Beginners Guide To Ripping With Gordian Knot

I said it's faster. 10-20% faster than MC_Spuds at similar settings. :wink:

I'd be grateful if someone could take a look at this sample and advise me on how best to deal with the blends in it please.

RedVeil

My suggestion would be to use interpolation.

Code:

Interp = nnedi(field=1)
TDeint(order=1,field=1,type=1,edeint=Interp,emask=TMM(order=1,field=1))

junkboy

Thanks RedVeil, I tried that (BFF though) but the best result I've got so far is with this:

Code:

tdeint(mode=1)
c = last.crop(8,16,-8,-8)
Cdeblend(omode=1,dclip=c)
srestore(29.970)
TDecimate(Mode=0,Cycle=15,CycleR=3)

Is that the correct way of doing it though?

RedVeil

Sorry, but you make use of some filters that I never used before. Therefore I can't tell whether it's correct or not. Probably elguaxo can. :wink:

elguaxo

That's a very nasty script

To diagnose the source:

Separatefields()

There are just too many consecutive blended fields -> you can't get rid of them. Maybe FixBlendIVTC? I haven't tried, but I doubt it will help. Whatever you do, motion should remain fluid.

junkboy

Cheers elguaxo, I'll give FixBlendIVTC a try next and see what results I get with it. Just tried finding where I copied that nasty script from, but it looks like I made it up :lol:

Im just in gordian knot basics and i want to try some script for sharpering, looking here and there always found the info so fragmented that is imposible to me give steps forward on it, so i call for help to get the right and working dlls and avs and examples for basic scripting. Is it posible?

elchupacabra

Sharpening scripts (not DLLs) you could try:

- LimitedSharpenFaster
- SeeSaw

Denoising functions:

- MCTemporalDenoise (this is a script -> AVS irc) (nice but slow)
- RemoveGrain (DLL)
- VagueDenoiser (DLL)
- DegrainMedian (DLL)

You should get them and read their help/readme files. Probably you are going to need additional DLLs which they depend on. Just google for it.

RedVeil

I would suggest SeeSaw if you have more noise and need to sharpen a little bit.
SeeSaw is great when your source is good quality and the noise is very low.

Slayer

Mmm, comptest gives me 160% result. I forgot what to do. Any help would be appreciated

And it gets the releases out sooner too

junkboy

I'm not really too sure about the best thing to do (I never seem to get over 100%), but things I can think of are to maybe try a less compressible cqm (Heini_MR or 6of9), reduce the filesize or increase the resolution.

RedVeil

Or switch to H.264 where there are no matrices and the filesize will be just like what you enter. :rock:

they are being used on Blurays/H.264 all the time (for example the "prestige" matrix in the last link). Last year x264 introduced VAQ, PsyRDO and PsyTrellis, so they are not needed as they were some years ago, but there are many H264 matrices out there

Slayer

I'm not switching to h.264, I like to create SA friendly rips.

I'll try a different filter. I want it to be 1/3rd, and increasing the resolution will mean overcropping.

elchupacabra

I would suggest that you make a pre-render pass in this case first. That can save you a lot of time, when playing around with matrices and undersized files and using slow filters.

Slayer

Oh, I said filter but I meant matrix. Well, what's in a name? :wacky:

I'm only doing compchecks now, which is going quite fast, takes about 1-2 mins everytime.

Slayer

OK, with 6of9 and Lanczos resize instead of spline36 I get to 116%. Is this good enough to give it a go, or should I try something else?

Matrices tried (all gave results between 160 and 220%):

eqm_v3hr.xcm
eqm_v3ulr_rev3.xcm
heini_mr.xcm
Jawor_ZSM.xcm
SoulhuntersV8.CQM

When I lower the filesize to 1/6, use 6of9 and spline36 resize, I get a compcheck of 54%. What would you guys do?

elguaxo

I would do a 1/4. If you want to stick to 1/3 lower the amount of B-VOPs to 1 or disable them (aka 0).

elguaxo, if you still have your "insane" profile for XviD could I get that off of you? I know your x264 profile is in the thread but I couldn't find one for XviD. Thanks in advance!

read nr. 12)
http://bad-good.org/phpBB2/viewtopic.ph ... 29#p120429

that profile is for low compressibility. it's easy to tweak for other situations:

low compressibility: leave it as it is
average compressibility: change the Quantization Type from Jawor's 1CD to EQM V3LR
good compressibility: change the Quantization Type to Jawor's ZSM and disable Adpative Quantization
very good compressibility: change the Quantization Type to Heini MR and disable Adpative Quantization
excellent compressibility: change the Quantization Type to Heini MR, disable Adpative Quantization and lower the Nb of B-Frames to 1 or 0

you could tweak many other settings, but I think these suggestions will cover almost everything.
