Here comes again: help to detect bad interlace and the deint

Well, I have bad time trying to identify and deiterlace succesfull a video.
The video originally comes from a live transmission via YT: https://youtu.be/715m771utTE

Searching and trying in the forums, I test with srestore and QTGMC with different presets. Probably is some type of original interlaced material in unknown norm, then resized and uploaded... maybe resized by YT.

If someone help me identifying and deinterlacing this Ill be pleasantly grateful.

One cut form the file downloaded (MP4, 720p, 29.97):
https://drive.google.com/uc?id=1YQhZ...xport=download


Thanks in advance, and sorry for my bad english.

Your clip is progressive, not interlaced, but badly damaged because the original interlaced footage has been resized without prior deinterlacing.
Now the field structure is crippled and the frames can't be deinterlaced any more.
You could try something like this and play with the shrink parameter:
Code:
source
shrink=380
bicubicresize(width(source),height(source)-shrink)
bilinearresize(width(source),height(source))

This is too destructive, it reduces the vertical resolution.
There is no a way to search only the motion areas and interpolate this vetically without touching all other?
