Calibration and Sharpness Setup are very important here

Clarisimo!
So, when madvr says 10 bit in exclusive mode, what does it mean?
It mean that last data which user mode software pass to driver is 10 bit. No more, no less.

How should I configure madvr/lav in order to perform HDR-->SDR conversion and leaving BT.2020 untouched?

I have a JVC projector and a popular method of watching UHD is to let Panasonic UB700/900 do HDR-->SDR conversion with BT.2020 passthrough with the help of the HD fury/integral. I am basically interested in doing the same thing with Madvr since I now have HDR content on my HTPC. I am thinking this should be possible?

This post lead me to think about something: I've got a 4K TV and madVR set in relation to it.

Recently I changed video card (upgraded to a GTX1070) and used again dispcal to calibrate the TV, I set it to 2.4 gamma with 6500K white point... question is...should I recalibrate it to BT2020?

Now madVR is set "calibrated BT709 with gamma 2.4", if I change it to BT2020 I see that the video is like losing colours, with DCI-P3 I see it like a middle way, while BT709 is the one more colorful (even if with some video sometimes faces look a bit too red but not with all of them so I guess is also related to the way has been shooted).

Can anyone give me some opionion about this? Please :-)

thanks !

this means that Madvr can never match or exceed the quality of the native TV player?

Be careful, you cannot equate quality only to bitdepth.

For example, upscaling chroma with bilinear but preserving 10-bit is not better, IMO, than using jinc, NGU, or NNEDI3 for chroma scaling and dithering to 8-bit.

Actually, for display 10-bit is fairly unimportant if the dithering is high quality. Dithering doesn't live through compression so 10-bit is very good for source material and processing in >8bit is very important so errors don't build up but for final output and display madVR's 8-bit output with ordered or ED dithering is indistinguishable from 10-bit.

The best you can do is 60Hz 4K 4:4:4 8-bit, or if you really want 10-bit for some reason its down to 4:2:2.
Hi nevcairiel (or others)

Source: UHD HDR bluray remux

Would you recommend 60Hz 4K 4:4:4 8-bit, or 60Hz10-bit 4:2:2 or something else?

Thanks.

I would strongly recommend 4:4:4 8-bit, madVR's chroma scaling is great and 10-bit isn't important with good dithering.

I don't really like the temporal dithering used by FRC displays but madVR's spatial dithering is excellent.

Does anyone know what kind of scaling can be done by a GTX 1050? I'm interested in that card for the 2160p60 10b HEVC decoding, although I'm not sure whether the extra VRAM of the 1050 Ti would make a difference for madVR?

The RAM isn't too important for madVR, you can use smaller buffers, but the extra cores/shaders can allow the use of the higher end scalers, etc.

A Spatial noise Patern is indistinguishable from a Temporal Approach ?

No noise at all the clear Signal that is what you aiming for neither Temporal Noise nor Spatial Noise

But you never gonna see the benefit unless you see it on a total 10 bit Chain in and out in Motion

And you would need to see the Processing side by side so MadVR vs TV Chip (Signal Chain) anyways (did you do such a test with a 2016 TV out of the Premium Line ? )

And internally you never do any PP in the native 10 bit but above it same the new TVs seem todo Sony Processing it seems upto 14 bit internally (depending on the price you willing to pay).

This Scene of course will band extreme in 8 bit and the closer you are calibrated the more visible it will become and a simple spatial patern wont rescue you here in motion.

Not sure where these 1 Pixel error comes from in this Demo you can see very small red Pixel in various frames maybe the Sensor had issues, GPU Processing or left Path Tracer artifact :)

Might sound redundant but could it be possible to add a profile management layer on top? Currently my use of profiles is ridden by nature of source (res, fps, etc) and display (monitor or TV), the issue is that more and more often source content defines the settings to be used, specially when comparing those for anime or real life content, in this regard conditional profiling doesn't apply, and profile hotkeys are disabled since I already have some conditionals...

So you like 10-bit 4:2:2 instead?

madVR outputs RGB so having the GPU convert to YCbCr and downscale the chroma has always looked worse to me then the VERY subtle noise from dithering in 8-bit. Most people cannot see a difference between dithered 10-bit and dithered 8-bit even with specific test patterns but blurring the chroma is (relatively) obvious in specific situations.

Of course 10-bit is nice for the reduced dithering noise but only if you can maintain RGB at the same time, IMO.

I can distinguish temporal from spacial dithering, pixels have a minor "shimmering" to them which is more noticeable to me then the static noise from madVR's dithering (I like madVR's dithering without color or motion).

Edit: Some TVs might do as good a job at chroma upscaling as madVR, do all processing in at least 14-bit, and maintain 10-bit to the panel but at the same time you cannot say quality is only 10-bit v.s. 8-bit.

