and thanks for all previous suggestions. Today I had time to test some
changes. Seems to work better.
Because the administrator of this list kicked this mail _with_ attachments, I
send it again _without_ attachments (images). The images will be available on
my server for next two days and then be deleted automatically. So, please have
a view on them before Saturday.

I understand. I chose vbitrate now. Hope that avidemux is still able to cut

I switched now to pp=fd. Seems this changed the quality most. But I had to
remove the aspect=4/3. When I use it, I loose the properties of the image.
Now I will play around a bit with denoise3d options. I used 8:6:6, you
Actually, I do not understand what it does. Can you explain, please?
What I actually want is to loone not too much "sharpness" of the image. If
denoise3d works as a "soft-filter", it should be used minimally.
I attached four images out from a recorded TV snipped: test1.jpg ... test4.jpg
and tried to keep them as small as possible (=jpg).
As you can see, test1.jpg now has no varying red/orange horizontal bars any
more .. it actually flips between red and orange from frame to frame... ?! But
it looks still better.
But watch test2/3/4.jpg. This are three frames, in this order, following each
other. Watch the colors of the childrens dressings and the inserted text.
test2.jpg ... All colors with shades of red look a little bit more orange
test3.jpg ... Now the colors are more red, actually this will be closer to
test4.jpg ... Now every orange and red is more to yellow again...
Also watch this black noise in the text, as well as the dark dashes in
test1.jpg. Is this coming from the movie or from mencoder?
