QTGMC in Hybird Only Rendering Over a Minute of an 11 Minute File

[vcr4200]

Hello everyone, I've been capturing some VHS tapes I have with AmaRec TV, (VirtualDub had too many audio sync issues), the capturing when without a hitch. The main problem I'm having is with the QTGMC deinterlacing in Hybrid, after many failed attempts I finally managed to deinterlace an eleven minute AVI file... until I realised it only rendered about a minute's worth of footage.

I don't understand how this happened, if it was due to my laptop's age, (which I've had for nearly five years; HP 14s-dq1xxx); anybody know what the problem might be?

Wild guess is that the used source filters has a problem with your source.
So try switching source filter. If your source is an .avi file and you got 64bit vfw decoders for that content on your system try using AviSource.
Other than that there are tons of stuff that could go wrong.
Unless you are sure how it works, remember to check the Vapoursynth Preview.
