Looks okay, except that I would use -4 2 -2 1 instead of -4 1 -2 1. Also if the original coda.eli is 720x576, you do not need yuvscaler[*] and for the test run you can leave out yuvdenoise -- keep it simple. > then > mplex -f 8 coda.mp2 coda.m2v -o filename.mpg ? Yes. > > Is there any way of checking whether I have got both files in the correct > format before mplexing? Maybe I should build them both again to be sure. The mplex output contains a number of parameters that you can check -- frame size (720x576), fps (25), number of video pictures (fps x length of the video in seconds), audio sampling frequency and mode (48000 Hz, stereo), audio bitrate (224000/8 = 28600bytes/sec) audio stream length (approx. = bitrate in bytes x length in seconds), average and peak bitrates of the mplexed stream (should be less than 10.08 Mbps). Finally make sure mplex completes without any errors, especially buffer under-runs. The o/p you posted in the morning looked fine in all these respects. Selva [*] The last time I used yuvscaler it did not support -O DVD, but I haven't touched it after y4mscaler appeared. Make sure it generates 720x576 frames for PAL. ------------------------------------------------------- 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
