madVR - high quality video renderer (GPU assisted)

I got alot more screenshots, from different videos, same results, either i mess up something, or it DOES NOT work as well when you use it for 4k playback/videos on 1080p monitor.

I believe you were using Bicubic75 for downscaling? That would explain it. Other high quality renders might use something very similar to madVR's Bicubic75 for downscaling but nothing else uses anything as good as SSIM or Jinc.

Edit: I should add that madVR's greatest strength is SD at 1080p or 720/1080 at 4K. SSIM is very impressive but other than that it is hard to be obviously better when downscaling, downscaling looks pretty good even with the old fast methods like bicubic or even bilinear.

What's about DXVA downscaling, is that good or bad in comparison with Jinc/Bicubic/Bilinear..., my iGPU can only afford DXVA downscaling of 4K

[Asmodian]

DXVA is usually similar to Bicubic75 or perhaps Lanczos 3. It is dependent on the GPU hardware and its drivers. Jinc and SSIM are significantly better than any DXVA scaling.

Q: I noticed that sometimes madVR reported "dropped/repeated frames per time" but now I don't see that feature on the HUD. On what does it depend on?

Hrm I seem to have triggered it when I changed to 75Hz. Does it not support odd frequences?

update: it's unlikely to be that though since I had seen the feature before on other ones.

Hi, are there any tricks to searching on this forum, its no surprise that stuff comes up over and over again as you just cant search for it. Here is an example. If you want to search for 3D issues, "3D" is too short, "3D MVC" is unrecognized or too short, "3DMVC" only brings back 3 results. Same problem with FSE, 3D FSE etc.

Finally moved to win10 fall update with nvidia 390.65 (gtx 1080). Everything works well, HDR switches automatically, 3D works properly (only on fse though). Have a weird minor problem, my mouse pointer disappears when I am watching 4K+HDR on fse. I dont want to disable fse as 3D definitely needs fse on my setup. Not sure if its something to do with madvr or in win10.

I have tested this problem on both my htpc and gaming pc. Both are on win10 1709 (fully updated), nvidia 390.65 (gtx 1080). MPC-HC(x64) + madvr (0.92.10).

I dont have mouse pointer trails enabled.

You can use profiles with MadVR and only have FSE on with 3D. That's what I do.

To summarise some of the responses you may/have receive(d):

• Some users don't like the delay when mode switching between different refresh rates
• Some users cannot achieve (or want to put in the effort to achieve) perfect refresh rate matching
• A lot of displays have "quirks" when using 23/24p refreshrates (downsampled chroma, cannot disable TV processing, internal judder in TV processing pipeline)

Regarding the latter, you'll also find a lot of users are willing to accept the quirks of the TV for temporal resolution/display BFI/etc.

You'll need to get a screenshot without RDP, and it may be useful to get a general idea if there's a trend in what the numbers are showing (e.g. presentation glitch number rises, or XYZ queue drops every Y often over a period of time where you see the issue occurring multiple times).

There have been reports of people getting frame drops when pushing their GPUs to 90+% usage. One thing to keep in mind that since madVR uses multiple components of a GPU, the core GPU utilisation may not be a true indicator of what components are at their max utilisation. Testing and checking frame rendering times and frame drops is the only way to know for sure if you are over the max capabilities for your card.

At first glance there's a couple of differences that stand out to me, but I'm not really one to pixel peep. If you can't see a difference then there's nothing stopping you from using VMR9. No one is forcing you to use madVR, but at the same time, you likely won't find someone to hold your hand and tell you exactly what you should set.
You've seen a few suggestions of what may improve and what people prefer but it's up to you to try to find out what looks best to you, since only you have your eyes.

Thanks for the suggestion. That worked for me. Guess its still a bug in fse, but we are all moving away from it in any case.

On a side note, I just realized "fullscreen" as a boolean value in profile rules does not work even though its listed as such on the post on profile rules.

Hi, i must first say that im sorry, since members here where very helpful, i'm not here to bash madVR or anything, i'm just trying, to figure out whats wrong in my case. I personally think the program i use to COMPARE the settings, is somehow overriding, and using madVR same as MPHC, since the pictures look identical to me, and few of my friends i asked, i never told them anything, i just ask them what they think about the pics.

With the help of Asmodian i managed to get madVR run much much better, but the issue is i still cannot see a difference, i zoomed 500-600% and used frame by frame method to get to exact same point of the video, no difference.

Usually you CAN very easy spot madVR difference, in videos i saw on youtube, and on tons of screenshots, the difference is huge, but im my case i see nothing even i use screenshots vs videos method, and we both know screeshots method is quite easier to spot.

What could be the cause? i have no idea really.

Have you tried other players ?
Personally, I prefer PotPlayer since it gives me no dropped frames while MPC-HC/BE does with the same madVR settings. Sometime you can't find explanations, just keep trying

MPHC works fine, i just cant find a good player with different renderer to use it in order to take screenshot from to compare it with madVR enabled MPHC.

Edit, does this looks normal?



deinterlacing and limited range?

[Asmodian]

No, your render queue is empty, it should be 7-8 / 8 or maybe 6-8 / 8. In a similar fashion the present queue should be at least 2-4 / 4. The rendering time looks OK and even if it was paused the render queue should be full (present queue would be 1-1 / 4).

Are you using DXVA2 native decoding in LAV filters? This is known to provide poor quality on Nvidia GPUs, use DXVA2 copy-back instead. Still you might not notice, the issue is only a slight blurring of the chroma planes.

Your source may be soft enough that there aren't any visible differences, even with SSIM compared to Bicubic. SSIM is good at preserving single pixel scale detail and fine texture but if you don't have any in the source you cannot preserve anything.

Don't use DXVA2 native! Especially on Nvidia GPUs, but you don't want to use native decoding at all. Use DXVA2 (copy-back) instead.

The OSD doesn't show a decoding speed issue, the decoder queue would be empty if that was the issue, and the (DXVA2) indicates hardware decoding is active.

When using native you cannot pick the hardware device to use (it has to be the same device the display is plugged into) and you are not playing anything right now, which is why the Active Decoder is inactive. Look at that same screen while playing something.

Short question:

Nvidia GTX 960 GPU
My settings
LAV Filters
Hardware Acceleration
Hardware Decoder to use --> NVIDIA CUVID <--

Should I switch to --> DXVA2 (copy-back) <--

[Asmodian]

Yes, absolutely. That or D3D11 with the GPU selected:

Is the device selection important for dxva2 copyback, or is it only for d3d11?

Thanks for your input, appreciate it!

Hardware Acceleration
Hardware Decoder to use --> D3D11 <-- (it's not in there)

DXVA2 (copy-back) (OK!)
Hardware Device to use: Nvidia Geforce GTX 960 (OK!)

Also noticed you are using LAV Video Decoder 0.70.2.80-git
Should I upgrade LAV Filters?

You can use it to use a secondary GPU with DXVA2, but its not absolutely required.

With D3D11 using "Auto" mode uses D3D11 Native mode if available, selecting a specific GPU always forces Copy-Back.
