MiniMax H3 is built to let you edit a video the way a director gives notes — in a sentence. Swap a character, replace a green screen with a fairytale forest, relight a daytime shot into night, or rewrite a line of dialogue, and everything you didn’t mention stays pixel-stable. No timeline, no keyframes, no masking. That stability is what separates H3 from tools that regenerate the whole frame every time you tweak something. The same model also handles text to video, image to video with first/last frame control, and reference-based generation across six aspect ratios from 21:9 cinematic to 9:16 vertical. Start free and iterate shot by shot.
