More about this tool
How it works
1. Upload your video clip (MP4, MOV, MKV, MPG or TS).
2. If you like, describe what you want to hear, such as "horses galloping" or "rain on a tin roof".
3. Click generate. The AI watches your footage and creates sound effects that match the action on screen.
Tips for better results
• Clips with clear, visible action (footsteps, waves, engines, animals) give the AI the most to work with.
• A short prompt helps set the mood, for example "quiet forest ambience with birds".
• Music is left out by default. To keep other sounds out too, list them in the negative prompt under the advanced settings.
• Not quite right? Run it again. Each run uses a new random seed, so you get a fresh take.
Good to know
What kind of video is this for?
Any time you need to add audio to a silent video: AI-generated clips, screen recordings, or footage whose sound was lost or removed.
Do I have to write a prompt?
No. The AI can choose sounds from the picture alone. A prompt just gives you more control over what you hear.
Will it add music or voices?
It is made for AI sound effects and background ambience, not for composing a soundtrack or making people speak.
Which file types can I upload?
MP4, MOV, MKV, MPG and TS video files. It's an easy way to add sound effects to video without hunting through sound libraries.
