Changes to these codecs are always happening as technology advances. There are also transformative codecs which cut the video material into smaller chunks before they have been compressed. There are lossy codecs, which lose a small amount of information, although they compress material into a much smaller formats which is ideal for internet sharing. There are lossless video codecs, which always reproduce videos exactly as they were without any loss in quality. There are various types of codecs available for use. Codecs can also be used in a physical piece of hardware, like your camera, turning incoming video and audio into a digital format. Moreover, codecs are computer codes that perform their function whenever the video files are requested or called by a piece of software. Therefore the codec exists for that purpose, because it encodes and compresses the data for storage or sending, then decompresses for playback or editing. So what does that mean for videos? Quite simply, video files can be very large, and they need a way to make them smaller. The word codec is the meaning of two words: coder and decoder.
