[20-06-2005] Metric Benchmark Challenge ...
~ Movie Metric Benchmark Challenge ~
You think that your codec is the best : prove that ... !!? A - Introduction The purpose of this challenge is to determine which is the best codec for the metrics and only for the metrics : this test will not speak about subjective visual quality. If you want subjective visual comparison download sample and compare yourself ... B - Rules Rule 1 : Source You must use this source for the test : Harry Potter II trailer, 720*576 MPEG2 MP@ML 4.5 Mbps HPII Part1 winrar, HPII Part2 winrar, HPII Part3 winrar, HPII Part4 winrar & HPII Part5 winrar Rule 2 : Pre-process and encoding You must use DGindex with 32-bit SSE/MMX iDCT algorithm for .d2v project and DGDecode.dll for MPEG2 decoding in avisynth scipt. You must use VirtualDub or VirtualDubMod in "fast compress" mod for VFW codec. You must use YV12 space color for complete process with all codec. You must use this avisynth script for make encoding: Code:
source=Mpeg2Source("C:\...\HPII.d2v",idct=2) source=Trim(source,70,3145) source=Crop(source,0,76,-0,-76) source=LanczosResize(source,720,304) Return(source) Rule 3 : Bitrate You must use 2 bitrates for encoding. The first use XviD in quant8 for reference, it's the "Streaming Quality". The second use XviD in quant4 for reference, it's the "1CDR Quality". You can use container of your choice for all Video Elementary Stream. Streaming: 450 Kbps for Video Elementary Stream and container or 6750 Ko with +/- 0.30 % for tolerance. The size must be in [6730 Ko - 6770 Ko] interval. 1CDR: 900 Kbps for Video Elementary Stream and container or 13500 Ko with +/- 0.30 % for tolerance. The size must be in [13460 Ko - 13540 Ko] interval. Rule 4 : Metric Tests SSIM (YV12): IMO the best metric. it uses some HVS properties but not all ... PDF description for VSSIM Overall PSNR (YV12): Very good metric test, particullary for Rate Control Quality test ... MSE = Sum t = 1 -> NFrame Sum x = 1 -> width Sum y = 1 -> height (F'(x,y,t)-F(x,y,t))² / (NFrame*width*height) Overall PSNR = 10 * Log ( 255² / MSE) Average PSNR (YV12):The worse metric test but Frame PSNR graph is very good to compare RC strategy ... MSE = Sum x = 1 -> width Sum y = 1 -> height (F'(x,y,t)-F(x,y,t))² / (width*height) Average PSNR = Sum t = 1 -> NFrame 10 * Log ( 255² / MSE) / Nframe Here the test archives if you want all original Avisynth script for metric test. SSIM vs PSNR "For a given reference video and a given compressed video, it is meant to compute a quality metric, based on perceived visual distortion. Unlike the well-known PSNR measure, it's not purely mathematical, and should correlate much better with human vision." "A higher MSE (and so lower PSNR) should mean that the compressed clip is a worse image but MSE and PSNR are flawed in this respect as numerous tests have shown. However with SSIM, according to tests carried out on the VQEG dataset, a higher Q (SSIM value) has a much better relation to the visual quality of the compressed clip. Despite this, bear in mind the SSIM metric still isn't perfect." Here last AviSynth plugin for VSSIM in YV12 Average PSNR vs Overall PSNR It's easy to increase artificially Average PSNR with Rate Control tweak. In certain case CBR (0% for variability) will be better than real VBR (100% for variability or constant quant). It's generaly not possible with Overall PSNR. Overall PSNR is very good to test Rate Control quality. If difference between Average PSNR and Overall PSNR is very high, "local quality difference" (difference between Pframe or Bframe for exemple) or "scene quality difference" (difference between low motion and high motion for exemple) will be too high and Rate Control for this codec not very good. Here last AviSynth plugin for Overall PSNR in YV12 You must mux or remux x264, VP6, VP7, WMV9, DivX6 and XviD in avi container (with VDM for example) to solve problem with color space output, synchronisation or acquisition for metric test. You must use AviSource in avisynth for VP6, VP7 and WMV9. You must use DirectShowSource in avisynth for MPEG4 ASP, MPEG4 AVC and RV10. You must change trim for frame synchronization or for clip length if you have some probleme with SSIM plugin. You must use these AviSynth type script for metric test: Code:
# --> Source Opening <-- source=Mpeg2Source("G:\...\HPII.d2v",idct=2) source=Trim(source,70,3145) source=Crop(source,0,76,-0,-76) source=LanczosResize(source,720,304) # --> Video Opening <-- video=DirectShowSource("G:\...\DivX6-450.avi",fps=25) # --> PSNR analysis <-- compareYV12(video,source,"YUV","PSNR-DivX6-450.log") Code:

