I just found a Mpeg2 encoder that will handle .ppm image files. There seems
to be two versions available one for dos and a win32s executable. If anyone
is interested take a look at the following site:

The *.tar.gz file was not downloadable, for me anyway, but the FAQ sheet
there was well worth a look.

Oh well back to the drawing board as they say. I didn't check the
secondary link there presuming they had it archived on site. I will
continue my search though so stay tuned...

Try this and see if you can get it to work. I don't have any animation
projects in the works to test it on or time to do it:

Got the files this time, just now tried it out and didn't get any output
done right. It seems similar to CMpeg in the way it's run on the DOS
command-line but it just wouldn't do as expected. Need more time with it to
figure it out I guess.
Thanks for that "other" URL.

I've been trying to put something together with it myself and it just hangs at
the command prompt. I even left it to run all night and when I came back it was
still stuck. I don't know if it's a problem with the ppm files I was using.
It's says it can only use raw ppm files, but I have no idea what that means.
The source code is included so maybe I can figure something out that way.

Did you guys get anywhere with this?
Recently i've acquired a bunch of MPEG-2 hardware. So i've thought about rerunning
my anim ( http://www.buckosoft.com/gallery/raytrace/tteoac/ )
through MPEG-2; 720x480 looks very cool (well 4x as cool as 320x240).
I mentioned this on the irtc-anim list and Ralph Giles turned me on to that encoder.
I haven't had a chance to play with it yet, but i expect that i will soon.
One thing is i like to render my frames to png so i can use ACDsee thumbnail to
preview
the 3000 frames, so i would like to try dropping png support into it. If there are
basic flaws that you've already fixed, that would help me a lot.
+++
I was surprised that 720x480 is "broadcast quality", i would have thought that to be
low.
It was interesting to learn that VHS tape is lower resolution than that.
Now i get paid to watch Antz all day [1] and i am amazed how good 720x480 looks on a
20"
inch TV (via DVD). I'm used to 1600x1200 on a 21" monitor for stills.
One thing about Antz (on DVD) that is cool, are two chapters on animation techniques.
Must see TV for us animators.
Time to fire up the ol' renderfarm...
( http://www.buckosoft.com/bsac/ )
[1] Actually i get paid to manipulate the bitstream that was and will be Antz. Most
of
the time the monitor is off, put the DVD on "repeat" and just tweak the bits.
(Most of the other guys in the office watch The Matrix.)

I've seen that too. I've also seen that the blocks are divisible by "16 or 32".
486/32=15.1875 or 30.375
mpeg2enc.c:85
/* round picture dimensions to nearest multiple of 16 or 32 */
mb_width = (horizontal_size+15)/16;
mb_height = prog_seq ? (vertical_size+15)/16 : 2*((vertical_size+31)/32);
Of course, these are NTSC numbers. Our PAL buddies get better resolution.

So NTSC is 720x480ish. What is PAL?
