Detecting Shot Changes with the Video Intelligence API

Detecting when a shot changes in a video is a foundational step when it comes to video indexing. Google Cloud Video Intelligence API is capable of processing digital video to output the beginning and ending time code, demarking individual moments taken by a single camera and representing a continuous time and space. In this lab, you'll use a Python script to process a digital video with the Video Intelligence API's annotate function to output a series of individual shots and then compare the timestamps to the original video.
