Some of these methods are called chroma subsampling, quantization, and spatial/temporal downsampling. Other methods look at movement and use mathematical prediction to reduce the need to store every pixel. These methods include detecting when certain areas of the video don’t change from frame to frame, allowing you to toss out certain data. Modern video codecs use many different mathematical methods to reduce file size. They “throw out” certain data to make video files smaller in size, while trying to retain as much quality as possible. At their core, a codec is a video compression method. However, at thirty frames per second, the amount of storage space necessary for digital video grows very quickly.Ĭodecs, which is short for “ coder-decoder,” were created as a solution to this problem.

Raw video is composed of a series of still images played one after another. What is a Video Codec? Video codecs are essential to web streaming. What is the Best Video Codec for Streaming?.We will discuss the optimal settings for this codec and review some of the next-generation video codecs to look out for. In this post, we’re going to give you a little bit of background on codecs before we discuss which video codec is best for web streaming in 2021. Codecs are important, but they can also be a bit confusing. This technology is what makes it possible to stream over the internet. That said, codecs are important for HTML5 video streaming. Although your online video platform will take care of most of the technicalities, it’s still good to have some idea of what is going on behind the scenes. However, setting up advanced, high-quality streams does require a small amount of technical knowledge. Getting started with live streaming is easier than ever.
