![]() ![]() Most user-operated devices come with multiple codecs so you can easily share videos even to increase compatibility and shareability. ![]() Other common uses of codecs come in the form of security systems’ IP cameras, DVD players, and digital cable. While we won’t get too much into the details now (see our next section for more detailed information about common video codecs), we just wanted to point out that it’s a common part of your everyday life. Starting with iOS11 in 2017, Apple began using the HEVC codec so your device can stream ultra HD 4K video. If you’re an Apple product user, each new iOS comes with a set of audio and video codecs. Where do I see Video Codecs?Ĭodecs are such an integral part of our digital world that you probably use one every single day yet don’t know it. But there may be container specific codecs, like ProRes which is usually only mov. So, in practice, you may have H.264 codec inside mov container or mp4 one. mp4 that you will see on the end of the file. Think of the codec as the software that compresses your video file and container as the box(container) that holds your file. One more thing, there is a codec and there is also something called container. The same code it uses to decompress the file is also capable of being read to decompress the video so you’ll be able to watch the video in full definition. That’s where the other aspect of the video codec comes in. However, only compressing the video would render a low-quality file for you to watch and would impact the audio and image elements. A video codec will take this massive file size and code it into a much smaller file for your device to download. If a single frame in full color is about 8.3 billion bytes, then, at an average of 30-frames per second, it would make that one minute of video 14.94 GB. Take, for example, a minute of high-definition video. A codec is a compressor/decompressor software or hardware (taking the “co” and “dec” from both words to form a shortened one.) Thus, a video codec is a software that compresses and decompresses raw video files on any device you use to watch and transmit videos.īecause most video files carry massive amounts of data, a video codec will compress the file, making it easier and faster to download and send over broadband networks. It’s important to begin by defining what a codec is and how it relates to video. ![]()
