> I meant 640x480 not 540. Anyway, anyone with some help?
I render at 320x240 (or whatever my final animation size will be).
I also render for 24 frames per second (-f2).
The d and m options I usually leave at -d0 and -m0 (the defaults),
especially for test renders. For my current entry I used -d1 and -m1,
which vastly increased the time it took to compose the MPG, but
reduced the file size by 10%.
For the compression specs, I usually use the ipb.ctl file, although
I have tweaked it slightly. The forward and backward vectors for P
and B frames are set to one in the original; I set them to two or
three. The default also has quality settings of 4 for the I and P
frames, and 8 for the B frames; I usally pare this down to 3 and 6,
for improved quality.
CMPEG's algorithm could stand a lot of improvement, and as it's
written to run on a 286, updating it to use 486 instructions would
probably yield a significant speed boost as well.
Regards,
John
