I'm wondering how many frame per second are shown during Hollywood feature films, like Star Wars? I know 30/sec. is the norm around here on th desktop, but what would a really good Short require? = )

Feature: 24 fps Video NTSC: 29.97 fps PAL: 25 fps I find 15fps is sufficient for the desktop HAWK999

My understanding of frame rates is as follows NTSC video 29.97 fps (close enough to 30) PAL video 25fps Film (as in movies) 24fps Hope this helps

Well heck, I guess you should try this question in the 2D/3D forum! -Kix

The other answer I got, for a Feature, is 60. Thanks Kix~ = )

How big is a movie screen, and what resolution will it reflect? = )

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.

Sorry, I meant the 2D/3D ANIMATION forum (duh!). -Kix

60 frames per second was the standard for a short-lived ultra-high resolution film format developed by (I think) Douglass Trumble. There's no current motion picture display format that I'm aware of that uses 60 frames per second as its display rate. Standard theatrical films project at 24 frames per second, whether 16mm, 35mm or 70mm. As for the resolution, there are various groups of thought on this subject. Your best bet is to get in touch with the lab your client will be using to convert your animation files to film and find out their specifications. Specs will change from lab to lab. I can tell you this; a single frame of motion picture resolution animation is going to eat up a HUGE amount of hard-drive space. (At least 5 meg per FRAME. And at 24 frames per second, that's at least 120 meg per second.) If you're going to be animating for theatrical motion pictures, you'll need to work smaller so you have a chance of watching the stuff near real-time on your desktop or laptop machine. Then, once you have all the motion correct, you can render the material out at film resolution. Hope this is helpful. And good luck with whatever the project is! - Dex
