Out of bounds frame requested

Does the issue also happen for you if you use the 'Avisynth Preview' and not the 'Avisynth Filter Preview' ?

If the problem is only the "Avisynth Filter View" it is probably because it applies QTGMC two times:
1st on the Source
2nd on the FilteredSource

SourceFiltered = Source
Source = Source.AssumeTFF()
Source = Source.QTGMC(Preset="Fast", ediThreads=2, PrevGlobals="Reuse")# added PrevGlobals="Reuse" to handle multiple QTGMC instances
Source = Source.SelectEven()
SourceFiltered = SourceFiltered.AssumeTFF()
SourceFiltered = SourceFiltered.QTGMC(Preset="Fast", ediThreads=2, PrevGlobals="Reuse")# added PrevGlobals="Reuse" to handle multiple QTGMC instances
SourceFiltered = SourceFiltered.SelectEven()

in old versions Hybrid used:

Source = Source.AssumeTFF()
Source = Source.QTGMC(Preset="Fast", ediThreads=2)
SourceFiltered = Source

instead of the above which speeds up things a log, but caused crashes whenever a filter was applied before the deinterlacing which easily happens if the user changes the filter order.
So in order to avoid that problem Hybrid switched to appying the deinterlacer separately on the source and the filtered source.

Ps.: I still don't get the "FFVideoSource: Out of bounds frame requested" here.
