Jinc is the the highest quality non-doubling scaler. It is a simple very high quality choice if you do not notice the difference from NGU.

The video block in the 1050 decodes pretty much everything and hardly consumes any power, and it's dedicated so you're not using other processing resources. The only case I'd see in your situation for not using it would be if copy-back mode has problems (usually with UHD content).

I'm not using any processing/enhancement/refinement, and yet on my system the picture looks more similar to your madVR screenshot than to your VLC one (albeit with more banding artefacts).
I noticed that madVR produces a 1920x800 image and your VLC screenshot is 1920x804, the aspect ratio is different. I don't know much about VLC, but what renderer and decoder does it use? If it's DXVA and/or EVR, are you sure your graphics card video 'enhancements' are not processing the image? And how does it produce screenshots? Or did you use print screen?
I also tried basic EVR, and the resulting image is 1920x804 like your VLC screenshot, but with the same brightness levels as madVR. I think the VLC image is the bad one here.

Edit: this scene is a very good showcase of how much better at rendering madVR is than GPU drivers & EVR, btw!

I watch only 1080p content So copy-back is the right choice?

Can someone give me tips for faster skipping/jumping inside low quality formats like porn? It needs 2-4sec to rebuild after jumping with my high settings on NGU AA, but maybe I did something wrong. HD 1080p movies work without delay.

I have tried to lower the setting and deactivate the NGU, but it doesn't really help, so it seams something else is wrong.

I'm testing them but I do not see any difference between the various scalers, maybe I can not figure out what the differences are and with what images i have to do the tests?

GPU deinterlacing is definitely working, no combing whatsoever as in your screenshot.
I left madVR at its default settings.

I may be wrong, but could madVR + GPU deinterlacing be too much for your graphics card? Have you tried with EVR just to see if deinterlacing works without madVR? Have you tried lowering madVR processing quality?

EDIT: I see your average processing time is ~23 ms. 50i video deinterlaces to 50 fps, not 25, so it means 20 ms per frame. I think it's likely your GPU has no processing resources left to deinterlace in addition to madVR processing. I know Radeons at some point had a 'feature' that disabled some video processing options if the GPU was maxxed out, I don't know much about NVIDIA GPUs yet but could it be that's what happening?
I just realize that when you were testing this I didn't know yet that it only breaks when I change channels.
Could you try it that way? (If you're still around)

Maybe you should edit out the boring stuff before playing the video.

Haha

When I skip/jump the decoder queue goes up over the set limit from 16 to 19/21 for a few sec, in this time the video stops.

I'm using a i7 7700k, should I set the decoder queue higher then the default to fix the problem?

Been noticing a few instances recently with seeking where the picture freezes but audio continues. Seeking sometimes fixes it. Was using NGU Sharp and d3d11. Haven't done any testing. Anyone else had this recently?
Only appear to have this happening when I pause.

Audio continues and picture freezes yes, but I only have the problem on low quality videos. I test it with NGU AA, Sharp, xbr, and CIVID, D3D11 but there was no different.

I only found that decoder queue overflow at seeking.

Hi!

Can anyone tell me how do I use the madVR internal decoders? They don't appear as a system codec so I can't set them in media software to be used. So how?

The DXVA decoders are surely there because apparently they somehow got enabled in strange circumstances:


Even deinterlacing started working. So how do I the built in decoder normally?

madVRs built-in decoders have been removed a long time ago, in v0.87.15 to be precise. If the OSD says DXVA, that means the decoder is delivering frames in DXVA2-Native mode, but not that madVR is doing the decoding.

Official comparison by madshi available here:
http://www.madvr.com/

Unless you have a very bad eye sight (or something terribly wrong with your display), the difference in sharpness should be very apparent when watching a movie. You can also make a screenshot of the same frame using different scalers, for comparison, but if you do not see the difference during playback it's a waste of time.

Quick question.
So what's the better/right option here for HDR movies?

madVR: 0-255 nvidia: 0-255 TV: 0-255
madVR: 0-255 nvidia:16-235 TV: 16-235

in some movies with everything set to full-rgb the blacks look washed out.

Well, I saw that, but it only says "removed software decoders" and not DXVA decoders. So that's confusing.

Also, I tried removing the files and it works the same way. Which is even weirder. Maybe LAV wasn't working at all this way?

The icon certainly didn't appear and the settings certainly don't reflect using DXVA. (I don't see LAVVideo.ax in the threads either.)

Where are the settings for LAV Video normally stored?

There never was anything but the software decoders in the first place.

@mzso I reinstalled ProgDVB and tested again. With the default config you're indeed right that deinterlacing gets turned off after the first channel change and there is no way to get it enabled again without fully stopping and opening a channel again.
Fortunately I was able to fix it by changing this setting in the options: Main => Speed of channel changing = Fast
Note that this value probably requires that the same decoder filters be used for all formats because they are kept active upon channel change. It's not really a problem because you can use LAV for all formats.
Afterwards, deinterlacing stays on even after a channel change.

Please confirm it works on your side too so I can uninstall ProgDVB, I can't stand this software.

Those are both correct, the first is preferred but they should look basically the same if the TV handles both limited and full range correctly.

HDR or not changes nothing. How are you displaying HDR? If you are using pixel shader math to convert to SDR try turning up "this display's peak nits:"

Is D3D11 faster then CUVID or the same at the end? What's the benefit?
