>>235046Not OP, so don't take it out on him, but you've not done the IVTC right.
You're getting blended frames from combining the fields incorrectly; blended frames interfere with the way modern video compression works by storing the differences between it and its neighbours, and take up a load of bits that could be improving the quality of the whole video.
If you've still got the raw capture, have a play about with IVTC settings until you get clean progressive video. If there's live-action adverts or trailers, you might have to use different IVTC settings for them and for the movie.
