Here are the default commands:
mpeg2enc -v 0 -f 8 -I 1 -n p -a 2 -o '/tmp/prova'.mpv
mp2enc -v 0 -r 48000 -b 224 -o '/tmp/prova'.mp2'
mplex -v 0 -f 8 -o '/tmp/prova'.mpeg '/tmp/prova'.mpv '/tmp/prova'.mp2'
I only modify the bitrate (9000k for video, 128k for audio). Also,
kino's options "deinterlace=none" sets -I 1 instead, and usually I don't
deinterlace, so I set -I 0. But this is not the point, the results are
the same.

I can attach a very small picture which shows the problem not for
people, but for the date of the tape which is usually on the bottom
right corner: this picture makes much simpler to explain what I mean.
For the original one at present I cannot provide it anymore, but I will
try with the new tape I'm converting currently.
But the originals never show the snow.
Best regards.
