high quality video presentation of our app

We have an app to put simply is a toktok like app in which we need to make a video of high quality to really show off this app for us to present to investors.

Looking for an editor that can take our app and make an engaging video with more then just clipping together screenrecording of the app being used. SOme examples is a hand coming out and grabbing the phone, one part where it zooms into the phone and visually represents the technology going on in the app.
