What MiniMax Swap Changes — and What It Leaves Alone
Think of it as casting, not generating. Everything the take already nails — blocking, lighting, pacing, sound — carries through untouched; the performers are the only thing that changes.
- Casting, Not RegenerationThe cut you signed off on stays exactly as it is. Photos step in for the on-screen performers, so no other part of the clip has to be rebuilt.
- Four New Faces, Ordered Left to RightHand over up to four portraits, one per person. They take the lead roles in the order they appear on screen, and a short written prompt lets you reassign any of them.
- Acting and Audio Come Along UntouchedGestures, glances, lighting and camera work are all inherited from the source clip, while faces and wardrobe arrive from your images. Edit points and the soundtrack never move.
How MiniMax Swap Works, Step by Step
Go from an approved take to a recast cast in three moves — nothing gets reshot or rebuilt.
What MiniMax Swap Brings to the Edit
A clear look at what survives the swap, what it alters, and where it stops.
Faces Followed Through Every Cut
Each new face is tracked across edit points rather than re-applied shot by shot, so identity stays consistent as the sequence jumps.
Wardrobe Usually Travels With the Photo
Hair and garments tend to come across with the portrait, even from a tight headshot. Want only the face changed? Say so in the prompt and the original wardrobe stays.
Fits Straight Into an Existing Timeline
Rhythm and sound come out the other side untouched, so the finished recast can go back into the timeline it came from — no re-editing required.
Cheap Preview Before the Full-Resolution Render
Judge the new cast at 768p first, then pay for 1080p once it looks right. Runtime is inherited from the source, so pricing follows clip length.
What Makes a Good Reference Portrait
Shoot sharp, head-on and evenly lit, one portrait per performer. Skip sunglasses, hats, hidden faces, group pictures and heavily filtered or low-resolution files.
Where the Tool Reaches Its Limits
Movement, staging and location are inherited, so reach for something else if those must change. Crowded frames, distant faces, fast action, occlusion after a cut and drift back toward the original performer in wide or profile angles are all weak spots.
MiniMax Swap Questions, Answered
Straight answers on recasting a finished clip, photo requirements, pricing and where the tool stops.
What exactly does the MiniMax H3 recast model do?
It swaps the performers in a clip you already own for the people in your photos, while motion, camera work, edit points and audio stay as they were.
What length of source video is accepted?
Anywhere from 5 to 30 seconds, and no single shot beyond 15. Split longer takes first — the result always matches your input's runtime.
How many performers can be swapped at once?
Up to four, with one portrait each. They fill the lead roles left to right by default, so line your photos up with the screen; a prompt can override the order.
Which reference photos give the cleanest result?
Sharp, straight-on portraits with even lighting, one per person. Hair and clothing usually follow the image — prompt a face-only swap to keep the wardrobe from the clip.
Is 768p or 1080p the better choice?
Run 768p first to check that the identities hold, then commit to 1080p for the final. Cost follows runtime, so clip length drives the price.
When is this the wrong tool for the job?
Whenever the motion, camera or location has to change. Crowds, small faces, fast action, occlusion after a cut and drift back to the original performer also cause trouble.
