Google today launched a new feature in the YouTube Audio Library that allows uploaders who use copyrighted music to see exactly what will happen to their videos before they upload them.
When you upload a video to YouTube today, the service’s Content ID system will automatically try to figure out if you’re using any copyrighted music in it. Artists and labels can choose to then either mute that audio, block the video from being seen, or (if they’re smart) monetize the video by running ads against it. The problem with that is that until now, you didn’t know what would happen to your video until after you had uploaded it.
