Recast Finished Footage Without Re-Shooting
Minimax H3 Video To Video is built for takes that already work — it hands the on-screen roles to your own performers while every other detail of the shot stays exactly as it was.
- Casting swap, not a fresh generationNothing in the scene is regenerated from scratch — the clip you already shot stays the blueprint, and only the people appearing in it are exchanged.
- Up to four new faces, cast from photosSupply one clear portrait per performer and each one claims a leading on-screen role, assigned left to right wherever that role shows up in the edit.
- Your footage keeps the performancePacing, gestures, lighting, lens motion, edit rhythm and the existing soundtrack all survive the swap, so the recast drops straight into the finished cut.
How Minimax H3 Video To Video Works in 3 Steps
Start with footage you are already happy with, line up your portraits, then let the model hand the roles over to your new cast.
Built for Swapping Casts, Not Scenes
Every recast preserves the performance, the edit and the audio of your original clip — only the people on screen come out different.
Four performers, assigned left to right
Four portraits is the maximum, and each one claims a leading on-screen role from left to right, tracked through cuts. A brief prompt can reorder that mapping.
Same acting, brand-new faces
Gestures, timing, expressions, lighting and camera motion are inherited from your footage, while the new faces and wardrobe come from the photos you supply.
Your edit and soundtrack survive
The rhythm of your cut and the existing audio pass through unchanged, so the finished recast slots into a locked timeline with no rebuilding required.
Check in 768p, finish in 1080p
Run a low-cost 768p pass to confirm the swap, then commit to the 1080p master. Because output length mirrors your input, cost follows clip duration.
Hair and clothing come from your photo
When the reference shows more than a face, hair and garments transfer as well — 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 whenever a take is perfect but the wrong performer is standing in it.
Minimax H3 Video To Video: Questions Answered
Everything worth knowing before you hand a finished video over to a new cast.
What exactly does this tool do?
It replaces the performers in a video you already have with the people in your uploaded photos. Source motion, camera work, cuts and audio stay as they were, and by default your photos take the leading roles left to right in every shot those roles appear in.
How long can the source video be?
Between 5 and 30 seconds, and no single shot may run past 15 seconds, so split longer takes beforehand. The recast comes back at the same length as your input.
How many people can I swap, and in which order?
As many as four, one photo each, and they claim 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 sharp, front-facing, evenly lit photo per person. A half-body shot carries hair and clothing better than a tight headshot. Avoid sunglasses, hats, covered faces, group photos, and low-resolution or heavily filtered portraits.
Should I preview in 768p or go straight to 1080p?
Preview at 768p to confirm the swap reads correctly, then commit to the 1080p master. Cost scales mainly with how long the clip runs rather than with resolution alone.
When is this the wrong tool?
Skip it when you need new motion, new camera moves or a different environment. Accuracy also weakens with busy 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.
