As Syskin says in this post:
http://forum.doom9.org/showthread.ph...827#post305827 changing quant types (in this case to a new quant matrix for the credits) is not MPEG-4 compliant, though it is xvid compliant if on an i-frame. Just a little something to note.
Other than that, it's a really nice comprehensive guide. You also might want to make a quick reference to quantization error (from quantization rounding). It doesn't have much to do with compressibility, but might affect image quality.
Keep up the good work
