I'm entering my second animation contest ... it's already done. Hurrah!

BUT .... I'm very unhappy with the quality of the final product due to
artifacts in the codec. The other entries I've noticed in previous rounds
always look cleaner than mine!

 I'm using this method:

1] I render to tga format and then use Dave's Targa animator at 24
frames/second.
2] the resulting avi file is then converted into an mpg by avi2mpg

I've tried lots of different frame rates and compression quality settings
but nothing seems to make a crisp mpg file.

Is there a better way? I'm not against spending some $$$ on a good
software package, but I've got to get some advice.

Any help would be appreciated.

Well I've managed to get good results using TMPGenc (http://www.tmpgenc.net/) to
compress straight from the individual frames. The only awkward thing is that you
need to play with the settings to get good results. I find setting it to "2-pass
(vbr)" gets good results, then you can set the target bitrate to balance the
quality against the file size.

My plan is to render the whole animation, then just keep adjusting the
compression quality until I get close to the IRTC size limit!

Hope that helps.

Are you creating a compressed AVI or an uncompressed AVI?  I've gotten
pretty good results going from BMP -> uncompressed AVI -> MPEG.

What appears to work best ...so far .... is to encode the *.avi at 20%
and then  mpg encode at a bitrate of 1200 kbits/sec and vbv  buffer size of
20 and motion search magnitude of 0.


but maybe I should try *.avi at 0%?
anything you might want to know?

thanks

Did that and it doesn't look any different ... come to think of it ...
I tried this for the Jan 2003 round and it didn't look better either.

thanks anyway ... it's off for better or worse!
