Why are videos so difficult to find and keep?

I wanted to make a list of the videos I've recorded recently. 

I thought this would be what a youtube channel meant: a place where you put your own videos. I simply wanted to copy these videos from some other places. For example the talk I gave in the Logic SuperGroup, the one in the Proof Theory Seminar,  the one at the MIT Category Theory, etc. 

And it's probably just me being stupid, but this seems very hard to do.

Ok, the videos are very big and take a lot of space and of time to process. But surely, there must be an easy way to do something like what I want.

Anyways for the time being, here's just a collection of links to talks I've given.
