Great! I’m feeling better about this. Here is an expanded view of the file names:

I was using waveform and vector scopes during grading and so the black and white levels should be good. I was careful about saturation etc. as well.
Unfortunately, my original footage was not shot in 24p (it’s 1080i), so I don’t know how that conversion—done by Premiere—affects how it plays.
So, if all this looks good, I still need to re-format the drive, for the theater to use it, correct? Hopefully I can do that from my Mac disk utility. Thanks so much!
