I have some 4K 16:9 .r3d files shot on Red Epic. Is the 3840 X 2160 image scaled internally on the red epic from the 5120 X 2700 at the time of capture or is the 3840 X 2160 a cropped window of the 5120 X 2700 during capture. Need to know this to set up a CG scene and will make a difference.
Thanks for clearing that up Dave. I know different cameras handle this in different ways. i.e. Arri Alexa. I did the math on the relevant sensor area to use in tracking software. I fed it into PF tracker with my lens info and it tracked very very close. Once again "The Cow' to the rescue.
