Check out your camera up and right vectors. That is usually the way to
change pixel aspect ratio.

I'll punt on this one for now.

From the docs:

To change it to something else (You sure you can't handle 24-bit?), you
could get Image Alchemy. Quite a handy tool. I've got a link to it at

Voila!


Also, from the help file/docs:

> Most of these formats output 24 bits per pixel with 8 bits for each of red, green
and blue data. PNG allows you to optionally specify the output bit depth from 5 to 16
bits for each of the red, green, and blue colors, giving from 15 to 48 bits of color
information per pixel. The default output depth for all formats is 8 bits/color (16
million possible colors), but this may be changed for PNG format files by setting
Bits_Per_Color=n or by specifying +FNn, where n is the desired bit depth.
