I try to create an mpeg file from my Hi8 camcorder using S-VHS. My goal is to obtain the best quality.
Here's the command lines I use (I also try to compile mjpegtools CVS to get more options): To rip the stream from my camcorder: nice -n -20 lavrec -f a -i P -l 100 -R m -d 1 -q 80 -b 512 \ record_%02d.avi To encode that file: nice -19 lav2yuv record_01.avi | y4mshift -n -2 | yuvscaler -I \ USE_744x560+12+8 -O DVD -M BICUBIC|yuvdenoise -F |yuvmedianfilter -t 0 \ mpeg2enc -f 8 -c -D 10 -E -10 -q 2 -K tmpgenc -o record_01.m2v Then I obtain a "record_01.m2v" file which contains only video. I extract the audio stream from record_01.avi: lav2wav record_01.m2v | mp2enc -o record_01.mp2 And I try to put the audio and the video stream together: mplex -V -r 1740 record_01.mp2 record_01.m2v -o record_01.mpg Unfortunately, I have some error messages about data which will arrive too late: INFO: [mplex] mplex version 1.6.2 (2.2.3 $Date: 2004/01/13 20:45:26 $) INFO: [mplex] File record_01.mp2 looks like an MPEG Audio stream.
