Size of movie screens, as well as aspect ratio, may vary. While standard TV ratio (4/3) is 1,33:1 (1,78:1 for 16/9), Cinemascope has an aspect ratio of 2,35:1 and Panavision rises to 2,40:1, known also as Super 35 or Anamorphic. Most used formats today are European Standard Flat (1,66:1 or 5/3) and Academy Standard Flat (1,85:1 or 5,55/3) They both rely on 35mm films and play back at a frame rate of 24fps. Different rules for Imax format, based on a 70mm film and playing back (with Imax Hd) up to 48fps. For what concern to resolution, consider that a standard 35mm frame can detail up to 18.000.000 pixels. If you plan to output to video, PAL ha 625 lines of resolution and 50 fields per second (25 fps). NTSC support 525 lines of resolution and 60 fields per second (29,97 fps). This apply to video composite signals only. Hope this can be helpful.
