Minimax H3 Recast Turns Old Footage Into New Casting
Think of it as recasting after the shoot wraps: your finished clip keeps its rhythm, its framing and its sound, while the faces in front of the lens are drawn from photos you supply.
- Casting changes after the edit locksGive the tool a clip you have already completed and a set of portraits; it puts those faces into the existing shots rather than generating new scenes from scratch.
- Every face stays with its roleMatch your uploads to the order in which the performers appear, and that pairing is maintained as the cut moves from one shot to the next.
- Your original performance drives everythingGlances, pauses, expressions, lighting and camera movement all arrive with the source file; the only elements taken from your uploads are the faces and the clothes.
How Minimax H3 Recast Works, Step by Step
Three short moves carry an edited clip to a completely fresh cast.
Minimax H3 Recast Features at a Glance
The details that make a recast practical: up to four performers, prompt-based ordering, and an edit, soundtrack and frame left untouched.
Four roles, assigned in screen order
You can introduce as many as four new faces, each mapped to a role by position, and that mapping survives every shot the character appears in.
Rewrite the mapping with a prompt
A short text instruction lets you decide which photo becomes which performer, useful when the default left-to-right assignment is not the one you want.
Same performance, different faces
The acting is never re-synthesised — timing, expressions, light and lens movement all belong to your source, while faces and clothing are taken from the photos you provided.
Your edit and soundtrack survive
Rhythm and audio are never rebuilt, which means the result looks like the same production with different talent rather than a brand-new render.
Low-cost preview, full-quality finish
Check the result with a cheap 768p run first, then commit to a 1080p render; what you pay scales with how long the clip runs.
Hair and wardrobe come with the photo
Photos that show more than the face bring the hairstyle and clothing along too; a half-body shot transfers those details far more dependably than a close crop.
Minimax H3 Recast: Frequently Asked Questions
Answers to the questions people ask before running a cast change with Minimax H3 Recast.
Is Minimax H3 Recast a video generator or something else?
It is a replacement tool rather than a generator. Your photos take the place of the performers already in the clip, while movement, framing, cutting and sound are all inherited from the source file.
What length should my source clip be?
Anywhere from 5 to 30 seconds in total, with no single shot running past 15 seconds. Longer sequences should be split before upload, because the output matches the length of the input.
How many performers can I change at once?
Up to four, and each one needs a separate photo. The tool maps them to the main roles by screen order unless you describe a different arrangement in the prompt.
Which reference photos give the best result?
One sharp, evenly lit photo per person, taken from the front. A half-body frame reproduces hair and clothing better than a tight head shot, and you should avoid hats, sunglasses, blocked faces, group pictures, heavy filters and anything blurry.
Do I need the 768p pass at all?
Yes — it is the cheap way to confirm the pairing before committing to the full-quality render. Since cost follows clip length, the preview keeps a bad match from becoming an expensive one.
When is Minimax H3 Recast the wrong choice?
Skip it whenever the footage itself has to change — new movement, a different camera angle or another location — because all of that is inherited from your source. Results also weaken with large crowds, tiny or distant faces, fast motion and objects crossing the face after a hard cut, and over long takes or when someone turns to profile the likeness can drift back toward the original performer.
