What MiniMax Swap Brings to a Finished Edit
Think of it as a casting change, not a regeneration: what your clip already gets right stays as shot, while on-screen performers are replaced by people from your photos.
- A Casting Change, Not a Fresh GenerationThe take you already approved remains untouched; photos of new performers simply take over on screen, so no other part of the footage has to be redone.
- As Many as Four Faces, Ordered Left to RightSupply one photo per performer, up to four. They take over the main people in left-to-right screen order by default, and a brief prompt can reassign the mapping.
- Acting and Audio Stay With the OriginalGestures, glances, lighting and camera moves come from the source take; faces and outfits are drawn from your photos, while edit points and soundtrack stay as they were.
How MiniMax Swap Works in Three Steps
Go from an edited clip to a recast version in three moves — no new shoot and no timeline rebuild required.
What MiniMax Swap Can Do
See what stays the same, what gets replaced, and where the tool works best.
Faces Followed Through Every Cut
Your photos replace the main performers in screen order, and each face is tracked across every edit point rather than reset at each new shot.
Hair and Clothing Come From the Photo
Hair and outfits tend to come along with the reference photo, even from a close headshot. Add a prompt if you want only the face changed and the original wardrobe kept.
Fits Into an Already-Edited Timeline
The edit rhythm and soundtrack pass through the swap untouched, so the result can drop into a completed timeline instead of forcing a restart.
Test at 768p Before Paying for 1080p
Check the casting at 768p before committing to the higher resolution. Runtime carries over from the source, so pricing scales with clip length.
Photo Tips for a Cleaner Swap
Use a sharp, straight-on portrait with even lighting for each person. Avoid sunglasses, hats, covered faces, group photos, heavy filters, and low-resolution images.
Known Limits: Motion, Crowds and Wide Shots
Camera movement, blocking and setting come from the input, so this is not the right choice when those need to change. Crowded frames, tiny or distant faces, fast action, post-cut occlusion, and identity drift in wide or profile shots are weak spots.
MiniMax Swap: Common Questions
Answers to frequent questions about replacing performers in existing footage with MiniMax Swap.
What exactly does MiniMax H3 Recast do?
It swaps the on-screen performers in your existing footage for the people in your photos, while the original movement, camera work, edits and sound remain unchanged.
What length should my source video be?
Your clip should be 5 to 30 seconds long, and no single shot should exceed 15 seconds. Split longer takes first; the output keeps the same length as the input.
How many faces can I replace, and in what order?
You can replace up to four people, using one photo each. They map from left to right by default, so match their screen positions; a prompt can change who becomes person 1.
Which reference photos work best?
Use a sharp, straight-on portrait with even lighting for each person. Hair and clothing often follow the photo, so prompt a face-only swap if you want to keep the original wardrobe.
Should I preview at 768p or render at 1080p?
Start at 768p to confirm the casting looks right, then finish at 1080p. Cost follows clip length, so runtime determines the price.
When is MiniMax Swap not the right choice?
Avoid it when you need new movement, camera angles or a different setting. Crowded scenes, small faces, fast action, post-cut occlusion and identity drift can also cause problems.
