The bug fix to ffmpeg I mentioned earlier, the one that fixes packing raw video
into a .mov container, has an implication which breaks the recent fix to raw
video handling in mlt. Enclosed is a patch that makes mlt work with both the
original ffmpeg as well as the patched one.
I don't know why both methods of setting the video interlacing in a stream are
necessary, but that's a question for dedicated ffmpeg hackers.
Given my research into what works and what doesn't, you may want to consider
changing the container type on kdenlive's HuffYUV export from avi to mov, so
that interlacing is preserved.
