could need some advice on old movie sources

What is your resolution and bitrate? It is my understanding that too high of a resolution gives macroblocks, while too low of a resolution gives ringing.

Yeah, I'd go for maximum crop res floored to nearest mod16. Meaning you crop all the black bars off (also left/right) and downsize (bicubic/lanczos) to the nearest value dividable by 16. Usually that'll give you 704xsomething, and if you don't need to crop left/right it'll be 720 (no need to resize then). If you still have ringing, at that res it probably won't hurt to use h263 quant.

a always go for 640 res, since i believe it to be enough and also i hava a stondalone mplayer here that outputs to a vga-tv that accepts only 640-res input. no further rescaling involved! ..and who'd encode black bars? ;) unfilter has to be tried now.. throw convolution3d overboard then?

unfilter did it - ringing is nearly gone. thx! i saw myself the convolution3d would simply be too much with unfilter..

well, i'll try out some combinations..nu filter (4 me) - have to get into its pros & cons first..

thx Koepi :) I tried unfilter on some of those old films and it's working well
