MiniMax face swap: a cast change on a locked cut
It is not a video generator. It swaps the people in footage you have already finished, so every gesture, camera move, edit and audio line survives untouched.
- A recast, not a regenerationThe motion and edit are never rebuilt. MiniMax face swap re-casts your existing footage, so the result drops straight back into the original timeline.
- Left-to-right face matching, with prompt overrideEach new person gets one portrait, assigned left to right and kept consistent across cuts. A short prompt can change which photo maps to which role.
- The source clip supplies the performanceHead turns, gestures, lighting and camera drift all come from the original take. Only the faces and clothing are taken from your reference images.
How MiniMax face swap changes the cast
Three steps take a finished clip to a new cast while keeping its duration and audio exactly as they were.
What MiniMax face swap handles well
Designed for footage that is already cut correctly except for the actors. The motion, edit rhythm and audio remain, and only the faces are replaced.
Recast up to four people, left to right
You can supply up to four portraits, one per role, and each photo takes over a main character in every shot they appear in. A prompt can change the order.
The acting stays, the cast changes
Gestures still land on the same beat, lighting falls the same way, and the camera moves as before. Only the faces and outfits are new.
Edit points and audio are preserved
The cutting pattern and sound mix are inherited from the source, so the recast can drop into a locked edit without re-timing or re-recording.
768p preview, 1080p final render
Check whether the likeness holds at 768p, then render at 1080p. The output length matches the source, so cost scales with duration.
What makes a good reference portrait
A sharp, evenly lit, front-facing photo works best. A half-body shot captures hair and clothing better than a tight headshot. Avoid sunglasses, hats and group photos.
Where the recast holds and where it fails
Avoid crowds, distant faces, fast action and occlusion after hard cuts. In long shots or profile turns, the likeness may drift back toward the original actor.
MiniMax face swap: frequently asked questions
Answers about source clip limits, how portraits are assigned, what makes a good reference photo, and where the recast works best.
What exactly does MiniMax face swap do?
It inserts the people from your portraits into existing footage while preserving the original motion, camera work, cuts and audio. Think of it as a cast change on a locked edit.
What is the maximum source video length?
The clip must be between 5 and 30 seconds, and no single shot can exceed 15 seconds. Split longer footage first; the result returns at the same length.
How many faces can I swap, and in what order?
Up to four, with one portrait per person. By default, photos fill the main roles from left to right. A prompt such as 'the woman on the right becomes person 1' reverses that mapping.
Which reference photos produce the best result?
Choose sharp, evenly lit, front-facing portraits. A half-body frame is better for hair and clothing. Avoid sunglasses, hats, hands covering the face, group shots and heavy filters.
Should I preview at 768p or go straight to 1080p?
Run a quick 768p preview to confirm the casting looks right, then render the final at 1080p. Pricing is based on clip duration.
When is MiniMax face swap not the right tool?
Avoid it when you need new motion, different camera moves or a new location, because the source clip controls those. Crowds, distant faces and fast action after hard cuts are also weak spots.
