[Interest] Where'd the videos go?

[Jason H]

I am searching for a talk about QML/Qt models and JSON data from either a Qt World Summit or a contributor's conference. Someone has a really good take on models, and I'm trying to find it. I went to http://www.qtworldsummit.com/cpt-sessions/effective-qt/ but this takes me to a general marketing site now.

I'm hoping to find a list of all the videos of all the talks of all the years so I can find the one I'm looking for. Does this exist anywhere?
