Hi l van Veem,
You are correct the movies are hard to see and hear.
Here is a video of my presentation at Boston's userR! Meetup: "Boston useR! Meetup QuantileRegression Workflows 2019.04.18". (More details for that meetup are given here.)
The video is about using R and the package QRMon-R I implemented. But I do refer and use Mathematica examples with QRMon.

The movies are difficult to see on the projector screen unfortunately. Looks like a nice workshop with slot of effort going in to it!
