Nvidia 250, 650 and intel SBC (3000?).
I had deinterlacing set to auto in potplayer which led to undesired results. After disabling it evr and madvr 59i is comparable to WMC. WMP is still an issue and looks terrible. I don't know how I had missed this, potplayer had been problematic for me in the past. Recently had some issues with potplayer that a reset fix. Now I can watch these videos that madvr ivtc doesn't handle well with madvr without encoding.

It was set to bob which would indicate full frame rate and played 59i that are really 59 fps fine. It caused noticeable frame jumps regularly and on occasion the video would slow mo. The same things happen in WMP currently for me.

The sort of effect I'm seeing in WMP can be reproduce by encoding the file to 59.97 fps and playing it. Why is dxva deinterlacing nice and smooth while after encoding the dupe frames are noticeable and there's slow parts?

you can not simply encode 29i to 59p you need a deinterlacer for this. so it all falls with the deinterlacer you choice it is possible to use the "dxva deinterlacer by using directshowsource with cuvid. but I can't recommend directshowsource at all.
so what deinteralcer did you use to encode the file and what type of file was the source telecine 3:2, 2:2, true interlaced or something else? |

Yadif, nnedi3 and bob all output bad movement with dgnv feeding a 3:2 29i source, same as with source I posted earlier. dgnv bob deinterlacing shows bad movement. DSS using lavfilters hardware and yadif deinterlacing also show bad movement.
I'm out of ideas. It would seem reproducing dxva deinterlacing would be simple while encoding but it seems elusive if not impossible.

Yes 59p output, it's smooth with dxva deinterlacing expect it to be with deinterlacing filters as well?
Some tv shows are time compressed and are intentionally missing frames which looks fine when watching on tv or with dxva deinterlacing at 59p but not when encoding to any framerate.
