DeInterlace QTGMC-Bob strange frame issue

[Selur]

But still puzzled as to why that happens...

The frame jumps seems to be related to QTGMC when using for example:

# Deinterlacing
clip = core.yadifmod.Yadifmod(clip=clip, edeint=core.nnedi3cl.NNEDI3CL(clip=clip,field=2), order=1, mode=1)

(YadifMod, Mode=1, Order=1, Edint = NNEDI3CL, NNEDI mode 2)
the result looks 'okay', but with lots of ghosting in some scenes maybe additionally using sRestore might help,...
All in all I guess that the source was original telecined and then captured to interlaced or something similar,...
