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

Description:
This is a HIGH BITRATE matrix designed to work at full anamorphic DVD res (720x432) with bitrates over 1600kbits (for an average motion movie) and works pretty well even with Q2 encodings or extremely High bitrates. But for that target there will be an Ultra-high bitrate matrix (EMQ V3UHR).

EQM V3HR:
Code:
 8 10 10 10 11 11 13 15
10 10 10 10 11 12 14 16
10 10 11 11 13 14 16 18
10 10 11 13 15 17 19 23
11 11 13 15 19 22 26 29
11 12 14 17 22 28 34 41
13 14 16 19 26 34 44 55
15 16 18 23 29 41 55 72

15 15 15 15 16 17 19 22
15 15 15 15 16 18 20 23
15 15 16 17 19 20 23 27
15 15 17 19 22 25 29 33
16 16 19 22 28 32 38 43
17 18 20 25 32 41 50 60
19 20 23 29 38 50 66 81
22 23 27 33 43 60 81 106
Here's the direct link: EQM V3HR

Notes: Unlike V1 and V2, EQM V3 set of matrices were generated using a matrix built starting from a HVS study on luminance by IEEE. The same used by ReferenceDivX to build his HVS matrices.The differences with V2 are minimal (coz V2 is HVS tuned too, but in a different way) but the new coefficient scaling ensures V3 is full IEEE HVS compliant.
The HR matrix is a mid-high/high bitrate matrix.A low, ultra-low and ultra-high bitrate counterparts are coming...
Have fun with it and post your impressions.
Thanx in advance.

WARNING: It may not work with some standalones (expecially the ones with ESS chipsets).

IMPORTANT NOTE:
- FIXED -
There's a recently discovered bug in Xvid that affects all 1.xx versions with Trellis Quantization.
Some matrices trigger an overflow in trellis causing visible blocking at certain quants. One of them is EQM V3HR (but other matrices where reported as well).
There are 2 workarounds (at least i found those 2 only):
disable Trellis Quantization OR limit the MinQ and MaxQ to 2-31 respectively.
- FIXED -

Description:
This is a LOW BITRATE matrix designed to work at full anamorphic DVD res (720x432) with bitrates lower than 1500kbits (for an average motion movie) and works pretty well even with high motion sources (using higher bitrates) keeping details where other matrices produce artifacts.

EQM V3LR:

The LR matrix was created in the same way of HR matrix but tuned for low bitrate encodes.

Description:
This is an ULTRA-LOW BITRATE soft matrix (re)designed for 2 reasons:
- Reducing artifacts as low as possible while keeping a good overall picture quality on low bitrate encodes.
- Producing the best matrix for 1 CD backup.

Description:
This is an ULTRA-HIGH BITRATE matrix designed to work at full anamorphic DVD res (720x432) at very very high bitrates. The saturation point is 30% higher than Didée's 6of9 matrix but at the cost of a lower compressibility.

EQM V3UHR (revision 2):
Code:
8	8	8	8	8	8	10	11
8	8	8	8	8	9	10	12
8	8	8	8	9	10	12	14

Thanks, I'll have to try them next movie I do.
Any comments regarding these matrices versus others?

Sure. All those matrices are HVS tuned, that means they are tuned in some way to spare bits from unvisible details and use them for the visible details.
UHR is a real monster when used at constant Q3 (or for DVD-R size backups) expecially with high quality sources.
For a general use i would reccomend LR or HR.
ULR is not properly an ultra-low bitrate matrix but it's very suitable for full DVD resolution 1CD backups (i dont even take into consideration bitrates lower than 700kbps cause V3 series matrices are aimed for movie backups).
As i said ULR has the same application of Jawor's 1CD matrix.
LR and HR are suitable for 2 or 3 CD backups, you can use them in place of HVS Better/Best or similar matrices.
I'm still testing them on different sources and i need some feedback on compressibility results.
I will do some fine tuning after the test results.

Hi,
Is Ultra High Bitrate matrix suitable for HD content?

