I scoured the whole forum and found a lot of questions pertaining to this topic but nothing that addresses precisely the question i am about to put forth:
Ok, all my footage is shot on Canon 5d, i transcoded everything to prores 422 and when i command-I the clips in quicktime or check in "item properties" it shows them all as 23.98. When i dropped the clips into a fresh timeline, the sequence settings conformed to the footage with 23.98 as the fps. However, when i viewed advanced settings it shows the sequence fps as 23.976. Now i am confused, because this seems like a very small difference between 23.976 and 23.98 but seems that a lot of folks on the forum here say even the slightest difference in frame rates is gonna make the edit difficult. So, how do i really know if my footage is 23.98 or 23.976 and the computer and FCP are just rounding up? I need to know.
Also, I have non-canon 5d footage i need to transcode to prores to match this footage that's going to be included in this timeline and i need to know whether to transcode it to 23.976 or 23.98. Please let me know. this additional footage by the way are mp4's with various frame sizes (the project sequence settings are already set right for the main footage which is 1980x1080 canon 5d stock).
So then it's ok for 23.976 and 23.98 clips to be used interchangeably and mixed together on the same timeline? I thought 24 fps was pretty much the same as 23.98 but i know people on this forum have said that mixing 24 and 23.98 could cause problems! so you can see why i'm confused here.
I have a knack for spending 50+ hours on an edit only to find that i have to rebuild it all from scratch because of some little mismatch or other.
On that note, for the transcoding that i am doing on Compressor, SHOULD I USE 23.976 or 23.98?
