On the other hand YT is full of various Peppa Pig videos (inverted colors, mirror images and all kinds of other weird transformations). YouTube's algorithm apparently can't detect such copyright violations. And the really annoying part is that these videos often rank higher than the original ones.

It's an interesting technical question, why video is so easy to change fingerprint, but audio isn't. I suppose it comes down to a few things:

* Video has higher dimensionality

* Distorted videos often have distorted audio (usually dialog) that would ruin the work if the audio was the primary value of the work.

but are the copyright violations then, there has been significant alteration done to the original work.

As the alterations are not transformative the existing copyright will still apply.

I would assume the characters themselves are copyrighted.

I guess trademarked.
