AI Video Generator with Native Stereo Audio

Direct Picture and Sound Together

MiniMax H3 can generate video and native stereo audio as part of the same scene. The sound direction should support what is visible. Describe the source, distance, intensity, and timing of important sounds rather than adding a long list of unrelated effects.

Four Useful Sound Layers

1. Ambience: wind, room tone, traffic, rain, crowd noise, or forest insects.
2. Action effects: footsteps, fabric movement, machinery, impacts, doors, or water.
3. Voice: a short line, whisper, announcement, or background conversation.
4. Music direction: restrained percussion, distant strings, electronic pulse, or no music.

You do not need all four layers. Two clear layers are often more controllable than a crowded soundtrack.

Examples

Quiet interior

A baker opens a small shop before sunrise, locked medium shot, warm practical lights, soft refrigerator hum, paper bags rustling, no music.

Action scene

A motorbike accelerates through a wet tunnel, low tracking shot, repeating overhead lights, engine rising from left to center, tire spray and deep tunnel reverb.

Dialogue moment

Close-up of an astronaut looking through a fogged helmet visor, slow push-in, radio static, she quietly says “I can see the lights,” restrained low synth tone.

Tips for Better Audio Direction

• Link each major sound to something visible in the frame.
• Use distance words such as nearby, distant, behind, or approaching.
• Keep spoken lines short for a short clip.
• State “no music” when ambience and effects should remain exposed.
• Review with headphones and speakers before publishing.

Native audio can still vary between generations. Avoid presenting generated speech as a real person without permission, and confirm that music and voice use complies with applicable rights and platform rules.
