When doing a first pass in MEncoder (to MPEG-2) it produces a log file with information about each frame. I'm wondering what each of the fields in this log represent, and how they correspond to the bitrate distribution of the file produced by the second pass. The fields I'm wondering about (and what my research indicates they mean, in parenthesis) are:
type (1: iframe, 2: pframe, 3: bframe?)
q (?)
itex (intra-texture complexity)
ptex (non-intra-texture complexity)
mv (bits used for MVs (motion vectors?))
misc (?)
fcode (maximum length of MV in log2 scale)
bcode (?)
mc-var (temporal complexity)
var (spatial complexity)
icount (number of intra MBs / number of MBs (macroblocks?))
skipcount (?)
hbits (?)
