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

0:00:05.990,0:00:11.360
you use YouTube. Today millions of people around the world upload their own videos to YouTube.

0:00:11.360,0:00:17.000
They document world events, create home movies, and make their own independent films.

0:00:17.000,0:00:18.880
And sometimes, even though it's against our rules

0:00:18.880,0:00:23.769
Fans pay tribute to a new hit song they love, or their favorite movie or TV show.

0:00:23.769,0:00:26.980
By uploading videos to YouTube that use content created by others.

0:00:26.980,0:00:32.689
So how can copyright holders identify these uses of their content on YouTube, control them, and even take

0:00:32.689,0:00:38.640
advantage of these new forms of user distribution? The answer is Content ID. The system we've built that

0:00:38.640,0:00:43.460
gives copyright holders choices about whether and how their content is shown on YouTube.

0:00:43.460,0:00:48.640
Here's how it works: copyright holders give us copies of their audio recordings and videos that

0:00:48.640,0:00:50.720
they want to look for on YouTube.

0:00:50.720,0:00:53.270
We call these copies reference files,

0:00:53.270,0:00:59.550
and put these files in a database. This database contains over three million files, from pop songs to

0:00:59.550,0:01:04.839
full-length movies. Every time you upload a video to YouTube, we quickly compare it against every reference

0:01:04.839,0:01:11.140
file in our entire database, looking for a match. Content ID can identify audio matches,

0:01:11.140,0:01:14.120
video matches, partial matches,

0:01:14.120,0:01:19.220
and can even identify a match when one video's quality is worse then the other. Each time Content ID

0:01:19.220,0:01:20.300
finds a match,

0:01:20.300,0:01:25.270
we do what the copyright holder asks us to do with that video. Either block it,

0:01:25.270,0:01:30.650
leave it up, or even start making money from it. With over twenty-four hours of video uploaded to

0:01:30.650,0:01:32.090
YouTube every minute,

0:01:32.090,0:01:34.190
Content ID works around the clock

0:01:34.190,0:01:37.420
It scans over one hundred years of video every day.

0:01:37.420,0:01:39.980
it's like thirty six thousand people staring,

0:01:39.980,0:01:40.880
without blinking,

0:01:40.880,0:01:45.890
at thirty six thousand monitors. All day. Every day.

0:01:45.890,0:01:49.720
Now, copyright management is easy and accesible for everyone.

0:01:49.720,0:01:52.920
Artists can let fans re-use their content.

0:01:52.920,0:01:57.300
And fans can create promotional and business opportunities for their favorite artists --

0:01:57.300,0:02:03.810
making Content ID a true win-win that enables new forms of creativity and collaboration aournd the world.
