The forum won't accept my attachment. I click in the Attachments box, choose the file then click "Open", the window closes back to the message but nothing happens after that.
There's something wrong with the forum's attachments system. I'm using Chrome (Win11) and after I select the file to be attached (MPG or a ZIP), nothing happens.
Oh well, there it is, it's attached.
Had a quick look at the debug output, according to the debug output:
32bit Avisynth QTGMC was used for deinterlacing, but there the wrong field order was used:
AssumeTFF()
QTGMC(Preset="Fast", ediThreads=2)
# scaling to 768x614
Spline36Resize(768,614)
# setting output fps to 50.000fps
AssumeFPS(50,1)
(as a workaround, using Vapoursynth instead should fix that)
=> will look at it after work
