Codecs allow us to tightly compress bulky streams down for delivery and storage. What Is a Codec?Ĭontent distributors use a video compression technology called a codec to shrink a video into a streamable size. To put it more simply: encoding describes the process of compression, whereas codecs describe the means for doing so. In order to compress the raw video into a more manageable size, encoders use video and audio codecs, which apply algorithms to shrink the bulky video for delivery.

When it comes to streaming, videos are often compressed from gigabytes of data down to megabytes of data. Video encoding refers to the process of converting raw video into a digital format that’s compatible with many devices. What does video encoding involve, and how do video codecs work? We’ll dig deeper below and cover our list of the best video codecs for streaming.
