i'm doing a zoom on picture of woman face
but when the scale values get higher,the x,y position got changes lot
and it's like my zooming is shaking to get right to final posiition like one of her eyes
( i think you will understand when you do scaling pictures up )
i tried deleting the keys in the middle ,still not good
Is there any formula for doing big zoom like this?
thnx

I don't have a problem with zooming as long as my base picture is hi-res. If I do I use a slight motion blur which looks natural most of the tinmes.

You should check that your anchor point is placed in the right spot (your focus point -> the spot to where you zoom)

Alternatively, you can use a 3d layer and animate a camera. It's one of my favorite methods of doing clean zooms & pans.

Animate the anchor point in unison with your zoom. Scaling is a proportional transform and for smooth results the number of pixels in the visible area should be pretty constant.

you could also try using the exponential scale keyframe assist... works for me if you want to keep everything 2d
