Minimax H3 Recast

It is a cast swap rather than a generator: the portraits you supply stand in for the people already in your clip, while movement, framing, cuts and audio remain from the original.

Clips must fall between 5 and 30 seconds, with no single shot longer than 15 seconds. Split longer takes before uploading — the result comes back at the same duration you supplied.

Up to four, each with its own portrait. The tool matches them to the leads in screen order by default, so arrange uploads accordingly; a written instruction can override that mapping.

One sharp, evenly lit, forward-facing portrait per person. Half-body framing carries hair and clothing more faithfully than a tight head crop. Skip sunglasses, hats, covered faces, group shots and anything blurry or heavily filtered.

Yes — run the low-resolution preview to confirm the pairing, then render the deliverable at 1080p. Since pricing follows clip length, that first pass is the cheap way to catch a mismatch.

When the footage itself has to change — different action, camera work or location — since all of that comes from your source. Results also weaken with dense crowds, tiny or distant faces, fast motion, and objects crossing a face right after a cut; over long takes, or when someone turns to profile, likeness may drift back toward the original performer.
