What Sets Minimax H3 Video To Video Apart
Think of it as recasting after the shoot: everything the footage already does well is preserved, and only the people on screen are replaced.
- A casting swap, not a fresh generationNothing about the original look is rebuilt. The tool re-assigns who appears on screen inside footage that already exists, so the visual character of the take survives.
- One photo per performer, four maximumSupply a clean portrait for each new cast member and they inherit the leading roles in left-to-right order, across every shot those roles appear in.
- The take still carries the performanceGestures, delivery, lighting, lens movement, cutting rhythm and the existing audio all come from your source file, so the output drops straight into the edit.
How to Use Minimax H3 Video To Video
Three moves with MiniMax H3 Recast: start from a clip that already works, arrange your reference photos, then render the swap.
Where Minimax H3 Video To Video Excels
One thing changes and everything else stays: the acting, the edit and the sound come from your clip, and only the faces are new.
Four cast members, ordered left to right
Four is the ceiling. Each photo claims a leading role, matched left to right across shots, and identity is tracked through cuts. A brief prompt can reshuffle the order.
Performance kept, faces replaced
Gestures, timing, expressions, lighting and camera motion are inherited from the footage; the new faces and their wardrobe come from the images you upload.
Edits and audio come along
Your cutting rhythm and the original soundtrack survive untouched, so the output drops into a locked sequence instead of being rebuilt from scratch.
Cheap 768p check, 1080p delivery
Validate the swap at 768p before paying for the higher resolution, and since runtime matches your input, cost scales with clip length.
Hair and clothing travel with the photo
If the reference shows more than a head, hair and outfit transfer as well, which is why a half-body frame outperforms a tight headshot.
Made for takes that are already right
Studios, brand teams, social creators and fashion or commerce crews reach for it when a take is perfect but the performer in it is not.
Minimax H3 Video To Video — Common Questions
Straight answers to what creators ask before recasting footage that has already been shot, cut and mixed.
Which parts of my clip get replaced?
Only the performers. The people from your uploaded photos take over from the cast in the source video, while motion, camera work, cuts and audio stay as they were. By default the photos claim 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, with no single shot longer than 15 seconds, so split longer takes first. The recast comes back at the same length as the input.
How many people can I swap, and who goes where?
Up to four, one photo each. They take the leading on-screen roles left to right by default, and a prompt such as 'the woman on the right becomes person 1' can reassign that mapping.
Which reference photos give the best result?
A 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 low-resolution or heavily filtered images.
Is 768p enough, or should I go straight to 1080p?
Use 768p to confirm the swap reads correctly, then commit to the 1080p master. Cost tracks how long the clip runs more than resolution alone.
When is this the wrong tool?
When you need new motion, new camera moves or a different setting. Results also weaken with crowded frames, small or distant faces, fast action and occlusion after hard cuts, and identity can drift toward the original performer in long shots or profile turns.
