Yes, listen to Marc.
This brings up a pet peeve of mine. Why can't Red correct (yes, I said correct, as this is a big mistake) their GUI to read what the camera is ACTUALLY SET AT.
I have had this discussion countless times on set. Someone notices the "24 FPS" in the LCD display and asks in a panic, "I thought we ere shooting 23.98???!!!" Much explaining about Red and the onscreen GUI happens, and I show them in the tiny print by the "media" info where it says 23.98, but everyone always walks away from the camera feeling a bit unconvinced.
If we set it to 23.98 (which I almost always do; I can think of only one electronic job in my whole career where the producers wanted- and understood what they meant- 24 fps) PLEASE HAVE THE CAMERA DISPLAY "23.9 FPS", NOT "24 FPS"
Arri understood this when they designed the GUI for the Alexa, and it was most welcome. When you are shooting 23.98, it SAYS 23.98.
I would have expected that this would be fixed on Epic but it has not been.
You aquire, capture, call it what you will t 23.98 which is still considered 24fps. Shooting 24FPS with a 24FPS time-base as well is used primarily if you know your are doing a film-out at the end of production. You can still do a film out with 23.98, but all system prefer digitally to use the 23.98 as a standard.
