Just concluded our summer semester - 2 classes - taught entirely on zoom. Lots of prep time for each session, in fact way more than I anticipated - approx 4:1
The Zoom platform is pretty cool. I used the "connect the phone" feature for demonstrating simple blocking for a two person table scene. As a class, we shot numerous angles of the dolls (32 shots) that I uploaded for them to edit together, adding the story, the voice overs and any additional B Roll footage they needed to complete their tale. The results were really entertaining!
Filmic Pro is an amazing APP that has tons of photographic features that are applicable to cinematography. It's a superb, affordable teaching tool that I will continue to employ for demonstrations and weekend projects.
