Granted, *technically* anything over 480 vertical lines of resolution is HD but know your standards, man!
1280 is a monitor screen resolution.
Accepted HD formats are 720 and 1080.

I'd rather be ignorant than stupid. Ignorance implies a lack of knowledge which is easily correctable through education. Stupidity implies an inability to learn. Therefore; ignorance is temporary, stupidity is forever!
