Yeah I did a few "<subject> in 60 seconds" videos and the two lessons I learned from that? (1) They take hours and hours and hours of work to make. (2) Your script for the video must not contain more than 50 words, so you can say very little.
Not surprising: According to https://en.wikipedia.org/wiki/Reading_(process)#Assessment reading for comprehension normally falls in the 200-400wpm range. 10 seconds to read 49 words is 294wpm, which is smack in the middle of that range.
(The above comment is 49 words)
