Old thread, returning issue.
When I dropped material encoded i streamclip into fcp, it opted me to change the seq settings to match the material. I said, yes, everything was good, added a few transitions, exported —- interlaced.
Grown a bit wiser since last time and for anyone wondering, this seems to be the solution:
Sequence settings —–
1920 x 1080 HDTV 1080i (last one can’t be changed to anything reasonable, why? Don’t know)
Square pixels
Field dominance: NONE (this solved it for me, it used to be set to upper by FCP, why? Don’t know)
Compressor (prores 422 in my case)
——
Exported using current settings, all is good.
