Keeping text centered during a transition Beginner to After Effects here. I'm trying to do a basic transition: text starts out at 50% of its size, centered to the composition. After a few seconds I want the text to increase to 150% while staying in the center. But anytime I do this the text shifts. Can anyone help?
Although you can reposition the anchor point with the Pan Behind tool (Y),



an easier way to center it is in the menu. 

Layer->Transform->Center Anchor Point in Layer Content. 

I agree with the other posts here: It's important to set the correct alignment and placing of a layer before you keyframe anything.
