Since you don't give the only relative and useful information, being
which preset your screenshot is based upon, I have no clue what it is you you're doing or why you're getting what you're getting. Because
of course both Final Cut Pro
and Compressor can output i.e. interpret interlaced files! 🙄 Always have and always will. So I don't know where you're getting your weird skewed information from, nor does it have anything remotely to do with the new media extensions or anything else. 🤨
It's called "user error".
Maybe just start
with the correct preset in which case you can set any field dominance you want?
… as a random example.
And merely
HEVC does not support interlacing.
And if the file is not flagged correctly, then neither app can recognize the correct field dominance. Which we don't even know if that's the case, since, again, all relevant information is missing. But if they aren't, you simply set it
manually? Again something that you
obviously can do in Final Cut as well, in the clip's
settings if needed.
After which you obviously have to use a
project set to interlaced as well.
Seems like Mpeg2 is the only way to get interlaced out...
Nonsense.
