I hope this isn't a stupid question...

Why does _DurationDen after QTGMC still show 25fps (and not 50)? VirtualDub sees 50fps, ffmpeg too. But propshow still shows 25.

Wiki
_DurationNum

int _DurationNum

_DurationDen

int _DurationDen
The frame’s duration in seconds as a rational number. Filters that modify the framerate should also change these values.
This fraction should always be normalized.

Perhaps show both _DurationNum and _DurationDen for each instance.

maybe it's better to report that in https://github.com/Dogway/Avisynth-Scripts/issues
