cmd:mpeg2enc help

-v|--verbose num

Set verbosity level to num.  0 = warnings and errors only, 1 = informa-
tion as well, 2=really verbose.

-I|--interlace-mode 0|1|2

Set  the  sequence picture structure and block encoding type for MPEG-2
streams.  By default, this value is inferred from the  interlacing  tag
of  the input stream. Setting 0 encodes frame-by-frame with support for
interlaced video turned off, and specifies that progressive chroma sub-
sampling  has  been used.  Setting 1 encodes frame-by-frame with inter-
lace-adapted motion compensation and block encoding, and specifies that
interlaced  chroma  subsampling has been used. Setting 2 encodes inter-
laced material field-by-field, which will produce more accurate results
for  highly  textured  interlaced  material with lots of motion, at the
expense of generally less efficiency.

This setting should  match  the  interlaced-ness  of  the  input
stream,  otherwise  chroma  artifacts  may be generated when the
MPEG stream is played back.

-f|--format 0
        -       Generic MPEG1.
-f|--format 1
        -       Standard VCD.
-f|--format 3
        -       Generic MPEG2.
-f|--format 4
        -       Standard SVCD.
-f|--format 8
        -       DVD MPEG-2 for 'dvdauthor'
-f|--format 9
        -       DVD MPEG-2.

-F|--frame-rate num

Set  the  frame-rate  of  the  output-stream. By default, this value is
inferred from the input header. Currently only the standard MPEG  rates
are  supported.  Eventually more-or-less arbitrary rates will be possi-
ble.
 0 - illegal
 1 - 24000.0/1001.0 (NTSC 3:2 pulldown converted FILM)
 2 - 24.0 (NATIVE FILM)
 3 - 25.0 (PAL/SECAM VIDEO / converted FILM)
 4 - 30000.0/1001.0 (NTSC VIDEO)
 5 - 30.0
 6 - 50.0 (PAL FIELD RATE)
 7 - 60000.0/1001.0 (NTSC FIELD RATE)
 8 - 60.0

-n|--video-norm n|p|s

Force  the  input  stream to be treated as NTSC|PAL|SECAM regardless of
what the stream header might suggest.  Basically  this  just  sets  the
defaults for a bunch of other options.

-a|--aspect num

Set the playback aspect ratio code of the encoded  video.  By  default,
this value is inferred from the input header.
 1 - 1  - 1:1 display
 2 - 2  - 4:3 display
 3 - 3  - 16:9 display
 4 - 4  - 2.21:1 display

For  MPEG-2  the  specified aspect ratios are used directly. For
MPEG-1 mpeg2enc infers the MPEG-1 pixel  aspect  code  from  the
video norm specified and the specified playback aspect ratio.

mencvcd extra:

-s|--sequence-header-every-gop

This flag forces the encoder to generate a  "sequence  header"  at  the
start  of every group-of-pictures.  This is needed by some player hard-
ware to support fast forward/rewind/random access functions  but  is  a
waste of bits otherwise.

mp2enc help

-s     Force  stereo  output.   A  mono input signal is channel doubled
       before encoding to make it stereo.  This is useful for many MPEG
       players which simply can't handle a non-stero signal.
