Watching and enjoying Sully's lecture, as usual.
The audio is better. But instead of mic'ing the space, use a line-in to eliminate the echo, as well as the near-field movements of the audio tech.
Also, tie into the chart presentation. Have two panels, one portrait mode on the left side with Sully, and another landscape mode in the rest of the frame with a direct feed of the charts.
Sully's presentation is worth the effort.
For posterity and ages to come.
