Topic: Deinterlace Stutter
Hello all. I'm hopeful you can help me get to the bottom of a deinterlacing oddity I'm experiencing.
What's happening is that I have some interlaced content I've captured (VHS source), and I'm trying to do a QTGMC/Bob deinterlacing using Hybrid. Things have mainly gone well, except I'm experiencing an odd jitter on content that has been deinterlaced. On closer examination, it appears that what's occurring is that the fields are occasionally being deinterlaced in the wrong order.
For example, if the proper frame order is...
It seems to be playing back something like...
I say something like that because I'm still not 100% sure what it's doing. At first I thought it might be something with my source content. However, when I use software like VLC to handle the Bob Deinterlacing on the fly, during a simple playback, it does so without issue. This weird stutter only seems to be happening with Hybrid handling the deinterlacing.
I'm running Hybrid version 2017.3.26.1. I have some example content here I can show you.
Here is the source media...
Here is the MediaInfo on the source file...

Because this forum apparently doesn't let you post more than one link in a single post (odd), I guess I'll include a link to the resulting media in a separate post.
Thanks for your help.
