It seems that with the right set of options, and the right set of
input data, -Q can help to create some really nasty looking
artifacts.

Has anyone noticed mpeg2enc rc92 creating odd "flashing" artifacts on
what should be otherwise generally smooth color backgrounds? I've
attached a small jpeg (29k) showing an example of the artifact. If
you look to the right of the tall actor's shoulder, you can see very
clearly what I'm talking

e editing to include mpeg2enc libs on the
final mpeg2enc link call. It wasn't hard to do, but it did take a
bit of investigating to determine which libs should link in.

I've got a second real world example now:
76,643 MJPEG frames, for 42.6220 minutes of video.
GOP 54 343,248,122 bytes
GOP 18 357,706,821 bytes
A 4.042% reduction in size.

Has anyone tried the current cvs mpeg2enc lately? I pulled the
current cvs on Nov. 4 because I wanted to see for myself how well the
new "no B frames please" option worked. But my copy of mpeg2enc
compiled from the source I pulled that day takes a segfault while
it's processing the first frame (
Does anyone on the list have one of the latest and greatest AMD
Athlon 64's? If so, how does it stack up speed wise running mpeg2enc
vs. Intel's P4 chips?

For a while it has seemed to me that negative width and height values
given to yuvdenoise on the -b parameter have not in fact created a
black border on the bottom and/or right of a filtered image. So I
started looking around in the code to see what was up.
The man page says that the -b paramete

Attached is a small patch that I put together today that based on my
measurements produces about a 6-7% speedup of yuvdenoise if the
luminance contrast option is used. I got the idea for the change
from the yuvcorrect sources, the optimization is to pre-compute the
contrasted values for pixel val
