Translated from 日本語 • View original I tried the new editing feature "Face Blurring" added to YouTube (a function that automatically blurs people's faces), so I will write a review of it.
As for my impression, "The accuracy is not very good."
It may also be that the video from the source was not optimal... There were many cases where the blur was not applied when the image was slightly withdrawn enough to still recognize the face, or when the camera panned with a little bit of camera shake or speed. Also, the baby's face was almost unrecognizable and did not blur.
However, I also thought that it would be a very useful feature if the filtering process was faster than I expected and the accuracy was improved. Nowadays, there is a strong trend towards portrait rights and personal information protection, so I would like to see this tool strengthened.

Now, how to use the automatic "face blur" function, first log in to YouTube and "manage videos" (button on the top right of the screen).

Next, select "Video Enhancement Tools" from the "Edit" drop-down at the bottom right of the thumbnail of the video you want to edit.

Then, press the "Additional Options" button under the preview video area of the Quick Edit tab, and a tool menu called "Blur All Faces" will open, so press "Apply" there.

The video preview will start, with the original video on the left and the blurred video on the right.
It is quite easy to edit. It would be nice if there was an extension that could say "only certain people are not blurred", but it would be difficult because it requires a fairly advanced level of facial recognition processing.
