interesting results
on my own test with old rv9 (non-ehq) i got values ~36.5

edit: i also got pretty low values with wmv9 vcm ~36.8

[karl_lillevold]

Very interesting!

For any PSNR measurements with RV9, please use the following in codecProperties, to disable the noisyEdgeFilter. The filter works like this: in case there are black or noisy pixels along the edge (from a crop that's slightly off, or capture noise), RV9 will copy real image edge pixels to cover these pixels. This is good for visual results, but oftentimes reduces PSNR compared to the original.

<codecProperties type="bag">
...
<noisyEdgeFilter type="bool">false</noisyEdgeFilter>
...
</codecProperties>

[Sagittaire]

@ karl_lillevold

update: all information which you wanted

The RV9 is the best ... ;-)

[temporance]

Great results!!

Watch out though: there is a problem with AviSynth's PSNR measurement as done by Compare(). It measures the PSNR for each individual frame and then calculates the arithmetic mean of the frame PSNRs to get a sequence PSNR.

What, you may say, is the problem with taking an average?

Taking the mean of the PSNR for every frame only ever gives a reliable result when all frames of the sequence are of similar complexity (approx same motion, texture, brightness etc.). If frames differ a lot, then the mean PSNR becomes squewed.

Worse, if a codec has very bad rate control, or something else causes a codec to produce variable quality throughout the sequence, then the mean PSNR as computed by AviSynth's Compare() will actually come out better :eek:.

What's the solution? The best approach is to compute one PSNR for the whole sequence by treating the sequence as if it was one huge video frame. The PSNR is then a function of the total noise energy in the whole sequence and no nasty averaging effects come into play. I tried to modify AviSynth to work like this, but I couldn't get it to compile. So if anyone knows how to make this change...

Should this filter be used for black & white old movies ? And EHQ 80 ?

[Sgt_Strider]

@Sagittaire

I am wondering did you use 2 pass bitrate encoding with Wm9 or 1 pass at 100% quality? How about that slider on image quality? Is it set a 1 space before the first on the left or on default? Can you possibly display the time it took to encode each of those clips with the codecs? Thx

Could you try with trellis and chroma optimisation enabled in the debug tab and with b-frames set to 3/150/75/0 and update your results.

Much appreciated. :)

[CruNcher]

@ Sagittaire
nice compare but your b-frame setting for Koepi was not well chosen 2/150/75/0 would be much better, and also to compare devapi3 vs rv9 is not fair you should better have compared with devapi4 + gmc and trellis quant, 3 warppoint gmc + vhq is working in their now "thx to syskins work" and gives a little psnr boost.

i'll post my new Compare in the XviD forum no rv9 was tested yet :)

[RadicalEd]

make sure you have postprocessing off in the kauehi decoder, last time I checked (which was awhile ago), DXN managed to sneak the post somewhere in vfw decoding >\

The defaut reglage for bframe 1/150/75/0 is very good reglage for the bframe for Koepi 24/06/03 and in conclusion for PSNR ... ;-)

[CruNcher]

@ RadicalEd

pp was off but kauehi simple profile still is better then XviD its true in terms of PSNR or a decoder trick but i doubt that :rolleyes:

[Sigmatador]

i think 1/150/75/0 is good (i prefer 1/150/0/10 :D )

It's a good idea to use trellis for PSNR compare but not chroma optimizer (it might increase video quality but not PSNR ^^ )

A question for PSNR nerd: is there a difference between psnr4avi results and avisynth's compare() ones ?


"3 warppoint gmc + vhq is working in their now "thx to syskins work" and gives a little psnr boost." !!!!!! i want it ^^, going to compile the dev-api4 branch

Thx Sagittaire, but you still haven't answer my question. Did you just two pass bitrate encoding for WM9 or 1 pass VBR?

[Sagittaire]

WMV9
Adjustments: Maximum quality + Complex + 2 pass
PSNR: The WMV9 is really very powerful in this test. It is a codec which "macroblock" practically never and this some is the bitrate.

I believe Kauehi has configurable postprocessing - could be interesting to see if this improves PSNR. Might need to use DirectShowSource() in AviSynth if the VfW decoder doesn't do PP.

[temporance]

An update on AviSynth PSNR averaging: I rewrote part of AviSynth Compare() to create a more reliable sequence PSNR. It's output to the logfile as "Overall PSNR".

I posted my code on the AviSynth development forum here (http://forum.doom9.org/showthread.php?s=&threadid=57744) in the hope that the AviSynth guys like what I've done and incorporate it into their next release.

If you use 2 pass for your encodings, shouldn't you list your bitrate that you use?

Infomrmation in principal thread ........ !?

[temporance]

Is that the bitrate that you set in the codec, or the actual bitrate that the codec decided to produce? Were all the codec's filesizes similar?

WMV9 especially is known to exceed the bitrate that you tell it.

[Sagittaire]

The difference between the file is less 1% for each encoding ...

A variation of 1% for the file by no means variation of 1% on the PSNR ...

I arranged myself so that the variation is favorable to XviD ...:devil:

I did not want to have problem with the fans of XviD ...:D

[Sirber]

XviD fans can be dangerous... :eek: Just kidding :D

lol oops, I miss it :o

[temporance]

@Sagittaire,

I was just trying to replicate some of your results and it seems to me that there are much better settings for at least one of the codecs...

