I was playing around with the "Defocused Wealth" and "Bokeh" backgrounds in Motion and was trying to crop them to make a quick and easy animated lower third. Only when I did so and then played it back the crop moved about wildly as it played the animation. I tried cropping the object itself and also the group in which it was contained.
So I have three questions about this:
1)Why is it doing this?
2) Is there a way to crop it and not have the edges move?
3) Why doesn't the background on these, or other animations like these, move about when it's not cropped?
