or distant faces, fast action, occlusion after hard cuts, and identity can drift back toward the original performer in long shots or profile turns.
Recast Your Next Clip with Minimax H3 Video To Video
Give the roles in an existing cut to different performers while timing, camera movement, edit points and sound stay exactly as shot. Then read the Recast guide or compare the related MiniMax, Hailuo and Kling models.
