You need basically 2 important things to do it with one keyed Cam to make it easy:
1. A camera-lock toolbar script to avoid agry neighbours to f*-up all your cam keys by bouncing their head on the table because CoronaCam still does not shift correctly (especially usefull when having a 3D mouse)
2. All keys at frame 0 to be set to default values and position/rotation 0/0/0 So everytime you should forget to turn on Autokey you could always go to frame 0 and reset stuff
And now that we do not have to switch constantly between CoronaCameraMod and PhysicalCam for keying in the stack (using CoronaCam) it has become easy to operate.
Good Luck
