Vimeo's announcement is quite thorough and informative as such important news to creators and rights holders should be. Regarding how Copyright Match differs from other content id systems:
Similar copyright-detecting systems are already in place on other video and audio-sharing platforms, but they’ve proven to be double-edged swords."
On the one hand, these systems help protect artists by cutting down on infringing uses of their works. Which is a good thing! On the other hand, the systems can stifle creativity by blocking material that’s being used with permission or that qualifies as a 'fair use' under copyright law."
Here's how Copyright Match works using Audible Magic's content recognition:
When you upload a video to Vimeo, Copyright Match 'fingerprints' a sample of its audio to see if it matches that of certain third-party copyrighted material, such as songs, movies, and TV shows."
If we find a match, we’ll present you with a few simple options. If you believe your video follows our guidelines, you can quickly and easily appeal the match by providing Vimeo’s moderators with more information. You can tell us that you’re using the material with permission, that your use of the material is protected by 'fair use' ...or that our Copyright Match system made a mistake."
You also have the option to replace the video file, delete the video, or, in the case where a music match is detected, swap the audio with a track from the Vimeo Music Store."
They have quite a bit more to say about both privacy and fair use. A variety of related materials are available from Vimeo:
