It’s rough as it was meant to be an exploration of the process and effort required.
Planning the presentation is obviously really important. I sketched out the presentation on a sheet of paper beforehand and practiced a half-dozen times, but still felt very unprepared while recording.
It’s worth taking time to learn the tools (duh!), as it makes the presentation flow much better. I spent too long switching pen colours and clearing screens.
I still feel this is a powerful format, and can be useful not just for external videos, but for internal knowledge transfer and training.
