Bad interlaced

[JAX75]

Hello how can I deinterlace this video encoded in progressive 30fps originally 25fps

[jagabo]

Decimate first, then deinterlace.

LWLibavVideoSource("pv.mkv") 
AssumeTFF()
TDecimate(Cycle=6, CycleR=1)
QTGMC()

[JAX75]

thanks for helps here is the result I don't think we can improve it further

This is what you get if you apply QTGMC and then BasicVSR++,.... but applying BasicVSR++ doesn't really make sense on such resolutions unless you got a decent NVIDA graphics card. On my old Geforce GTX 1070ti, I get 0.1-0.2 fps, and the result seems a bit too smooth.

Not sure whether it's of any help, this is the Vapoursynth script I used:

Another approach would be to apply MCTemporalDenoise(settings="very high) + mClean after QTGMC.

[JAX75]

possible to have the same thing via avisynth ?

[Selur]

Yes, all the scripts I used for MCTemporalDenoise+mClean.mp4 are available for Avisynth:
MCTemporalDenoise: http://avisynth.nl/index.php/MCTemporalDenoise
mClean: https://forum.doom9.org/showthread.php?t=174804
QTGMC: http://avisynth.nl/index.php/QTGMC
so I see no reason why this can't be done with Avisynth.

[JAX75]

yes possible via staxrip except that I need the parameters for QTGMC

[Selur]

I used:

clip = havsfunc.QTGMC(Input=clip, Preset="Fast", TFF=True, opencl=True) # new fps: 30
# make sure content is preceived as frame based
clip = core.std.SetFieldBased(clip, 0)
clip = clip[::2]

->

AssumeTFF()
QTGMC(Preset="Fast", ediThreads=2)
SelectEven()

you could also try the calls jagabo mentioned first and then just add MCTemporalDenoise and mClean.

ok i will test
