Recording participants moves in an online yoga class

[susiewise]

Thanks in advance

I have been teaching yoga online  and recording my classes for a couple of years on zoom for students to watch later. Even though I pin participants when I play back the recording it only captures me talking on the recording and not the participant doing the moves, which for folks watching later who are visual makes it tricky...

I am recording to cloud, any clues what I am doing wrong?
