The video was blocked. How Youtube zvld control billions of videos

Bn users often did not hear about Content ID. The cars support him because they raised billions of dollars thanks to him. A nkte s nm svd fight, when he blocks them first. Take a look at the working software that, as an Internet forensic scientist, monitors copyright protection on YouTube.

How is it possible to find some dogs on YouTube only from the original author and look for others many times on different channels?

Anyone who has ever uploaded a video to YouTube may have found that it has been muted or completely erased. The server relies on two things in the author’s first check. Edges to the user community, which is particularly inappropriate even the first violating video to report to me. Following me, I approved to drink a similar one at first:

While the user discovers inappropriate video, the main weapon against abuse is specialized software Content ID. It was launched by Google in 2007, a year after the YouTube platform came under light. To understand how it works, let’s first briefly imagine music recognition software.

Music recognitionDecomposition of sound into data

The sound recognition program is yesterday and each detection approach is different. Some rely on rhythm and tempo analysis, other frequency and amplitude, or even oriental points, which are characterized by a marked change in acoustics. However, it must always decode the audio track to measurable data.

If you want to convert a few seconds of sound to this data source, you need to have something to deal with quickly. Programs use an algorithm for analysis, among the recognition mechanisms the technique called Rychl Fourier transform most often leads. It manages to perform a flash data analysis, find characteristic differences (tempo, volume) and generate a unique track (usually in wild form).

The programs thus create a database of original records. Then, if you want to find the name of a dog, make the program available. It performs the same analysis as the original and the following algorithm compares the track with those in the database. Determine the probability of a match and the user of the program can choose the limit at which the software will report the match (eg to 95%). And you can simplify it and look directly at Content ID.

We could compare the work of software to criminologists who use a method called dactyloscopy. Get a fingerprint in place of the crime, scan it and compare it with the database. Once there is a match, the perpetrator is one foot behind the meme, because each fingerprint is unique.

The copyright owner of YouTub can provide its creation (audio and / or visual track). Content ID provides a digital imprint of its page sounds, in the case of the video itself it is divided into thousands of images.

The quantum collects this information in one large database. Once you upload a video, the software automatically compares its track to the fingerprints of the original videos. In order to make it easier to compare faster than cadence, hacked by Google Brain tm, a group of programmers who are in charge of, for example, the algorithm for recommended video. Even the Content ID works on a neural network, which, once it finds a match, notifies the owner of one of the partner platforms (AdRev, Audiam).

The original author has a lot of options that you can preset. Some owners may find statistics from your video (such as in which countries the video is watched, etc.). The most common choice is the tolerance of the video and as a punishment the system inserts advertisements into it, their profits go to the owner, especially musicians and singers. Another option is to mute the audio or block the video, which is usually accessed, for example, by studio movies.

How to armor?Even the master program sometimes falls apart

Thanks to the program and inserted ads, the author has raised billions of dollars. Only the software blows me away. Doke can compare not only an exact copy of the sounds of a track, but also melodies. What can be a problem, for example, for users who upload the songs of original songs.

And this is where the problem sometimes arises – Content ID is a program that is missing. And I can recognize agreement even where it is not. In this case, the user has the opportunity to arm with a counter-name, which directly manages the service.


Problems and until recently were not only in the program, but also complaints. The processing took thirty days, and although the user did not use foreign material, during this time the video was blocked or the advertising proceeds, which went to the author. In April 2016, therefore, YouTube played with eenm.

Today we prick with a sticky glue. As soon as the author of the video and the complainant (both the original author) decide to insert ads into the video, the pensions will not go to either of them, but we will isolate them in a special penny. After clarifying the situation, the pension was transferred to the first-time owner, the product manager David Rosenstein announced at the time.

Therefore, if it is blocked first and after the counter-notification the complaint is withdrawn, the pensions from the added advertisement will go back to the author of the video, not to the searched owner for the same recording.


Content ID recognizes a false match and a real match, on the contrary, does not detect it. Last year, the International Federation of the Music Industry claimed that the system would not recognize 20 to 40% of its holdings and would lose profits. During the program’s existence, the user learned how to get around it, and he tried to keep up with the tricks and adapt. Using known techniques, it was accelerated by a few hundredths, easily raised and gave tricks that we will not describe here.

We had two problems with these handles. But today, the system can learn much faster how to recognize these deceptive techniques, to one of only Harris Cohen’s darkness.

Sound libraryFree music to videos

If you want to create videos with ads, how do you sound handcuffed? YouTube has created an Audio Library for this. You can access the complete music database in the Studio for Authors section under the Create folder.

You can search for free music by number, instrument or even mood. In the second place, you can find sound effects in which you can browse by category or use full-text search. The recordings can be downloaded for free or if you are playing the sound more often, it can be added to the favorites by clicking on the star.

Let’s take a look at what it’s all about: pensions and the functioning of the YouTube advertising system.
