I think so. But I still have on my to do list to revisit AdaptiveSharpen, compare the old to the new version, and maybe tweak it all over again. Quote:

But in the end it sums up to that the majority of users wanted it gone (I think). Maybe it'll come back some day as an option, together with lots of other similar notifications. I don't know yet. Of course if there are many users who're opposed to me deleting this notification, we can do a vote and check how many users want it vs don't want it. But so far you're the only one who's complained. Anybody else unhappy about this? Quote:
FYI, another film maker paid me good money to make the HDR -> SDR algorithm available to him via VapourSynth. He's now grading all his films (ads mostly, IIRC) in HDR only, and lets madVR do the SDR based on his HDR grade. Saves him a lot of time... Quote:

That should already be the case! The only exception is if you have a "?" device, in that case the settings dialog always jumps there, to motivate you to tell madVR which display type it is. |

What's great about MadVR's conversion is that the only thing you need is a good SDR BT2020 calibration, which is easy and straightforward to create, at least as a baseline. I've looked into this a bit more and here are the main issues I'm trying to solve: 1) If using "process HDR", it works great with an SDR BT2020 calibration in the projector, but I can't apply a 3D LUT anymore. Ideally, I would like to be able to apply a 3D LUT (generated in Calman with a BT2020 SDR Gamma 2.4 target) to improve my baseline, so that the calibration is perfect, yet still use MadVR to do the HDR>SDR conversion. I don't see an option to do this at the moment, but I might have missed it. If I select "your display is already calibrated" pointing to a BT2020 calibration to get SDR BT2020 with Pixel shader math, I can apply any 3D LUT. 2) In order to get the best SDR BT2020 calibration for HDR, I need to open my iris wide, select high lamp and select the filter, to maximize peakY and gamut cover. This gives the best result for HDR content (would be even better if I could apply a 3D LUT without losing MADVR's pixel shader conversion), but it's not ideal for SDR: loss of on/off contrast, higher lamp noise and lower lamp life. I don't really want to keep this calibration on all the time and let MadVR convert to rec-709 etc. 3) This means that I have to select my SDR BT2020 baseline when playing HDR content, and only when playing HDR content. For all other HTPC content, I have to select my rec-709 calibration, which is completely different (lower iris setting, low lamp, no filter). I already have 3D LUTs for this (and PAL/NTSC) that I would ideally like to be able to go on using. Unfortunately, as I have to select "your display is already calibrated" with a BT2020 calibration to get SDR BT2020 out of the pixel shader conversion, I don't think I can keep using these 3D LUTs profiled from my rec-709 baseline/calibration in the projector anymore. 4) I could use the external command when playing HDR content (I already have a separate profile for HDR to deal with 4K60p content, as you might remember that there is a bug in the JVC with that content if metadata is sent with passthrough, so I disable metadata specifically for this at the moment), and then bring back the rec-709 calibration when leaving the HDR profile. However, I understand that the feature is broken at the moment. I also have no idea what the commands are to control the JVCs. I mean, I know the JVC commands, I use them with iRule or the Vertex, but I don't know the syntax to send them from a command line with MadVR. 5) I don't need to have the metadata sent to the Vertex when MadVR is doing the conversion as it seems to be doing such a great job. If I find a way to select my SDR BT2020 calibration on the projector when HDR content is played, that's fine. 6) As I need other calibrations in the projector for non MadVR sources (such as my bluray player for x.v.color and 3D, my UHD Bluray to stream SDR, HDR and HLG content, my Humax Satellite box etc), the easiest way to go for me would be to keep using the Vertex to switch my calibrations automatically in the PJ for any kind of content, and when MadVR plays HDR to get MadVR to select my SDR BT2020 calibration and do its magic. The Vertex selects the calibration according to content (I have one SDR rec-709 for film, one for TV content with frame interpolation, one for 3D (until the frame drop every 3mn issue is fixed with nVidia, I'm still using my standalone player to play 3D whenever possible), one for HLG Rec709, one for HLG BT2020, and one for HDR10 (which wouldn't be used with MadVR). MadVR then adds either its 3D LUT (for Rec709, PAL and NTSC, all based from a single rec-709 profile) or its HDR>SDR conversion (for HDR10). Ideally, as discussed above, if I could also get an SDR BT2020 3D LUT applied (on top of my SDR BT2020 baseline calibration after a JVC Autocal, to improve further the accuracy) when MadVR does its SDR conversion, that would be great. 7) What I don't want for MadVR re HDR10 is either MadVR doing only the processing (I'd rather use passthrough in that case if the display still has to deal with PQ) or MadVR applying a 3D LUT that would also do the tonemapping, as Calman doesn't support BT2390 yet and I suspect the result wouldn't be as good as MadVR anyway, due to all the options available in the MadVR pixel shader conversion. Lightspace supports BT2390 but I'd rather do all my calibration from Calman. I hope it makes sense. Please let me know if you have any suggestions or if I got something wrong with this initial assessment. It's a complex cinema room set-up, so I might have missed a far simpler way to do this. Otherwise, for me the questions/priorities would be: 1) Is there a way to get the MadVR HDR to SDR conversion and still apply an SDR BT2020 3D LUT to improve the accuracy of the baseline calibration in the PJ further, without losing the pixel shader conversion? 2) Is there a chance for the external command in the custom profiles to be fixed in the near future, and if yes please could you point me in the right direction regarding the way to pass JVC commands to the projector using a batch file? I don't need the JVC commands themselves, only the way to send them (and which format I'm supposed to use). Thanks!

