The display needs to get this metadata from the player somehow, otherwise all bets are off. If you want to somehow manually do that through external hardware, go nuts, but thats hardly relevant for madVR at this point. Also, that still leaves the problem that I seriously doubt HDR is meant to be transferred over RGB, as there is a distinctly different conversion from YUV/YCbCr to RGB for HDR content, and any RGB converted without this would already be mangled and damaged. A PC cannot output content "untouched", since PCs cannot output YCbCr as-is through consumer hardware/software.

FWIW, I'm working on HDR playback as we speak. However, madVR will convert the content to use a normal gamma transfer function. I expect final quality to be better this way than sending the HDR content untouched to the display and letting the display do all the processing.

Will we get the option to use PQ gamma, or will this be a fixed setting in MadVR? Any idea when we might be able to test this? Which GPU/Driver/MadVR settings will you recommend re pixel format / levels? Let me know if you'd like me to beta test, I should have an X7000 in the next few weeks. Does this mean you're going to implement HDR support in MadTPG for calibration as well? That would be great!

I'm just guessing here, but it sounds like something that might happen.

Madshi are you using the HDR clips Manni provided as reference?
So the HDR metadata is inside the MP4 file and this is what we might expect in the future 10bit, 4:2:0, rec2020, 3840x2160, HEVC? EDIT: Playing a little with the HDR demos of Exodus and PI I can get a decent image setting the black level to -30 or so. It is probably too early to say but if I'd have to guess, I think that these particular demos are just expanded versions of the original and not scene by scene mastered. The blacks of the content seem to be somewhere in the middle of the range, but what about the lower range? How the HEVC HDR encoding utilizes the 10bit to distribute the shades and how the TV knows to decode that and engage certain light zones in certain brightness is still a mystery... What is the difference between the two versions of the same video on that site? One is called "Dynamic Mode"? Hmmm... One thing is for certain, all the shadow detail is preserved because it is in the middle of the range unlike in a blu-ray where it is the lowest and first few steps and are blocky. Together with the high bitrate this creates a very beautiful picture and many times smoother than a standard Bluray. After Madshi will do his magic on the new format, even people with standard 1080p rec.709 monitors will see a clearly better picture.

So how would I go about checking if the 25 Hz is true/native 25 Hz? This is the first time I've heard that 25 Hz might actually be 50 Hz. I don't understand why the TV would report 25 Hz refresh rate if it's actually in 50 Hz mode. EDIT: From the TV's manual (under "Supported Video Resolutions"): 1920 x 1080 - Display Format: 25Hz, Horizontal Frequency (KHz): 28.125, Vertical Frequency (Hz): 25.000, Clock Frequency (MHz): 74.250 Don't know if the above means "true" 25 Hz or not?

Reports if 50 or 25 Hz can vary on how interlacing is detected and if deinterlacing is activated automatically. Better check this manually, AFAIK it cannot be entirely perfect in all cases.

I wasn't talking about what the TV supports or will accept, I'm talking about what the TV will display. As nevcairiel says, "25 Hz" input is likely for interlaced but even if you could send your TV 25p content, it'll display it at at least 50 Hz. Likely more, especially if it's a plasma (mine does 100 Hz for 25/50p and 96 Hz for 24p).

We use our TV driven by PC so it acts like a monitor if you set it up like this, means you turn off every image processing feature that could modify frames. With my LG means: I have to set scan mode, turn off TruMOtion and turn on (!) RealCinema (it's for 24p content, don't ask why they distinguished it). Quote:
I have 1 problem about this version of the story: my LG is EU version, so it's officially 100Hz (probably it refers to an 50fps content and using TruMotion with it.) But: what would happen with a 23.976 fps content with it? You'll never get 50Hz, neither 100. So will it use 48??? (They states that it'll use 120Hz with the US version.) Either way, I think it doesn't matter if the frames are exactly doubled or tripled, we will get continous movement with it, without stuttering and there won't happen any deinterlacing on our TV. This is how I understand it.

Just wondering, if the TV specs say "Display Format: 25Hz ... Vertical Frequency (Hz): 25.000", shouldn't it be "50.000" instead then? Anyway, I just realized 29 Hz and 59 Hz are not listed for my TV after all, so I'll need to delete them from madVR's refresh rate list. Last edited by Uoppi; 7th December 2015 at 21:43. |

Listed where? In the manual or in you display driver settings?

Dropped frames on dark scenes
Hello.
I'm having strange issue I guess with MadVR. I have latest MPC-HC 1.7.10, latest MadVR, Lav filders, running on XP. I have a lot of dropped frames on dark/black scenes with not much going on. So, for example I'm watching Hobbit 720p (8GB mkv file) and everything is pretty much smooth but when movie finishes and Cast of characters scene starts there is a lot of stuttering and dropped frames. Also, I watched movie Circle (2015) which takes place in dark room with several persons in it, not much going on there, but I got a lot of dropped frames again, movie is barely watchable. Does anybody now what can be the issue with dark (and slow) scenes? |

Just added this profile to MadVR and i want to know guys if you think if it's correct. I just want to have 3 options in MadVR scaler options
1-SD (files lower than 720p), 2-HD (files up than 719p and lower of 1080p) and 3-FULLHD (files up than 1019p) I want these three options for all video files playback, do you think that with the next arguments i'd be able to achieve what i want if (srcHeight < 720) "SD" else if ((fileName = "*720p*") or (srcHeight > 719)) and (srcWidth < 1080) "HD" else if ((fileName = "*1080p*") or (srcHeight > 1079)) "FULLHD" Last edited by digitech; 8th December 2015 at 04:46.

Ah, good point - only in the manual.
Display driver however lists them all and that's where I initially copied them from into madVR. I guess I should leave the setting untouched then. (Seems like the manual lists refresh rates the TV can actually display at, while the display driver lists input rates that the TV can accept. Right?) |

in the end the TV has to display the frame it get at the time they get them and this timing is changing from GPU to GPU. |

As huhhn said, it can vary: e.g. I removed 23p and 29p and 59p from the list in madvr because these modes gave me less HZ than the corresponding video material should have (you can't create proper clocks with Ivy Bridge) and that would result frame drops. I just prefer repeated frames instead with 24p/25p/30p/60p settings.
