There are three ways to release a claim in Content Manager:
Locate the claim in a list of claims or using the filters on the Claims tab. (A few claims may also be listed on the Overview tab.) On the Review Claim page, click the Release claim button that displays below the claim details on the right side of the page.
On the Review Claim page, click the Release claim button that displays next to the video image near the top of the page.
Using the Bulk Update tool, modify the usage policy for the claimed video to a policy that specifies that you do not claim the video's content.
