#Aspect Ratios
5 messages in this thread
I am looking for correct aspect ratios for all common resolutions
between 640×480 through 2048×1536. Has anybody published any info on
this before? The 3ds manual does not really cover this much.
Basically, the standard computer monitor resolutions (non-video) all
use a pixel aspect ratio of 1.0. This includes 640×480, 800×600,
1024×768, 1280×1024, 2048×1536. Pluss, pretty much anything you do
for print will also use a 1.0 aspect ratio. It's only video aspect
ratios that tend to be custom.
Gary,
Thanks for the aspect info, this is as I expected…..but wanted to be sure.

The 3D Studio manual does a pretty poor job of covering this issue.
Newer video cards do make life simple with 1.0 aspect ratios, but
standard VGA (and the basic AAPLAY flic player) use an aspect ratio
of 0.82. Life gets really wierd if you have a flic (0.82) that you
want to print (1.0) or show on a different monitor (1.0) and then
need to send out to a video frame buffer (1.23, 1.27, 1.05,…)!!!
Also, some image files are saved with explicit aspect ratios and are
corrected for whatever display or print automatically, and some are
not! As far as I know, there is no handy, idiot proof, one-step way
to convert images and animations between different aspect ratios.

Thanks for your input on this sometimes confusing issue. My main
concern at this point is with the correct aspect ratios for still
images. When I need to go to video, I will follow the expert advice
offered here on the forum (which has never led me wrong). I will
continue to use the 1.0 aspect ratio for all resolutions for stills
as advised by Gary Yost.
