I have been reading posts that deal with the question of Resolution of HDTV, 35 MM Film, etc. I thought it might be helpfull to put down some of the facts...and myths of Resolution. First off, resolution is determined by 3 factors: 1. How many lines make up the image (called Vertical Res.) 2. How many Pixels can fit on a line (called Hort. Res.) 3. How many images are shown in a second of time (called Frame Rate.) 35 MM film according to Eastman Kodak is measured at 2000/2500/24. That means 2000 lines with 2500 pixels per line at 24 frames per second. Sounds impressive but where film falls off is the size of the image that is projected at the local Cinema. To fill the screen the frame of 35 MM film has to be blown up to over 200,000 times its normal size. In large theaters like in LA and NYC to it over 300,000 times. HDTV is 1080/1920/30. This is considered 1080P with the P meaning Progressive. This means that a complete frame is shown once every 30th of a second. 1080I is interlace which in reality shows a complete frame every 15th of a second. It is the interlace process that fools the eye into seeing a higher frame rate than actually exists. These are the 2 most popular types of HDTV and it is really too bad that the third type 720/1280/60 has fallen by the wayside because if you look at the last number...the 60...it represents 60 frames per second which is the highest frame rate ever used for commerical purposes. Douglass Trumbull, a former special effects master (2001, Blade Runner, Star trek The movie) invented a film process called Showscan. It used 70 MM film running at 60 frames/sec. For anyone who has ever seen this and I have, It is reality...period. It matches the resolution of what the human eye can see. It was to be showcased in the movie Brainstorm but was not used. It became a short lived blip on the radar screen of film technology dominated by IMAX ( as far as quality of image). So what is "enough" resolution? Can you see the difference between 1080I and 1080P? The answer is yes...and no. It depends on the size of your viewing screen. On a 50"...maybe. On a 144" ..definitely...on a 34"..I don't think so. Hope this helps.
