Frequently Asked Questions
Will the music replace my voice?
No. The recording's audio stays, and the music is mixed underneath it. A silent video just gets the music.
Can I use the built-in tracks in my video?
Yes. Carefree, Local Forecast, and Floating Cities are by Kevin MacLeod (incompetech.com), licensed under CC BY 4.0. Credit him in the video description.
How loud should the music be?
Start at 15%. The voice should stay easy to hear. Turn it up only when the recording itself is quiet.
Is the file uploaded?
No. FFmpeg runs in your browser. The video and the music stay on your device.
