[HELP] Deinterlacing not working for me

[Selur]

You source isn't interlaced.
That file was created from an interlaced source and saved as progressive while resizing and not deinterlacing.
(this is why normal deinterlacing will not work)
If you captured this, I would recommend to re-capture it properly.
Also there are tons of ghosting since the original frame rate wasn't 59.94 fps.
If the linked file is your source your best bet would be to:
a. try to downscale to the original source resolution (yes this will destroy details)
b. deinterlace (this will destroy details and turn the combing artifacts into ghosting)
(at this point you got a progressive source without the combing artifacts)
c. try reducing the frame rate and count by dropping frames aiming for the original frame rate
d. then start denoising&co
=> if you have a source some re-encoding generations before this progressive 1920x1080 HEVC encode your chances to get a better output would be higher.
