Building In-Video Search

tl;dr: "Suppose it’s Christmas, and you want to create a great instagram piece out all the best scenes across Netflix films of people shouting “Merry Christmas”! Or suppose it’s Anya Taylor Joy’s birthday, and you want to create a highlight reel of all her most iconic and dramatic shots. Creating these involves sifting through hundreds of thousands of movies and TV shows to find the right line of dialogue or the appropriate visual elements (objects, scenes, emotions, actions, etc.). We have built an internal system that allows someone to perform in-video search across the entire Netflix video catalog, and we’d like to share our experience in building this system."
