Remove pulldown on-the-fly
I have a BDRemux ('Derailed' 2005 Director's Cut) which video is
Code:
Video: MPEG4 Video (H264) 1920x1080 29.97fps [V: Russian [rus] (h264 high L4.1, yuv420p, 1920x1080)]

Yes, madVR supports IVTC. Deinterlacing in Film mode is IVTC.

Yes the screen is good but the playback isn't. I'd upload the sample but as I wrote above after tsMuxeR all is fine. Is it a way to disable removal of pulldown in tsMuxeR?

Your frame time is still 33.37 ms, I would expect 41.71ms if IVTC was working properly. Does it work if your force deinterlacing in Film/IVTC mode? It seems to detect the cadence correctly so I would expect it to work now.

I was wrong about disabling deinterlacing in LAV Video, it isn't actually needed.
I have madVR's deinterlacing always set to (.) force film mode as video mode isn't working anyway there (as deinterlacing is broken in AMD drivers). With (.) if in doubt activate deinterlacing, the result is above. With (.) if in doubt deactivate deinterlacing:

Your display is still 60 Hz, so while madVR can remove 3:2 telecine, it practically has to add it back to display the resulting 24p video on a 60Hz screen.

nevcairiel, thank you very much! Indeed, it was because of my 60 Hz monitor. On my projector (24 Hz), the playback is fine.
I still don't understand why I can't get smooth playback on 60 Hz without removing pulldown (60 Hz is the "native" refresh rate for 29.97fps video, isn't it?) and why other NTSC and 24p movies can be played just fine on my 60 Hz monitor (they should stutter as this video does with pulldown removed, shouldn't they?). Is it a madVR bug that it doesn't detect the need of deinterlacing here? I started MPC-HC on the projector screen (using "/monitor 2" parameter), but without forced deinterlacing, madVR still doesn't enable it. Is there any disadvantage to have deinterlacing always forced (Film mode) in madVR? BTW tsMuxeR removes pulldown here in an improper way - the result file is sped up: http://mir.cr/FWJCCGKP

if you deinterlance a 3:2 telecine file you will end up with a 59p file that has a 3:2 judder in it so it can never be smooth with a simple deinterlancer. Quote:
if not the file is incorrect or you changed some settings in lavfilter. and if all these things are correct than it maybe a bug in lavfilter or madVR. but this is not the first interlanced BD run with madVR and lavfilter. Quote:

for best quality leave film mode active on madVR and use YADIF in lavfilter if the file is interlanced. GPU deinterlancer are prettym bad with these drivers these days. Quote:
