Clear the 'blue glitch'?

Im making a movie where at one point a Koala Bear sets fire to a forest

And Im making the camera "get a good look at 'forest'"
And there are multiple forests so it looks like this:
camera get a good look at forest
camera get a good look at forest2
camera get a good look at forest3
camera get a good look at forest4
etc etc

So with all the zooming out and the zooming in, the blue background obstructs most of the view.

Any ideas on how to get rid of this?

The default duration for any command is one second. Set the duration of the "camera get a good look at ..." commands to zero and the camera will switch almost instantly from one scene to the other.
