Eastman 5222 (Double-X) film does not have to be developed in a special developer D-96. Motion picture film is typically developed to a lower Contrast Index or Gamma than still films hence the use of a softer developer. The reason for this is because prints are made on positive stock which is fairly contrasty. For still use you can use any film developer you wish.
I prefer to rate 5222 at an EI of 400 outdoors to get a bit more contrast and have used Rodinal 1+49 @ 21C and HC-110 1+49 8.5 m @21C. Because this film is on a thicker base it dries flat and tends not to curl.
Kodak lists an RMS Granularity of 14 (very file) which makes it finer grained than Tri-X RMS Granularity 17 (fine).
