I don't know if this is the same process, but on a movie several years back, probably, 7 or so, we used a kodak system that was probably the forerunner.
This is a system. You have to follow the system to allow for the film to look like the video (digital) camera.
If you're shooting video, I don't really see the need for it. You're seeing what you shoot on a monitor. With film you can't, hence the reason to use a digital camera to shoot the scene from camera POV using a system that allows for you to see the colors and some sort of contrast ratio. You don't need a Digital intermediate. You already have one.
