MiniMax H3 AI Video Generator with Native Stereo Sound

MiniMax H3 is a general-purpose multimodal AI video model that generates picture and native stereo sound together. You can create from a text prompt, animate an opening or ending frame, or combine image, video, and audio references to guide the subject, motion, camera, voice, style, and editing rhythm. See Text to Video, Image to Video and Reference to Video.

Yes. MiniMax H3 can generate dialogue, voice, music, sound effects, and ambience as part of the same audiovisual result instead of adding an unrelated soundtrack afterward. Describe the sound in the prompt or add supported references when you need clearer direction for voice, performance, timing, or mood.

The browser generator supports 768P and 2K output with durations from 4 to 15 seconds. The available aspect ratio and sizing behavior depend on whether you start from text, a frame, or a multimodal reference set, so choose the input mode before setting the final output.

Yes. A reference-to-video request can combine images, video, and audio in one creative context, with up to 12 files in total. State what each reference should control, such as character identity, product appearance, camera movement, voice, visual style, or rhythm; an audio reference must be paired with at least one image or video reference.

You can add up to 9 images, 3 videos, and 3 audio clips while staying within the 12-file total limit. Video and audio references allow up to 15 seconds per media type. Use only references with a clear purpose, because overlapping or contradictory direction can make the intended subject, movement, or style less clear.

Yes. Add an opening frame, an ending frame, or both, then describe the action, transformation, camera movement, and sound that should connect them. The supplied frame controls the composition and output ratio, making this mode useful for reveals, transitions, film openings, and planned visual story beats.

Text-to-video supports six fixed aspect ratios ranging from cinematic 21:9 to vertical 9:16. Frame-guided generation follows the supplied image ratio, while reference-to-video also supports adaptive sizing. Choose the ratio around the final destination, such as widescreen film, square social content, or vertical short-form video.

Yes. Add an existing clip as a video reference and explain which elements should remain consistent and which should change, including motion, character, scene, camera behavior, sound, timing, or pacing. This is instruction-guided generation rather than a frame-by-frame timeline editor, so focused directions work better than a long list of conflicting edits.

Audio references can guide voice, dialogue, timing, and performance, and prompts can direct how speech belongs in the scene. This browser generator does not advertise a separate one-click voice-cloning feature. For stronger audiovisual direction, use a clear reference and describe the speaker, delivery, action, and camera in the same brief.

Generation time varies with the selected output, request complexity, and current service load, so the site does not promise one fixed completion time. After you submit a task, the generator displays its processing status. Keep the page open until the result is ready, then review, refine, or download the generated MP4.
