Compressibility check problems

[curna]

Hi.

I'm trying to do a compressibility check using Virtualdubmod, Avisynth 2.5 alpha and GKnot 0.27.

I've already renamed Virtualdubmod to Virtualdub, but I still have problems.

When I try to run the compressibility check, Virtualdubmod crashes. Here is my log:

So, I tried to do it manually. I opened Vitualdubmod and I loaded "LastCompCheck.avs". I've configured the compression options to do a first pass with divx pro 5.02 and keep the log file.

In that case Virtualdubmod does the encoding. However, when I try to load the "log" file to GKnot 0.27, I get the following message:

"number of pixels per frame is not stored in a divx4 log file. The only save way to do a compressibility check is to use the "now" button in the "save avs" dialog."

My log file has this look:


##version 4
quality 5
bidirect 1
bidir_mult 2.000000
Frame 0: intra 1, quant 4, texture 14530, motion 0, total 14880, complexity 181625
Frame 0: intra 0, quant 4, texture 0, motion 0, total 8, complexity 0
Frame 1: intra 0, quant 4, texture 0, motion 0, total 728, complexity 0
Frame 2: intra 2, quant 4, texture 0, motion 0, total 67, complexity 0
Frame 3: intra 0, quant 4, texture 0, motion 0, total 728, complexity 0
Frame 4: intra 2, quant 4, texture 0, motion 0, total 67, complexity 0




What am I doing wrong ?? Any hint to be able to make a compressibility test ???

Thanks for any help

Hi-

According to this Thread (http://forum.doom9.org/showthread.php?s=&threadid=42150), you can't use VDubMod for encoding from within GKnot yet. Maybe soon?

[curna]

Well, finally I think I managed to do it.

What I've seen is that the problem is with the name of the log. If the file has the name "divx.log" I cannot load it into GKnot, but if I put a name like "_4_perc_D5_Bilinear_480x352.log"(The nameGKnot will use by default), then I can load it.

[jonny]

The only requirement is that you put "_480x352.log" at the end of the file (i've made my tests long time ago :))
You can also try DivX5Enc, no problems with VDubMod

Thanks, I will try it.

Well, and thanks again :D .

Just to short questions:

1- Then putting in the name "bilinear", "bicubic"... doesn't change in anyway the results.

2- When doing the compressibility test, do I have to change the quantizers ??? Will they affect the result of the compressibility check ?? When I encode I use a minimum quantizer of 2 and a maximum of 9, but I think that GKnot uses quantizers of 2(min) and 2(max) for the test. I think that's to know what's the maximum quality compression, bt I'm not sure.

Yes

GKnot use bitrate=10000 & minquant=maxquant=2 (i think), anyway the idea is to maximize the size in comptest, so, if you run the first pass manually for comptest, the safest way is to set 10000, 2, 2.

[curna]

Thank you very much for the answer. You were very helpful.

You can still load a logfile named eg divx.log, you just select yes from that warning message. The thing is if you adjust the resolution and load it again it will load the same value as before. I just realised from what jonny said about adding the resolution to the name of the log that this will make gknot adjust this value taking into account the resolution used in the compt test and the current resolution in gknot.
