the filter gives a mathematically perfect solution to such(fades were done AFTER telecine which made a picture perfect IVTC pretty much impossible) problem, and it's now time to kiss "vinverse" goodbye cuz "vinverse" is old and low quality.
unlike vinverse which works as a dumb blurring + contra-sharpening combo and very harmful to artifacts-free frames, this filter works by matching the brightness of top and bottom fields with statistical methods, and also harmless to healthy frames.

Code:

core.ftf.FixFades(clip, mode=0, threshold=0.002, color=[0.0, 0.0, 0.0], opt=True)

clip: clip to be processed

mode: could be 0(default), 1, or 2
0: adjust the brightness of both fields to match the average brightness of 2 fields.
1: darken the brighter field to match the brightness of the darker field
2: brighten the darker field to match the brightness of the brighter field

threshold: threshold for the average difference per pixel, on a scale of 0.0 - 1.0, but could go beyond 1.0, the frame will remain untouched if the average difference between 2 fields goes below this value

color: base color of the fade, default is [0.0, 0.0, 0.0](black)

opt: call the fastest possible functions if opt=True, else call the C++ functions.

INPUT CLIP MUST BE 32BITS FLOATING POINT FORMAT!!!
apply this filter AFTER field matching!!!
