How does the Content ID system work?
Every time a copyright holder’s content is delivered to Content ID, a digital fingerprint is created. The database is then scanned to determine if the audio and video fingerprint is used in uploaded videos. When the system finds a match, the video using the content gets a Content ID claim, and monetization (ads) will be turned-on for that video. YouTube charges advertisers on a per-click or per-display basis and shares the revenue with you, allowing you to make money from people viewing your videos and clicking on the ad links.
MusicDigi generates these automatically and associates them with your music for FREE. You don’t have to think about it.
And we’ll show you what your UPC and ISRC codes are, so if you want to use them for any other purpose, you’re welcome to.
