Give Finished Footage a New Cast with Minimax H3 Video To Video
Think of it as a casting change made after the shoot — every choice your clip already made stays exactly where it is, and only the faces in front of the lens get replaced.
- Not a generator — a recast layerNothing here is built from scratch; the tool works on top of footage that already exists, so the original look, grade and rhythm are never re-created.
- Up to four newcomers, cast from photosSupply a single clear portrait per new performer — four is the maximum — and they inherit the principal on-screen roles, matched left to right, in every shot those roles appear in.
- Your footage supplies the performanceGestures, delivery, lighting, lens motion, cutting rhythm and the existing soundtrack all carry through, which means the output drops straight into your locked edit.
Running Minimax H3 Video To Video in Three Steps
Pick a clip you already like, order your reference portraits, then let the swap render — that is the entire workflow.
Where Minimax H3 Video To Video Excels
Everything your source clip got right — performance, pacing, sound — is retained, and only the people appearing in it are exchanged.
Four performers, mapped left to right
You can supply no more than four portraits, and they step into the principal roles in left-to-right order across every shot. The tool tracks each identity through cuts, and a short prompt can change the assignment.
Same acting, different faces
The performance originates in your clip — every gesture, expression, pause and camera move is kept — while the faces and wardrobe are drawn from the images you provide.
Editing and audio left alone
Your cut's rhythm and its soundtrack come through unchanged, letting the output drop into a locked timeline without any rework.
Cheap test pass, clean final master
Run a 768p check first so you only pay for the higher resolution once the faces look right, and since output length matches input, cost follows the clip's duration.
Hair and wardrobe come from your photo
If your reference captures more than the face, hairstyle and garments transfer as well — which makes a half-body frame a better choice than a close-cropped portrait.
Made for takes that are already right
Production crews, brand teams, social creators and fashion or retail marketers reach for it whenever a shot is flawless but the wrong person is standing in it.
Minimax H3 Video To Video — Questions Answered
Straight answers on recasting completed footage, photo requirements, clip length limits, and when this tool is simply the wrong fit.
What exactly does this tool do?
It replaces the people appearing in an existing video with the individuals from your uploaded images. The source's motion, camera movement, cutting and sound are left alone, and unless you say otherwise the photos claim the principal roles in left-to-right order wherever those roles occur.
What length of source video is accepted?
Between 5 and 30 seconds, with no single shot running longer than 15 seconds — so cut longer material into pieces first. Output duration matches input duration exactly.
How many people can I swap, and how are they ordered?
Up to four, one image apiece. By default they fill the main roles in left-to-right sequence, and a short prompt can remap that assignment if the default does not suit your scene.
Which photos give the best results?
Use one crisp, well-lit, front-facing image per person. A half-body frame transfers hair and garments more reliably than a tight headshot. Stay away from sunglasses, hats, obscured faces, group shots and blurry or heavily filtered pictures.
Is 768p or 1080p the better choice?
Check the swap at 768p first, then move to the 1080p master once you are satisfied. Cost is driven mainly by clip duration, not by resolution on its own.
When is this the wrong tool?
Look elsewhere if you need fresh movement, different camera work or a new setting. Accuracy also drops in crowded frames, with tiny or distant faces, during fast action, after abrupt cuts, and identity may slide back toward the original performer in long shots or when someone turns to profile.
