FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A codec (the term is a mashup of the words code and decode) is a computer program that uses compression to shrink a large movie file or convert between analog and digital sound. You might see the word used when talking about audio codecs or video codecs.

Detailed explanation-2: -Codec is an acronym that stands for compressor/decompressor or coder/decoder. It is an encoding tool that processes video and stores it in a stream of bytes. Codecs use algorithms to effectively shrink the audio or video file size and then decompress it for playback, editing, or when needed.

Detailed explanation-3: -What’s a codec? A codec compresses or decompresses media files such as songs or videos. Windows Media Player and other apps use codecs to play and create media files. A codec can consist of two parts: an encoder that compresses the media file (encoding) and a decoder that decompresses the file (decoding).

Detailed explanation-4: -You may have heard the phrase video codec when referring to video files. A codec is simply the software that compresses your video so it can be stored and played back. It can digitize and compress an audio or video signal for transmission and convert an incoming signal to audio or video for reception.

Detailed explanation-5: -In other words, the more you compress, the more quality you lose. Lossy compression technologies use two types of compression, intra-frame and inter-frame compression. Intra-frame compression is essentially still image compression applied to video, with each frame compressed without reference to any other.
