In Hybrid is says 'Pixel aspect ratio' in your screenshot it says 'Display aspect ratio'.
=> [INFO] About pixel aspect ratios,..

Obviously: If you have a real 29.97fps source (with 29.97 unique non-blended frames) and you remove frames, you will lose motion smoothness and there is nothing you can do about it.

I take a look in some file, strange is 4 good frames and 1 duplicate, another 4 frames and a duplicate, and so on..so is not telecined..what I need to do? How I delete the duplicate?
RE: What noise is that? - Selur - 08.07.2025
No, that's telecine.
If it's a fixed pattern you can use QTGMC and then SelectEvery
RE: What noise is that? - Doom83 - 08.07.2025
But this give without bob, original 29.97
If make TIVTC give some stripes
Actually dont know how to set selectevery, try Tdecimate
RE: What noise is that? - Selur - 08.07.2025
Like always, I need a small sample (with horizontal motion) to give a script suggestion.

Ok that a shot clip from interview, rip and untouched..4 frame and a duplicate..maybe tdecimated at 23.96 seem the good option...
RE: What noise is that? - Selur - 09.07.2025
Yes, TIVTC seems to be the right approach, so overwriting the scan type to 'telecine' should be enough.
Alternatively, you could replace the duplicates with interpolations.
