Beginners Guide To Ripping With Gordian Knot

1/1.62/0 is what I recommended to MCMLXXXVIII. His movie is VERY compressible, so 1B-VOP seems more appropriate: viewtopic.php?p=186432#p186432

The difference in compressibility between most of the matrices I listed is aprox. 10%, the difference between 1B-VOP vs 2B-VOPs is aprox 3%. These percentages are true for most movies, but it can change a lot. For a VERY compressible movie the difference between 1B-VOP vs 2B-VOPs can be of 9%.

@MCMLXXXVIII, if you haven't started yet I would not only use 1/1.62/0 and EQM V3HR, but 1/1.62/0 and HEINI_MR. Here is a direct link to this matrix: http://www.mediafire.com/?t9x3z1m0yxy

Tried that last night, it came out at 1.30 GB. Will try upping the filesize unless you have any more suggestions.

next CQM: Didée's 6of9: http://www.fileducky.com/LRMxrEqd/

this is going to be the last one. promise! :wink:

MCMLXXXVIII

Yes, it worked! :devil:

Good job too, I wasn't going to be doing any more attempts at this!

elguaxo, what would you suggest as good settings / matrices generally for 745 MB or 1.45 GB rips?

Ones that have a more predictable compressibility level I mean. :lol:

Thanks for all your help.

I am in need of some help with the rip I am currently doing. The source is an interlaced PAL DVD with much noise.

The problem I am facing is in the deinterlacing step. The frames (half and full) have different ordering in specific parts of the movie.

In one section it is: [FF] HF [FF] HF HF
In another section: [FF] HF HF HF HF

Note: FF stands for full frame, HF for half-frame (this is the interlaced thing).

I tried the following deinterlacing filters with different parameters so far:
- GreedyHMA
- FieldDeinterlace
- Telecide
- KernelDeInt

PROBLEM: The result has some kind of blending. The image is deinterlaced BUT the originally interlaced frames now happen to contain a shifted/blurry part of the previous frame. This also happens when I set blend to "false", which I don't quite understand.

I hope someone can help me. I can post a screenshot if necessary.

post a portion of a vob file. ~20-40MB is fine. You can use DGIndex to cut a small sample:

OK. I hope I did it correctly. Here is the link: http://rapidshare.com/files/120823690/V ... d.m2v.html

Fine! I'll take a look tomorrow. :beerchug:

Thank you in advance!

RedVeil, your sample is very ugly! :lol:

Framrate: motion is fluent at 25fps, so restoring this to another framerate won't help
Combing: use a deinterlacer/bobber at a low treshhold and 'almost' all artifacts are gone. I think I spotted just 2 frames with something similar to combing artifacts after this.
Blending: there are not only blends but I think there is also temporal smearing which can't be repaired.

How do 'unblend' filters work? They work with a bobbed source (double framerate) and try to pick the frames with no blends out of this bobbed source. Now, use a bobber and go to this frame and browse back/forward:

there is no alternative to this frame, even if you try to pick one by hand. This frame is ugly but the other frames nearby are even worse.

This doesn't look so bad, but it's not perfect:

Code:

Import("D:\AviSynth 2.5\plugins\MRestore.avs")

DGDecode_mpeg2source("H:\videos\samples\redveil\VTS_02_1.demuxed.d2v")

TDeint(cthresh=5,AP=0,mode=1)

MRestore(numr=1,denm=2,dclip=last.crop( 14, 4, -14, -4).Spline36Resize(640,480))  ## restoring script

crop( 14, 4, -14, -4)
Spline36Resize(640,480)

Gracias! I will give it a try.
It must be a thousand times better than what I might have come up with. :wink:

I can not see most of the pictures in the guide...?

I'm working on a Beginners Guide to Ripping with MeGUI. I will post it next week and I won't delete the screenshots :lol:

fuEgo

Wow...! Will it include filtering & AVS script modifying?

elguaxo

Yep, that part is more friendly if you start with MeGUI.

fuEgo

Looking forward to it elguaxo. You are the master of encoding! :rock:

elchupacabra

Nice idea. MeGUI is the future, since GordianKnot isn't developed anylonger and it doesn't support x264.

I managed to make a encode of The Oh in Ohio, that wasn't undersized, with the advice from elguaxo to MCMLXXXVIII.

So I also used Didée's 6of9 and got this:

Just think that this movie needs some sharpening... how do I do that?

From my encode:

Some settings:

elguaxo

It looks like SeeSaw candidate. I'll take a look later. :beerchug:

elchupacabra

Hey fuEgo that looks nice. Some sharpening is a good idea imho.

Also make sure you check this post of spud out: viewtopic.php?p=185718#p185718

The lights of the car in your last screenshot look a bit vertically streched to me.
