I wrote a transcript for a video for you previously, I get it's shit when captions don't exist at all, I was just trying to help. I did actually watch it without sound for a bit and was surprised it was OK for auto-generated captions which are usually garbage.
Try and watch it without sound, you’ll find yourself struggling to follow it keeping your eyes glued to the bottom of the screen.
The reason you find them acceptable is because you can hear them.
