Add matching sound to a silent video

Many AI video models make silent clips. Video to Audio watches the footage and creates sound timed to the action, so the splash lands on the splash and the slam lands on the door.

A short list of sounds helps with things the camera can’t show, like distant birds.
You pay per second of sound, so set the length to match your clip.

Questions people ask

Does it keep my original audio?

No. The picture stays the same and the returned clip carries the newly generated sound as its audio.

Can it add music or speech?

It focuses on effects and ambience. For music, use the Music Generator; for a voiceover, use Text to Speech.

How long can the sound be?

From 1 to 30 seconds per run. Longer videos can be done in parts.

How much does Video to Audio cost?

Video to Audio starts at 1 credit per 5 seconds of video. The generator shows the exact price before you run it, and a run that fails is refunded automatically. New accounts get 30 free credits, enough to try it.
