Auto Gordian Knot: current version 2.55

[Sharktooth]

That's the reason...
Ok, should i tweak it for 1 bframe?

[len0x]

AutoGK uses only 1 bframe, so yes. Does "tweaking" mean that amount of detail should stay the same as it is now, but its gonna be more compressible?

[Sharktooth]

The tweaking consists in balancing Intra-Frame matrix and Inter-Frame matrix coefficients.
The Intra-frame matrix describes the quantization of frequency parameters of blocks from the content of an image or video frame (MPEG I-frames, Intra macro blocks). The Inter-frame matrix describes the quantization of the difference between a reference frame and a predicted frame (motion predicted areas in P and B frames).
So if autogk uses only 1 bframe i can slightly rise the Inter-Frame coefficients gainig some compresibility (without having a huge impact on image quality).
Eventually i can lower the Intra-Frame coefficients to keep the same compressibility and reduce artifacts or gain some details.

V2 - 36,808,704
V3 - 39,133,184
HVSB - 34,459,648

Well, I can confirm your observations. Same results in % @ Q=2 AutoGk defaults 100% Target quality.
By the way: Which target quantizer did you use for your tests?
Or did you use two pass?
This should be taken into consideration for a longer test run.

[Sharktooth]

As i said the reason is AutoGK uses 1 max consecutive B-Frame.
2 pass encoding is aimed for a target bitrate or to hit a specific file size, so, it has to be a fixed quantizer encode (or % quality if you prefer).

[CeeJay.dk]

Why is AutoGK using max 1 B-frame ?
If it's because it originally got better when results with this setting when it was using HVS-B , then there is another option.

Instead of tweaking the matrix to max 1 B-frame , AutoGK could be tuned to 2 B-frames.

Whatever yields the best result overall.

I believed you at first, but then got to thinking and actually tried 2 bframes. Resuts are:

AGK - 36,339,712
V2 - 34,228,224
V3HR - 36,425,728

So still V2 is more compressible ( and I could hardly see any difference between 1 and 2 bframes with the same matrix)

That decision was independent of matrix (and will be as well). There was time when multiple bframes would give you worse quality that single one and support in standalones was not good either. May be its time to re-evaluate that (atm 2 bframes give you about 6-8% in compressibility and I'm unable to see that much difference in quality based encoding, but 2 pass tests have to be done).

Ok, i dont know what's happening then.
I used xvid 1.1, 1 pass constant quant 2 + default settings (no b-vhq/bframes[2/150/100]/Max I-Frame interval 250) + Trellis.
...will try with another source.

EDIT - Same behaviour as my previous Gladiator clip encode. This time it's Spiderman 2 trailer. Same settings as above:
109.215.744 agk.avi
107.216.896 v2.avi
113.881.088 v3.avi

Maybe xvid 1.1 reacts in a completely different way than 1.02 or maybe your source is too small or has too much scene changes (forcing a lot of I-frames insertions)... dunno.
Tomorrow i will revert back to 1.02 and will compare the results.

EDIT 2 - Len0x, have you tried EQM V3ULR in place of Jawor's 1CD matrix?

yes, that could be the reason (I'm using 1.02)

Not yet. What's the compressibility like ?

[Sharktooth]

Installed 1.02... tonigth i'll finish to encode.
V3ULR compressibility is almost the same as Jawor's 1CD.

[rantingotaku]

well, whatever else you changed fixed my problem Len0x :cool: (I'm guessing resizer).

I guess a big "thank you" is in order, even though it's more of an accidental fix :p thanks.

This was no accident - I was not satisfied with Lanczos4 myself.
New matrix is clearly better (and will be even more) and removegrain is a very good filter as well. The only variable that was never tested widely is resizer.

[len0x]

Got report that RemoveGrainSSE2 crashes on it. Anyone has this issue?

I think this is a good decision. Felt not comfortable with the new resizer, even I am a sharp looking guy :D ;)

[CeeJay.dk]

I just remembered since you mentioned a CPU specific part of AutoGK ..
http://allies.freezope.org/ host optimized builds of Xvid 1.02 for Athlon XP and Athlon Thunderbird processors that are faster than the ordinary builds.

I haven't done any proper comparisons but I get really good speeds with this optimized build.

[therealjoeblow]

I tried to reencode the movie I commented about a few replies ago, and put .sharpmatrix into the VIDEO_TS directory with the .vobs, but Autogk's log reads:

[10/27/2004 8:45:11 AM] Compressibility percentage is: 44.28
[10/27/2004 8:45:11 AM] Using softer matrix.

