Looks like I opened up a can of worms :) To answer some questions it appears that there are true pixel aspect ratios, and then there are approximate pixel aspect ratios that are better for digital video editing software, and the true pixel aspect ratios are defined differently by different groups.
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
