The sample provided certainly looks like interlace-> progressive issues
However istr that when piping input to ffmpeg interlace flagging gets lost.

It is also worth remembering that any auto inserted filters will operate
progressively, so need to be replaced with explicitly declared instances
that set interlace handling.

I wonder why a more conventional command line is not used?
