Unable to download 360p video?

I am experimenting with Youtube-dl, and trying to fetch a science playlist.

According to the help (call youtube-dl with -h) you need brackets around the height parameter, it also shows quotes around it, like this:
youtube-dl -f "[height=360]"
I believe the quotes are for if there are spaces in the argument, might not always need them but safer to put them anyway.

youtube-dl -f "[height=360]"

Aha! That (the brackets) did it. Thank you.
Somehow, I thought those were only for an expression.
