What are the "standard" YouTube video sizes?

by 2 comments
YouTube seems to be in a constant state of flux. As far as I know, the "standard" sizes now being used on YouTube are:

640 x 360 (for 16:9 "widescreen" video)

AND

640 x 480 (for 4:3 "regular" video)

Is this still the case, or am I "behind the curve," again?

Also... most YouTube videos have a pixel aspect ratio of 1 (square). However, for HD should the pixel aspect ratio actually be 1.2 (with a 4:3 frame ratio)? Anybody know?

Thanks,

Johnny
