SUMMARY
=======
 
This article provides a method for simulating the effect of multiple
cameras in a scene.
 
MORE INFORMATION
================
 
Set up a series of nulls in the location where you want the camera and/or
the interest at the different frames during your animation. Then use the
DopeSheet to activate and deactivate the camera to the various nulls for
the relevant frames. This will give you instant cuts.
 
The following is an example of camera movements only. However, the same can
apply to the interest's movements simultaneously.
 
1. Get three nulls and translate them at various positions in space.
 
2. Constrain the camera to all three nulls.
 
3. With the camera selected, open the DopeSheet and expand the animation
   tracks by clicking to the left of the green bar.
 
4. Select the areas where you do not want the camera to be constrained to
   null 1 by dragging the white box over the relevant frames.
 
5. Click on DEACT in the top menu display of the DopeSheet to deactivate
   the selected area.
 
6. Repeat steps 1 through 6 above for the other two nulls.
 
Keep in mind that when a frame range is active (camera is constrained),
there should be two deactivated nulls for the same range of frames;
otherwise your camera will be constrained to two nulls at one time.
