[GUIDE] VapourSynth + QTGMC Deinterlace + Hybrid UI FAQ for macOS

[shijan]

I just downloaded MKVToolNix-50 form Videohelp again https://www.videohelp.com/software/MKVToolNix and it appears that it can't start even without Hybrid. Seems just a broken release.

UPDATE: Seems it is some damaged MKVToolNix-50.0.0.0 version at Videohelp.
MKVToolNix-50.0.0.1 downloaded from https://www.fosshub.com/MKVToolNix.html works well.
