I > plugged in a 512 x 384 video, and that's what came out! Thats correct. mpeg2enc never did scale a image. For scaling you have yuvscaler. the format only sets how mpeg2enc encoded the images that are feed into mpeg2enc. > So, for curiousity's sake, what does do? What is a "pre-defined mux format"? That defines the mpeg version, and how mpeg2enc encodes the stream. Some muxformats require special treatment when being multiplexed. And mpeg2enc also takes care of that. You should usually use the same -f option for encoding and multiplexing. auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [EMAIL PROTECTED] www: http://www.lysator.liu.se/~gz/bernhard ------------------------------------------------------- This SF.Net email is sponsored by: SourceForge.net Broadband Sign-up now for SourceForge Broadband and get the fastest 6.0/768 connection for only $19.95/mo for the first 3 months! http://ads.osdn.com/?ad_id=2562&alloc_id=6184&op=click _______________________________________________ Mjpeg-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/mjpeg-users
