I’m unsure why you would need AE for this, why wouldn’t you just zoom in camera?
If you need AE to do this, it would just be a matter of setting some scale keyframes. Press “S” to open the scale parameter, press the stop watch, move forward in time and adjust the scale for the “push”. Remember that when you scale over 100% you lower quality/resolution. Generally I don’t like to scale more than 120-130.
Also, you can animate the anchor point too. By adjusting the anchor point, you adjust where the image scales from. So before you set you scale keyframes, press “P” to activate the pan behind tool and you can move your anchor point to place you would like the camera to scale from. Then you can move to where the scale needs to finish, press “a” and manually use the numbers to slide the shot to it’s new position. This is also known as the Ken Burns effect.
