AI Video Generator with Matching Audio in One Step
Wan3 generates audio with the video, so footsteps, waves, crackling fire, or city ambience come out generated to match what's on screen.
How It Works
Write a prompt or upload an image in the creator.
Describe the scene, including what it should sound like.
Generate. Video and native audio come back together as one MP4.
Native Sound Effects and Ambience
The model generates audio to match the visuals: environmental sound, motion sounds, and atmosphere. Choose W3.0, W3.0 Pro or Prime Pro (members), or Seedance 2.5. 4K is available on W3.0 Pro and Prime Pro; 1080P and above need an active membership.
Why Generate Video and Audio Together
No separate stock-sound search and no extra audio step in an editor. Useful for social clips, product teasers, and mood studies where a silent video feels unfinished.
Writing Prompts for Sound
Mention sound sources directly: "rain on a tin roof," "espresso machine hiss," "gulls over a harbor." Keep the visual and audio direction consistent.
