Thanks for the help Carl.
Seeing the difference isn’t that important, really what I’m trying to accomplish is outputting 1080i video using the FFMPEG wrapper for the DeckLink SDK. I’ve tried numerous combinations of filter settings with either 1080i or 1080p source content, but I think there I just a limitation/bug in the DeckLink wrapper/device code that’s preventing me from outputting interlaced video. Any clues on how to fix this would be amazing!

How do you expect to see the difference between interlaced and
I believe the tinterlace filter works fine but without horizontal
movement you will not be
able to see a difference.
Note that the following should simplify your command line:
$ ffmpeg -f lavfi -i filter1,filter2, ..., filtern
