CompCheck with DivX5.0

[Beave]

Does anybody know about the CompCheck in GK with DivX 5.0?

Do the old values of 45% to 55% still apply? Or should we concider 35% OK now as well, since the codec improves the filesize/quality? I find the CompCheck very usefull to find the best CD number or Resolution.

Or is the CompCheck completely useless now untill a new update arrives?

[Beave]

I just saw, that the DivX4 CompCheck failed in the GK Log. So we probably can't use it anymore with DivX 5.0. Pity.
Any suggestions without uninstalling the codec?

is there anyway to do a compression check manually through vdub?

Remove the # sign in front of the line specifying the decimated frames in your avisynth file. I believe it's at the bottom or somewhete. Then just pass this file to VDub and encode as normal.

[Beave]

You mean, removing the # in front of SelectRangeEvery in the normal movie.avs file? Not the created CompCheck.avs?
And when I do it, what shall I do then? Take the movie.log file and load it in GK? Then it sais "CompCheck failed. Please use the Now Button" usually.

[Acaila]

Yes remove the # in the respective line in the normal movie.avs or however you name it.

What you do then is open VDub and encode it there with all the options/filters you want. I think you'll need 2-pass 1st pass mode for this, so you can input the resulting logfile into GKnot again.

Anyway, this was all just a thought, I've never done it so good luck :)

my compression check works, it doesn't crash vdub or anything.

[BluDChyLD]

i haven't let the compression check run properly with DivX 5, but it starts ok. Can't gknot read the results log properly or something?

[Beave]

What about the Bitrate when I encode it in VD? Does it matter how high it isfor the CompCheck?

[TheWEF]

gknot can not read the new divx5 log-file.
sorry, no divx5 support atm.

patience, please... ;)

possible workaround:

open the logfile with a good text editor like ultraedit.
(ultraedit: say yes when asked if you want to convert to dos-format)
instead of ##version 3
edit: ##version 2
delete the 2(?) lines after quality and before frames that look like

bidirect 0
bidir_mult 2.000000

save the new file and open it with gknot.
or simply do a divx3-compcheck, should be close enough...

A big THANKS to TheWEF for all his hard work!

A stupid question for anyone else is where is the logfile located that theWEF is talking about?

Thx for the reply WEF. Just a few Questions though:
Why can't it be the normal Win XP Editor? I tried it anyway, but got the same answer from Gknot: Compressebility Check failed use the now button.
I think I will do the divx3 Comp Check then. But the "good" Percentage was different, wasn't it? More like 55% to 65%? DivX4 is fine with 45% to 55% I beleive.
I get weird pink artifacts with DivX5 anyways, so I will have to see into that first.

it can, if you like it. :scared:
you just don't see the line-feeds, and files are too big for it very often...

to get a valid comp-check.log that can be loaded into gknot you have to encode @6000kbit or with a fixed quantizer of 2.
before the final error-message you should have got a message like: Average Quant = [something higher than 2].
