Owners can manage their copyright interests on YouTube either by issuing a copyright takedown, or, if they have access to the Content ID tool, by claiming a video and setting a policy to track it by collecting stats, monetize it by placing ads and collecting ad revenue, or block it by making it unavailable in some territories. A Content ID claim isn't accompanied by a copyright strike, but a copyright takedown is. Since January 2014, Content ID claims have outnumbered copyright takedowns by more than 50 to 1.
Copyright law requires sites like YouTube to process takedown requests and describes the process we must follow. A copyright takedown requires the owner to submit a formal notice to us with all the legal requirements filled out.
In your copyright notices, you'll see the phrase "Video taken down: Copyright strike" beside your video if it was removed as the result of a copyright takedown notice. If your video was removed through a copyright takedown notice, a copyright strike has been applied to your account. If it's your first strike, you'll need to complete Copyright School.

If your video was removed in error through a copyright takedown, you have the options to:

Content ID claims
Unlike takedowns, which are defined by law, Content ID is a YouTube system that is made possible by deals made between YouTube and content partners who have uploaded material they own to our database.
You'll know if your video is affected by a Content ID claim if, in your copyright notices, you see the phrase "Includes copyrighted content". Usually, the claim is just to track or monetize the video, not to block it. So, your video remains live with those claims (but may have ads on it) and you can still share it with others.
Content ID claims don't result in copyright strikes, channel suspensions, or channel termination. However, if you believe a claim was made in error, you can dispute the claim. Learn more about Content ID claims.
