jpeg will always be lower quality, but easier to store and share. For that reason, a raw image converted to. Lossy codecs discard unnecessary data and reduce quality where possible. Lossy compression, on the other hand, gets rid of data.

zip file without compromising the data integrity, for instance, you’re employing lossless compression. Lossless compression involves compacting data without discarding any information. For that reason, these video compression standards are two-trick ponies: They facilitate both the encoding/compression and the decoding/decompressing aspect of video streaming. Literally ‘coder-decoder’ or ‘compressor-decompressor,’ codecs apply algorithms to the video and create a miniature version of it. Versatile Video Coding, or VVC, is also H.266 for the same reason.”įor the sake of clarity, I’ll be including both names at first mention of each codec within the subsections of this article. “H.264/AVC and H.265/HEVC have two names because each codec was standardized by both MPEG and the International Telecommunication Union (ITU). H.264, also known as AVC (Advanced Video Coding), is the most common video codec AAC (Advanced Audio Coding) is the most common audio codec.īut wait - why does H.264 also go by AVC? And how are we to sort through so many confusing acronyms? Streaming codec expert Jan Ozer explains it: Streaming requires the use of both audio and video codecs. 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 videos 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.

Popular software options include Vmix, Wirecast, and the free-to-use OBS Studio. Video encoding is essential to live streaming, helping to ensure quick delivery and playback.Įncoding can occur within a browser or mobile app, on an IP camera, using software, or via a stand-alone appliance. 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.
