Quicktime sucks.
True HD on the net most likely is not true HD.
Just because it is in 16x9.
True HD is 60FPS in either 720p or 1080i depending on what spec your camara is conformed to.
Now think about that for a minute.
What most of you are seeing is not really HD but emulated.
Don't get me wrong its still kick ass no matter what but to call it HD is an insult.
Shot by me.
Sample
Emulated of course and frame rate dropped.
