I don't know what exactly happen but you can use filters (like yuvdenoise and yuvmedianfilter)
Have you tried lowering the quality factor to 4/5. Maybe the -4/-1 otpions help a bit. THe -N (vaules between: 0.7 - 1.0) and -E (-10, 10) and -D (10, -10) options with help much more. > PS: Oh, and is there a better way to convert a mpeg into a yuv stream > than using mplayer? You can use mpeg2dec. auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [EMAIL PROTECTED] www: http://www.lysator.liu.se/~gz/bernhard ------------------------------------------------------- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 _______________________________________________ Mjpeg-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/mjpeg-users
