I got a strange picture in D3D11 mode for Sony_4K_HDR_Camp.mp4. Other HDR files are displayed normally.

This appears to be a "bug" in LAV, but I'm not completely sure. At least it seems that LAV reports the HDR metadata differently when using software decoding vs D3D11 DXVA decoding. I have a detection for "invalid" HDR metadata in madVR which fires with LAV in software decoding mode, but not in D3D11 DXVA mode. I'll discuss this with nevcairiel.

Are you sure it's really 0.92.1? Did you replace "mvrSettings32/64.dll"? Maybe your browser gave you an old version of the zip?

Actually it *is* set to be always on top! However, in fullscreen, it's possible that the media player (or even madVR) might try to make sure that the video surface is always on top, and if multiple windows are on top, only one can win.

Only vertical back porch is applied but that results in 23.972hz.

Strange! I've just tested it here, and modifying the pixel clock works just fine here. Generally, the edit field is dropping back to the old value if interpreting your modified result failed for whatever reason. E.g. did you enter a "," for the decimal instead of a "."?

It briefly appears for a fraction of a second, then it goes away (I missed it initially).

EDIT: just to clarify, nVidia sees my display as Denon AVR, MadVR sees the Denon AVR, I tell it i's an AVR, and then I configure the JVC (Digital Projector) as being attached to the Denon. The OS only sees a Generic PNP Monitor, although for Audio it sees the Denon AVR, which is my HDMI Audio Out (Default). Maybe I'm having the issue because the display isn't connected directly to the GPU?

Hmmmm... I didn't test with an AVR. Does the "identification" tab have an EDID block in it? The display mode functionality requires the EDID information to be available.

If all else fails, can you try directly connecting the JVC to the PC? Just temporarily, of course.

1a. The panning shots seem more fluid with the smooth motion solution, is that correct ?

True 23.976hz and 60hz with smooth motion should look very similar, except that 60hz smooth motion should have slightly more blur and maybe a little ghosting. So true 23.976hz is definitely better. However, not all displays handle 23.976hz input correctly. Some judder that way. So it's possible that 60hz with smooth motion might look better in your case.

3a. As I see it, they work very differently. Can they work together ?

Yes, it's supposed to replace ReClock. I don't think there's any need to use ReClock, anymore, if the "custom modes" feature works for you.

Yes, if you're only interested in 23fps/24fps movies and if you use 60hz smooth motion, then custom modes are not of interest for you. Neither is ReClock.

The Sony sample has broken HDR metadata, I wouldn't worry too much about it.

I'll donate for sure once the version 1.0 is out .

Glad to hear that!

- Using the latest 385.28, there is an improvement re HDR in 0.92.1 as I can now get the HDR Metadata (MadVR set to pass through / send metadata) but the display doesn't switch to HDR automatically. Not a problem for me as I disable the JVC mode and switch manually to a custom mode, but I thought I'd try and let you know.
- The new 10bit path without FSE works great. That's really nice as on the JVCs FSE led to a few seconds black screen every time you used the player interface, for example, to select audio/subtitle track. Hopefully it will be possible to do without FSE for 3D too at some point.

Nice!

3D doesn't work for you without FSE? I'm pretty sure it worked for me, the last time I tested it. Although Nvidia is more picky than AMD and Intel. E.g. IIRC, it works with Nvidia only on the primary monitor, but with AMD and Intel also on secondary.

I couldn't see such in the tool.

I don't really know. I'm not even sure if the custom modes generally affect D3D11 FSE or not. D3D11 FSE is somewhat "special".

Is there a way to reset If I exit MyMovies, the display returns to 4K23 and all is fine again. None of this happens without a 1080p23 custom res. As there doesn't seem to be a way to revert to default timings, I'll wait for a fix for the custom res tab to see where that gets me.

Don't know what to say about that.

Yes, but I did implement detection for broken HDR metadata in madVR, and it works when LAV is using software decoding. But somehow the D3D11 DXVA decoder reports the broken HDR metadata differently, so my detection fails. There must be a reason for that?

Here's my code:

  if ((m_HDR.white_point_x != 0.0) && (m_HDR.white_point_x != 1.0) && (m_HDR.max_display_mastering_luminance > 1.0))"

It seems one of these conditions doesn't apply with the D3D11 DXVA decoder?

HEVC 10bit works fine now with LAV DXVA D3D11 and madVR with AMD Polaris (Win 8.1 here).
Thanks madshi and nev.

I suppose it depends where you implemented that? Because in the D3D11 case I implement the IMediaSample, so if you have it in there, it wouldn't work.

Otherwise, the exact same data is being fed to you.

It reports a value of 1 nit, which seems to match the broken data.

