Hello, everyone knows about audio watermarking of copyrighted sound on youtube but they also have a system that recognize videos. Does anyone know how it works and if I can erase the watermark.
Here is a sample that gets recognize, it's a 2 min clip without sound. I did some testing.
-Cropped 8 pixels top and bottom : is detected
-Reversed the video : not detected
-Flip vertically : not detected
-Flip horizontally : not detected.
