Annotation of generator/docs/mpegmovies, revision 1.1.1.1

1.1       root        1: Generator outputs AVI files in two formats:
                      2: 
                      3: 1. 24-bit raw uncompressed
                      4: 2. jpeg compressed (so called M-JPEG)
                      5: 
                      6: Quicktime player is probably the best thing at playing these files, I've
                      7: had really poor results from Windows Media Player which usually just tells
                      8: you the file is unsupported.  Great.
                      9: 
                     10: If you are on Windows any avi to mpeg compressor will do the job (I got
                     11: one with my USB video capture jobby).
                     12: 
                     13: On linux you do this, which creates an mpeg with 256kbps sound and 2048kbps
                     14: variable bit-rate (VBR) video:
                     15: 
                     16: 1. install the mjpegtools package
                     17: 2. modify lav2wav.c to remove the bit rate check so that it will let you
                     18:    do 22050 sample rate.
                     19: 3. lav2wav vid.avi >vid.wav
                     20: 4. mp2enc -r 44100 -b 256 -o vid.mp2 <vid.wav
                     21: 5. lav2yuv vid.avi | mpeg2enc -q 6 -r 24 -b 2048 -n n -o vid.m1v
                     22: 6. mplex -V vid.mp2 vid.m1v -o vid.mpg
                     23: 
                     24: You may need to specify '+n' to lav2wav to specify NTSC normalisation, or
                     25: '+p' if you've recorded PAL.
                     26: 
                     27: These are the standard frame rates that mpeg 2 supports:
                     28:   24 (film), 25 (pal), 30 (ntsc), 50 (pal), 60 (ntsc)
                     29: 
                     30: If you try and use something else you may have problems - the mpegtools
                     31: do not support other framerates so you must set the frame skip to 1
                     32: (50/60 fps) or 2 (25/30 fps) in Generator.  If you use another avi to
                     33: mpeg program then it may support a different input to output framerate.
