LAV only dithers when it has to convert the output format. If you use madvr and don't deactivate any of the default output formats in LAV Video this basically never happens. Like nevcairiel said: never turn off dithering in madvr. It's necessary as madvr does all kinds of processing (like chroma upscaling) in high bitdepth.

@Manni
Would you please check if 418.81 passthrough still sends bogus metadata? Edit: You have already answered that in another thread, Thanks!

Most people should probably never touch any of the dithering settings, and they would get an optimal experience that way even.

I've always wondered, because it always looks the same on output, so I just assumed madvr was doing everything ?.

I have the new JVC NX9 projector and want to try using the pixel shader tone mapping in madvr rather than the auto tone mapping in my NX9. However since Im new to this and dont understand, what "target peak nits" setting should I use on madvr for my NX9 projector? Thank you in advance...

Looks like that projector is somewhere around 185 nits max. I could be off so hopefully someone else chimes in that knows what they're talking about (hint not me! LOL)

I feel that the proj isnt quite bright enough on their auto tone mapping as they have a slider for different size screens and gain, however they give no advice where to place the slider, its defaulted to a 120" screen with a gain of 1. I want to test the madvr auto dynamic tone mapping to see it its better than the one in JVC. madshi said its very easy to setup but I just dont understand about the nits and what number to use for that setting.. Even a Google doesnt help my in this case.... |

Try 175 to start (below your max nits or what I believe is your max nits anyway) and see what it looks like. You can always adjust it until it looks the way you want brightness wise. It might take some playing around to get it set up just the way you want, but, start there and see what happens. If it's too dark, try lowering the target nit until it looks right.

I have only been messing with HDR for about a month now, and the more I read, the more I do not understand what to do with it. It seems there is no real calibration settings for HDR and you for the most part have to let your TV do its thing, I also have no idea how people know what is good or bad. Initially I was impressed with HDR but I don't have a dark picture that everyone speaks about, and I don't really want a dark picture either. |

Probably they don't, but they just like the result. Not to mention that every manufacturer can literally do whatever they want with HDR10, there's no strict standard for it. Me neither. Hence I have set target nits to 120 in latest madvr beta with using gamma 2.4 3dlut on gamma 2.4 screen (although I just learned that's not the desired setup) and I don't have to adjust anything else and the picture is amazing (at least for me)

so it kind of lowers "CR" and there is no way around that. there is a diffuse level which is far away from the black so they should be untouched for the most part. |

It would also help to use the current test build found in Soulnight's thread: https://www.avsforum.com/forum/26-ho...rget-nits.html. There is actually a new test build available if you browse to Page 24, Post #712 that hasn't yet been added to the first post. To use the test build, extract the zip file into the madVR installation folder overwriting existing files. madVR must be closed when you do this. I prefer "highlight recovery strength" set to "medium," but higher values can also work. Make sure you uncheck all of the checkboxes related to tone mapping under "trade quality for performance." The other options have been simplified in this build. If you get that far and want to go further, you can try pre-measuring your files with madMeasureHDR as explained here: https://forum.kodi.tv/showthread.php...406#pid2750406 Once your files are measured, you can experiment with some of the other tools mentioned there, including Soulnight's dynamic target nits tool.

I have been using HDR profile rules very similar to Manni's to match the target nits to the movie's measured AvgFMLL (Average Frame Maximum Light Level): if (hdr) and (AvgFMLL < 1) "General HDR" else if (hdr) and (AvgFMLL <= 100) "200 nits" else if (hdr) and (AvgFMLL <= 160) "225 nits" else if (hdr) and (AvgFMLL <= 190) "250 nits" else if (hdr) and (AvgFMLL <= 225) "275 nits" else if (hdr) and (AvgFMLL <= 250) "300 nits" else if (hdr) and (AvgFMLL <= 270) "325 nits" else if (hdr) and (AvgFMLL <= 300) "350 nits" else if (hdr) and (AvgFMLL <= 380) "375 nits" else if (hdr) and (AvgFMLL <= 550) "400 nits" else if (hdr) and (AvgFMLL <= 700) "425 nits" else if (hdr) and (AvgFMLL > 700) "480 nits" You have to measure your files for profile rules like these to work. This approach focuses more on preserving the dynamic range of the source, but it also gets the brightness/contrast right much of the time. I haven't tried to optimize them any further, only simplify them, but it does a decent job of selecting a curve most of the time. Manni's original rules also incorporate the AvgFALL and I removed that bit. This all could become a moot point if Soulnight's approach to changing the target nits dynamically during the movie ever works smoothly.

If you are testing with the latest builds and still find the image is too dark, trying changing the output gamma in madVR. Even those with a display calibrated to 2.20 can sometimes get a better result by setting madVR to 2.40.
