@Madshi
Two things: 1) external command seems a bit flimsy, even on enable. I've created a group profile testing HDR, and selecting a custom profile for calibration based on content (SDR=select Rec-709 calibration on the JVC, HDR=select SDR-BT2020 on the JVC). Although the correct profile is selected based on content, the external command on enable seems hit and miss. It should execute every time I change content type, but it doesn't. I haven't identified a pattern, but I think it was working all the time earlier because it was always the same profile that was selected. I tried reverting to the official build but I get the same results as the test build. EDIT: in case it helps, if I switch the user mode to call in the custom enable field, the mode changes right away when I click apply (if the profile is active, of coursE), in real-time. So it's not the batch file. It seems to be that in some cases but not always the command is either not sent on profile enable or missed. There is no other app using IP on the JVC and I always make sure that the PJ is stable before starting playback (as no command is accepted during HDMI sync). 2) Is it just me or has vertical shift according to A/R stopped working in the latest build? I haven't changed anything in my settings, but the picture isn't shifting anymore according to A/R.

Interesting setting, I never paid it any attention until now.
I would make sure to have a profile set up for using this specifically for 4K content only, it does however make the picture less sharp when it's enabled and it's obviously now not using my set chroma scaler (NGU AA) according to the OSD and changing the scaler makes no difference to the picture so it's using bicubic 150? which is my luma downscaler for 4K. Quote:
Thing is on my 960 is drops render time from about 30ms on The World in HDR to about 8ms.. but there are obvious differences in the picture which you can see from the screenshot below. However, setting this also allows me to preserve the hue from HDR in high quality which IMO looks slightly better than it being in low quality and not scaling chroma separately with NGU AA. That with HALF the rendering time is quite nice, I can deal with this on my 960 at only 15ms. I guess everyone with lower powered cards should consider using this combination of settings for HDR. The_World_in_HDR_in_4K_HDR10.mkv Let madVR decide scale normal The_World_in_HDR_in_4K_HDR10.mkv Let madVR decide scale separately The_World_in_HDR_in_4K_HDR10.mkv preserve hue HQ and scale chroma separately Okay, so this file requires chroma upscaling which isn't the norm for 4K content when downscaling to 1080.

Are you watching 4K content on a 1080p screen? If so the chroma does not need scaling, on a UHD bluray the chroma is 1920x1080.

Question about HDR > SDR tonemapping settings with a JVC RS600 projector
Quote:
I've read a lot of your informative posts on Doom9 and the AVS Forum (RS 500/ 600 thread), including your post today regarding the state of HDR on the JVC projectors. I was wondering if you could share the settings you are using for tone mapping HDR > SDR in madvr. Specifically, the peak display nits setting appears to be a matter of guesswork. madshi previously indicated that a minimum setting of 265 nits should be used regardless of the display's actual peak brightness. You mentioned that you had experience calibrating SDR BT.2020 in Calman. I recently upgraded from a JVC RS49 to an RS600. I calibrated SDR/Rec 709/Gamma 2.4 manually with an i1 Display Pro and Calman, and then perfected the results in Calman with a madvr 3DLUT. I would like to do the same for SDR BT.2020 but the process seems more complicated. My understanding is that it is necessary to set the colorspace to Rec.2020, but because the JVC projectors are limited to the DCI-P3 colorspace with the filter engaged, I should use DCI-P3 saturation sweeps. Is this correct? Presumably, I would do the same for the 3D LUT generation. I assume I will need to open up the iris more and enable the filter. Regarding my setup, I calibrated SDR/Rec.709 to 13 Footlamberts (Low, -10 Iris) with my 120" white unity gain screen but could go brighter for tonemapped HDR > SDR content. I have a fully light controlled room with no ambient light. The walls and ceilings are coated with black velvet 10' in all directions, with a black rug on the floor, and I have dark grey ceilings and dark navy blue walls extending farther back. I plan to cover the entire room was velvet over the next few weeks. I also use black velvet throws to minimize reflections off my leather couch. Quote:
First, I would like to say that I am extremely impressed with madvr. The NGU Sharp upscaling provides a very sharp image without visible artifacting, and I'm viewing content on a 120" screen from 10-11' away. In addition, the 3D LUT calibration yielded average deltaE errors for greyscale tracking and color under 0.5 with maximum errors of only 1.5. Really amazing results for almost no work. As for your question, I think this would be a useful option. I'm using NGU Sharp (High) on a GTX 1070 for 1080p content which yields RCA for free. However, I discovered that this option is tremendously demanding when used on 4K content. It increased render times from approximately 30 ms to 80ms(!) when used in conjunction with NGU AA (Medium) for Chroma, as well as Light/High debanding, and the deringing filter. Removing the debanding filter (probably not necessary for 10 bit high-bitrate 4k BD content) and the deringing filter lowered my rendering times to 15 ms. I ended up creating profiles for each resolution as you suggested but a checkbox option would be easier. Moreover, it wasn't obvious to me that RCA was so demanding. Given my experience, it seems to be one of the most demanding options available when used at 4K. Last edited by jasonwc18; 19th January 2018 at 01:25. |

