how to process the pulldown portion of videos from DVDs in vapoursynth

[tda]

I'm wondering if I can get some advice. I'm processing a bunch of snowboard videos from DVDs. These videos often seem to have messed-up formatting, and are often a mix of progressive, pulldown, and interlaced. The pulldown portions usually have a "combed-combed-clean-clean-clean" pattern.

To process the pulldown portions of these videos, I've tried a bunch of different vapoursynth functions like deblend, but I can't get any of them give good results. But I feel like there must be a vapoursynth function for processing this type of video since that combed-combed-clean-clean-clean pattern appears in so many of these videos.

I have put a link to one video below. The combed-combed-clean-clean-clean pattern appears often after the live action begins around time 02:10. If anyone knows how to process this type of video in vapoursynth, please let me know.

The whole intro is a mess, there are progressive images added onto interlaced content, progressive content, interlaced content,....
But even then you got parts where the fields already contain blending.
Stuff like wobbly might help a bit:
https://github.com/dubhater/Wobbly + https://github.com/Jaded-Encoding-Thauma...bbly-guide and probably would end you with vfr output.
But to do it properly, you would have to basically undo all the authoring of the source, split it by scene, handle each scene separately and then decide what to do to combine the content back together. On some scene you can get away with bobbing and replace duplicate, but due to the quality of the source threshold would also need to be adjusted per scene.
=> This is not something Hybrid is really suited for.
