Scan for changes in framerate / fields

[tormento]

I have an anime with intended framerates of 23.976p, 29.97p and 60i.

The video has been soft set to 29.97p to provide a "smooth" experience.

How can I deal with it? How to scan for the frames where the framerate / interlacing change starts and ends?

Here (https://krakenfiles.com/view/ZCTElUsXUN/file.html) a small sample.

TIVTC can be used to do stuff like that, http://avisynth.nl/index.php/TIVTC. Though it's more or less a pain to make it work correctly, especially if you use a non-PC player.

QTGMC to get rid of the interlacing, then dedup to get rip of the duplicates, could be used instead of TIVTC to create vfr content (unique frames + time code file).

What is the correct path to go of the two?

Can you provide me a script example? I am a real noob about fields.

DeDup: Look at the example over at http://avisynth.nl/index.php/DeDup
TIVTC: Look at example 7 over at http://avisynth.nl/index.php/TIVTC
