I haven't been able to duplicate your problem. I use something like
ffmpg -s 1366x768 -f x11grab -i $DISPLAY -f alsa -i default output.mkv
(I get the 1366x768 from xrandr)
However, if it's defintely giving that pixelation you're describing,
there's a few options. I don't know much about youtube uploading, so not
sure why youtube-dl wouldn't get the captions, whenever I've used it, say,
with anime, I've bee able to get my captions.
There's an extension for firefox, downloadhelper, that I have found useful
in the past.

Also, are you using the latest youtube-dl, that is, going to their site and
downloading it, or the one provided by your distribution? Sometimes, those
will be older versions and not work as well.
Depending upon what the video is, it may be available some other place
besides youtube--for example, if it's an anime, you may be able to watch it
on crunchyroll.