I'm still experimenting and apart from agreeing with Mashi re the peakY value (I used 200nits initially for a 120nits actual peakY, but I find that up to 400nits looks very good) I need more time to find the best compromise. See you in the JVC thread

Your image links aren't working.
You've probably already done this, but have you checked and confirmed resetting to default settings without profiles to make sure the option(s) work as intended in the basic scenario? If that is the case, it'll make it easier for us to confirm if we have the same behaviour. |

Fixed, copy paste fail.
I'll try a fresh profile, what the heck, my OSD isn't displaying with screenshots either so maybe that might fix that too. Profile garbage =/ Nope, didn't fix either, seems The World in HDR needs chroma upscaling. Haven't seen this with any other 4K stuff. Last edited by ryrynz; 19th January 2018 at 02:31. |

and for some reason people just like to uncheck everything in there. defaults are defaults for a reason just say. edit: sorry could you add screens with the OSD so i can have a real look at what is happening with advanced rendersteps? Last edited by huhn; 19th January 2018 at 06:09. |

I think chroma upscaling option means downscaling as well...
I downloaded the latest MadVR 0.92.11 and must report that I can now play, on GT 1030, UHD HDR 60 fps with HDR conversion on max settings, scaling is DXVA, chroma upscaling set to NGU: Sharp very high quality...can't say that switching chroma scaling between separately or not effects the playback...can't say if I did something wrong before and it's actually not up to the new version...

Bit of a weird request, but would anybody have, or could produce, any 1080p test samples in both 4:4:4 and 4:2:0 uncompressed formats?
I'm trying to compare 4:2:0 material with Bilateral and NGU chroma upscaling to the original 4:4:4 material and so far the only samples I've found are 720p ones from Xiph (search for 4:4:4 in the page), and ideally I'd want 1080p ones (I know they'd be huge, but it's just for testing). My impression from testing with the in_to_tree and park_joy samples is that NGU is better with most content unless there are on screen generated graphics, text (including text present on real objects from the scene being filmed), or very contrasted edges with red colour, (Edit: also, cartoons and anime), cases for which I prefer Bilateral because NGU gives weird artefacts which I spot even when simply watching some programmes on TV. I thought about using photos from my camera converted from raw, but I'm not sure if the chroma downscaling used when saving as a JPEG is comparable to the one used by professionnaly produced video (and also I'd like to avoid JPEG compression adding a variable to my comparisons). Edit: also, does anybody know what algorithm is usually used by the movie/video industry tools to downscale chroma for 4:2:0 ? Quote:

Is it possible to call a batch file in an external command in the custom profiles with a variable, such as test.bat variable
I tried with quotes: "test.bat variable" but that doesn't seem to be working. Thanks!
