Netflix analyzes BILLIONS of frames from every show and movie using cutting-edge computer vision. Here's what they can do with it that you never knew about.

In this video, I break down 3 mind-blowing algorithms Netflix uses:
- Match Cut Transitions - How they automatically find perfect scene transitions
- Video Search - Search for "exploding car" across millions of hours of content
- Scene Detection - AI that knows when a scene changes better than humans

You'll learn about instance segmentation, optical flow, embeddings, and how Netflix saves thousands of editing hours with these tools.

Coding with Lewis

Netflix uses three sophisticated computer vision algorithms to analyze billions of video frames: match cut transitions that automatically find visually similar shots for seamless editing, video search capabilities that convert text queries into mathematical embeddings to find specific scenes, and scene detection that combines screenplay alignment with multimodal analysis of video and audio tracks. These systems leverage instance segmentation, optical flow, and bidirectional neural networks to automate video editing tasks that would otherwise require thousands of manual hours.