Yes i like the idea of 10 bit 4:2:2 and Samsung at least seems to officially support it on their 2016 Platform not sure about Sonys state here very few real useful official information on Sonys side.

The thing is as nice as it sounds to put the PC to the TV it is blasting inefficient on every side just for that small gain especialy with NGU wasting so much energy that is sorry crazy.

All TVs currently are Highly Efficient ARM Platforms Partly with their own Processing SOCs and you Put a PC to that todo Chroma upscaling with a Discrete GPU ?

If you use that TV as a PC Monitor you should take advantage of this and not use the PC at all anymore for Media Playback only for those that ARM System is to weak for or doesn't support, and merge both in a efficient way.

I was wondering if madVR has ever considered including DLP Checkerboard as an output format?

I have an old Samsung DLP that will do 3D if the input is in Checkerboard format. The MVC builds of Kodi can actually do this, but it currently has some trouble with some of the MVC MKVs that I've made. I know that madVR handles these MKVs just fine, because if I set madVR to display side-by-side, it shows the files properly decoded. madVR just doesn't do DLP Checkerboard output. I'd prefer the simple combo of madVR with a simple media player anyways. :)

I know that this is an old display. I would just like to use it if I could.

There was a thread on Kodi's forum when this was asked about a few years ago, before Kodi implemented it. The developer of Bino3D chimed in, as they had implemented DLP Checkerboard in Bino3D. Maybe the information in this thread would be useful:

In my case, Kodi isn't properly displaying the MVC MKV files that I have. (I will attempt to work with the Kodi guy to get that problem resolved, but that's a separate thing.) I know that madVR can decode the files correctly because it can display them side-by-side.

Having madVR have the ability to output to DLP Checkerboard would open up madVR to be used in this instance in all the places that madVR can be used, which is a considerable benefit to madVR.

Thanks.

Yeah the 1050 Ti is more powerful but I'm not sure if the difference is enough to actually allow any better madVR settings to be used. The price difference is pretty big - a jump from £110 to £140.

True but unless I'm totally out of the loop, you can only use madVR within Kodi when using DSPlayer, which is no longer updated. It also doesn't work properly with live TV (at least when using the MediaPortal TV Plugin), whereas using the default Kodi video player works fine.

if you want to scale to UHD you will need to buy a 1050 ti i don't see a problem with the 1050 for FHD.

you need more than 2 Gb of Vram for UHD.

I see. I'm not sure whether to just get a 1050 for HEVC HD stuff now and upgrade again when I eventually upgrade my TV, or to just plump for the 1050 Ti and maybe have forward compatibility.

2nd January 2017, 19:48

i would get the 1050 ti or nothing at all.

i have a UHD TV for over a year and a GPU that can decode HEVC too and i never needed it.

These were questions about madVR... I am not sure what you are arguing; HTPCs aren't worth it in general?

The little ARM computers in TVs are ok but I much prefer Zoom Player wth madVR, NGU, 3DLUT (i1 Pro2), and ED dithering. It takes more power then using the TV's soc but it is higher quality and much easier to control. My Titan X (Pascal) keeps my room nice and warm. :p

Adding to my question on profiles (http://forum.doom9.org/showpost.php?p=1791601&postcount=41829) (I like NGU for SD real life content, but not on anime), I wanted to address a few points.

Overall I like the new GUI, yes some setting freedom is lost but the layout makes more sense. To note a few things, next to NNEDI3 and NGU (only doubling, quadrupling) or something similar should be remarked, so the following settings makes more sense. For instance NNED3 is capable of quadrupling but the setting still says (algorithm to use after "doubling"), it confused me at first and I am a long time madVR user that came back after a few months off.
Also the setting "200% super sampling" looks out of place, I personally don't find how super sampling a 1080 source can be improved for viewing on a 1080 display, all while we already have 200% (doubling) HQ upscalers for sub-1080 sources.

Another point, many graphs don't update accordingly (reconstruction upscaler on the various variations; soft, sharp...)

And a question, what is bicubic50, 60, 75? How does that translate to Catmull-Rom (0.0,0.5), Robidoux (0.3782, 0.3109), Mitchell-Netravali (0.33,0.33)...

@Asmodian, thank you! you quite keep things up to date. I guess arbitrary settings are not possible like Robidoux or that negative "b" Didée suggested back then.

I did some comparisons with my old default (NNEDI3 based), and my (now decided) new default using NGU, they are all transcodes but improvement is superb, even when I'm never for ultra sharp plastic-like results, but NGU does things in a very subtle and smart way, only on very SD content (mostly sub 480p) a softener must be applied, or something like NGU-low (softer) while we wait on what NGU quadruple can deliver. I'm not too fond on relying in post-processing (soften edges, etc) to fix things that can be handled before hand. btw I also second the option for calling madVR settings on a hotkey.

