Hi there -
Correct, $2,999 is for the base unit, you would still need the X4S or the X5S.
Yes, to record in 5.2K you would need either the CinemaDNG or Apple ProRes licenses, or both.
A Premium Combo includes the X5S along with both of these licenses at $6,198.
Feel free to reach out if we can be of any further help with anything,