[10/27/2004 8:45:11 AM] Predicted comptest value is: 52.95

It's hard to tell what was actually used because I deleted the other encodes and can't compare. Do you think this just a logging error, or did it for some reason not use the sharp matrix even though I had the control file in place?

Yeah, good builds. Too bad I can't detect processors in the installer of AutoGK - otherwise I could distrubute optimized version automatically.

[Sharktooth]

You can't but the user can... :)

Xvid codec:
|_ Install Xvid x.x (standard)
|_ Install Xvid x.x for AMD Athlon
|_ Install Xvid x.x for AMD Athlon XP with SSE

[len0x]

1) its too much to bundle
2) it might not be as reliable as koepi's (in terms of when they are compiled and continue to be compiled)

[Sharktooth]

Agreed. Also the speed gain is lower than 3%...

[CeeJay.dk]

HKLM\\Hardware\\Description\\System\\CentralProcessor\\0 contain useful keys that will tell what type of CPU processor 0 is ( there are other entries under 1 , 2 , 3 .. depending on how many cpu's are in the system , but they should all be the same )

The optimized codec I use compresses to 206 kb .. probably would be less if it was archived with other builds of Xvid since the files look alike and can thus be compressed to a smaller overall.

But download links to other good builds from AutoGK's download page would also go a long way.

Tks for the link, I tried the xp build.

Done encode on 1 source with hard compressibility to compare. Results are 8% gain for the Xp build on comptest (9.53 to 10.33fps) but marginal on first (33.55 to 33.89) and second pass (24.45 to 24.83). :cool: :rolleyes:

Any news? I tried another sample (Star Wars 2) and again got compressibility that is between V2 and V3HR. This time it was considerably more than V3HR since number of key-framey was 1.7% vs 3.5% that was in my previous test source.

Originally posted by Sharktooth

I found it actually greater than Jawor's. Howerver V3UL seems to resolve more details with no particular difference in blocking (I really need to go back back to my first sample where I can see clear blocking even on high bitrate matrixes @quant=2 - its tough to judge otherwise). having said that more details - doesn't mean better picture on low bitrate matrixes. Removing details and making picture smoother (Jawors) might be better approach since details don't look too good comparing to HR matrixes (but V3UL does try to do that though).

Hello Taurus & Lenox

New to the forum, autogk and encoding I was wondering if the lanczos4/lanczos question applies to my problem ?

Originally posted by Taurus

It seems to me, as if the edges and lines get something overdrawn.
...
But on PC Monitor sometimes it looks a little distorted.


The source is DV cam authored to Pal/dvd, quality not so good. I tried to encode to xvid (messed the sound btw) in AGK 1.70, needed 1/4 dvd for 4.2 Gb.
The result is medium to better but I have distorded lines (jaggies?) in the original and the encode (see pics). I believe it comes from the interlaced material (see log) and tried to change the kerneldeint treshold to 3 or 30 with no improvement.


I have no other clue on the problem and hope you have good suggestions to offer.
Enclosed pictures from the original (mpg2 720w) and the avi (xvid 512w)

Well, in my AGK-HR matrix the more the keyframes the lower will be the compressibility coz the Intra-Frame matrix has lower coefficients than the Inter-Frame matrix. The "key-frame pumping" effect of this kind of matrices ensures a better overall quality (coz I-Frames are reference frames for P-Frames... highering I-Frame quality = boosting overall quality...) but there is a drawback. In a movie that requires a lot of I-Frames the compressibility hit is noticeable.
So i will try to find a good compromise between Intra and Inter-Frame matrices coefficients but it requires some time...
Saturday or sunday it will be ready.

Ok, this is it :rolleyes: Thanks for the quick reply anyway.

When I will have the time I will try to dig, learn, use others progs like avisynth filtering, vdubmod with xvid settings but not at the moment, too much at once.

In this context I will appreciate if/when filtering (whatever the method) become available in AutoGK :D but I can understand that it is not the highest priority at the moment. All my wishes for continuing developping this very good application.

Filename appears correct, and was created before encoding started.

[rmagere]

I think I might have found a bug with the "adjusting the parameters after first pass compressability check".

The bug is that autogk keeps looping, i.e. it predicted compressabilty cA and chose parameters pA after first pass it finds compressability to be cB and therefore decides to do some changes and comes back to choosing parameters pA and so on.

Anyway I have pasted below the log which I am sure is more helpful to you than my description.

The bug is that autogk keeps looping, i.e. it predicted compressabilty cA and chose parameters pA after first pass it finds compressability to be cB and therefore decides to do some changes and comes back to choosing parameters pA and so on.