You misunderstand me for old TV Platforms MadVR is a good solution but im not sure if it still will stand up vs 2016/2017 Platforms.
We might getting into equal quality results this year on the Processing side for a much bigger userbase.

Especially the "It is higher quality" is questionable if that will still hold up.

And yes a HTPC depending on the Format needed for consumption only is becoming more and more useless and inefficient for the AVG mass market.

And 10 bit is super important and surely no small step finally leaving Hollywood to end users.

MadVR is super useful i agree on the control side of things for Windows PCs and Madshi did a awesome job here, combining things and now presenting his own approach with NGU.

Any chance of adding a new option to allow different profiles for different resolutions? So for something intensive like 4K/UHD playback it allows you to choose a simpler scaling method (or no scaling at all) and will auto switch to that profile upon detection of that resolution? I have found at least one 4K video I cannot play using the settings I usually use for 1080P material without tons of dropped frames even on my overclocked RX 480 and I7 4770K (LG Chess UHD HDR demo). I have to back off to really simple scaling for that clip to play smoothly.

Huh is it losing Hardware acceleration does it accelerate it at all ?

Is it only this 4K HEVC Demo that collapses with your scaling chain in MadVR on your RX480 ?

But yeah it's the most complex one currently out of Atemes Titan

Would be nice if you could push your RX480 Decoding result of it (without MadVR overhead) in the HEVC Decoder thread we have no information on that one yet.

Also the setting "200% super sampling" looks out of place, I personally don't find how super sampling a 1080 source can be improved for viewing on a 1080 display, all while we already have 200% (doubling) HQ upscalers for sub-1080 sources.

I find it fantastic to reduce aliasing while retaining all the details, and to also reduce dark halos. The result is sharper too so it is a must have for me.
I use it with Bicubic150 AR for downscaling after doubling with NGU for luma, and Lanczos3 AR for chroma doubling (impossible to do that in new versions unfortunately).

One more post on DLP Checkerboard...I've found that the other program that I was using is really kind of unreliable: we attempted to watch a 3D movie with it, and it had several issues, including complete crashing. I loaded the same file up in MPC-HC using madVR showing side-by-side, and it works like a charm. Not that I can _see_ it in 3D like that, but I was testing to see if there was another issue causing the crashes. madVR really seems to do a much better job with MVC.

I suspect this is way low on the priority list these days, with HDR and 4K being more interesting...I just thought I'd ask. :)

Thanks.

MPC-BE; LAV-Filters; xySubFilter; madVR;

give Problems with Subtitles (idx/sub) and cropped h264 Video packed in a MKV:

I have chosen in madVR (under "zoom control") to move the subtitles to the bottom of the screen/window;
but in the case of the cropped Video the Subs remain always within the activ/Video area (I'm in full Screen, not windowed);
also in xysubfilter the "override Placement" Option does not allow to leave the active Video area;

is that a bug, or am I missing something?

Thanks

meanwhile it is clear that the MPC-BE internal subtitle filter can move PGS outside the Video area of cropped Videos (probably also text based ones) but not idx/sub...

LAV/xysubfilter/madVR can neither PGS nor idx/sub...

sorry, if I sound rude; I know everybody is doing this in his spare time, for free... but on the other hand...
I think, with all the discussions about fancy scaling options for equipment where there is no realy matching content available yet (from my Point of view : "early adopter" problems), the basics are losing focus:
things like normal subtitles and 3D-subtitles should work first before one moves on to the next Level...

So, apparently, AMD is developing a framework called Freesync 2 (http://www.anandtech.com/show/10967/amd-announces-freesync-2-improving-ease-lowering-latency-of-hdr-gaming) which doesn't seem to have much to do with variable refresh rate and has more to do with allowing PC applications to get information about the capabilities of HDR displays and then use this information to directly drive the display with HDR content. That sounds extremely relevant to madVR, though just like G-Sync and Freesync, the biggest problem is getting displays other than gaming-focused PC monitors to pick up the standard.

Asmodian

I am not sure it is too relevant, low latency tone mapping doesn't help with video playback because latency isn't an issue and we already have fast HDR tone mapping with madVR anyway.

Being able to query the monitor for its tone mapping information might be nice, if it was in a form madVR could use, but it would not be as accurate as using a 3DLUT for HDR tone mapping. Also madshi doesn't seem to like implementing proprietary APIs and Freesync 2 capable displays will always be rare. :(

Edit: If this does become a good standard for an application to be able to get the display's HDR metadata it would be very good, automatically rendering into the display's native color space sounds very nice. There isn't anything else like this anywhere as far as I know.

