Hi,

sorry for my bad english.

I have used a BT878 card for capturing from TV and VHS via
composite with a Linux(now 9.0) and mjpegtools 1.6.2-0.
Now, we have DVB-T and i would like to keep this setup for
some time, it works fine.

Since with DVB-T there are still blocking artifacts, i would ask
for the best parameters for mpeg2enc.

/----------------------------------------------------------------
streamer -t $DAUER -i Composite1 -n pal -r 25 -s $AUFLOESUNG -o \
movie.mov -f yv12 -F stereo -O movie.wav -R $AUDIO -w $WARTEZEIT

lavv2yuv $5|yuvdenoise -L110 -C110 -S150 $DNR \
$BORDERSTRING|mpeg2enc $I -a2 -np $ZIEL -F3 -$q -R0 -D10 -N1.0 \
-Khi-res -41 -21 -r32 -c -P -s -b$4 -o movie.m2v 2>&1 | tee \
mpeg2enc.log
\----------------------------------------------------------------

This is for TV/VCR. With DVB-T, there is no noise(?), but blocking
artifacts. My preference is Quality, not size of the mpg-file.

Is yuvdenoise still neccessary? Does anywhone have still ideas
for optimal parameters not boosting up blocking artifacts?

Thanks,
Frank Albrecht(Germany)
