[M4IF Technotes] Average compression

[Roland Bengtsson]

I wonder how much compression MPEG-4 can achieve. Of course this is a very 
general questions and the compression depends on many things like the 
movie, tha algorithm that is used etc. But I still want to know: I have 
seen a number around 17x compression.
Maybe there is some documentation or paper that I can read further about 
this subject?
Here's my thought of the factors that may affect the compression:
The movie, is it slow or a action movie?
The algorithm for encoding, I would like to hear some numbers about the new 
H.26L/AVC algorithm.
What profile is used, for example how effective is FGS against simple profile?
The cpu-power available, this is of course important. Generally harder 
compression require more MIPS.
The amount of error-correction, have the medium for transport of the movie 
hight biterror rate?
Thoughts please!
