Questions
How long can a YouTube Short be?
Up to 3 minutes, but 15–60 seconds of the strongest part of a song works best. Use "Best 30 s" to get it automatically.
Is it really free?
Yes. Make and download as many videos as you like, up to 4K. A small PulSound mark appears for a few seconds at the start and end of the video.
Who owns the video?
You do. The video is made on your device from your music; use it anywhere, including monetized YouTube channels.
Do you upload my track?
No. Your audio, images and the finished video never leave your computer — everything is rendered in your browser. There is nothing to install either.
