Minimax H3 Video To Video Turns One Good Take Into a New Cast
Think of it as re-casting a scene after the shoot has wrapped — every strength of the original take survives, and only the faces in front of the lens change.
- Not a generator, a re-casting passYour footage already exists, so this pass simply changes who is standing in it rather than rebuilding a scene from scratch off a text prompt.
- Up to four faces, one photo eachSupply a single clear photo per newcomer — four at most — and they step into the leading roles, matched from the left of frame to the right wherever those roles appear.
- Your footage keeps doing the actingGestures, timing, lighting, lens movement, edit rhythm and the existing soundtrack all come from the source, so the finished result drops straight into a locked cut.
Three Steps to a Minimax H3 Video To Video Recast
Pick a take worth keeping, line up photos of your new cast, then let the swap render — preview first, master second.
Where Minimax H3 Video To Video Excels
Everything that made the take work stays put — the only thing that changes is which faces the audience actually sees.
Four performers, matched left to right
Four photos is the ceiling, and they inherit the principal on-screen roles in left-to-right order wherever those roles show up. Identities hold across cuts, and a brief prompt can reshuffle the mapping.
The acting is inherited, not invented
Gestures, timing, expressions, lighting and camera motion all come from your footage, while the new faces and wardrobe are drawn from the photos you supply.
Your edit and soundtrack survive
Pacing and the existing audio track are preserved through the swap, which means the output can be dropped into a locked cut without any re-editing work.
Cheap previews, sharp finals
Verify the swap at 768p before committing to the higher resolution. Because runtime mirrors your source, cost tracks clip length rather than resolution alone.
Hair and wardrobe come from your photos
If the reference shows more than a face, hairstyle and clothing transfer as well — which is exactly why a half-body shot outperforms a tight headshot.
Made for takes that are already great
Film crews, brand marketers, social creators and fashion or commerce teams reach for it whenever the take is perfect but the wrong performer is in frame.
Minimax H3 Video To Video: Your Questions Answered
Everything worth knowing before you re-cast a clip, from length limits and photo choices to resolution and cost.
What exactly does this tool do to my video?
It replaces the performers in an existing video with the people shown in your uploaded photos. Motion, camera work, cuts and audio are left alone, and by default your photos take the leading roles from left to right in every shot those roles appear in.
Is there a limit on how long my source video can be?
Between 5 and 30 seconds, and no single shot may run past 15 seconds, so split longer takes beforehand. The recast comes back the same length as the input.
How many faces can I replace, and who goes where?
Up to four, one photo each. They claim the leading on-screen roles from left to right unless you say otherwise — a prompt such as 'the woman on the right becomes person 1' reassigns 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, hands covering the face, group shots, and low-resolution or heavily filtered portraits.
Do I need 1080p, or is 768p enough?
Run a 768p preview to confirm the swap reads correctly, 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 choice?
Skip it if you need new motion, new camera moves or a different environment. Results also weaken with crowded scenes, small or distant faces, fast action, or occlusion after hard cuts, and identity can drift toward the original performer in long shots or profile turns.
