Shot DVC PRO HD 1080i/24p editing @ 23.98 (Whoops?)
Hey all, so I just realized I’ve been editing DVC PRO HD 1080i/24p footage from an HPX170 on a 23.98 time line. It appears normal. Shouldn’t it be on a 29.97 timeline since it wasn’t shot 24PA?
So I made a new sequence and converted it to 29.97, and everything looks hunky dory. I notice no difference. Shouldn’t there be a visible difference? Otherwise, what’s the difference between 23.98 and 29.97? I suppose it’s not an urgent problem, but I’m just curious.
Furthermore, when I “get info” in my finder, the clips say 1080i60. Does this have anything to do with it? That’s just the fields, right?
Thanks so much.

If you shoot 24P, typically you get a 29.97 (59.94) file with pulldown added (24 over 60). If it’s 24PA, when you capture or transfer, and remove the advanced pulldown, you get 23.98 (23.976). The reason 23.98 looks the same as the 29.97 is FCP adds pulldown to the 23.98 timeline as it plays.
If FCP set your sequence settings when you dragged in the first clip and it shows a timebase of 23.98 then the clip must have been shot 24PA.
