That type of artifacting is usually the result of temporal filtering. > > If you attach the camcorder to a TV and view the tape do you see > > trails then?

If you're producing content for viewing on a TV set you really really need to have at a TV set (better yet a production monitor but a regular TV will be better than nothing). The difference between a TV and a computer monitor is substantial. > I compiled the CVS version, but I can't get it to de-interlace my > videos... I think you overlooked 'yuvdeinterlace' ;) My preference is never to deinterlace at encoding time - it's a lossy process that can introduce artifacts. If you really want deinterlacing it usally can be done in the playback software (vlc, mplayer, etc). > nice -19 lav2yuv 200503_Courses_Magny_Cours_01.avi | y4mshift -n -2 | > y4mscaler -I active=744x560+12+8TL -O preset=DVD -S option=sinc:6 | > yuvmedianfilter -T 3 | yuvdenoise -F | mpeg2enc -f 8 -c -D 10 -E -10 -q > 2 -K tmpgenc -o 200503_Courses_Magny_Cours_01.m2v > > Moreover, I can't crop the image as I did in the old 0.6.2 version... =( Sure you can. y4mscaler will crop very nicely. When creating DVDs I use the cropped D1 frame size (704x480) instead of the larger 720x480. How do you get y4mscaler to do that? Easy: y4mscaler -O sar=src -O size=704x480 Can't get much easier than that. Can you? ;) > I would like to keep using a method similar to the one I use for the > moment... Ok - but when you're ready to step up to the next level of quality you're at least aware of the possibilities.
