Web app that answers questions by cropping and combining YouTube videos

A high-level workflow of what I imagine the app doing looks like this:

  1. User types in question (Eg: What is bubble.is?)
  2. App searches this text on YouTube
  3. Youtube returns several results
  4. App combines a few of those results into one 30 second video and displays.

I have no idea how one would start this in bubble.is. Could you point me to the right resources / links / example apps that do something similar?
