madVR - high quality video renderer (GPU assisted)

[sucht]

i just swiched from XP(SP3) 64bit to Vista 64bit and Windows 7 64bit, i never had a real big problem with this renderer, but now on Vista 64 and Windows 7 64 i get this Macrovision Fail thing everytime i try to play one of my many DVDs(NTSC and PAL)
is there a workaround for this or do i have to switch to another renderer?


thanks and ciao

It could be that on the 64 bit versions of Vista and Win7, the protected media path allows only signed components to be loaded during playback (so that nobody could dump the video stream). That would make it impossible to use unsigned components (like ffdshow or madVR).

Luckily that's not the case, as every renderer except MadVR (and even with MadVR some discs do work)

Why Madvr 0.10 doesnt have the two 3dlut files ?
and how do I use them? just copy them from the 0.9 release and put them in the folder where madvr is?

Is there plans for a x64 version?

HR doesn't care for .ICM files because it's not color managed..but it does care for LUT files in ARGYLLCMS(actually all the renderers do, except Overlay)

anyway, ARGYLLCMS is far more accurate than any other color calibration package, especially in "HQ" mode

I speak about icm profile created by lacieblueeye pro (hardware color calibration). I don't know what lut means but All I know is that madvr doesn't support color profile like overlay renderer and it's a big problem because powerdvd (except for blu-ray), windows media player, vlc, mpc-hc with vmr7,vmr9,evrcustom support color profile.

I hope that madshi will correct this problem ifnot madvr will be useless now and maybe even in ten years because It doesn't exist one monitor well calibrated in the world without hardware calibrator (ie deltaE<1 for all colors). Maybe i nten years it will be different but not today.

anyway, case closed...if mVR does take the graphic card's CLUT in account, there's nothing to see here

@ikarad: I also have the Lacie BlueEyePro(rebadged i1d2), their software is awful...try ARGYLLCMS, I've discussed its usage thoroughly on HCFR w/ MLill

something like "dispcal -v -yc -t6500 -g2.3 -qh test"

PowerDVD works with color profile except with blu-ray mode (here color profile is desactivated under vista or xp).

Lacie blu eye pro software is very good. It works very fine.

The idea of the 3DLUT is to achieve the same thing as the icm profile, accurate colors per standard in any display.

[leeperry]

how big is your .ICM file? probably it contains a LUT already...I never really bothered w/ the Lacie software, coz ARGYLLCMS does a finer job anyway..and ARGYLLCMS is fully compatible w/ any video renderer except Overlay.

how do delayed frames alter the viewing experience? with dropped frames, there is stuttering, but how do only delayed frames change the look of the movie?

ok so it doesn't contain a LUT.
last time I played around w/ some color management app from X-Rite it gave the option to create 1D LUT ICC files.
I'm surprised PowerDVD is color managed and will take the simple ICM file in account ?! anyway, play around w/ ARGYLLCMS it's much more accurate and works perfectly fine w/ any video renderer(except Overlay...but PDVD uses VMR9 anyway, last time Jong checked anyway )

atm I use a LUT in ARGYLLCMS to fix my CRT colorimetry, then ddcc() in ffdshow to convert gamuts w/ HR.

They are auto-created when needed for the first time.
You can edit the templates in madvr cr3dlut folder.
What are exact rules which template is used and when I don't know but I presume it is resolution of the video among other things.


ikarad, I use display calibration as well and madvr works fine with it (Coloreyes Display Pro), it has a special lut loader on windows startup so I guess it is not dependant on Vista's ICM support.
Just saying so you know it is not all black and white.

Found a small bug with the installer. Running install.bat as admin fails to register madVR. You have to run install.bat as a regular user, then click yes to the UAC warning. I'm on windows 7.


madVR is working except if you... pause video > resize > play... it crashes. I'm guessing that's been brought up already, just thought I would mention it.

Keep up the good work

About supporting YUY2... I've just been using the really excelent DScaler5 MPEG2 decoder to playback some TV shows. By default, it outputs YUY2, and the video looks truely dreadful because some grotty little default video renderer gets loaded in place of madVR. I finally worked out why madVR wasn't loading and I've set DScaler5 to output YV12 instead (BTW, how exactly is YV12 better than YUY2?).

I was thinking madVR being fed with YUY2 is still better than the alternatives being fed with YUY2. If madVR could support YUY2, and perhaps display an on screen warning message for 10 sec or so. Would that be a good idea?

Yeah, but as explained before, YUY2 is not YV12. Videos are in YV12 so if mVR is to accept YUY2 then you would rely on potentially substandard chroma upscale in the decoder.

I think current implementation is more reasonable.

Hi, I've got a basic understanding of color spaces. Do you have a link to where you explained it before? Does all video use YV12? What about high def videos like straight from blu-ray disk?

Unfortunately YV12 is what is used in practice. YUY2 has more colour information compared to YV12. In simple words, if you force decoder to output YUY2, then it has to do the chroma upscale. Potentially it can do it substandard. The point of mVR is to have no compromise in quality all the way, so it cannot rely on other filters.

I didn't explain it before though, it is an explanation by madshi, so you have to look it up in one of his monster sized posts

If you want to get some proper understanding about colorspaces, you may try this: http://en.wikipedia.org/wiki/YUV

I use the Unofficial 1080i IVTC version of Dscaler5 MPEG2 decoder to perform IVTC on TS files - it's the only decoder that finds 23.976fps in the 29.97fps stream.

To get around the YUY2 thing I run Ffdshow after in the filter path - Ffdshow outputs YV12 to madVR.

It may not be ideal, but it works, and you can play with ffdshow filters too

[ajp_anton]

So you're going mpeg2 = YV12 -(dscaler)-> YUY -(ffdshow)-> YV12, and then madVR for its chroma upsampling quality?
