Another idea is to lower your buffer sizes, UHD buffers take up a lot of RAM. Try something like 8 CPU and 6 GPU buffers.

Hi Madshi,

Thanks for updating 0.92.17. I found a problem related to a HDR passthrough issue with my 3DLUT file. I'm using Windows 8.1 platform, with NVIDIA GPU GTX960 and GTX1070 on two machines, using HDMI 2.0 to my TV with HDR ability.

It was working well on 0.92.16 and earlier versions. But on 0.92.17, it's not working on both of my machines.

Basically the problem is, when I choose "tone map HDR using external 3DLUT", it seems madVR fails or "forgets" to send metadata to my TV (which doesn't trigger HDR on).

However, for "let madVR decide" and "passthrough HDR to display", these two options will still "trigger" my HDR on my TV. If I switch to "passthrough HDR to display", the HDR will be turned on, as expected.

Once the HDR is turned on during the playback, if I switch from "passthrough HDR to display" to "tone map HDR using external 3DLUT", the HDR is still on. That's why I guess madVR "forgets" to trigger HDR with 3DLUT like before.

Actually, make sure its set to DXVA2 (Native), and that madVR reports DXVA in the OSD. Copy-Back is too slow on Intel GPUs for UHD.

Shouldn't this be impossible, according to huhn?

Hi madshi,

The new HDR tone mapping settings page doesn't include Output video in HDR format check box when using tone map HDR using external 3DLUT.

Thanks

Guys, I'm getting confused with all the different posts on the subject.

I have a Sony X940E which has a 10-bit panel. Using my Nvidia card (1050), which Output format should I be using?

Right now I use 4k 23hz 8-bit RGB FULL.
Should I be using anything else? (like 12 bit RGB, 422/444/420)

Also, should I use the same for both SDR and HDR?

Many of us match refresh rates because everything we play is not just one native rate. Also Windows and GUI's for programs such as front ends are designed for 60Hz. So, while a permanent setting of 23Hz might match any 23Hz titles you are playing, anything else will not match and certainly your Desktop and GUI's won't be optimal. If you are matching rates and end up with a UHD 23Hz title, great. RGB Full at 60Hz is what I use and match refresh rates at 12bit. RGB is preferred because that is what a PC uses unlike a dedicated set top player. So, RGB from the GPU output avoids any extra conversions when a PC is used. Unfortunately, nVidia does not offer a 10bit RGB setting. (this was one of 3 fixes I had hoped madshi would consider mentioning to his nVidia contact when/if appropriate) So, you have two choices: Use 12bit. It will dither down to what ever your source is. But, in the event your display does not handle 12bit properly, even dithered down, it may introduce 'banding'. Also the newer drivers can't even survive a reboot if this setting is used so if you do... you'll have to remember to reset it or use driver 385.28 before the problem was introduced. Or, select 8bit, and avoid the issues at the cost of nothing you will likely notice. SDR vs HDR: SDR usually always uses 8bit and HDR 10bit. You need not change any settings HDR vs SDR for refresh rates. Regarding your 23Hz. Understand, some displays are 60Hz max. Some 120Hz and beyond. Folks with 60Hz displays often desire playback at 60Hz used in conjunction with a smoothing algo like that included in madVR. This is to avoid 3:2 pulldown which introduces judder. In my experience, even with smoothing algo's, there is still some judder. Ultimately, my display is 240Hz interpolated. I can have perfect multiples of refresh rates and am not limited to 60Hz so I can match rates without any pulldown or mismatch of rates coupled with a smoother. You need to know your own and select your optimal settings to match your environment.

Thanks for the kind reply, Asmodian and Nevcairiel.

1. Both DXVA2 (copy-back) and DXVA2 (Native) don't work.

2. D3D11 works if Hardware Device is set to Automatic, but fails if HD Graphics 620 is selected.

3. Lowering the queue size in the rendering general setting has no effect.

4. GPU usage hits the 90s, while CPU usage stays in the 20s.

5. Render and Present queue stay low.

6. About 7000 dropped frames and few hundred repeated frames reported for the 4min clip. Is madVR rendering the clip at 29fps?

Many thanks for your kind assistance,

Fullscreen Exclusive (OSD wise anyway) seems to be working again with Windows 10 1809, they must have fixed what they broke.

Shows 60 Hz in the composition rate, although its 23.976, had that before if I remember.

Yes, looks like you just select Light/Dark for App mode and it applys it to everything. Not a fan myself tbh.

Hi, I have an issue with videofiles contains:
Format : HEVC
Format/Info : High Efficiency Video Coding
Format profile : Main 10@L4@Main
Codec ID : V_MPEGH/ISO/HEVC

The videoplayer stays black, only audio is running.

In this state, I am also unable to see information with Ctrl+J.

What I have found out: other videofiles like
Format : AVC
Format/Info : Advanced Video Codec
Format profile : High 10@L5
are running fine.

So currently I use MPC-HC 18.2.4, LAV Video Decoder 0.72.0.15 and madVR 0.92.17. No Hardware Decoder is used in LAV settings.
When I change MPC-HC to Enhanced Video Renderer, the HEVC files runs fine.
So what I have found out is: the current setting is "chroma upscaling: Bilinear" (done by GPU). When I change this setting to Cubic (custom pixel shader code), the HEVC runs fine with madVR again.

I can change it when the file is currently playing. The video is black -> I change to Cubic -> video is visible -> I change to Billinear -> Black. When I open Ctrl+J during Cubic and change back to Billinear, the image freeze (but audio still playing).

Currently I am able to verify the issue with 2 old laptops, Intel Core i7 620LM with "Intel HD Graphics" and another with Sandy Bridge generation.

I changed on my Desktop PC the setting also to chroma upscaling Billinear, but the files run fine there (980 Ti NVIDIA GPU).

So... the issue is maybe in combination with some (old) Intel GPU, or the madVR settings in whole combination. I would like to share you my madVR settings to veryify the issue, but I can't find the location of the setting file and can't find any export function. Can you tell me?
If there is also some more information missing, just ask.

Which D3D version you using? Try 9 if you're using 11 and the other way around, also try using default settings (use the batch file)

Microsoft have pushed out their semi-annual Windows 10 update (1809) today. Anyone noticed any bugs with MadVR?

If you are talking about general settings -> "use D3D11 for presentation", it doesn't make any difference when I un-/check this option. It stays black.

@morku: try reverting to LAV 0.71, it solved my problem of missing hardware decoding for 4K, as I reported on the LAV thread

@dbcooper: I got upgraded to 1809, no trouble so far

Try unchecking Rendering/General Settings/delay playback start until render queue is full.
