I've encoded several things since successfully compiling from CVS last week and it seems to me
the quality has noticeably improved. I originally built from CVS wanting to try y4mdenoise, but
it is just too slow for me to use. However I do use y4mspatialfilter right before yuvdenoise, so
my chain is {raw video} -> yuvscaler -> yuvcorrect -> y4mspatialfilter -> yuvycsnoise
-> yuvdenoise -> mpeg2enc. ..short chain :-)
Anyway, it appears to me the quality is a little better than before (ie - last
official release). Edges seem to be very crisp now. I'm not sure if that is
from improvements in yuvdenoise, the addition of y4mspatialfilter, improvements
to mpeg2enc, or some combination :-) y4mspatialfilter's defaults caused the
image to blur really bad, but I was able to tweak the parameters to it to get
some good results. I get a slightly lower bitrate using y4mspatialfilter, but
keep it before yuvdenoise because if I place it after yuvdenoise it tends to
blur a little. Seems like yuvdenoise runs faster than it used to as well,
though I've not done any specific timing from old to new.
