MiniMax H3 is an AI video generator that creates cinematic videos from text, images, audio, and video clips. It processes multiple inputs simultaneously, combining up to nine images, three video clips, and three audio tracks in one request. The system interprets motion, camera movements, voices, and visual style to produce videos between five and fifteen seconds long at 24 frames per second, with resolutions up to 1440p and two-channel stereo audio featuring ambience, sound effects, music, and synced dialogue. The software supports aspect ratios like 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16. Text-to-video prompts accept up to 7,000 characters, while image-to-video features animate photos with controlled frames. Users can edit videos using plain-language commands to swap characters, adjust lighting, rewrite dialogue, and clone voices, with unedited portions remaining stable. MiniMax H3 renders text, logos, and UI elements precisely, making it ideal for ads, e-commerce, and brand films.