This makes no sense... why is everything doubled up? I think it's time to clean up your profile script

QB

Edit: I cleaned it up for you:

if (deintFps < 26) and (srcHeight < 541) "540p25"
else if (deintFps < 26) and (srcHeight < 721) "720p25"
else if (deintFps < 26) and (srcHeight < 1081) "1080p25"
else if (deintFps < 26) and (srcHeight < 2161) "2160p25"
else if (deintFps < 61) and (srcHeight < 541) "540p60"
else if (deintFps < 61) and (srcHeight < 721) "720p60"
else if (deintFps < 61) and (srcHeight < 1081) "1080p60"
else if (deintFps < 61) and (srcHeight < 2161) "2160p60"

BTW.... the easiest and simplest way of doing scripts is to start low and go high with the "less than" operator. And it is best to start with frame rate. As you can see from my scripts it all goes up up and it is easy to insert new profiles if they are needed. It's all about understanding how logic works :)

While it makes no real difference I like:
if (deintFps < 26) and (srcWidth <= 960) and (srcHeight <= 540) "540p25"
else if (deintFps < 61) and (srcWidth <= 960) and (srcHeight <= 540) "540p60"
else if (deintFps < 26) and (srcWidth <= 1280) and (srcHeight <= 720) "720p25"
else if (deintFps < 61) and (srcWidth <= 1280) and (srcHeight <= 720) "720p60"
else if (deintFps < 26) and (srcWidth <= 1920) and (srcHeight <= 1088) "1080p25"
else if (deintFps < 61) and (srcWidth <= 1920) and (srcHeight <= 1088) "1080p60"
else if (deintFps < 26) and (srcWidth <= 4096) and (srcHeight <= 2160) "2160p25"
else if (deintFps < 61) and (srcWidth <= 4096) and (srcHeight <= 2160) "2160p60"

Sometimes things I watch are very cropped so I want to use both dimensions when picking a profile. Resolutions fit together more then frame rates for me... not sure why. :p

I also tend to add an else "fast" at the end. If madVR hits the end of a profile script without picking a profile it uses the first profile in the settings menu, which is sometimes not what you want with a video that deinterlaces to 120 fps. ;)

A little help here. :helpful: What is the best frequency to watch 23,976 fps movies? I have these options on my TV + NV: 23, 24, 25, 29, 30, 59 and 60 mhz. (And how should I setup reclock?)

Gracias!!!

Asmodian

4th January 2017, 16:41

Out of those, 23. 23 is actually about 23.976 Hz.

Not MHz, that is a million times faster than the refresh rate. ;)

huhn

4th January 2017, 16:42

with reclock it doesn't really matter if you are using 24p or 23p.

reclock default setting should be fine.

23p is 24000/1001 same counts for 29p and 59p.

jaja yes, Hz... and reclock is necesary?

sneaker_ger

4th January 2017, 16:57

Necessary? No. If you have frame repeats/drops because of a slight fps mismatch it can fix those. But even without ReClock you may not have any or only very few (e.g. 1 every hour) and you probably wouldn't notice anyways.

Huh is it losing Hardware acceleration does it accelerate it at all ?

Is it only this 4K HEVC Demo that collapses with your scaling chain in MadVR on your RX480 ?

But yeah it's the most complex one currently out of Atemes Titan

http://i1.sendpic.org/t/uy/uy2ONC28q4NfaBANa2r82hw4SyV.jpg (http://sendpic.org/view/1/i/kbOlJXnoiYyTezTj0OXLKzykIhp.png)

I actually wonder how Samsungs Hardware Decoder handles it :D

Would be nice if you could push your RX480 Decoding result of it (without MadVR overhead) in the HEVC Decoder thread we have no information on that one yet.

I will try and sort something :)

Here ya go.

Does using de banding, as it softens the banding, can it also soften the image?
Do most use it or not?
What are the most preferred levels?

baii

4th January 2017, 21:09

if you want to scale to UHD you will need to buy a 1050 ti i don't see a problem with the 1050 for FHD.

you need more than 2 Gb of Vram for UHD.

Have a Rx460, don't seem to have much problem with ngu 1080p to 4k.

By the way, was there a update in madvr or dispcal that made 3dlut calibration "cheaper" to run?

Asmodian

4th January 2017, 21:12

Debanding on low does very little softening of the image, I use low/low by default on SD material and med/med if there is still banding with low/low. Only high has too much smoothing to use all the time (high is only useful for fades). I usually don't run debanding at a higher strength for fades because fade detection triggers on more often then I would like and I don't have an issue with banding during fades.

23 hz is the same as 24p of the tv?

Sometimes, the TV will probably report 24p when in both 23Hz and 24Hz modes, but with Windows 24 Hz is usually 24.000 while 23 Hz is 23.976.
