Lol. That was my reaction too. “Oh, shit, it’s a video - close”.
My issue with videos is that they are too slow for relaying information. I’ll be ok with it if there would be a two-sentence summary, after reading which I could decide if I want to watch it.
I suspect so that video says it’s that phone calls don’t relay the body language and that makes it more difficult to understand.
I have both and I think it’s better to know, independent of the outcome.
