What if the song is longer than the video?

It's cut where the video ends. A shorter song loops until the end.

Can I keep the original voices?

Yes — choose Mix and lower the music volume so speech stays clear.

Only use music you have the right to use — your own recordings, licensed tracks or royalty-free music.

No. The video and music are combined in your browser — nothing leaves your device.
