You have to use the file menu, Import, then navigate to the folder where your CinemaDNG's are located and select the first frame, all this information is on the first link, it describes the entire process in one place or an other. Theres a small bug where the "footage" imported is interpreted at 1fps, however all you need to do is re-interpret the footage as the frame rate you recorded in, and this can be done en-mass so its not a massive problem
