Comment (by emcodem):

 Sure you can also see in ffmpeg that the interlacing is not set. Sorry, I
 should have already learned that from reading tickets over the last years.
 Thought that using ffprobe makes it more obvious. Below we see that there
 is no interlacing defined in Stream #0:0. I hope using the latest nightly
 build from zeranoe is fine!
