4b. Collapsible green screen[0]. Can't recommend this enough if you don't want/have the ability to stage or curate your background (my "office" doubles as a guest room). It's also excellent for presenting and handy for any number of one-off things. When I don't need it I just slide it under the bed, easy.
What teleprompter do you use? How do you use it?
