Deinterlacing Quality nvidia/amd/intel

[huhn]

This is a simple gpu deinterlacing comparison, to good an idea how got the gpu deinterlacing is.

All screens are done with MadVR and mpc hc. no dither and spline3 ar everything.

All video gpu settings are disable except Deinterlacing.

amd uses Automatic with Pulldown Detection driver 14.3 beta
nvidia uses Inverse telecine driver version 335.23
intel use nothing i haven't found anything in newer driver but the picture is too dark for some reasons driver version 10.18.10.3464

anime source 1440x1080 3:2 cadence ar 16/9 tv cap mpeg2 ~12 Mbps

nvidia looks pretty good in this test intel doesn't looking to bad too but...
i found this deint error (http://abload.de/img/intelwaveerror0os8j.png) and it is too dark for what ever reason.
amd looks kinda bad blocking and little wave errors maybe automatic deinterlacing isn't good for anime or in general?

all frames are taken after 10 or more "played" frames. else things like this can happen:pic1 (http://abload.de/img/errorintelp1s6s9x.png) pic2 (http://abload.de/img/errorintelp2qbsgx.png) look at the "BLUE SKY" text this looks terrible like nearest neighbor bob this doesn't happen if multiply frames are shown before.

i like to add a non anime screen and if possible a true 30i -> 60 fps source too. but i'm pretty bad in judging normal films so a sample or just the screen from an intel/nvidia/amd gpu would be really nice.

i may add CUVID and YADIF too but CUVID and nvidia deint uses the same deint logic so not sure if this helps at all.

Links are dead :(

works fine for me but it's 4 years old so it's not represent of the current situation.

Now the links really are dead. :) Abload apparently shut down at the end of June.

Thread is still relevant though.. not sure yet if it's an OS issue or the actual GPUs.. I think it might be the GPUs, but I have observed that while Intel continues to be able to deinterlace video, AMD RDNA2 doesn't do it properly on Linux. It does sort-of do it in the sense that it removes the combing, but the scaling is really distorted. Low-resolution and looks like bars stacked on top of each other compared to Intel on Windows which is a clear image scaled cleanly. I've been seeing some comments here and there that there might be problems with AMD deinterlacing across the board now but it is not clear to me if it is all recent GPUs and drivers or not.

Possible that AMD might be a hard avoid if deinterlacing is needed.
