[DFBHD] end. file like campaign missions

[Creator]

I'm trying to figure out how to create end. files like those of some missions of the campaign, so that the camera makes more rotational movements and seems to be connected by more than two points and not only by the CBEGIN and CEND that is only two points that create a rectilinear movement.
To better understand look at the end camera of Shattered Palace, Diplomatic Immunity and Irene missions, how can I create similar camera movement?
I tried to open the end. files of the campaign missions but the content is not readable. Help...
