Most of that is because those are hard requirements to fulfill for most professors. Video production is pretty difficult to do well. The university I teach for basically offered no help in that realm in our transition. They basically just told us we had to transition to online in two days, gave us some bullcrap professional development on how to use Canvas, and then fed us to the wolves.

Make sure to blame the university, not the professors. We're trying our best with almost no help.
