Description of Ellie's filming

The script says this for what Ellie will be filming-

Ellie walks up to her house, presumably from school staring at/texting on her phone, with a backpack on one shoulder. Whatever shots are possible from the “perspective of the kidnapper” could be like someone watching her get out of her car, following to the door, etc. Also maybe get an establishing shot of the car pulling in. 

Then, there’s a twig snapping, with one POV shot jumping to where they can’t see Ellie anymore (like they’re hiding). Ellie turns around, looks for a minute, then goes to open the door. POV shot jumps out from hiding and gets close to Ellie’s face, she turns around, drops her backpack with surprise and it zooms in on her eye so we can keep the whole eye to missing poster transition. This way, too, the detective can say something about how the door was left ajar.
