Camera track plays back very slowly from "camera view" but not others.

I tracked a shot, and then automatically set up the scene.

Now when I play the animation, it works fine from any angle except from the camera veiw.

As soon as I press 0, it slows to less that 1FPS

Any idea what is causing this, or how I can fix it?

When you set up the scene did it also set the camera background to the clip you were working with? If so I’d suggest the slow down is caused by it accessing the clip off your disk. Any other view in the 3D window won’t have background clip (unless you view it in ortho).

My computer always slows to a crawl if I have the background video showing in camera view. Hiding it helps speed things up.
