Camera files are 30fps. I need to deliver 29.97 for broadcast.
A) Set project properties to 30 or 29.97?
B) Found script that shortens (at the event level) to 29.97 and disables resample. Use it and render out 29.97.?
C) Just pretend it is 29.97 and render out as such, without script?
D) Render the whole thing at 30fps then bring it back and render as 29.97? How?

What camera is this? Chances are the footage is 29.97.

But yes, even at 30.00, you can edit and export as 29.97.

But it's very likely it's not 30.00.
