I am using Miro DC10plus so I capturing video with 768x576, PAL, 25 fps. Excuse me, I wrote all data about my sorce in the first post. The question is... I am shooting videos nearly every day with my vhs-c camcorder, and then transfer data to pc with 5000 mb/s bitrate (768x576) When I create vcd or dvd mpeg stream I have a little deformed video in the output, because I have in the source square pixel (3:4 or 768x576 but then converted it to dvd 720x576 or vcd 352x288 that is not 1:1 aspect ratio) For example, when I create vcd, a make: lav2yuv lalala.avi | yuvscaler -o VCD | mpeg2enc -s -r 16 -o video.mpg So I recieve 352x288 and picture apeears deformed because it can't be deformed with 384x288. So, when I am making high resolution mpegs, I do: lav2yuv lalala.avi | yuvdenoise -F | mpeg2enc --no-constraints -f 3 -q 2 -b 5000 -o video.mpg I can view mpegs created like this on my computer with mplaeyr and I even give them to my friend who can view files with PowerDVD player. And I am happy that I have picture very similiar to the source video. Why I am using mpeg2enc? Because it keeps colors the same as in the source video! It is the only one encoder I ever seen that don't spoil colors! So, I don't want deformed picture too. But what if I want to write DVD some day? I wrote that I remember a faeture in TMPEGEnc that adds two black strips on top and bottom of the screen and keeps original aspect ratio this way. You told me I don't need black strips - that's cool! And I have to use yuv4mscaler. > > example, try "y4mscaler -O preset=vcd" and follow the suggestions.) yes, I have tryed y5mscaler -O preset=dvd but then mpeg2enc tells that can't handle interlaced video... > > hint: try adding "-i ilace=TOP_ONLY" to y4mscaler's options. I did it... but unseccesfully... Becasue of that I making now: lav2yuv lalala.avi | yuvdenoise - F | y4mscaler -I sar=1:1 -O sar=PAL -O size=352x288 -S option=sinc:4 | mpeg2enc -s -r 16 -o video.mpg or lav2yuv lalala.avi | yuvdenoise -F | y4mscaler -I sar=1:1 -O size=720x576 -S option=sinc:4 | mpeg2enc -f 3 -q 2 -b 9000 -o video.mpg And this is awfully slow way. That's a reason I asked You how deinterlace video with y4mscaler 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.
