Aspect Ratio


 * Do not get confused between “frame aspect ratio” and “pixel aspect ratio”. They are quite different. See the following:
 * This tutorial for details on correctly working with aspect ratios in CS4 and later.
 * Aspect ratios in the Premiere Pro CS4 Help.
 * Aspect ratios especially About aspect ratios in the Premiere Pro CS3 Help.
 * “About aspect ratio” in the Premiere Pro 2.0 Help.
 * “About aspect ratios” in the Premiere Pro 1.x Help.

 * If you want the old (CS3) aspect ratios to take effect in CS4, simply select DV 16:9, then go to the general tab. Change the Editing mode to Desktop, and change 720 to 702.

 * PAR has been a discussion internally during this cycle, and I agree that the current PARs used in Premiere (actually, all the products for that matter) aren't 100% accurate. We're trying to do a product-wide change to address this in our next release.FWIW, these are our agreed-upon ratios going forward (we're basing ourselves on information that can be found in "Digital Video and HDTV, Algorithms and Interfaces" by Poynton, for those who are curious):Square Pixels (1.0) 1 : 1D1/DV NTSC (0.9) 10:11D1/DV NTSC Widescreen 16:9 40 : 33D1/DV PAL (1.067) 59 : 54D1/DV PAL Widescreen 1024 : 702Anamorphic 2:1 (2.0) 2:1HD Anamorphic 1080 (1.333) 1920 : 1440DVCPro HD (1.5) 3 : 2

 * And when you change the size of the frame, make sure the lower number is divisible by 72. That makes it divisible by both 8 and 9. So, some of my favorites are 512X288 and 640X360
