Frequently asked questionsUseful details
4 answers +
Can I keep the original sound?
Yes. Mix keeps the video's own sound and plays the music under it at 35% by default; raise or lower it with the volume slider. Replace drops the original sound. A video without sound always gets the music as its only sound.
Can I start the song from the chorus?
Yes. Play the song, pause at the chorus and press Start song here, or drag Song starts at. Then play a video preview: the song plays along from that moment, at the chosen level, so you can check the mix before saving.
Which music can I use?
Any audio file your browser can decode, up to 15 minutes. Make sure you have the rights to use the song where you post the video; platforms may mute or block copyrighted music.
Is my video uploaded?
No. The video and the music are read and mixed in your browser on this device, and there is no watermark.
