[Robert Houllahan] "I think EDL export from Final Cut is much less robust than from Avid..."

This isn't a problem with the EDL, though, as far as I can tell. The EDL in these instances is accurate. This is, as far as I can tell, a Resolve bug. The algorithm it uses for checking whether a given timecode range is contained within another timecode range doesn't seem to understand clips that cross the midnight barrier. So if it's looking for media from reel A001 starting at 00:00:01:00 and going through 00:00:10:00, it doesn't understand that it if there's a reel A001 clip that runs from 23:59:58:00 to 00:01:10:00 it should look for it there.

It's easy to see why. In all other cases, if you're looking for a clip that encompasses a given timecode range, that clip's start timecode will be less than the start timecode of the range, and its end timecode will be greater. In this case, the former isn't true, and the code wasn't written with that edge case in mind.

(Vaguely-related rant: I don't understand why the industry hasn't added day, month, year, and camera identifiers to TC/reel information by now, to give every frame ever captured by every camera a globally unique code. That would solve a lot of annoying post problems.)
