If you go into the settings of the youtube player you can increase the speed to 1.25, 1.5, even 2.0 X speed. At 2X it’s too fast to understand but you can then turn on subtitles and easily read along.
Not as good as a transcript, but this helps me with the youtube videos.
Thank you very much. So glad there are smart FReepers like you to help this old lady out with the tech stuff.
