I may fall in love with the avidemux encoder if only I could get it to open 
an image.  It wants BMP's or JPG's.

But in looking at the docs for Win 3.5,  it looks like you can only do 
"system specific", which I'm learning is apparently BMP in Win but TGA in 
*nix ???

I really can't find a way to do it right off hand.  How about outputting 
to uncompressed .tga files and using ImageMagic to do a batch conversion 
of the .tga's to .bmp's?

Both formats are an extremely bad choice for a POV-Ray render.  And you 
will hardly find any program un Unix systems that only supports BMP but 
no standard image format.  It is however no problem at all to convert 
the images using Imagemagick convert (you can even pipe the output like 
explained in the docs).

There is not platform specific file format on Unix, the default is PNG 
(which is a good choice for output format in general).

From what I hear, the next version of POV-Ray is supposed to support BMP
output.

And do note that there isa BMP-reading AVI maker written in Java -- which
will run on Linux if you want it to.

From what memory serves me right; this is a good idea -- I've found that the
PNGs that POV-Ray creates are a teency bit smaller than anything I can
create with another program; even by pasting two half renders and
recompressing it.  [Kinda odd, but if it works, go with it anyway.]  You
can use mplayer/mencoder to make AVIs; make sure you have libavcodec and
libpng on your system [devel-packages too !!] and build from source.  Or
use Ubantu, which is _supposed_ to have binary packages; but those don't
run so well anyways [MPlayer actually recommends you to build from source,
and only includes binaries for Windows because 99% of Windows users don't
have compilers whereas Unix users usually have one or another.]

	You must be kidding here, I believe.

Well - the BMP reading/writing code ABX (IIRC) wrote for WinPOV is 
portable so it is not a big problem to use it for a non-system specific 
file format.  The question is of course if this has any advantage (to 
compensate the obvious disadvantages).

In any case I can only repeat: It is a very bad idea (tm) to use BMP as 
a file format with POV-Ray - no matter if for render results or for 
image maps.
