[MPlayer-users] Bits per pixel

Please read 
DOCS/en/menc-feat-dvd-mpeg4.html#menc-feat-dvd-mpeg4-resolution-bitrate-compute
There you'll find formual for ResY, where CQ parameter is present. 
It represents the number of bits per pixel and per frame of the 
encode. So, you can calculate it 8-).

Notice: IMO 0.249 is too high even for archive purposes encoding, 
modern codecs allow lower values (just read the article, mentioned 
above).
