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?

I was wondering if most use artifact removal?
At what strengths does it seem to soften the image?

I would say it starts to soften noticeably around 3, I only turn it on for sources that need it.

I expect this feature to make it in before MadVR 1.0 lands but it's not a focus right now.

Good to know. Just because I'm unaware, is there any rough timetable around the release of MadVR 1.0?

You can't really do IVTC decimation if its actually 60fps progressive, and not telecined. Its a specific algorithm to remove duplicate frames from the telecining process, not a generic "make half the frames go away" kind of thing (why you would ever want that anyway?).

If its 59.94 fps which resulted from a Telecining operation from either 23.976 (ie. 3:2) or 29.97 (ie. 2:2), then it should be able to recover that as well.

"(why you would ever want that anyway?)"
I think US TV channels that broadcast in 720p60 is/was a use case.
(I'm not from the USA so I don't know if 720p HDTV is still commonly used)

it is used all over the world.

and it will not work if the source is true 60 fps.

I was rather thinking of 24p-in-60p material, I assumed that's what Anima123 was asking.
Like, what happens if a 720p60 TV station wants to show a 24p TV series or movie?

if it is was created using a 3:2(6:4) cadence and not blending madVR "IVTC" can fix this too.
