What format???? You don't know too much about it, do you?
It's shot on film, the resolution is endless. HD is a digital format with a relatively high resolution, film is analog. It's the transfer from film with an endless resolution to digital that makes something HD or not. Depending on the number of lines used to scan the film image, something becomes HD or not.
Well, I dunno. I am not convinced the HD revolution will happen so easily. In Europe they tried to introduce it some 15 years ago, but it failed terribly. I wonder how fast Blue-ray or HD-DVD will go. DVD definately had clear advantages over VHS. But what are the clear advantages of HD? So the picture is clearer... true, for me, I love it. But check out how the color setting of an average television in someone's living room... it's usually quite terrible. So these people have to see why HD is so much better than normal DVD???? I doubt it. It will have to be forced on us somehow. US legislation for HD was a first step in that direction.
Another clear change may take place in cinema's though. I do believe HD will take over from film eventually. Simply because it's cheaper to shoot on HD, transportation of entire movies is cheaper and easier and the copies don't get damaged after a number of runs. And in the end, HD projection will definately outdo normal filmprojection. In the cinema's it's a clear win-win situation.
And it sounds like you know quite a bit.
DVD's were more expensive, and VHS and VHS players (still got one) were more widely distributed, why pay more when some people don't even know what the other looks like?
I agree with the cinemas and that it would have to be forced for people to realize a true difference.
