Youtube Copyright
In terms of youtube copyright, it is of great importance to understand about a Youtube copyright strike and a content ID claim.
First, if you get a copyright strike from YouTube for one of your videos this means that it has been taken down from the community following a valid formal legal request from the copyright owner requiring YouTube to do so under the Digital Millennium Copyright Act.
There are two options for you if you want to deal with a YouTube copyright strike, namely, contacting the copyright owner to retract their infringement claim or submit a counter-notification if you believe your video was mistakenly removed as it is made for fair use or was simply misidentified as infringing copyright.
Regarding a content ID claim, if a video is uploaded including copyrighted material the YouTube account owner could issue a Content ID claim. These are issued by companies that are copyright owners to movies, music, television shows, video games, and any other copyright-protected works. With a Content ID system, copyright owners are enabled to quickly and effectively identify their works on YouTube. When a new video is uploaded to YouTube, it would be scanned against a database of existing works submitted by content owners. Content ID claims against your YouTube account are likely to be found in the copyright notices section of your Video Manager. In some cases, you may be notified of a Content ID claim via email.
There is a difference between a copyright removal and a Content ID claim. A copyright removal on YouTube requires the submission of a legal notice from the copyright holder, with all the necessary valid requirements fulfilled. A Content ID claim is not governed in law as a copyright removal. You can get to know a Content ID claim because the video will display a phrase: “Includes copyrighted content”. In most cases, the claim is simply to track or monetize the video and not block it entirely, which has no adverse impact on your YouTube account.
