Minimax H3 Recast: Rework the Cast, Not the Cut
Instead of generating a new video, Minimax H3 Recast re-dresses one you already own — timing, framing and soundtrack are left alone while the performers are replaced.
- Casting changes on a locked editFeed the tool an existing clip plus a set of portraits, and it re-casts the scene in place rather than rendering something new from scratch.
- Each face stays tied to its roleMatch your uploads to the order the performers appear, and the pairing survives every cut — no drifting identity from one shot to the next.
- The performance is never re-generatedGlances, pauses, expressions, set lighting and camera movement all remain from the original shoot; only the likeness and wardrobe arrive from your photos.
How Minimax H3 Recast Works, Step by Step
From a finished clip to a fresh lineup of performers in three short steps.
What You Get with Minimax H3 Recast
A recast that respects the work you already did — performance, edit, sound and composition all survive the swap.
Four roles per pass
You can bring four new faces into a single clip; each keeps the role you assign and stays consistent across the shots that person appears in.
Text prompt to remap roles
When screen order is not the casting you want, a short written instruction tells the tool which photo maps to which performer.
Bodies and beats stay untouched
No part of the performance is invented — movement, timing, expressions, lighting and lens work are inherited from the source, with only likeness and clothing replaced.
Edit and soundtrack intact
Your cutting rhythm and the audio bed come through unchanged, so the result reads as the same film with different leads.
Low-cost draft, full-res finish
A 768p trial run costs little and shows whether the faces land, before you commit to the 1080p render; credits scale with clip length.
Wardrobe and hair come from the photo
Framing more than the head in your reference lets hairstyle and clothing carry across too; a half-body shot transfers them far better than a tight crop.
Minimax H3 Recast: Common Questions
Short answers on cast swaps, source clips, photo requirements and output quality.
What exactly does Minimax H3 Recast change?
It is a replacement tool rather than a generator. The portraits you supply take the place of the people in your footage; motion, framing, edits and audio are inherited from the source file.
Is there a length limit on the source clip?
Yes — keep the file between 5 and 30 seconds and split any single shot longer than 15 seconds. The output matches the runtime you upload.
How many performers can I swap at once?
Up to four, each with its own photo. Roles are assigned in screen order by default, so arrange uploads to match; a prompt can reassign them.
Which portraits give the best results?
One sharp, evenly lit, front-facing shot per person. Half-body framing carries hair and clothing better than a tight crop; skip sunglasses, hats, covered faces, group photos and anything blurry or heavily filtered.
Do I need to render at full resolution first?
Start with the 768p pass to confirm the match, then render the 1080p file for delivery. Credits follow clip length, so the trial is the cheap way to catch a mismatch.
When is this tool the wrong choice?
When the scene itself must change — new movement, new camera work, a new location — since those come from the source. Results also weaken on crowded frames, distant or small faces, fast action and faces hidden after a hard cut, and likeness can drift back toward the original performer on long takes or in profile.
