That should create the correct file. I think there could be a problem with the header that tells the wrong aspect ratio so you should try adding the --aspect|-a option. What is the output of yuvscaler when you start the encoding. You should get something like that: INFO: [yuvscaler] output: frame size: 352x288 pixels (152064 bytes) INFO: [yuvscaler] output: chroma: 4:2:0 JPEG/MPEG-1 (interstitial) INFO: [yuvscaler] output: frame rate: 25/1 fps (~25.000000) INFO: [yuvscaler] output: interlace: none/progressive INFO: [yuvscaler] output: sample aspect ratio: 12:11 That is wrong for PAL, you should have something like 59:54 as sample aspect ratio. When you look at the start of mpeg2enc, check those lines: INFO: [mpeg2enc] Aspect ratio code: 8 = 1:0.9375 (4:3 PAL/SECAM for 720x578/352x288 images) INFO: [mpeg2enc] Frame rate code: 3 = 25.0 (PAL/SECAM VIDEO / converted FILM) What output size do you get when you play back the video with mplayer ? Something like that: Movie-Aspect is 1.33:1 - prescaling to correct movie aspect. VO: [xv] 352x288 => 384x288 Planar YV12 Try a command like that: lav2yuv lalala.avi | yuvscaler -o VCD | mpeg2enc -f 1 -a 2 -o video.m1v That should force a 4:3 aspect ratio, and mpeg2enc ignores the header. > Or please, write me, how can I convert 768x576 pal video to dvd compliant > mpeg2 stream without picture deformatons and (if possible pixels loss) the > same for vcd. If the hints from Steven and me do not help, could you send 1 original frame, and one scaled frame, so we see what happens. 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: YOU BE THE JUDGE.
