the issue is that it is a multiplier problem. you have resolution x scale x broadcast standard x interlacing x anamorphic x framerate mostly, so its like two or three choices per means 3^6 possibilities. e.g., 1920x1080 x .75 x NTSC x i x anamorphic x 30 as just one possibility.

Based on my reading it sounds like we should be using the following NTSC 4:3 -> 10:11 NTSC 16:9 -> 40:33 PAL 4:3 -> 12:11 PAL 16:9 -> 16:11 http://www.mir.com/DMG/aspect.html http://en.wikipedia.org/wiki/Pixel_aspect_ratio#Pixel_Aspect_Ratio_of_Common_Video_Formats LetterRip _______________________________________________ Bf-committers mailing list [email protected] http://lists.blender.org/mailman/listinfo/bf-committers _______________________________________________ Bf-committers mailing list [email protected] http://lists.blender.org/mailman/listinfo/bf-committers
