[AnimeIVTC] Inability to Inverse Telecine

[DEFiANT]

Premise:
I recently downloaded a MPEG-2 TS capture of Doraemon (1979) that had been telecined (from 24fps), and in 1080i. I want to IVTC to stop the jitter frames.
However, the script asks me: 'What is your input clip?? It's not 30fps NTSC nor 25fps PAL", despite it being 29.97 FPS.

Removing the code responsible for raising an exception then claims an 'access violation'.

I have attached a sample of the video here.


Please help resolve this or advise of any alternatives.

Thanks

Using this filter in avisynth will usually help hide or fix those artifacts in the video.
santiag(strv=0, nns=4, nsize=5)

my 2 cents after a quick glance:
Isn't this soft telecine and should be DGSource&fieldop=1 or MPEG2Source&fieldop=1 ? (I wouldn't use AnimeIVTC on this)
For the small scratches/dirt DeSpot/KillerSpot/SpotLess/RemoveDirt/... seem to work fine.
For general statilization I would try StablizeIT or similar.

What source filter are you using? LSMASH's LWlibavVIdeoSource() has no problem opening it and gets 30000/1001 as the frame rate.

I think your problem comes about because the video is variable frame rate. It alternates between 33.33 ms and 50.00 ms per frame. Resulting in an average of 24 fps, 3:2 pulldown.

Hello, sorry for replying so late. I used FFMPEGSource as I thought it could be a one-size-fits-all. I have changed it to the correct plugin, thank you for your help. The framerate is fixed.

Sorry for the late reply. I confirmed the video is 29.97fps and uses 2:3 pulldown. I ended up using TFM() and TDecimate() for IVTC and LWlibavVIdeoSource() for the video. Does this damage the video in any way?

I will be sure to try the noise removal and AA you've suggested once I've done a Delogo.
Additionally, thank you for making Hybrid, a tool that I have used on Mac for many years because of lacking Avisynth support.

Thank you for the input. I will Delogo the video first and attempt to fix the artifacts.

Had to test some stuff in my setup and played around with the sample (script) using Vapoursynth and machine learning - doesn't work on Mac, so probably not that helpful.