Conclusion At this time for this trailer MPEG4 AVC codecs: NDAVC vs x264 Ateme H264 and x264 are comparable codec for OPSNR but not for SSIM (visually NDAVC is IMO better than x264 too). x264 is the best Open Source Codec and XviD can't fight with the last version. MPEG4 ASP codecs: XviD vs DivX vs LAVC DivX6 is the best MPEG4 ASP codec for OPSNR and SSIM but XviD, DivX6 and Libavcodec ASP are very close codec. Proprietary "free" codecs: RV10 vs VP6 vs WMV9 VP6 is always better than RV10 or WMV9 for OPSNR or SSIM. VP6 are better than all MPEG4 ASP codec for OPSNR and SSIM. RV10 is an excellent codec for high quant encoding (low quality or "low bitrate"). Higest performance codecs: VP7 vs NDAVC vs x264 VP7, Ateme AVC or x264 are really better than the others codecs. VP7 seem better than Ateme H264 Main Profil for very high quant (low quality or "low bitrate") and Ateme H264 Main Profil seem better than VP7 for lower quant (high quality or "high bitrate"). x264 High Profil is the best codec actually available. Ateme H264 is by far the best codec in this test ... MPEG2 vs all The best codecs (H264 or VP7) are 50% better than MPEG2 MP@ML but MPEG2 MP@ML with good encoder is always a good codec. IMO Mencoder is by far the best MPEG2 encoder for low bitrate ... Annexe - Update 14.07.05 - Ateme codec Full quality update 19.06.05 - Ateme codec Full quality - VP7 7.0.0.7 better RC 17.06.05 - x264 rev 263 Main Profil - x264 rev 263 High Profil - DivX6 - VP7 7.0.0.7 - MPEG2 MP@ML with Mencoder 08.06.05 - x264 rev 253 Main Profil - x264 rev 253 High Profil 24.05.05 - SSIM plugin - Nero Digital High Profil for demo only 22.05.05 - x264 rev 232 - VP7 7.0.0.6 - Libavcodec MPEG4 ASP (MEncoder dev-CVS-050426-18:49-3.4.2) - Libavcodec DivX 3.11 (MEncoder dev-CVS-050426-18:49-3.4.2) - XviD 1.1.0 Beta2 03.04.05 - x264 rev 184 - VP7 7.0.0.4

You encoded XviD at fixed quantizer. Encoding it two-passes will give you a higher psnr. Furthermore, you stated 450 kbps / 6882 KB, which isn't coherent ( 1024 / 1000 issue ). You're better off targetting 458kbps ( the difference been greater than the error margin, those 8 kbps are important ).
I made the test with XviD @ '450' kbps ( actually, in order to hit the wanted bitrate, i had to type 480 in the bitrate box ). I obtained a psnr of 40.49 dB overall ( 41.69 average ). Edit : btw, the loss implied by doing a constant quantizer encoding is 0.8 dB, which is _huge_. I hope nobody still believe that constant quantizer yields better quality that a two passes encoding.

SSIM : 63.72
Settings : XviD defaults + bvhq + vhq4 + GMC Btw, you praise psnr overall over psnr average when it comes to rate control comparison, however ssim is computed as average psnr is, so ssim should only be used to compare frames together, not to compare rate control algorithms.

