Wanted: Didée's SixOfNine Max=24 & Max=20 Matrix

[nightrhyme]

I have searched and searched this forum and Google to find these 2 matrices for download without luck.

Would be very grateful if someone could link me to these 2 matices ;)

------------------------Edit-----------------------------
Updated this post with updated links to the two Matrices:

[nightrhyme]

Thanx so much. :)
You made my day :D

[Chainmax]

So, max=24 is 6of9_HVS?

[Teegedeck]

YES, the "max=24" was just because some people seem to have missed the real name!

But beware, the matrix has been updated, and you'll have to correct it manually:

see it here (http://forum.doom9.org/showthread.php?postid=504958#post504958)

[Didée]

Touché.

6of9 -------> 08~20
6of9-HVS --> 10~24

Aaaargh ... seems I'm suffering from the "loosing-race-against-Teegedeck-by-the-second" syndrome ;)

[Teegedeck]

Hehe, the thing you don't know is that mods have the privilege to place their posts ahead in time of any other post they like... :D ;)

[Didée]

The world is mean :D

[Chainmax]

I don't know anything about matrix creation, so I don't understand what "The DC cell of the Inter matrix" means. Could any of you guys post the new configurations for both matrices?

[Teegedeck]

OK, here it is; possible typos included. :p

[attachment deleted; see the reason below]

[Didée]

Veto, Teege .... Inter DC is still at "12" in that package...

[Teegedeck]

AH; I just knew it! I'm not on my encoding PC right now. Wait, I'll just head over to the other room and fix that.

[Teegedeck]

Here is the valid version. I hope; now I'm getting cautious. Could you please check again, Didée? Thanks for being my conscience. ;)

[Didée]

Yep, confirmed. The matrix seems correct.

But these days, better don't count on me acting as conscience ... I'm in too deep trouble with mind and soul. It's not jolly.

[nightrhyme]

Was only the Sixofnine-hvs matrix updated ?
The Sixofnine Max=20 is still valid ?

[Teegedeck]

Yes. And BTW, I also called this one 'valid' because it is no real update but just the SixOfNine-HVS matrix the way it was meant to be. The other version was just a work-around for an ffdshow-bug.

[nightrhyme]

Ok
One more Question because I always get confused.

6of9.HVS is for LOWER BITRATE encodes and 6of9 Max=20 is for HIGHER BITRATE encodes ?
Right ?

//thanx in advance

[Chainmax]

Yea, 6of9_HVS was mentioned as giving a slightly more blurred picture than standard 6of9.

I have a question regarding the quant matrix editor: when I load a .qmatrix and try to save it as .xcm, the resulting file doesn't have an extension. Is that a bug?

[Teegedeck]

LigH would be the person to know about this, as it is his baby. :)
But the extension of custom-matrices doesn't matter actually. XviD config will load just about anything! And I mean it... :p Try it.

[Chainmax]

Ok, I'm going to try loading the .qmatrix files then.

[lordreign]

Please excuse my ignorance for I wasnt into video compression a year ago like I am now but I am just curious as to why it was called 6of9? Any real significance?

Cheers

Maybe Star Trek related?:D

[Didée]

No, not Star Trek related ;)

And I won't kill the fun by just revealing the "secret" - although there could be hint in the thread where the matrix originally was introduced :p ( ;) )

[Soulhunter]

Searched, but without a useful result...

Was it related to its quant scaling or so ???

What's the approximately date of this thread... :confused:


Bye

[Didée]

It was some time ago. (http://forum.doom9.org/showthread.php?s=&threadid=54147&pagenumber=1)

[Surco]

LOL now i understand it :D

Soulhunter, you should improve your searching skills ;) , Didèe, i hope you forgive me for doing this SuperHint (http://forum.doom9.org/showthread.php?s=&threadid=54147&perpage=20&highlight=SixOfNine&pagenumber=2):p

[Soulhunter]

Common, a search (http://forum.doom9.org/search.php?s=&action=showresults&searchid=772063&sortby=lastpost&sortorder=descending) for "SixOfNine" gives nearly 40 results !!!

As you can't sort them by "initially posting date", it wasn't that easy... :o


Bye

[Didée]

Maybe. But "SixOfNine" + "custom matrix" by "Didée" delivers only 3 hits (http://forum.doom9.org/search.php?s=&action=showresults&searchid=772214&sortby=lastpost&sortorder=descending), the right one amongst them ;)

BTW Soulhunter, you know you should never underestimate my little "." dots, yes?
You never know / what's behind ago :D


Okay, and for the rest of the people that might be wondering:

When starting out to design the matrix which finally became SixOfNine, I simply took XviD's standard matrix and multiplied all values with 6/9. The goal was to stay very close to the behaviour of the standard matrix, but to make a wider quantizer range available for bitrate scaling. It ended up a little different - a tad more straightened, a tad more sinusodially. But that was the basic idea, hence the name "Six-of-Nine".

Then, 6of9-HVS was derived from the plain SixOfNine with the aim to give a little lower bitrate again, with comparable visual impression. The HVS derivative cuts a little more into noise, and respects the fact that within a "diagonal line" in the matrix, the center values present higher frequencies than the others, and therefore ~should~/~could~ be quantized higher - whereas most other matrices treat all values in such a diagonal equal. This stronger quantization of central values however isn't constant, but raises along with frequencies growing.
Lastly, the complete weighting of the "HVS" variant was adapted once more, to give a little additional preference to some areas that are important to retain the "sharp" look of subpixel-sharpened sources.

That's all ;)

But I get 11 results... :confused:

Realized this while quoting ya post... :D ;)

Perhaps a new eye-ridle ???
