madVR - high quality video renderer (GPU assisted) - Page 2575

The colors might be oversaturating with it turned off. Enhanced colors produced by BT.2020 (DCI-P3) should be subtle compared to BT.709. The difference in gamut size is only 26%. It all depends on what color space you set your projector to. You should match that in madVR.

It is more likely the gamma is different with calibration controls disabled. When disabled, the gamma defaults to 2.20. When active, I think you are using a 2.40 gamma. Try changing the gamma setting in madVR with calibration controls enabled. It should produce a similar result. You don't have to match the gamma of your projector for HDR -> SDR. And the gamma setting won't impact SDR playback.

I just bought a variable refresh rate monitor. When playing 23.976 content should I set the monitor's refresh rate to 48Hz to avoid judder from 3:2 pulldown? Normally it's set at 60Hz.

SamuriHL · 22nd June 2018, 21:38

Try it and see how it works. I use 48Hz on my plasma screen and it works fairly well.

Thank you for this.. I will definitely try it

Stupid question.. Is DCI - P3 same as BT2020? When I press ctrl+j to see what madVR is displaying it says BT2020 -> DCI P3 is that what it's supposed to be? Thanks

No, different colorspaces.

Rec.2020

DCI-P3

huhn · 22nd June 2018, 22:48

DCI P3 is not the same as BT 2020 far from it.

it is most likely processing in DCI p3. there is no screen that can do BT 2020 and even DCI p3 is barely doable-

Hmmm I see.. Even though my JVC says BT2020 u guess it can only do DCI P3 then....?

Hi guys!

Can anyone please point me in direction of solving following issues.
I'm trying to use MPC-BE + madVR + external LAV filters to watch IPTV from my internet provider (UDP multicast stream).

1 problem is that with some channels, and most disappointing the channel that is broadcasting TV matches, playback stops after several seconds. To be clear - nothing crashes, playback just stops when using madVR as render (with other renders playback doesn't stop).
Other channels seem to work fine. Moreover, after oppening m3u playlist with several channels and switching them back and forth non-working channels seem to start working. Any ideas?
2. Deinterlacing done by madvr produce artefacts on moving objects. Clearly visible with moving text on news channel. Is it unavoidable or maybe I could tweak de-interlacing options somehow?
3. Before playback starts it hiccups for second or two with static picture. Tried to increase-decrease queu size and enable/disable option 'delay playback until render queue is full' but it doesn't help

Thanks!

are you using d3d11 for decoding?

mkohman · 23rd June 2018, 09:47

Guys apologies in advance if this is going to ruffle some feathers or if this topic has been discussed before....

My current setup is as below :

HTPC >JVC

My HTPC is set to RGB FULL 444
madVR set to 0-256 10bit
JVC projector set to Enhanced / RGB

LAV filters also set to 0-256

My JVC info panel displays RGB when a movie is being played, however everyone else's seems to be showing YUV???

I have Googled JVC YUV OR RGB and in the images section of Google they all seem to display 12bit colour and YUV where as mine displays 12bit RGB...

I use KODI DSPLAYER with LAV filters which are also set to 0-256.. Basically everything in the chain is set to RGB FULL 4.4.4...

Can someone please tell me if this is correct and if so why does everyone else's displays information tab show the colour space as YUV?

Thanks

because you are sending RGB.

changing the settings in lavfilter to RGB is a very very dumb idea leave it at default.

Thanks but, I think it was at 0-256 by default in lav filter.. shall I change that to 16-235? Also shall I change madvr to 16-235? and keep my HTPC at RGB FULL 4.4.4 and JVC input level Enhanced? Thanks

the point is not this setting alone it doesn't do anything with madVR but with a combination of other settings. but for what ever reason you like to change everything that is fine by default and correct by default.

sounds wrong to me.

mkohman · 23rd June 2018, 14:15

No offence but what you have just written makes absolutely no sense.. I don't understand what you're trying to say. I am asking a very simple question and in return I got a string of sentences which made absolutely no sense to me.. Sorry..

Thanks for this. Much appreciated but still no idea which to select for madVR or lav filters? Should they be YCbCr or rgb? Thanks

the YUV or RGB you see at your projector has nothing todo with madVR or lavfilter. it just tells you what the GPU is sending and RGB is fine.

use the default settings for this madVR lavfilter they are there for a reason.

Judging by the images attached below which were both taken from the Kodi Wikipedia Website... I understand that this should be correct :

Desktop set to RGB FULL 4.4.4

madvr set to 0-256

Lav filter and JVC projector set to 16-235

I'll be happy to be corrected if I'm wrong.. Thanks for all the input..