My results with Xvid:
Streaming.avi size: 6894 KB SSIM_PP4: 64.86 1CD.avi size: 13806 KB SSIM_PP4: 78.27 Settings : XviD defaults + bvhq + vhq4 + GMC + MIN/MAX I/P/B frame 2/31 + some tuning in overflow treatment and curve compression. playback with ( Xvid decoder + PP4 ) or ( ffdshow + Nic's PP4 ) will produce same results.

Sagittaire :
CruNcher and I doublechecked your psnr results for your XviD @ 450 kbps. We obtain an overall of 40.40 and a SSIM of 63.94. How did you manage to get that wrong ? What can we assume for the other figures for the other codecs ? |

@Bobololo
compare is only YUY2 or RGB compatible in avisynth ... i don't understand why ... perhabs function begin in avisynth YUY2 2.0x version but avisynth 2.5x is YV12 now ... You can confirm my result with your AVC codec and with my test protocol ... perhabs you can make better encoding ... ??? @ Manao Problem seem to be ffdshow for MPEG4 ASP class codec ... I will use XviD decoder and DivX decoder now ... update in progress @LordRPI update in progress ... @springl please if possible post your encoding or your setting with complete reg file for exemple: Code:

Which settings were used for DivX? I might be missing something obvious here, but I don't see them. Did you constrain all codecs via VBV, or was this test a mixed bag? Was there any emphasis on comparible testing (e.g. time to encode, CE compatibility, etc.) or was every codec simply allowed to run wild with the features it used?
What were the settings used for WM9? I'm surprised at this result. Also, when you use a decoder you really ought to use the decoder for the codec you are testing, i.e. use the DivX decoder for DivX, the XVID decoder for XVID, etc. Each codec may implement different technologies in their decoder and these are no less a part of the format than any encode-side features. For DivX we recommend full deblock, no dering, no frame delay, no film effect. We notice you also used DirectShowSource. When using this input filter please ensure that the DivX Decoder is configured so that it does not overlay the DivX Video logo during decoding.

Also, you have Trim(70,3144) in SSIM script, and Trim(70,3145) in all other scripts. It causes an error ( SSIM won't work with different-length clips ). You want to change 3144->3145. Last edited by sparky; 2nd March 2005 at 00:35. |

@ DigitAl56K
problem with ffdshow for MPEG4 ASP class codec (i use DivX dec and XviD dec now ...) and I update bench for MPEG4 ASP codec ... For WMV9 I use best quality with complex dec in 2 two pass VBR. I use PP1 DMO for Post-process ... For DivX I use unconstrained, insame quality, H263, multibframe, GMC, Bitrate Modultion = 0.25. You can propose your encoding with setting used if you want ...

not explain for variable length clip ... clip for SSIM function must have the same length and not for compare function. Length problem is perhabs bframe problem for MPEG4 ASP, for RV10 i don't know ... but it isn't big problem with trim modification ...

Regarding your result with our codec, let me know your settings first. Also, there is an undocumented quality level "full" which is insanely slow but that can surely achieve slightly higher figures |

YUY2 test order is not different to YV12 ... there are good scaling with result between YUY2 and YV12 test ... perhabs Average PSNR in YV12 and Overall PSNR in YUY2 will be good solution ... for your AVC codec I use "my best setting" ... lol encavc.exe -i azerty.avs -o clip.mp4 -qual extra -rcmode 1st -log 1pass.log -br 450000 -deblock 0 -ref 5 -setef wpred -cartoon -psy 1 -priority idle encavc.exe -i azerty.avs -o clip.mp4 -qual extra -rcmode 2nd -log 1pass.log -br 450000 -deblock 0 -ref 5 -setef wpred -cartoon -psy 1 -priority idle Quote:

Sagittaire please keep the values correct the XviD-450.avi is not 450 kbps as stated in the table it's 457.0 kbps

All my files are upload and hyperlink in post ...
And 450 must be 450 Kbit/s too (like for VP6 or WMV9) ... in fact the most important for size/bitrate is to respect [6810 Ko - 6960 Ko] interval and [13660 Ko - 13940 Ko] interval. With same codec/setting difference between 2% for size is very small for metric (perhabs 0.1 dB for PSNR and 0.1 for SSIM)
