Bits Estimation Calculation
Hi I noticed from the MPEG4 ISO specs, the PE calculation is defined as

PE += width * log10(en(B)/thr(B));

Then the estimated bits = 0.3*PE + 6.0*sqrt(PE) for long block..

Why is there a different between PE and estimated bits?

Inoptimal encoding, I guess.

Actually I have reasons to doubt these 2 equations. The final bits estimated is just too low...
