Minimax H3 Video To Video — Recasting, Explained
This is not another text-to-video engine. It takes footage that already works and re-casts the people inside it, leaving the performance and the edit exactly where they are.
- A recasting pass, not a fresh generationIt works on material you have already captured, so the original look is never rebuilt from scratch — only the on-screen identities are replaced.
- Up to four faces, one photo eachSupply a single clear portrait per new performer and they inherit the leading roles on screen, matched left to right in every shot where those roles appear.
- Your footage keeps the performanceGesture, timing, lighting, lens movement, editing rhythm and the original audio all come through untouched, so the output drops straight into your finished timeline.
Three Steps with Minimax H3 Video To Video
Start from footage you are happy with, order your portraits, then render the swap — quick preview first, full master second.
Where the Recast Engine Excels
Recasting that carries over the performance, the edit and the soundtrack, so the only thing that changes is who appears on camera.
Four faces, matched left to right
You can hand over up to four identities at once, and they claim the leading roles left to right in every shot those roles appear in. Faces are followed across cuts, and a short prompt can change the order.
Same performance, new faces
Everything that makes the take work — gesture, pacing, expression, lighting, camera motion — comes from your footage, while the new look and wardrobe come from the photos you supply.
Edits and audio ride along
Your cutting rhythm and the existing soundtrack survive the process, so the result can go straight into a locked sequence instead of being rebuilt.
768p to check, 1080p to deliver
Run a 768p pass to verify the swap before paying for higher resolution, and since runtime mirrors your input, cost follows the clip's length.
Hair and clothing come from the photo
When your reference shows more than a face, hairstyle and garments transfer too — which is why a half-body frame outperforms a tight headshot.
Made for footage that already works
Film crews, brand teams, social creators and commerce studios reach for it when a take is perfect but the wrong performer is standing in it.
Minimax H3 Video To Video — Common Questions
What people ask before swapping the performers in a clip that is already finished.
What exactly does this tool do?
It replaces the performers in a video you already own with the people from your uploaded photos. Motion, camera work, edits and audio are preserved, and the photos take over the leading roles from left to right in every shot where those roles appear.
What length of video can I upload?
Between 5 and 30 seconds, with no single shot longer than 15 seconds — split longer takes first. The recast returns at the same length as your input.
How many performers can be swapped, and in which order?
Up to four, one photo each, and by default they claim the leading on-screen roles left to right. A prompt such as 'the woman on the right becomes person 1' can change that mapping.
Which reference photos give the best results?
One sharp, front-facing, evenly lit shot per person. A half-body frame carries hair and clothing better than a tight headshot. Skip sunglasses, hats, hands over the face, group photos, and low-resolution or heavily filtered portraits.
Is 768p or 1080p the right choice?
Use 768p to confirm the swap reads correctly, then commit to the 1080p master. Cost scales with clip length rather than resolution alone.
Are there cases where this tool is the wrong fit?
Yes — it cannot invent new motion, new camera moves or a different location. Results also weaken 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.
