How AI Video-to-Audio Conversion Works
Upload Your Video File
Drag and drop any MP4, WebM, or MOV file up to 25 seconds. Silent videos work perfectly — no existing audio required.
AI Generates Matching Audio
Our AI analyzes the visual content of your video — the environment, objects, movement, and scene — and generates new ambient sounds that match what it sees.
Download MP4 with Audio
Download your video as a single MP4 file with the generated audio embedded. Ready to share on any platform.
AI Video-to-Audio vs Traditional Converters
Traditional video-to-audio converters extract existing audio from your video file. Dobidy does something different — our AI watches your video and generates new ambient sounds that match the visual content.
