Hi all,
I got rid of my last issues with the telecine acquisition here. Got pnm
frames, scaled down etc.. filtered, all good. Dv files created, look nice.
And once encoded ... it's terrible.
I am using a straight forward command :
yuvdenoise -F -f | mpeg2enc -f 8 -4 2 -2 1 -r 16 -H -g 6 -G

Hello E.Chalaron,
I've just finished several improvements to the
"near-perfection" scripts I posted a few months

Oh...does kino already support Quicktime? Do we have
