New Quantization Matrices - EQM V3 series (last update: 04/02/2005 - V3ULR) - Page 2

Sharktooth · 13th October 2004, 18:20

Tnx for your effort. I decided to investigate a bit more on the V3ULR matrix. I'm not 100% convinced it's doing good...

13th October 2004, 21:18

Another two movies compressed.
Both long films (118 and 124 mins).
I decided to choose one 4:3 and one 16:9.
This time I did not resize at all.
Average bitrate for video 750 kb/s
XviD settings the same as in my first post.
This time both files got ideal sizes (700 and 701 MB).
So, the reason of previous oversizing is still enigmatic. I'm not sure, but it's quite possible that I've set min. quantisers to 1 for my first encoding. But it shouldn't be the reason. I think I'll try to make same more conversions. I like this kind of matrices, because most often I make 1 CD backup.

The oversize was probably due to the source.
In very particular situations the codec rate control simply fails.
The easiest solutions for ovesized encodings are 2: limit the quantizer to 2-31 or play with overflow treatment settings.
BTW, a new V3ULR is coming. A new softer matrix will completely replace it.
I've noticed too much blocking due to the coefficient distribution.
The new V3ULR won't be HVS tuned but aimed to reduce blocking and artifacts.

EDIT: V3ULR has been just updated.

Grand news for me

Sharktooth · 14th October 2004, 13:51

Just updated.
Dont worry about the compressibility tests... do the whole encode and look at the final quality

new V3ULR - 4 encodings and super results. Really good matrix for 1 CD compression and low bitrate

Sharktooth · 24th October 2004, 13:56

tnx for your feedback! There were 2 versions of V3ULR and i wasnt able to choose which one should be the official ULR. Theoretically speaking the first one should provide a better quality so it was my first choice.
After some negative feedbacks i immediately nuked it coz of the artifacts.
HVS matrices are useless at the lowest bitrates coz there are not enaugh details...
However can you please post your xvid settings and some screenshots of your encodes with V3ULR?

24th October 2004, 14:15

No problem. I've just started another encodig. I tried to reach the compressibility test over 66% and then set all quantizers to 1-3.
I decided to go fishing today so I will try to post all results after I come back from the lake

Is there an error in the forum's database? I can access the "CQM comparison V3" thread through above link. But it doesn't show up for me in the thread list of the XviD forum

You cant see this...

Should I send a pm to a mod or so ???

Bye

Mnl · 24th October 2004, 20:44

I can't see the thread either

unmei · 24th October 2004, 21:00

true, i see thread downto changed 18th oct on the first page - but no "CQM comparison V3" (22th oct) anywhere :/

Teegedeck · 24th October 2004, 21:16

The thread is there; make sure you're not viewing the page from your browser's cache. Click the 'reload'-button. Also make sure you're not using a proxy. Another option may be that one of this site's proxies lags a bit behind. If you don't succeed with the above proposed, I'll pass it on to our tech department.

Soulhunter · 24th October 2004, 21:48

Hmm, is it normal that my thread has no icon @ the left side...

Btw, I cant see it @ my own "Subscribed Threads" page...

Maybe you can see it coz you are a mod or so ???

Or have I enabled the "hide thread" option...

@ All

Sorry for all this off-topic stuff !!!

Bye

Teegedeck · 24th October 2004, 21:55

Uh-oh. There is a problem indeed. I cannot reply in that thread! 'Invalid thread specified'.

Soulhunter · 24th October 2004, 22:02

If you are able to delete it, I could simply re-post it !!!

Bye

Teegedeck · 24th October 2004, 22:05

That doesn't work either. Please be patient until someone more into this PHP stuff than me or Koepi has had a look at it. Thanks.

Edit: Oh, what the heck! Why don't you post it again, now?

Soulhunter · 24th October 2004, 22:26

Is it possible to post a thread with the same title as a "existing" one...

Hmm, I will simply try n' see !!!

EDIT: Yay, seems to work ...

Tia n' Bye

Teegedeck · 24th October 2004, 22:31

Well, it worked.

The other thread will either be eventually deleted or simply wander off into oblivion.
