Periodically freeze frames

[kingcrimsonster]

When I use Avisynth QTGMC deinterlacer I observe this defect.
When I use Vapoursynth QTGMC deinterlacer with similar settings - no defect.

No clue what Vapoursynth script you used, my guess is that this isn't a bug in QTGMC, but a problem with the source filter.

but a problem with the source filter.

Can this be fixed?

Since the used source filter used in Vapoursynth isn't available for Avisynth, your only bet is to try the other filters available, like
a. lwlibavvideosource
b. FFMS2000
b. FRIM
c. DGDecNV (<- requires a license which isn't free and an NVIDIA card)

I try lwlibavvideosource - no this defect

Happy that worked out.
If you find a way to identify files which have this problem through mediainfo&co I would happily add a workaround for it.
But without a way to identify such files, there isn't anything I can do.
