Interesting...and thanks for the answer. Forgive me for sounding like a novice, I'm just now beginning to work with video. I'm having a hard time wrapping my head around this though. Let's say one has a 120 minute movie, it would actually take up less bandwidth to encode large bars on the top and bottom (letterboxed) as opposed to very narrow bars (anamorphic)? I understand that solid black is easy to compress, but how can there be more actual picture information on anamorphic format as opposed to letterboxed format? Is it simply that the resolution is that much finer on anamorphic?
D.O.
edit: It looks like MeBe answered my questions on the very next post.
