Your Music and Sound Stay
The music and background sound of your own video are kept and the new voice goes over them.
Fit to Your Length
The new audio is fitted to the length of your video: trimmed if longer, padded with silence if shorter.
Lip Match for On-Camera Speakers
If a speaker is on camera, add lip match so the mouth follows the replaced words.

Replace Audio in Video FAQ
How do I replace a voice-over and keep the music?+
Upload your video, choose Use another clip's audio, add the clip with the new voice-over and pick Just the voice. The voice of the new clip goes over the music and background sound of your own video.
How is this different from swapping the whole audio?+
Everything replaces the entire soundtrack with the other clip. Just the voice takes only the speech of the other clip and keeps the music and sound of your video.
Is the music cleanly separated?+
The voice and the music are separated by AI and that is not perfect: a little of the music can remain with the voice, or a little speech in the music. Listen to the result before you use it.
How much does replacing the voice cost?+
2 credits per started minute to take just the voice or just the music of another clip, and lip match is added if you choose it. The price is shown before you run.
What if I just want a different voice, not a new recording?+
Use Change the voice instead: the words and timing stay and a preset voice, a saved voice or a voice from a clip says them.
How long can the clips be?+
Clips up to 2 minutes. Trim a longer clip first.
Do I need a subscription?+
No. You can pay as you go: credit packs are one-time purchases and their credits never expire. If you would rather have a steady supply, the monthly Starter ($7.99), Creator ($19) and Pro ($49) plans refill your credits each month, and you can cancel anytime. Unused monthly credits do not roll over.