Yes, it actually uncovered several things:
- there was a bug in comp test recalculations during passes (fixed)
- resolution was not properly raised when comp test result was high (fixed)

Also after reading the code and your log - AutoGK should have adjusted matrix first before trying to adjust resolution. Why that didn't happen - I have no idea, but I would really appreciate you posting the log file from encoding in version 1.53 that I'll put online on Monday (for sure there will be no loops :) )

Actually its a misfeature :) sharp matrix was intended only to work for 1CD or less rips (because it was never used there otherwise). I never extended it for working with any target size. Now I did it finally...

Glad to be of help.

So I should encode the vobs with the same parameters but using v1.53? Ok will do so. By the way if v1.53 is just one of the old version I might have it saved in some dvd so I'll see if I can do the encoding this sunday.

sorry I meant 1.73 :)

[Sharktooth]

@Len0x: Have you tested EQM AGK-HR beta2?
Compressibility should be almost the same as V2 but it needs to be tuned a bit.
Let me know.

[nikolajhendel]

Hi - sorry if this is written somewhere else - but I've been looking half an hour and can't seem to find an answer.

How do I enable removegrain in v 1.72 (or is it just enabled by default) ?

TIA (and thx for a nice easy proggie)
Nick

[Sharktooth]

It's enabled by default.
It replaced the Undot filter.

[Exoskeletor]

len0x in the status bar in version 1,72 you have space after audio ("Audio :").This is different from the codec ("Codec:"). I think that you have to delete the space after audio :) (where are the subtitle options??)

Well, its not. It is slightly more compressible that beta 1 but still nowhere near V2. But the quality is OK - I can hardly see any difference to beta 1: most of the time there is quite a bit of difference in pixels but I wouldn't say which one looks better. On some particular hard frames I can see that beta 1 is sharper and producels less blocks (although the difference is really minor). Overall I'd still choose beta1 considering that most of the time the compressibility difference is less that 1% with beta 2 (but in my high motion sample its actually almost 2%).

Now about Jawor's 1CD vs V3ULR. As I said ealier for me there is quite a bit of difference in compressibility (ULR having 4.5-5% more but trying to resolve more details). So ULR doesn't look that good in terms of blocks on high motion scenes and more details looks rather noisy that sharper I would say. I prefer slightly washed out, but smoothing approach of Jawor's matrix. having said that - I think ULR has a room for improvements: either decrease compressibility to Jawor's level (so that details look better and sharper) or try to smooth picture a bit (I wonder how high compressibility can be achieved then).

[Sharktooth]

Ok, i'm working on your suggestions... :)

Adjustements after first pass should work better now.

I will try v1.73 on the "problem" source, tomorrow morning I will post the log file.

OK, so beta 3 is finally has the same (in fact slightly more) compressibilty than V2, but I failed to the the difference between them :) I looked really hard at difference in pixels and couldn't see the any. I was staring at close up of static person's face for 5 min and in the end I even liked V2 a bit more. So we're back at square one I guess :) (although I really like beta 1, that can be useful if I allow lower compressibility matrix in AutoGK)

Please keep them if possible. I'm evaluating possibility of switching to sharper matrix instead of increasing resolution first. For instance you went from 512 to 592, but instead sharper matrix could be used. Now that I think of it - I switch to softer matrix when width is crossing 512 barrier (608 for widescreen sources) so I should do the same when increasing resolution.

Ok I'll try to keep them for as long as needed or possible.
Should I also keep the various encoding to give feedback on visual quality or is that unnecessary?

By the way the rip is of a japanise anime [in case that might matter].

OK, so beta 3 is finally has the same (in fact slightly more) compressibilty than V2, but I failed to the the difference between them :) I looked really hard at difference in pixels and couldn't see the any. I was staring at close up of static person's face for 5 min and in the end I even liked V2 a bit more. So we're back at square one I guess :) (although I really like beta 1, that can be useful if I allow lower compressibility matrix in AutoGK)
Actually we have 3 choices (beta 2 is not good):
V2 - The actual matrix
beta3 - Should look almost the same as V2 but slightly more compressible (based on V2)
beta1 - Lower compressibility but sharper (based on V3HR)

EDIT: beta 4...

Bug or feature?
After long time using only target quality settings (so without Compressibility Pass), I was trying a custom size encode on a short clip.
What made me wonder, how long it took for the compcheck.
If I remember correctly, former versions of AutoGk used 300/15 as select range, the new release(s)? use 29/15.
Did a short crosscheck with GK compcheck (280/14), much faster on the same source.
Speedwise it is almost a third pass now, and slowing down the encode
significantly.
To lazy to fire up an older AutoGk version, so I don't know how long this is implanted.
If I missed something in the discussion along the way, don't blame me.
I simply don't want to search the whole thread :rolleyes:

Cheers
