Shaking in panning , fade in and fade out

Hi:

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 https://www.youtube.com/watch?v=rT3QVJa0bkI …look to the rocket and the book…is not smooth.

or this https://download.toonboom.com/files/products/studio/tips-and-tricks/camera-effects/index.html

In others software, this do not happend

Thanks
