MiniMax H3 Recast

It replaces the people in an existing video with the people in your reference photos. The source motion, camera work, cuts and audio are kept, so it's a casting swap on finished footage, not a new generation. By default, photos replace the main people from left to right in every shot they appear in.

Between 5 and 30 seconds, and no single shot may run longer than 15 seconds. Split long takes first. The recast keeps the length of the source.

Up to four, one photo per person. Photos replace the main people from left to right by default, so order them to match screen positions. Add a prompt such as 'the woman on the right becomes person 1' to override the order.

One sharp, front-facing, evenly lit photo per person. With no prompt, Recast tends to bring in the photo's hair and clothes, even from a cropped headshot: in our test on 23 October 2026 (one run, 768p), a forehead-to-chin photo still turned the source's silver hair black and her rust cardigan sage green. To swap only the face, add a prompt such as "Replace only the face of the woman with the face from the photo. Keep her hair and clothes exactly as they are." In the same test, a prompt along those lines kept the hair and outfit and swapped only the face (see the face swap walkthrough). Avoid sunglasses, hats, hands over the face, group photos, and low-resolution or heavily filtered portraits.

Test at 768p, then render the final at 1080p. A short 768p pass confirms the casting and identity before you pay for the higher resolution, and cost scales with clip duration.

Skip it when you need new motion, new camera moves or a changed environment, since the source dictates all of that. It also struggles with busy crowds, small or distant faces, and fast action or occlusion after hard cuts. Identity can drift back toward the original actor in long shots or profile turns.
