[MAJOR BUG] Encoding finishes prematurely

[Selur]

Also check your energy saving settings.
Since the Vapoursynth Preview shows all the frames, something must be messing with the encoding call:

As a side note, I would also advise putting the temp folder (not in the AppData folder) to a separate dedicated folder and exclude it from the virus scan.
