## Frequently asked questions

How do I add music to a video?+

Upload your video, then an audio file, set the volume, and click "Add Music". The finished clip downloads as MP4.

Can I keep the original audio too?+

Yes. Set the original volume above zero and it will mix in with the music. At zero, the original is fully replaced by the track.

What if the music is longer or shorter than the video?+

The track is automatically trimmed to the video's length. If the music is shorter, it simply ends there. The video keeps its own length.

Is it free and without watermarks?+

Yes, no signup, no limits, no watermarks.

Do the files get uploaded to a server?+

No. The mixing happens right in your browser, so the video and music stay on your device.
