Win8.1x64, Kaby Lake i5 7200U/HD620 : 3D-MVC-mkv
Quote:
with this setup I have realized that 40-50% of my MVC-mkv do work smoothly, which is already a big success (here also the Player can be closed in a normal way); but the second half shows mostly only a black screen; sometimes audio works, sometimes not; sometimes the player hangs after a short time (~30s); but always (whether it hangs or not) the player can only be closed via the Task-Manager; since the working/not-working files are muxed over several years I would exclude a muxing problem... here a statistics of such a file... the rendering times are extraordinary @madshi: I will send you via pm a link to 2 small 1 min samples, one working, one not; maybe you can identify what the difference is...; I will also send this to @Nevcairel, since I'm not sure where the problem really is...

@madshi - is there any way you can give us control over how the screenshots are saved? I'd really love for them to be saved as PNG files, and to have control over the type of JPG they are saved as.

So I'd love to have either PNG or level 12 JPG instead of what level is being used - that would really complete the thing I want to use it for.
How can one set what file type is saved, and at what level? Really need it now.

You then go on to say that personally for yourself you don't see a difference and that is fine. But you shouldn't say "should be better" without qualifying so as not to confuse users which may not know the details behind the scenes. Regarding your 3D issue, perhaps you should post about it on the bugtracker for a detailed record of the problem. |

Those with a true 10 bit panel and the ability to sent 10 bit to it will have the better picture though wont they as dithering is filling in data thats already there on 10 bit. My 3D is working, I just have the well documented FES problems so I want to stop using it, I cant get 3d MVC to work without FES, I just want to know if i'm wasting my time trying to get it to work as it just doesnt work without FES. |

what the difference between 10 bit and 8 bit? noise level
dithering is effecting the lowest bits the bit witch are already all over the place thanks to encoding and again are altered thanks to chroma scaling and YCbCr -> RGB conversation. so now you go and do RGB dither it to 10 bit and makes the lowest bit more inaccurate give it the GPU that go and convert it to YCbCr down scale it to half the resolution 4:2:0 (yes it has half the resolution of RGB) and hopefully dither it yet again which again adds noise to the lowest bits. but now the real fun guess what a display has to do to display an image. well it needs RGB guess what it is doing yet again... RGB 8 bit shines most with TVs that properly support 4:4:4 and on these TVs chroma scaler have a bigger impact on the image. RGB 8 bit can give you a more refined image while high bit deep can give you less dither noise with madVR and for not properly dithering renderer less banding. |

My display is 12bits from end to end (input to panels) and 10bits output produces a better result than 8bits, especially in HDR. This is with my nVidia set to 4K23 RGB Full 12bits 4:4:4, as per my sig below.

and no you don't need 10 bit for HDR with no question at all nearly all TV out there have a 8 bit panel and no banding problems.
ST2084 is created so it creates less banding in the signal but pixel doesn't work like this. pixel are run pretty much the same with SDR or HDR because the pixel are changing there brightness with the number of transistors active for each sub pixel. the problem with the real bit deep of panels is so bit that it is close to impossibile to test a panels bit deep with signal because a 8 FRC looks so close to a real 10 bit panel that the human eye and measurement device can't easily see the difference. test are so bad that even a VG248QE a clear 6 bit panel gets 8 bit a rtings even the specs say it is 6 bit... (and obviously visible to me with test pattern not real content) and AFAIK there is no 12 bit panel on the market at all (professional screens are 10 bit too)and a very limited number of 10 bit panels. if that'S the result you get feel free to sick to it. |

Can you tell the difference between 8-bit and 10-bit from madVR with ordered dithering enabled (with the GPU and projector settings the same)?

It gets a lot more complicated when you bring GPU drivers and TVs into it. Some need 10 bit input to trigger their HDR modes, in that case you need the GPU to output 10+ bits.
The point is that being unable to get madVR to output 10-bit is fine for image quality, even if you are watching 10 bit HDR, and 8 bit RGB or YCbCr 4:4:4 is better than 10 bit YCbCr 4:2:2 or 4:2:0 unless your TV isn't good with RGB or 4:4:4 input (e.g. does its internal processing in 4:2:2).
