The Video Codecs Abstract
A video codec is the technology that compresses massive raw video files into manageable sizes for streaming, broadcasting, and storage. Without them, the digital video world as we know it—from YouTube to Netflix—would be impossible. This explorer demystifies how they work.
The Compression Imperative

How Video Compression Works
Modern video codecs follow a sophisticated, multi-stage pipeline to intelligently remove redundant data. Each step plays a critical role in balancing quality and file size. Click through the steps below to explore the process.
The Evolution of Efficiency
Roughly every decade, a new generation of codec emerges, offering about double the compression efficiency of its predecessor. This relentless innovation has enabled the jump from grainy VCDs to stunning 8K streaming.
Modern Codec Showdown
Today's leading codecs offer different strengths. H.264 provides maximum compatibility, while newer codecs like HEVC and AV1 deliver superior efficiency for 4K/HDR content, but with trade-offs in complexity and licensing. Explore their characteristics and performance below.
Codecs vs. Containers: What's the Difference?
A common point of confusion is the difference between a codec and a container format (like .MP4 or .MKV). A simple analogy helps: the codec is how you pack a gift to make it small, and the container is the box you put it in. A single box type can hold gifts packed in different ways.
