What is MiniMax H3?
MiniMax H3 is an advanced AI video generation platform that creates short clips with native stereo audio in a single pass. Users generate 5 to 15 second videos at up to 2K resolution and 24 fps directly from text prompts or mixed multimodal inputs. The system reads text, images, video clips, and audio tracks together in one shared context, so sound, motion, and visuals stay tightly aligned without separate post production steps. MiniMax H3 supports four main workflows. Text to video turns a detailed creative brief into a finished shot complete with camera moves, lighting, dialogue, and sound. First and last frame mode lets users upload start and end images so the model fills the transition while keeping composition intact. Reference to video accepts up to nine images, three video clips, and three audio files to lock character identity, product appearance, motion style, camera language, voice, and rhythm. Instruction based editing allows targeted changes to existing footage, such as replacing a product or shifting time of day, while preserving the rest of the shot. The platform emphasizes production ready output suitable for advertising concepts, product films, social creative, game cinematics, and previsualization. Aspect ratios range from cinematic 21:9 to vertical 9:16. Credits are sold in one time packs with no subscription and never expire. Failed generations are refunded automatically. The first generation requires no card.