Yes, there is a (populated) raw EDID data. I'll try a direct connection with the PJ and will report back.

No, for me 3D only works with FSE. I tried without and I get weird colors/corrupted picture without (although as far as MPC-BE is concerned, it "plays"). I might try again without a custom 1080p23 timing, I can't remember if I tried before of after attempting the custom timings, but I think it was before.

It would be great if the final tool (custom res tab) allowed to go back to the default timings after further testing. It's not because there is no crash that there cannot be a reason to revert we will only come accross later.

You should be able to go back at any time by clicking on the custom mode, then pressing the "delete" button. At least that's how it's supposed to work.

how about some even more advanced test.

like frame skipping: https://www.testufo.com/#test=frameskipping

or a test to check if a TV has a properly working 23p mode.

you use the same test and check the brightness of the squares. it should be very obvious on a TV that is doing a 3:2 pullup.

Thanks, I wasn't sure it would do that or delete the mode, so instead, I did a clean install of the drivers to make sure I started with a clean slate.

Even with no custom res from the standalone experimental tool, the tab was missing.

So I connected the PJ directly to the GPU momentarily, and the tab appeared, so it looks like it doesn't like it when an AVR is in the chain, even if the AVR reports a populated EDID block.

I also tried 3D without FSE without an AVR in the chain and without any custom timings, and it definitely doesn't work here. The picture isn't corrupted/with weird colors as earlier, but it's 2D (no 3D at all) even if the OSD reports 3D windowed.

Hope this helps!

[mitchmalibu]

Thanks for the release madshi.

I did the first optimization run for the 2160p23 resolution. Everything went fine but when using the resolution and the same video file, windowed fullscreen reports a frame repeat every 5 minutes and fullscreen exclusive reports a frame repeat every 65/70 minutes. Clock deviations are the same.

Am I missing something ?

[JarrettH]

Edit: Now understand you need to switch to 60 hz before modifying 59 hz otherwise you can't customize a "standard mode" refresh rate.

madshi, thanks for this new version

I have a Dell U2417H and modes 50, 59, 60 under the status column are listed as standard modes (the OS reports them). When playing a 23.976 video madvr reports "display 59.933 hz" and "composition rate 59.940 hz". Since I already have these modes listed and not missing, should I further optimize the 59 hz one or is it already perfect? The EDID for 59 hz "results in 59.93939 hz". Just now I played a 23.976 video for 40 minutes uninterrupted resulting in 1 frame repeat every 6.50 minutes.

What do you mean by a 59p video? I've never played a 59 fps video in my life :P



Thanks for clarifying.

I'm trying this, but I have a 4K TV with profiles and a 1080P monitor, however the custom dialog only appears for the 1080P monitor, and not the 4K TV (where it would count), with profiles, I see it appear and then disappear just as fast.

Guys now that Im finally on Adaptive and have everything working perfectly I was wondering about dithering for 4K upscaling BDs...
I have the 1080Ti card and all my rendering times are now very very low.
These are my settings:
Chroma upscaling NGU sharp high
Luma upscaling NGU sharp high
render times 15.20ms

Dithering is set to Ordered dithering,
Should I use something higher like Error diffusion 1 or 2? since my render times are so low?
If so which one produces the best image?

[Asmodian]

There is no "best" when it comes to the two error diffusion options. I have been a fan of ED1 on my recent IPS monitors, on my older one I prefered ED2. However, on my new OLED TV I prefer ordered dithering, after a lot of testing. I didn't expect it but I have to believe my eyes.

You need to open it on the TV itself.

You need to open it on the TV itself.

I've tried disabling the 1080P monitor (so everything opens on the TV and also setting to the primary in display properties, again so that madvr opens on the TV. On another system with 4 monitors all monitors show up when I select them no matter which it was opened on, but on the HTPC, I can not get custom to display for the TV, only for the monitor, it might have to do with profiles, but I have 8 and do not want to loss them unless there is no other choice.

Thanks,
ERIC

[Asmodian]

You can backup settings.bin and then reset to test it. I am not sure, it shows up on my TV but I don't have any profiles for displays.

[AngelGraves13]

Getting random crashes of madvr and lock ups of MPC-HC with the new madvr.

Also, deinterlacing doesn't work with the new DX11 renderer.

Using NGU for Chroma causes it to crash as well. Didn't try the upscaling as I never use anything but Jinc for all my scaling needs.

[QBhd]

Similar here. PotPlayer + madVR + LAV.... Files in play list play fine, but the player crashes (sometimes it's madVR) as soon as it moves on to the next file. I had to get up off the couch and close everything and restart playback again manually for the next file. I rolled back version and all is working fine again.
