Even before the advent of COVID-19, online classes were becoming very popular. Now it seems ever more likely they will be integral to how we teach our students going forward. I have been creating online classes for over 5 years now and have filmed researchers in one on one in green screen studios and huge seminar rooms with large audiences. Using multi-camera setups with recording equipment I capture the seminar, then use professional video and sound editing software to produce the online content. The classes are then uploaded to any video format or video hosting services such as YouTube or Vimeo. These can be viewed on multiple devices such laptops, tablets, smart TVs or even phones - perfect to prepare students on the way to class.
