Catmull-Rom, Mitchell-Netravali and Spline is one group and
Lanczos is the other with cubic in the middle.

The Chronicles of Riddick is a good movie to experiment with the effects
of the various algorithms that MadVR provides.

Luminance and Chrominance are vastly different creatures. The former
is the reference intensity of one of the primary color signals and chrominance
is a pair of values containing the relative intensities of the other
2 primary colors, the color difference signal.

In simple terms the Luma channel needs a good 1D reconstruction filter and
chroma needs one that works well in 2D. Mitchell-Netravali and
its derivitive Catmull-Rom was originally designed as a 2D image reconstruction filters

What calibration hardware/software did you use to generate your 3dlut?

You will need yCms to generate the 3d LUT table

Put the generated files in the madVR directory

I have a issue with MadVR and video levels. Setting MadVR to output 0-255 (and using custom Nvidia resolution) I get black crush in exclusive full screen mode. In windowed mode video levels are correct. Disabled exclusive fullscreen mode and video levels match between fullscreen and windowed mode.

MadVR .61
LavCUVID .7
LAV Splitter/Audio .28
MPC-HC .3018

Is exclusive mode running at the same resolution and refresh rate as windowed mode, if not you might have to define a custom resolution for
exclusive mode as well.
Best to check what your TV says and not rely on Windows.

This problem with Nvidia's driver is pretty tiresome.

Your version of MPC-HC is also getting old. .3177 is the current version,
MadVR seems to work better with the later versions.

Just a quick question, why not use Lanczos or Spline for Luma sampling in MadVR?

I'm just getting to try this out on my test PC with a NVIDIA 8600GT...
The image quality with madVR (+ LAVCUVID) is freaking awesome...

The only current issue is that the subtitile option is greyed out in MPC-HC while using madVR, but subtitles work well with EVR.

I am using the latest LAV, latest MPC-HC tryout, but on vista 32 bit.
Can the subtitile problem be due to vista?

My main HTPC runs win7 with a GTX460... will try setting it up there after Roland Garros is finished today...
In the meanwhile, if anyone has subtitles working with madVR kindly share your settings

Thanks.

I'm Sure it will work better with the gtx460, the 8600gt only has like 15 stream processors compared to like 330.

Well this is a fun thread! Tong Chia, thank you for the invaluable information. I just generated 3DLUT tables for my main HTPC. Remarkable. I'm using MC16 with madVR. Man what an awesome combination.

so after uninstall lav, mpc 64, 32, and reinstalling lav, mpc32, madvr (finally), now 32bit cuvid will not register. (i unpacked it to a folder labeled "lav" in the root directory of C:


C:\\LAV>cd /d "C:\\LAV\\"

C:\\LAV>regsvr32.exe LAVCUVID.ax

C:\\LAV>

I get an error about:

module failed to load. make sure the binary is stored in the specific location.

any ideas?

Make sure you get the latest cuvid. It doesn't require the MSVC runtime. Also, madVR 0.62 just came out and has HUGE changes that will affect this crowd. Please go check it out ASAP.

Since installing my GTX460 last November, I never got anything so thrilling out of it 2D wise.
The only issue I'm left with now is subtitle related... I just can't get sutitles to work.
I am wondering if anyone is using the LAV-LAVCUVID-madVR combination in 7MC... is it possible at all?
Anybody got subtitles working?

In MPC-HC, I get a pop up window telling me that I have to switch renderer to EVR, VMR9 et al if I want subtitles. I guess something still needs to be done in madVR for subtitles to work.
Anyone got suggestions?

Thanks.

Nope. LAV CUVID 0.8 was released this morning.

You won't with just that. You need something that displays subs in the chain. You don't have that. You can add ffdshow raw video decoder to that chain and it should work. That's what I use.

To deal with subtitles you could also download and register vsfilter.dll from MPC-HC standalone filters (here).

Sorry, I saw it on first page and deleted my post. Anyway, try unregistering it (e.g with Graphstudio) first, then install it.

Yikes. I've not seen that issue. You might want to post that in the LAV CUVID thread on Doom9 and see if Nev has any ideas. (Try Tulli's idea first)

I only have ati cards right now and i culdn't get decent frame rate on anything less than 120 stream processors.. does madvr do something unique to handle lower sp count on nvidia?

Then I would see if Nevcairiel has any ideas on the LAV CUVID thread. I don't know what could be causing it.

He doesn't answer PMs and he is very blunt.

He might help but he wants specifics.

And when I say specifics I mean S-P-E-C-I-F-I-C-S if you know what I mean.

Thanks,

But how do you add the ffdshow raw audio decoder in the chain?

I have enabled raw video support in ffdshow and added it to the list of filters in MPC-HC, but it still doesn't work

I also registered vsfilter and subtitles don't work either.

All of this is in MPC-HC 3177.

Thanks.

Raw video decoder. Add it to the preferred list in the external filters screen. Open up the properties and make sure it's set to use subtitles. But, if you're using MPC-HC, I would just use MPC's subtitle renderer as the later versions work with madVR. I use ffdshow raw video decoder because I use a different player.
