[MEncoder-users] change bpp

[Aleksandar Uzelac]

  for some time now i'm trying to change color depth of mpeg2 video while converting it to xvid. mencoder creates xvid file with 12bpp, but if i try to convert same mpeg2 video to divx (with lavc) mencoder creates divx with 24bpp (and the difference is significant).

  how do i change pixel color depth (bpp, biBitCount)?

  configuration info:

MPlayer 1.0pre6-3.2.3

divx:
