So simple yet I cannot find a 'how to'.

I have a medium shot of a woman sitting up in bed. Shes looking worriedly to a window off screen. Her child is asleep, with her head on mom's chest. 

I simply want to start zoomed in, with the childs face filling the screen, then pull back slowly to reveal the mother. 

Lots of tutorials out there on zooming in and out, but not starting zoomed in.

I'm missing something simple. I have both Premiere pro and After effects.

Thanks,

Scott
