In Hybrid is says 'Pixel aspect ratio' in your screenshot it says 'Display aspect ratio'.

You look for pattern if you bob the content, read: [INFO] Interlacing patterns

You could add interpolated frames: "Filtering->Vapoursynth->Frame->Interpolation->Frame Interpolation" (on Mac, there are way less available methods for this, than on Windows, especially with a modern gpu and vs-mlrt or torch add-on).

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?

No, that's telecine.
If it's a fixed pattern you can use QTGMC and then SelectEvery

But this give without bob, original 29.97
If make TIVTC give some stripes  
Actually dont know how to set selectevery, try Tdecimate 

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...

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.
