[BUG] Various bugs with latest dev build (2020.09.25-21270)

[Selur]

C:\Program Files\Hybrid\64bit\vsfilters\Support\libfftw3f-3.dll is missing.

you are correct, copying the one from "Hybrid\64bit\Avisynth\avisynthPlugins" is okay.

The AviSynth64 previewer crashes.

Sadly, no clue what's causing the crash, works fine here and we use the save file versions. :/
Looks like initializing the AviSynth.dll fails.
Does this happen with all files for you?

my request to add Match preset / Match preset 2 / Match enhance for QTGMC

probably not happening atm.

For QTGMC progressive options, if Input Type = 1, 2, or 3, then QTGMC will always be inserted into the script, even if the "Auto" check box is cleared. The only way to remove QTGMC from the script is to enable the "Auto" check box, then change the Input Type back to 0. Expected behavior is on progressive input video, QTGMC will be removed from scipts if "Auto" check box is cleared (even if Input Type is set to 1, 2, or 3 for progressive options).

If you set QTGMC to input type != 0 you tell Hybrid to treat it like any other filter, thus Hybrid will add it.
if you disable 'Auto', deinterlaced switched to 'Yadif - fast'.
-> only way to make this more user friendly would be to:
a. remove 'Input Type' != 0 from the (De-)Interlacer support
b. add QTGMC to the denoise filters where it will only allow input type != 0
-> this will take a while to implement since QTGMC has tons of options
