Beginners Guide To Ripping With Gordian Knot

Do you mean that if you click "First Pass" that dialog won't open? If so, the XviD codec is not installed properly.

It only pops up when you click "Save&Encode" on this screen:

Did you sort it Media Cult?

I need some help.... again. :oops:

With the help of EvilDeadlyImmortality & his native tongue, I've managed to buy a rare Christopher Lee film off ebay France & its a real crappy transfer. Could anyone grab the vobsample & suggest me a script please?

Thanks. :drunk:

elchupacabra

Sure.

Looks quite crappy and very much like RedVeil's "What Waits Below" DVD with a screwed up interlacing.

You could try his script with MRestore posted way above.

BadBugs

Way above is right, dont have a lot of time & gone back 5 pages & not found it.

This ones ''Albino'' http://www.imdb.com/title/tt0074108/

Lets get it as good as we can. :drunk:

I'm trying to do some rippin' but I encountered a problem: my 1/3 DVD rip finished with 1.627.696 KB (1,55 GB). Is it ok? How can I use Gordian Knot to get a truly 1/3 DVD?

If you get an undersize with one, use the next bigger one. If you get an oversize, use the next smaller one.

I remember reading that 6of9 is optimized for min quant 3. Is this true and does it mean it shouldn't be used @ min quant 2?

elguaxo

Yes, it's true and so is Heini 6of9.

Thanks, matey. :beerchug:

I'll post this here, because it is of interest for everybody encoding on a multicore CPU.

Simple/normal encoding procedure on my quadcore CPU:

Result:

Multithreaded encoding using all 4 cores:

Result:

I can't tell the real speedup, because I haven't started the encoding yet. But I can tell you that it is definitely faster. The key is the multithreaded AviSynth version: http://avisynth.org/mediawiki/MT_support_page But you have to be carefull, because some filters crash or producre bad results if you split the frames up. Sometimes even overlapping the frame edges won't help.
Thanks goto elguaxo for pointing me into the right direction. :beerchug:

Almost forgot the AviSynth script:

So now the other PC is quadcore, how do you make virtualdubmod use more than 1 core?

I'm not talking about a GK rip, just a reencode using VDM. :shadey:

@elchup: Hows the filtering guide going? :outsider:

Reencode to XviD? XviD 1.2.x has a codec option (under advanced IIRC) to set the number of encoding threads. It's on 0 (=auto) by default. It doesn't scale well on multiple CPUs as elguaxo said. I think the reason is that the XviD codec is not that much of a load for a CPU. You need to start a lot of threads to reach high CPU usage.

However I don't know how multithreaded encoding is realized with XviD. Whether one thread encodes one frame or whatever.

The real power of multicore encoding is multithreaded AviSynth. If you have really slow filters, MT can save you a lot of time.

I'm not doing any filtering guide. By the time it would be finished, you could already throw it away, because of all the advances. You really have to read a lot of forums to stay up to date. Personally I'm also very busy nowadays. I don't have time for such a project. Moreover it doesn't really look like anybody wants it.

You need avisynth with MT support. Check D9 for the latest version.

You missed what I said after Rogue :wink:

Holy crap!! XviD 1.21 is incredible. Its set at autodect (0) & its reduced a 2.5hr encode in VDM to 45 mins

Thanks for suggesting it elchup :beerchug:

RedVeil

I am in need of some help with a blocky looking rip.
The blockyness is especially visible when the images is moving or dark.
Example (look at the hand on the left):

I wanted to use the Deblock_QED_MT2 script but that results in an AviSynth "Integer Overflow" at line 16:

Code:

block  = clp.mt_LutSpa(false,"x 1 + 8 % 1 < x 8 % 1 < y 1 + 8 % 1 < y 8 % 1 < | | | 255 0 ?",U=3,V=3)

So I tried to old Deblock_QUED_MT2 which uses the "stackhorizontal" and "stackvertical" functions, but the output image in VirtualDub looks exactly like the input images, so I guess it isn't working.

Here's my current avisynth script:

Code:

# Created with notepad

#  PLUGINS
#LoadPlugin("D:\MyProgies\AviSynth2.5\plugins\DGDecode.dll")
LoadPlugin("D:\MyProgies\AviSynth2.5\plugins_extra\mt_maskTools-25.dll")
LoadPlugin("D:\MyProgies\AviSynth2.5\plugins_extra\deblock.dll")
LoadPlugin("D:\MyProgies\AviSynth2.5\plugins_extra\dctfilter.dll")
#LoadPlugin("D:\MyProgies\AviSynth2.5\plugins\RemoveGrain.dll")

#  IMPORT
#Import("D:\MyProgies\AviSynth2.5\includes\LimitedSharpenFaster.avsi")
Import("D:\MyProgies\AviSynth2.5\includes\DeBlock_QED_MT2.avs")

#  SOURCE
AviSource("D:\Temp\the.silencers.avi", false, "RGB24", fourCC="XVID")

#  TRIMMING
Trim(1, 145345)

#  CROPPING
crop(11,2,636,476)

#  RESIZING
Spline36Resize(608, 456)

#  DEBLOCKING
ConvertToYV12()
deblock_qed(quant1=0,quant2=45)
#dfttest(tbsize=3,tosize=1)

# SHARPEN
#LimitedSharpenFaster(smode=4,strength=40,soft=46)

I hope that someone knows a solution for this. :roll:

---------------------------------------------------------------------------------------------
EDIT: After adding ConvertToYV12() before the deblock_qed call everything worked fine.
dfttest does the deblocking not the deblock_qed, I don't no why.

elguaxo

I'm using Deblock_QED_MT2 with great success. But always deblock before resizing or cropping! If you do it after resizing/cropping, you will "destroy" the very sharp edges and alignment of the blocks and Deblock_QED_MT2 won't recognize them as blocks anymore.

Try also bigger values. Some suggestions:

very low
quant1=10
quant2=20

low
quant1=20
quant2=40

medium
quant1=30
quant2=60

high
quant1=40
quant2=80

this is my current Deblock_QED_MT2.avs:
http://omploader.org/vMTUxZw/Deblock_QED_MT2.avs

and remember that you also need Masktools, deblock and dctfilter:
