I can't find the video in the Clipping Plane description

Let me ask you a question.
In the Clipping Plane description, it says "Refer to the video below", but I am not sure which video you are referring to.


Also, there are some explanations in places that refer to sections not linked on this page, but it would be easier to understand if you could link to them.

I'll begin correcting this tomorrow, @tokufxug . Thank you!
