PyCon 2015 - were all the talks recorded?

[Chris Angelico]

Geography prevented me from attending PyCon 2015, but I would have
loved to see some of the talks, particularly the one by Paul
Hildebrandt of Disney [1]. There's a Youtube channel for "PyCon 2015"
[2], but searching by speaker's name, "Disney", and "Inside the Hat"
brought no results. Must I assume that this talk was not recorded?
It'd be a great pity.
