No matter what kind of video creator you are, copyright directly impacts the videos you make, and the way

you use YouTube. Today millions of people around the world upload their own videos to YouTube.

They document world events, create home movies, and make their own independent films.

And sometimes, even though it's against our rules

Fans pay tribute to a new hit song they love, or their favorite movie or TV show.

By uploading videos to YouTube that use content created by others.

So how can copyright holders identify these uses of their content on YouTube, control them, and even take

advantage of these new forms of user distribution? The answer is Content ID. The system we've built that

gives copyright holders choices about whether and how their content is shown on YouTube.

Here's how it works: copyright holders give us copies of their audio recordings and videos that

they want to look for on YouTube.

We call these copies reference files,

and put these files in a database. This database contains over three million files, from pop songs to

full-length movies. Every time you upload a video to YouTube, we quickly compare it against every reference

file in our entire database, looking for a match. Content ID can identify audio matches,

video matches, partial matches,

and can even identify a match when one video's quality is worse then the other. Each time Content ID

finds a match,

we do what the copyright holder asks us to do with that video. Either block it,

leave it up, or even start making money from it. With over twenty-four hours of video uploaded to

YouTube every minute,

Content ID works around the clock

It scans over one hundred years of video every day.

it's like thirty six thousand people staring,

without blinking,

at thirty six thousand monitors. All day. Every day.

Now, copyright management is easy and accesible for everyone.

Artists can let fans re-use their content.

And fans can create promotional and business opportunities for their favorite artists --

making Content ID a true win-win that enables new forms of creativity and collaboration aournd the world.
