Gordian Knot very very slow! Why?

[EmreBelozoglu]

Hi.
I'm an italian user. Excuse for my english.

I use Gordian Knot to backup (with DivX 5.02 codec) my DVD

This is the procedure to create a backup copy of my dvd:

1. Ripping
2. *.d2v file creation with DVD2AVI
3. Set the parameters of output video (resolution; cd number; etc.) in the Bitrate Tab and in the Resolution Tab.
4. I select Save&Encode in the preview window of .d2v file.
5. I set the parameters in this window
6. I click on Save&Encode button

After this step the process becomes very slow.

After about 3 minutes VirtualDubMod started and it processes the video at very low fps: 12.0 or lower.

I installed this files:
GordianKnot.RipPack.0.28..3.Setup.exe
GordianKnot.RipPack.0.28.4.Beta.Update.Setup.exe
GordianKnot.CodecPack.1.2.exe

Why the compression job is very (very very very...) slow?

Using FlaskMPEG the fps are about 25!

This is my hardware:
CPU AMD Athlon 1400+
RAM 512Mb
HD 40Gb
Video Card TNT 32Mb
Audio Card Creative Live 5.1
DVD Reader LG 16x/48x
Yamaha CD Writer 20x/10x/40x
Pinnacle Studio Deluxe
Monitor 19" LG
Scanner Nortek A4
Laser Printer Samsung ML1210

System is: win2k pro

Thanks!

there must be something different with your settings, more then twice faster is to much

[jggimi]

If you select noise reduction filters, your encodings will s l o w w a y d o w n .

Can you post your .avs script and your _Gknot.log?

There is a simple way that i solved it

go to virtualdub mod and go to the preferences menu there u get options like default process priority etc

dont worry about that the only one u need is make sure it is set to fast recompress rather than full processing

then on the next page enable 16 bit dithering and disable view input output windows as these slows things down

hope this helps

You can see that encoding time is about 40 minutes.
Gordian is very slow.

I will try with jeremymacmull settings.

Thanks!

[EmreBelozoglu]

I have tested the settings that jeremy suggests,
but the encoding time is not improved.

Help me!!

[Acaila]

Could you please edit your avs script in your previous posts and delete all lines that start with a # those are comments and as such don't provide any information and only make this thread difficult to read.
For instance, if you had done that right away we could have easily seen that all you changed between your first and second attempt earlier was using Lanczos instead of Bilinear resizing, adding a comment like "the speed didn't increase when I changed my resizing filter" would have been enough. Don't post logs/scripts unless they add information to the discussion.

I noticed in your last script that you used the following:
LanczosResize(512,282)
Although DivX claims that it supports modulo 2 resolutions, it is a very bad idea to actually use them. Artifacts have been known to appear when people did this. It's best to stick to mod 16 resolutions instead (which btw is the default in GKnot, as you understand it's there for a reason).

This might even be a reason why your encodes are so slow because certain resolutions allow both the codec and avisynth to use specific MMX/SSE/SSE2 algorithms that can speed up enoding significantly.

[bira]

I am getting around 19fps. (first pass)

- avisynth 2.5
- mpegdec3.dll
- 720xsomething 2:35 or 16:9 ratio.
- lanczos resize
- no other filters

I am using a 2GHz P4. Is that ok?

In time, DIVX 5.05 is definetly slower then its predecessor since it does not use .mv files anymore, right?

I use modulo 16 resolutions, but the results not change.

gordianknot is just a gui for creating a avisycript (ok a little bit more), but encoding is still done by the codec ;)

so if you have half the encoding speed you cant blame gknot, i am sure that it is caused by different (better) codec settings than in flask which cause the speed drop

ps: i have a p3 866 and i encode at ~5 fps with all xvid settings necessary to reach the imho best results (i dont care about time)
pps: use divx505, it is much better than divx502!

@EmreBelozoglu

ive got a p3 850 and i get between 10-12 fps depending on settings etc and b frames

If you use lanczos filters and the denoising and deinterlacing and bframes gmc etc it becomes a lot slower

try unistalling everything ESPECIALLY avisynth and reinstalling .28.3 beta then .28.4 beta and try again plus ive got a pentium pc so i know vdub is optimised for pentiums i dont know what kinda of speeds AMDs get!! anyone!????

For that respect this gordian knot is way quicker than its former version (due to avisynth 2.5x)


LAST but not least FLASK uses i think Divx 3.11 Which is a LOT faster than the 5.02 or 5.05 codecs are u sure you are encoding in flask with 5.02 ??
Divx 5.05 IS a lot slower than 5.02 especially second pass but in my opinion the quality is worth it

Just a thought

don't forget about frameserving, decoding etc.

who told you this :confused:

although i would say that frameserving is done by avisynth and decoding is done by mpeg2dec3...

I said don't forget about the frameserving not because you said Gordian Knot is a little bit more than a AviSynth GUI, I said this because you said the encoding is done by the codec but didn't mention there a other things like frameserving that take CPU time which make VDMod slower than Flask.

I've only ever gotten ~10-12fps with gknot encoding to divx5 versions with interlacing, bframes etc on my AMD Athlon 1GHz 640MB RAM machine so I do't believe you are going particularly slowly at all.

I do remember that when I used flask a few years ago that the speed was faster than this, however the quality just didn't come close to what I'm getting now.

just be patient :D

I noticed in your last script that you used the following:
LanczosResize(512,282)
Although DivX claims that it supports modulo 2 resolutions, it is a very bad idea to actually use them. Artifacts have been known to appear when people did this. It's best to stick to mod 16 resolutions instead (which btw is the default in GKnot, as you understand it's there for a reason).

This might even be a reason why your encodes are so slow because certain resolutions allow both the codec and avisynth to use specific MMX/SSE/SSE2 algorithms that can speed up enoding significantly.

Acaila, Can you eloborate on what resize filter to use? Please recommend one from the choices in GK.

Thanks,

Hi-

He's not talking about the resize filter itself. LanczosResize is fine. He's talking about the resolution. Your 512x282 is at fault. The 282 is only mod 2 (only divisible by 2). It should be either 512x272 or 512x288. Reset the H-Modul in GKnot to 16. For more information, please read this Sticky (http://forum.doom9.org/showthread.php?s=&threadid=42708).
