MC in the first frame

Hi!
I have a MC in it’s layer at the first frame and this MC has a scaling code (scaling down) and works fine. But I have more layers i different frames of the scene. When I put more frames for my MC with scaling down, it’s not very smooth any more.
Is it possible to have this MC in the first frame of it’s layer and still make it visible through the whole scene?

Thanks for your help :}
