And then the RGB 12 BIT FULL @23 hz for HDR/MADVR movie playback? Isn't it weird to use only 8 bits for HDR games? |

No, they dither too. 8 bit is much better than losing 1/3 of the video data (YCbCr 422) or running 30 Hz. Can you tell if the game is running in 8 or 10 bit? Of all the things you can sacrifice the bit depth has the least impact.
Have a third party randomly change it and then try to determin what the bit depth is, do you do better than 50:50?

@chrisssj2 you don't need to quote an entire reply consisting of answers to your questions when you post. If there are many branches of conversation it can be useful to quote but there's no real need when the topic is focussed, it just wastes space on the forum, cheers.

Does anyone have much experience with the anamorphic lens option in madVR?
I am helping set up a new HTPC for a friend and we put in a RTX 2070. Anyways, with the settings we are using the render time is about 28-30ms which seems decent. However, when I enable the anamorphic lens option, the render times go way up to 130-150ms! Also, the anamorphic mode on his actual projector will stretch the content off the top and bottom edges of the screen (which is intentional). Like if it's a 16:9 native video and he wants to view it on his 2.40 screen, the 16:9 needs to be vertically stretched where the top and bottom get stretched off the screen. How can you do this with madVR anamorphic mode? I tried playing with the stretch numbers, but I can't get it to stretch the video vertically off the top and bottom of the screen. Maybe I have to use the "define visible screen area by cropping masked borders" feature? I just assumed madVR would be really flexible with this sort of video manipulation, but I just can't seem to figure it out. Anyone have any insights on either of these issues (the terrible anamorphic stretch performance) and (getting 16:9 content to vertically stretch)? Last edited by SirMaster; 10th May 2019 at 16:35. |

a screen of the OSD should help but using a lens can increase render times heavily you have to do at least an extra scaling.
if you mean with stretching of the screen cropping you have to tell the player to do that that would be touch window from outside in MPC-HC no sure why someone would do something like that and removes big parts of movies but that'S how it is done. |

I think leeperry just raised this issue a few posts earlier: when using 'touch window from outside', image gets scaled to bigger than screen size and then displayed with areas outside the screen, which wastes GPU, instead of being pre-cropped then scaled to full screen.
Also, when using NGU in combination with anamorphic scaling you can possibly end up using two different scaling steps depending on how you configured NGU settings. For example I get this with broadcast SD when scaling to FHD: luma x: 720 > [NGU] 1440 > [selected upscaling algorithm] 1920 luma y: 576 > [NGU] 1152 < [selected downscaling algorithm] 1080 Even if I choose the exact same algo for both upscaling and downscaling in NGU config, e.g. Lanczos 3 AR, the OSD still shows two different scaling steps for x and y.

Honestly I just want a simple scale for the stretch heh. I can post my madVR settings and my OSD later tonight. |

I'm not sure it's two NGU steps, I think it doubles with NGU, then (for my example) upscales in the x direction with the upscale algo, then downscales in the y direction with the downscale algo, so 720x576 > 1440x1152 > 1920x1152 > 1920x1080
But I may be wrong. I'll check later with ShowRenderSteps.

Alright, madvr, let's see what you got. I just upgraded my HTPC to a 9900k, 32 gigs of 3200 ddr4, and a founder's edition 2070. I'm tired of being on the edge of UHD playback. Now to re-tweak madvr after I get this clean driver install done and configured for these new 20xx cards.

This is not an HTPC but a power plant!

Is there any way to use the Nvidia noise reduction with madVR? I'm fed up with the grain/noise added to some UHD videos. I've tried all the decoding options but it doesn't work. I'm testing the Gradual Denoise from ffdshow now, but the performance is not very good and produces some artifacts. Some other alternative?

Have you tried madVR's?
There is no way to use Nvidia's but madVR's processing -> artifact removal -> reduce random noise on 2-4 works pretty well for me, on content with grain that bothers me.