Hi Guy's,
Been using a pre-hdr version of madvr for some time with no issues with my Dell monitor (used for desktop/web) and my Denon AVR - LG TV as an extended display (for movies), both on intel HDMI motherboard outputs. I have just updated my PC to an 8700K system for UHD playback and installed the latest madvr, however my displays are not being correctly detected My Dell is listed as the only detected display but the identification EDID within the Dell display properties is my Denon AVR and every time I use the Denon a new identification appears under the Dell display device, again showing the Denon edid, these Id's just mount up each time I use the Denon-TV display, weird. Can anyone help in fixing this issue, I've added an image snip of madvr devices page - showing the Dell display and numerous identifications within it, each id has been created every time I use the Denon - Tv display. Thanks for any help. https://i.imgur.com/4w4aH85.png Last edited by -Hitman-; 16th January 2018 at 22:02. Reason: image link |

Hi, it was a straight bluray UK bluray remuxed, not sure, cant seem to pull that info from mediainfo. Control J clocks it as BT709 but there is some more odd behavior. If I play the movie with calibration disabled its all overblown in red like I say. If I then press control s to bring up the settings, when the settings screen comes up the colour reverts to normal like the rendering path is being broken, this is with FSE off using MPC-BE. What I have also noticed is that setting MADVR calibration to Bt.2020 it even more natural, DCI-P3 was still a bit red. With MADVR set to b3.2020 the colour is almost identical to standard EVR rendering in MPC. Any idea what going on here Madshi? Last edited by mclingo; 16th January 2018 at 23:31. |

I vote for a simple toggle, even via registry key, to enable it if we want.
I use madVR mainly for its perfect stability, and the windowed/exclusive info is the most important to me (replying as to why this info versus others), besides the code already exists ^^; As sometimes i'm swtching from 720p@60 to 1080p@24 and madVR doesn't always go to exclusive mode in that case, with the OSD at least I know.

I'm sure you sent me a sample, I probably didn't have time to look into that yet. I have a folder with "black bar detection" samples that I need to look at, when I find some time. Quote:

Hi all,
probably a dopey question but it's been a long couple of days and I'm having one of those pandora's box situations, where I was initially trying to do something that I thought would be straightforward, but have now had to teach myself half a dozen different things to make it happen Basically I started off by trying to calibrate my new TV about a week ago, but quickly discovered I have colour space issues with parts of my chain... long story short I was looking for an alternative way of running calibration patterns on my TV via my laptop, but discovered that for some unknown reason my laptop (Dell xps15 9550) plays the 0-255 black and white clipping files (mp4s from AVS HD 709) as 16-235, or at least I think that is what is happening, there is no information showing from 0-16 or 235-255. Where I am slightly confused and the reason I am here is because the only way I can make the file play back correctly on my laptop is by selecting 'TV levels (16-235)' in the properties tab of MadVR. I'm probably being very stupid here and missing something very obvious, but this is the opposite of what I was expecting. Why does 16-235 reveal the information and 0-255 clip it? Have I done something wrong? Cheers |

if they are >not< shown than BTB and WTW are properly clipped as it should be. |

I can even enable and disable 3D on the fly during runtime by setting keyboard shortcuts on the 3D profiles, simply amazing! Finally we have fully automated switching for both 3D and HDR on nvidia. Thanks again madshi for this outstanding release.

Great news, will be very useful for 3D and nVidia users, sorry if I missed this in the change log. So do you have an answer to my question: how do I select the calibration in the PJ with a batch file? I don't need the JVC commands themselves, I know them, I just need to know how to send them from a batch file. A user has posted how to do it in Python in the JVC thread, but I don't know how to call a python script from a batch file. So any information (ideally an example of a batch file sending any command to the JVC) about achieving this would be very useful. Thanks!
