Shaking in panning , fade in and fade out


Am from Chile, my english is not the best, but i tried to do the best.

My question is ¿why the pannings and the fades, shaking the elements of animation? this happend in harmony, animate pro, inclusive in the toonboom studio.

You can see this in the first 10 seconds of this animation …look to the rocket and the book…is not smooth.

or this

In others software, this do not happend
