Hi

Using the method described by Jonny to do a manual compressibility test (2%) with Vdub 1.4.10 and Divx 5.0.1 (b frames only) I get a compressibility test value of 107.3%. Should it be possible to get a value over 100% or am I doing something wrong? My avs file is:

LoadPlugin("mpeg2dec.dll")
mpeg2source("E:\Planet of the Apes.d2v")
crop(2,73,716,428)
BicubicResize(704,288,0,0.5)
SelectRangeEvery(650,13)

and first few lines of 704x288.log are:

##version 2
quality 5
Frame 0: intra 1, quant 2, texture 17434, motion 0, total 17776, complexity 43584
Frame 0: intra 0, quant 2, texture 0, motion 0, total 8, complexity 0

(just to show I cut it right)

Any ideas, thanks.

Andy

I also checked min quant=max quant=2

Hi,

Means your resolution is too low and you will get a filesize below that what you thought you would when you set the bitrate.

Try raising your resolution till the value says around 80% or so...
