Customizable camera moving routes

Users can draw three-dimentional routes for camera moving in the designer,it can set the movement's speed?directions and where the camera is looking at ,and use inputs which were set to let cameras move in the route player set at flight mode.
This is an idea for our video creators,inspired by the model cg video made from blender. It can make better camera moving shots than mechanical (pistons,rotators) or vizzy camera movement.
