Your Voice Is Kept
The voice of your own video stays, and the new music is mixed under it.
Your Picture Is Kept
The video stream is copied untouched, so only the sound under the speech changes.
Use Music You May Use
Take music from a clip you own or are allowed to use. Platforms can still flag copyrighted music.
Priced per Started Minute
From 1 credit · 2 credits/min with your voice · 6/min with a preset voice. 2 credits per started minute to take just the voice or just the music of another clip. You see the exact price before you run.
Honest limits
Clips up to 2 minutes. Trim a longer clip first. The music is separated from the speech by AI, so it is not a clean music stem and can carry a trace of other sounds. It is for speech over music, not singing or covers.
