Minimax H3 Recast
Minimax H3 Recast swaps the people in a finished clip for the faces in your reference photos while the original timing, camera moves, cuts and soundtrack stay untouched. Cast up to four actors, test at 768p, then render the final at 1080p.
What Is Minimax H3 Recast?
Minimax H3 Recast is an AI recast tool that replaces the people inside an existing video with the people from your reference photos. It is a casting swap, not a generator: everything the footage already does well — head turns, timing, expressions, lighting, lens movement, edit rhythm and the original soundtrack — carries over untouched, and only who is on screen changes. Load a clip between 5 and 30 seconds long, add one clear photo per new person up to four, and Minimax H3 Recast lines them up against the main people from left to right in every shot they appear in, tracking identity across the cuts. A short text prompt overrides that order when a scene is unusual — telling it that the woman on the right becomes person one, for instance. Test the casting in a quick 768p pass, then commit to a 1080p render once the faces hold; output length always matches the source, so cost follows clip duration. It runs entirely in the browser, and it suits directors replacing stand-ins, advertisers recasting one spot for several markets, short-form creators reusing a skit, fashion teams reworking lookbooks and e-commerce teams localising product demos.
- A Casting Swap, Not a New GenerationMinimax H3 Recast holds on to everything the source footage already does well and changes only who is in it. Motion, camera work, cuts and audio are inherited rather than rebuilt, so the result still reads as the performance that was actually filmed.
- Up to Four People, Ordered Left to RightSupply one photo per new person, up to four, and the main people are replaced from left to right in every shot they appear in, with identity tracked across cuts. A short prompt overrides the mapping whenever the scene needs it.
- Test at 768p, Finish at 1080pCheck casting and identity on a short 768p pass before paying for the higher resolution. Minimax H3 Recast keeps the length of the source clip, so the final render costs what the duration costs rather than what the cast size costs.
How to Use Minimax H3 Recast
Minimax H3 Recast takes three steps: load the source clip, line up your reference photos, then test and render. There is nothing to install and no timeline to learn — the performance stays exactly as filmed while the tool changes who is in it.
Why Teams Reach for Minimax H3 Recast
When the take is right and only the casting is wrong, reshooting is the expensive answer. Minimax H3 Recast turns that problem into a drop-in replacement: the clip keeps its own length, rhythm and soundtrack, and the people inside it change to match your photos. Because it works on finished footage instead of generating from scratch, the result still reads as the original performance — same beats, same lens, same sound — which makes it usable for delivery rather than only for tests.
Recast Without a Reshoot
Faces are replaced on footage that is already shot, so a finished clip keeps its performance, its edit and its audio. Nothing has to be re-blocked, relit or re-recorded to change the cast.
One Ad, Many Markets
Advertisers produce a spot once and then run it through Minimax H3 Recast for each market or audience, swapping in up to four new people per version while the script, the timing and the soundtrack stay identical.
Performances That Already Work
Short-form creators keep a dance, a gag or a reaction that already lands and put new characters into it with Minimax H3 Recast, instead of asking the same people to repeat the take.
Lookbooks and Product Demos
A single runway walk or turntable shot can be recast across several models, and a product demo can be re-presented for each regional storefront, with Minimax H3 Recast carrying hair, outfit and motion from the reference photo.
768p and 1080p, Priced by Duration
Minimax H3 Recast offers a 768p test pass and a 1080p final render. Output length equals the source, so the cost of a recast tracks how long the clip is rather than how large the cast is.

Minimax H3 Recast — Frequently Asked Questions
Answers on what Minimax H3 Recast does, how long the source clip may be, how many people can be recast and in what order, which reference photos give the best result, when to render at 768p or 1080p, and the cases it is not built for.
What does Minimax H3 Recast actually do?
Minimax H3 Recast replaces the people in an existing video with the people from your reference photos. Motion, camera work, cuts and audio are kept, so it is a casting swap on finished footage rather than a new generation. By default the photos replace the main people from left to right in every shot they appear in.
How long can my source video be?
Between 5 and 30 seconds, and no single shot may run longer than 15 seconds. Long takes are split first, and Minimax H3 Recast always returns a clip the same length as the source.
How many people can I recast, and in what order?
Up to four, one photo per person. Minimax H3 Recast replaces the main people from left to right by default, so the photos should be ordered to match screen positions. A prompt such as "the woman on the right becomes person 1" overrides that order.
Which reference photos work best?
One sharp, front-facing, evenly lit photo per person. A half-body shot carries hair and clothing better than a tight headshot, and the tool works best when sunglasses, hats, hands over the face, group photos and heavily filtered portraits are avoided.
Should I test at 768p or render at 1080p?
Do both. A short 768p pass lets Minimax H3 Recast confirm the casting and the identity before you pay for the higher resolution, then render the final cut at 1080p. Cost scales with clip duration either way.
When is Minimax H3 Recast the wrong tool?
When new motion, new camera moves or a changed environment are needed, since the source dictates all of that. Minimax H3 Recast also struggles with busy crowds, small or distant faces, and fast action or occlusion after hard cuts, and identity can drift back toward the original actor in long shots or profile turns.
Recast a Finished Clip with Minimax H3 Recast
Minimax H3 Recast drops new faces into a clip you have already shot while the original timing, camera moves, cuts and soundtrack play on untouched. Load the source, add up to four reference photos, test at 768p and render the final at 1080p — then download a recast that is a drop-in replacement for the version you had. Open the generator and let it change who is on screen without touching anything else.