It is for sure, but remember that HD content needs more bitrate due to the higher resolution.

Description:
This is an EXTREMELY HIGH BITRATE matrix designed for constant quality encodings ONLY. Compressibility is "ridiculus" in comparison with other high-bitrate matrices but there is a reason...
It's application is pretty obvious: it's for backing up original material or HD material without using lossless codecs.

EQM V3EHR:
Code:
  8   8   9  11  13  13  14  17
  8   8  11  12  13  14  17  18
  9  11  13  13  14  17  17  16
 11  11  13  13  13  17  18  20
 11  13  13  13  16  17  20  24
 13  13  13  16  17  20  24  29
 13  12  13  17  19  23  28  34
 12  13  17  19  23  28  34  41

  8   8   8   8   8   8   8   8
  8   8   8   8   8   8   8   8
  8   8   8   8   8   8   8   8
  8   8   8   8   8   8   8   8
  8   8   8   8   8   8   8   8
  8   8   8   8   8   8   8   8
  8   8   8   8   8   8   8   8

Shartooth: I tested your new EQM V3UHR quantization matrix with two movies (The Bourne Identity and Kill Bill Vol. 2) and the quality I got was simply amazing. Though I had to use bitrates around 3000kbps to get there but it was worth every bit.
Both of the movies were in PAL 720x576 format so I decided to use LanczosResize to resize then to 720x480 so that I wouldn't have to use even higher bitrates (~3000kbps is high enough for me). First pass (Q2) bitrates were around 6500kbps for both of the movies.

Currently I'm making some more tests and comparing EQM V3UHR with Semi-Insane (by the way, SixOfNine didn't have a change against V3UHR).

I've spent a lot of time for "internal" tests and I'm really happy to receive some positive feedback.
There is also an "experimental" version of EQM V3EHR for insanely high bitrates (6000+) or Q2 encodings.
If you have some free time i suggest you to try EHR too.
Have a nice day and thanks again for the feedback.

Thanks, but no thanks... I'm not that insane
I think your EQM V3UHR is good enough for most of us high quality freaks. Not many of us wants to encode xvid clips which are the same size as original dvd...

I managed to do some comparing between V3UHR and Semi-Insane (SI). This time it was really tough to find any real differences between these two matrixes as they produced about equal picture quality. But it seemes that V3UHR handles noisy parts of the movie a little bit better than SI does. With SI when there was panning in the video noise tend to float on the screen a little. With V3UHR I didn't notice this so much. Maybe SI works better on movies that have minimal amount of noise.

UHR should produce a smaller file than semi insane @constant Q2.
Tnx again for your feedback

Hi Sharktooth !
For the last two days I've been testing EQM V3ULR. The original DVD movie 110 min long, with average motion. AR=1.88 (cropping). I decided to make 1 CD bacup using XviD 1.0.2 with 2-pass encoding. Audio vbr mp3 96 kbps. I tried to make a backup without resizing and also did some tests with different resize values (608 and 544). Encoder settings:
QP OFF
GMC OFF
B-VOPs 2/1.5/1
CG ON
MSP 6
CM ON
VHQ 2
MIfi 300
Q I/P/B 2-31
Trellis OFF
The compressibility tests were between 40-68% (depending on the resolution) and they were always about 12% higher than for Jawor's matrix. The problem is that I always got oversized files up to 760 MB. When useing Jawor's matrix, I got proper sizes of files. I don't quite understand what is the reason.

Weird. Have you tried it with different movies?
However try playing with the overflow treatment options.

I've just done 4 encodings for the same movie. I didn't want to use a piece of Vob doing this kind of tests, because I think they are not thruthful enough.

EQM V3EHR is no longer "beta" and matrices for "streaming bitrates" are coming ...

@mateo4x4: Any news?

EDIT: There won't be matrices for streaming bitrates at this time...

Hi !
I had some problems with network connection and I was also quite busy by writting one article. But today I'm going to compress another 2 movies and use EQM V3ULR.
