IVTC is not working correctly for non linear source

There are sources (many) that were created by joining differentry pulluped 24000/1001 > 30000/1001
For example if you get pulldown scheme for first scene. On second it may fail, because other fields should be dropped.
Now Video AI can’t handle them.
Yes there are no terrible frames like from very different fields in output. But still you can see artifacts of incorrect fields.

Uploaded it. 04.mkv
Also I’v just uploaded Book 1… mkv file. Its quite strange interlaced source. Looks like IVTC is needed and then all bottom (or top) fields should be skipped because of some sort of bad scan or something like this (all models fail to deinterlace it normally).
