Wonderful to have all this information..thanks so much. I have a LOT to learn.  I edit the video in YouTube Studio as you can cut out parts (not add parts) to it. I use the MAC iMovie application to add any parts. For many videos, I add punctuation to the YouTube captions. I like saving the recording to my computer, loading them to YouTube (Unlisted, using a link) and then deleting them from my computer. But I need to digest all your suggestions above. Thank you so much for sharing!