Instead of:DivX Pro Kauehi
Adjustments: Bframe + Slowest + Bitrate Modulation "Slow Movie" + 3 Pass I would recommend:
B frame + slowest + bitrate modulation slider to right (+0.2) + 3 pass + new (slider all the way to right) Psychovisual in passes 2 and 3.

To my eye this gives much better results than your settings (the new PV makes all the difference). PSNR is slightly better, but the video looks much nicer.

[Sagittaire]

the objective in a test PSNR is to obtain the best possible PSNR. But it is true for a better visual quality DivX Labs recommend bframe + Slowest + BM 0.25 + New Psy + 3 Pass. but the PSNR decrease a little.

and really, divx labs recommend "officially" to use bm 0.25 (interesting i always used 0.2 in my tests)?
where did you read that?

[temporance]

I don't think it makes a lot of difference whether you set 0.2 or 0.25. The main thing is to set a positive value.

I found that new PV can actually increase PSNR. So if PSNR's what you want then it's worth a try.

[temporance]

[bond]

Originally posted by temporance
Is that a good thing? I mean, do you still find original 2-pass to be better?? yes, because it shows more details in still scenes and i dont have the time to make three passes (and i think that 2 passes should be enough for a good codec to encode a movie normally)

but why do you think n-th pass is better?

Download and compare ... no comment is necessary ...

The WMV9 clip looks best to me. The RV9 clip looks less detailed... the background appears very washed out.

Update with Manihi Codec: the codec is more better than Kauehi codec. For me Manihi Codec is the best isocompliant-MPEG4 codec now ... sorry for the XviD fan ... ;)

Thanks for the supplying the clips and all your work Sagittaire :)
The Kauehi.rar link doesn't work for me ? Might be a problem my end, but I get a 404 when I click on it.

Update with DivX SBC for the fans: with 570 Kbps and 40% compressibility the encodage with this codec is'nt bad ... DivX SBC is'nt dead with ffvfw ... ;-)

[LordIntruder]

I don't think it makes a lot of difference whether you set 0.2 or 0.25. The main thing is to set a positive value.

You mean you always encode at 0.25 or at least with positive values in the bitrate modulation? I wonder why, this option is here to let the user to force the codec just a bit to increase bitrate in high or slow motion.

If you have a high motion movie it is recommended to use positive values and on the contrary if you have a slow motion movie using negative values.

However the human eye is much more receptive to quality in slow motion as in high motion everything moves so fast you can't perceive a loss in details where you can in scenes that don't move or just a bit.

So it's not easy to determine the better choice to get the better rip except making several full encodes and compare but... Personnaly I chose to support slow motion in most of my encodes movies (usually -0.1) and results are very nice on both slow and high motion.

Great test! Thanks for your work!

info:
altcc-best = "altcc-h-150-100-50"

Does that mean alt.cc with the 'high curve aggression'-setting?

[Animaniac]

I'd like to the same test with 1000 kbps and 1200 kbps bitrates... :o

[Teegedeck]

Where could we download that trailer you used as a source?

[Sagittaire]

It's an trailer of Harry Potter's DVD ... 75 Mo

[Teegedeck]

I just wondered because the highest resolution trailer I've found in the net has a 480x260-resolution. :o Is it a trailer from the DVD?

[Sagittaire]

it's a trailer from HP II DVD 720*576 high quality with no entrelacing ...

[h9903209]

Thx for your testing. Is that possible to include the speed of encoding? How long does each one take to finish the encode?

[Sagittaire]

Update first post ...

XviD devapi4 test
PSNR, SSIM, VQM test and graph
DivX3 SBC ffvfw with Post-Precessing test

RV9 EHQ ... winner

Here my conclusions on these test:

The RV9 is the best codec has weak resolution and weak bitrate far in front of the others.

DivX Manihi and XviD Devapi4 are codecs which are almost equivalent.

WMV9 is the most powerful codec in high resolution and high bitrate.

DivX SBC is still a very good codec and it is still very powerful in encodings with a compressibility superior to 50%.

How about doing some more PSNR tests, using the same 'video only' input file, but this time generating the same output file size.

And all without cropping and resizing?

I think your results will be quite a bit different!

Cheers

@Sagittaire

it's ridicilous, you still do this XviD Ultra High vs DivX Slowest compare thats flawed you need 3x more with Slowest Me in DivX then with Ultra High in XviD, wich is like Standard in DivX and you only win for this 3x slowness 0.1 dB, how you can say this makes DivX the most iso complaint Mpeg4 Codec, sorry can't follow you here. And use compareyv12 instead of converttoyuy2

[Sagittaire]

It's a quality test ... not a speed test ...

But is true the Manihi is slowest than XviD in slow mode but the standard mode is very good too (download DivX5 for demo).

The best codec is not Manihi but RV9 EHQ ...

@Sagittaire

Thanks for the tests. You have obviously spent a great deal of time and effort.

I've been using RV9 for low bitrate anime encoding [3.5hrs into 700megs] ever since I found out it was free. I'm just shocked that it gives higher psnr at higher bitrates too.



@animaniac
I'd like to the same test with 1000 kbps and 1200 kbps bitrates...

You can use linear interpolation for these.[Assumes that the variance of the white noise is constant and normally distributed]

At 1000kbps RV9 and wmv9 should be on par. From the graphs, it looks like WMV9 would dominate at higher bitrates.
