I was wondering what is the actual resolution of a 4:3 videos at 1080p?
For example the Wizard of Oz(1939) has the Aspect Ratio:1.37 :1 like a 4:3 TV.
But there is a blu ray that claims to be 1080P, but if you put it on a 16:9 1080P TV
You will have side bars, and will lose some of the resolution.
So what is the resolution of 4:3 at 1080p with side bars?
