MiniMax H3 Max Insert
MiniMax H3 Max Insert from MiniMax splices a newly generated scene into an existing clip. Pick where the cut starts and where the original footage resumes, describe the scene or guide it with up to five reference images and three reference videos, and H3 Max generates 5 to 13 seconds that pick up from the footage before the cut and hand back to the footage after it, with optional color matching across both seams. Sources run up to 60 seconds, and the edited clip keeps the source's shape at 480p or 768p. Built for adding beats, reaction shots and story moments to game trailers and cutscenes without reshooting the take.
