ppmtoy4m -h

usage:  ppmtoy4m [options] [ppm-file]

Reads RAW PPM image(s), and produces YUV4MPEG2 stream on stdout.
Converts computer graphics R'G'B' colorspace to digital video Y'CbCr,
 and performs chroma subsampling.

If 'ppm-file' is not specified, reads from stdin.

 options:  (defaults specified in [])
[...]
  -S mode  chroma subsampling mode [420_jpeg]
            '420_jpeg' -> 4:2:0, JPEG/MPEG-1, interstitial siting
            '420_mpeg2' -> 4:2:0, MPEG-2, horizontal cositing
[...]
Is the suggested option right? or it should be  -S 420_mpeg2 instead?
