Put music on a video and choose how loud it is next to the video's own sound, with the music repeating and fading out at the end.
Recording a voice over it instead? Use the video maker. Need just part of the song? Cut it first with the audio cutter.
No. The picture is copied exactly as it is, without re-encoding: only the sound is replaced, so it is quick too.
Yes. Set the video's own sound and the music volume separately, for example 100% voice and 30% music behind it, or turn the video's sound down to 0% for music only.
Keep “Repeat the music” ticked and it starts again until the video ends. It fades out over the last seconds unless you untick that.
No. The video and the music are mixed in your browser.
