I read this online and it made sense, so I tested it and it's certainly a noticeable difference with motion. I have a Panasonic FZ-1000 OLED. Pick your fave panning scene.. If you have the new Suicide Squad there's a scene where it pans there near the beginning across the whole team after it breaks away from Savant, Peacekeeper's ass juddering across the scene was a noticeable tell.. Lol.

I use the PC for the odd browsing online and maybe the odd game too so my preference was 4:4:4 anyway but if the motion was that much better I was going to consider turning off Pure Direct. I just got to a point where I was like.. I don't like this panning performance any more, I'll sacrifice something to improve it.. And it ended up being motion resolution thanks to Smooth Motion's frame blending technique which when I had the Panny VT plasma I didn't bother with.

According to Vincent (hdtvtest), there's no judder free 23p with chroma 444 on any of Panasonic Oleds Huhn used to tell the same for other Panasonic models as well in the past, so it must be a feature rather than a bug. That's why Panasonic was out of question for lot of us...
I guess the best option is to use 59/60p and use smoothmotion or just turn off PureDirect

Reporting back, the RTX 3070 Ti seems to work fine under Windows 10 (21H1) after enabling Vsync for MPC-HC. It seems to have WAY more processing power vs. the GTX 1080. Render times are much lower with the same options/settings as the 1080.

[SamuriHL]

I'm sure it does. sigh.

[Stereodude]

I did notice that DXVA2 copy-back decoding has lower render times by a few ms for ~24Hz content (1080p & 2160p) than DirectX 11, but DirectX 11 is lower for ~60Hz content (2160p) by a few ms than DXVA2 copy-back. (All full screen content, so I'm not being thrown off by black bar detection / a reduced processing load.)

2160p60 is only 8-bit RGB output from madVR and 2160p24 is 10-bit RGB output from madVR so perhaps that's a reason why?

On a 2.4:1 1080p Blu-ray rip I ran out of things to turn up. Was running very high NGU sharp scaling to 3840x2160p24 and had ~15ms render times (DXVA-2 CB w/ black bar detection on).

15ms... Fans be like *gentle breeze*
NGU be like *I'm giving it all I've got Cap'n*

I have a regular 3070 FE and I still have to test how far I could push it. Might end up settling for settings that avoid wasting a hundred watts for unnoticeable improvements.

[el Filou]

It's nice to have confirmation the doubled float units of Ampere do indeed work well with madVR.
I hope they eventually release a lower power 3050 model for desktop at 70-90W, would make a nice upgrade for my 1050 Ti (if the prices finally get reasonable, of course).

[DMU]

Please explain the difference between the messages in the OSD madVR:
limited range (say upstream) vs limited range (best guess)
And what conclusions can be drawn from these messages?

[huhn]

best guess the upstream doesn't have the information.
says upstream means the file is properly flagged.

I wish. My HTPC is down again as some people know from the other thread. Between lack of being able to find a new card, money to actually buy one, and time to mess around with the whole thing, all I can do is drool. LOL Some day I will get my hands on a new card, be it a 3080 or a 40x0 card. I do miss madvr, though.....

I am having a problem with this video:

Video
ID : 1
Format : VC-1
Format profile : Advanced@L2
Codec ID : V_MS/VFW/FOURCC / WVC1
Codec ID/Hint : Microsoft
Duration : 1 h 11 min
Bit rate : 7 451 kb/s
Width : 720 pixels

Display aspect ratio : 3:2
Original display aspect ratio : 4:3
Frame rate mode : Constant
Frame rate : 29.970 (30000/1001) FPS

Scan order : Bottom Field First
Compression mode : Lossy

Stream size : 3.70 GiB (79%)
Language : English
Default : Yes
Forced : No

While using MPC-BE and madVR. It doesn't happen with VLC, for example.

The video is suttering. Seems to be dropping frames all the time. This is my current config (onboard video), 16 GB of RAM, SSD, Windows 10-64 bit:
https://www.displayspecifications.com/en/model/7d502176
https://ark.intel.com/content/www/br...-3-90-ghz.html

Trying at 4K@30 Hz.

I tried resetting madVR settings and nothing changed. I know this monitor needs a new CPU/motherboard/etc. and a GPU, but this is a 1080p small video and it should work exactly like the rest. What is different in this case is the 29.970 framerate, which apparently madVR can't handle. I noticed this issue with 60 fps content, however it's the first time I am seeing with 30. It must be some madVR setting or MPC-BE's.

Can you post a screenshot of madVR's OSD (ctrl-J) while the video is playing (not paused)?

[digimaster]

Hi,

due to bad color space management in an (old) LG OLED TV I need to create two Display Properties profiles: the first 8-bit if the video signal is SDR and the second 10-bit if the video signal is HDR . The problem is that when these profiles are created, the HDR signal is no longer sent to the TV (even if the profile is correctly selected and the OSD reports "AMD HDR"). It seems to be a bug. Any suggestions?

Here it is:

After a few seconds playing...

On Windows 10 it is good to set the present queue to 1 (definitely not above 3).

It looks like the decode queue is not full, this tells me the issue is before madVR or during the handoff to madVR, or at least that the decode is slower than expected. What happens if you run DXVA2 native in LAV Video?

[ryrynz]

I've actually set my present queue above 1 now on my 3060 and it's fine (currently 4) the only thing I've changed recently is the gpu scheduling option in Windows.
I've also changed the flushing options back and it's still fine with seeking too *shrug* XD

Things improved when I changed to 1

********
windowed and exclusive mode settings

- present several frames in advance: [Enabled] Uses a new method for presenting frames in advance instead of using a back-buffer queue.

- how many video frames shall be presented in advance or how many backbuffers shall be used: [8 or 3] The present queue, a final buffer in DirectX, after madVR sends completed frames to Windows. (here)

- when and how shall the GPU be flushed: [flush, flush & wait (sleep), don't flush, don't flush] To be able to display rendering times in the OSD the '... after last render step' must be one of the 'flush & wait' options.
***********

But it's still not smooth as it could be.

How can I do that?

The display is set to 30 Hz when the video is 30i (well, 29.97i) so it's being deinterlaced to 60p (59.94p) and therefore half the frames are being dropped because they simply can't be displayed. Display must be set to 60 Hz.
