If the Cutscene flag is enabled, the player can move the analogue stick or the mouse to rotate the cutscene camera on his own within a certain range.
To control which max ranges are allowed at which time, follow these steps:
Cinematic_CameraLookUp
Cinematic_CameraLookDown
Cinematic_CameraLookLeft
Cinematic_CameraLookRight
Cinematic_CameraDoNotCenter
Now you can set values in these tracks for each of the four directions. The number you'll set will be the amount of degrees the camera can be moved beyond its default position for the respective frame.
It is possible to "animate" these values, e.g. you could slowly decrease a value to 0 to make it less obvious that it gets disabled at a certain point.
