is/was a planned feature that is not yet released.
his dev build clearly can do it as you can see.

I see, so this was over a dev build... I hope it is still due for release then. It would be an incredibly helpful feature, given how useful vapoursynth is.

MPC-HC and Vapoursynth Integration?

It's integrated in PotPlayer

Is it really? Interesting. Does Potplayer support directshow filters like LAV filters, madVR, xysubfilter, etc.?

Yes and yes.
There are some packs/bundles/installers with madVR/AviSynth+/Vapoursynth presets available too.

Wow! Thanks for the tip, do you have any links?

I was watching some comedy HDTV broadcast when I noticed moiré on the background, so for reference if that is of interest to some people, here is what can happen when you (let the renderer/display try to) deinterlace 25PsF material instead of weaving the fields as should be done.
Sadly, neither my NVIDIA or madVR can detect and ivtc a 2:2 cadence in 50i.

https://drive.google.com/open?id=1GR...zg8mxrh-oF2BFI

Note that this is HD so moiré/aliasing is the 'only' artifact you'll see, but if it was SD you'd have NVIDIA suboptimal deinterlacing artifacts in addition to it, which is even worse. (I got the case on the recent broadcast of Stewart Lee's show on BBC, which I can receive only in SD)

PS: before anyone accuses NVIDIA's deinterlacing to be the cause of this, know that I also tested YADIF and it acts exactly the same.

did you try film mode in madVR?

Yes of course that's what I use to fix this (using a keyboard shortcut), but what I meant is that's not really user-friendly, to have to manually try film mode with each different material you watch.
Is 2:2 cadence really that difficult to detect algorithmically? I don't get why all ivtc'ers can detect 3:2 just fine but not 2:2.

what are you talking about?

the ivtc in madVr detects it fine so madVr support 2:2 cadance.
there is no automatic detection and hardware deinterlancer can't do it anyway.

where does it detect 2:3 but not 2:2?

I think I'm confused so I'll rephrase my question: is there any way with madVR - using DXVA if needed - to dynamically detect and recover the original 25p encoded in 50i?

You say "there is no automatic detection and hardware deinterlancer can't do it anyway" but this NVIDIA page says even GPUs from 10 years ago could do it: http://www.nvidia.com/object/geforce_8400_features.html

Inverse Telecine (3:2 & 2:2 Pulldown Correction):
Recovers original film images from films-converted-to-video, providing more accurate movie playback and superior picture quality.

Bad Edit Correction:
When videos are edited after they have been converted from 24 to 25 or 30 frames, the edits can disrupt the normal 3:2 or 2:2 pulldown cadence. PureVideo uses advanced processing techniques to detect poor edits, recover the original content, and display perfect picture detail frame after frame for smooth, natural looking video.

when you give it 30 frames 60 fields it will output 60 frames which and without IVTC which was optional in the past not sure if it des anything anymore. while it looks like nvidia can field match it can't decimate so the quality is better but the judder is still there.

Okay but I'm only interested in PAL, not NTSC, so I would be happy with just automatic 2:2 detection that gives back 25p. (Edit: or would it give back 50p with successive identical frames? I need to test this further...)
Originally I thought it was due to the way madVR called the DXVA deinterlacer that automatic 2:2 pulldown detection wasn't working but now I've tested with default EVR and DXVA2 Native and NVIDIA can't detect it either, so I guess it's the GPU's fault again.
Thanks for the explanation.

i know for sure that field matching worked in the past but yes the output would be 50p with a 2:2 frame cadence.

something broke with win 10. and never forget when testing the nvidia hardware deinterlancer needs about 5 frames before it works properly.

The GPU should be capable of detecting that, but it won't actually decimate down to 25p, it'll just not apply video-mode deinterlacing, which might result in lowered quality otherwise.

Is there a way to force decimation of progressive 59.94 fps video? When I apply film mode on this kind of videos, madVR always detect it as cadence 2:2, and no decimation on it.

Just wanted to confirm a fix for FSE on windows 10 1803, I was having delays of like 2-4 seconds before playback started when going to FSE, but it was just focus assist! I had it off but forgot it was set to turn on for "fullscreen games"

after disabling that windowed and FSE are both working fully for me on windows 10 1803 and nvidia driver 398.36
(I also set "disable fullscreen optimizations" on the exe for my player, jriver mc24, to force regular FSE but it seems to work about the same either way)

Turns out PotPlayer only supports 8 bit processing in the video filters, and the devs have no plans to implement 10 bit... I guess my best bet is hoping that the dev build mentioned here gets released. Does anyone know if this vapoursynth feature is still in the works?
