A New Cast for Footage You Already Shot
Think of it as recasting without a reshoot: the tool keeps the performance, pacing and sound your footage already has, and simply places different performers into the frame.
- Casting, not generationNothing is rebuilt from scratch. Your existing footage remains the source of truth, so the look, grain and grade you already approved stay exactly where they are.
- Up to four new faces per clipSupply one clean portrait for each newcomer — as many as four — and they inherit the lead roles in the order those roles appear on screen.
- The original performance is the blueprintGestures, timing, lighting, lens movement, edit rhythm and the existing audio track all come through untouched, so the result drops straight into your timeline.
How to Use Minimax H3 Video To Video
Start with footage you are already happy with, match a photo to each role, then render. No timeline surgery, no reshoot and no re-recording.
Where MiniMax H3 Recast Excels
Only the faces change. The performance, the rhythm of the edit and the original audio all survive the process intact.
Four performers, one clear order
Four portraits is the ceiling, and each one claims a lead role following left-to-right screen order across shots. A one-line prompt can reshuffle that mapping whenever you need it.
Acting comes from your footage
Body language, timing, expressions, lighting and camera motion are read from the source, while facial identity, hair and wardrobe come from the photos you provide.
Edit rhythm and audio survive
Every cut, transition and audio beat is preserved, so the finished swap drops into a locked cut instead of sending you back to the edit bay.
Cheap preview, clean master
Validate the swap at 768p before committing to 1080p, and because runtime mirrors your input, cost scales with clip length rather than resolution alone.
Wardrobe and hair come along too
A reference that shows more than a face carries clothing and hair across as well — which is why a half-body frame beats a tight headshot.
Made for takes you refuse to reshoot
Film crews, brand marketers, social creators and fashion or commerce teams reach for it whenever a shot is perfect but the performer in it is not the one they need.
MiniMax H3 Recast: Questions Answered
Straight answers on giving an existing clip a new cast, from photo requirements and clip limits to resolution choices.
What exactly does this tool change in my video?
It replaces the people visible in footage you already have with the people from your uploaded photos. Motion, framing, cuts and audio are left as they were, and each photo claims a lead role following left-to-right screen order unless a prompt says otherwise.
What clip length and shot length are allowed?
Source clips run from 5 to 30 seconds and no single shot may exceed 15 seconds, so split longer takes before uploading. The recast comes back at the same duration as the input.
Can I control who becomes whom?
You can bring up to four portraits, one per performer. By default they take the lead roles left to right; a prompt such as 'the woman on the right becomes person 1' rewrites that order.
Which photos give the cleanest results?
Sharp, front-facing, evenly lit images with no sunglasses, hats or hands over the face. A half-body frame transfers hair and clothing better than a cropped headshot; avoid group shots, heavy filters and low-resolution files.
Is it worth rendering at 1080p?
Run the 768p pass first to confirm every face reads correctly, then render the 1080p master for delivery. Cost follows how long the clip runs more than resolution alone.
Where does the tool stop being the right choice?
It will not invent new camera moves, new action or a new location. Crowded frames, distant faces, rapid motion and heavy occlusion also weaken the swap, and identity can drift back toward the original performer in long or profile shots.
Give a Finished Clip a Brand-New Cast on Fuser
Upload your photos, choose a take, and let the model hand the lead roles to new faces — timing, camera moves, edits and soundtrack remain exactly as shot. Compare MiniMax, Hailuo and Kling models, or read the guide first.
