What is a video codec?

A video codec is a hardware or software based tool for encoding video. Codecs apply to audio files as well as video.

What are they for? Uncompressed video requires hug amounts of storage space. Without video compression it would be close to impossible to store your SD or HD video on tapes or memory cards.

Video picture quality. The rule is normally  that the lower the compression the higher the picture quality. Having said this some of the modern codecs are very efficient at compressing video without picture quality loss.

Video Bitrate. Bitrate is measured in Bits per second of picture information. Broadcast Standard (In the UK) bitrate is 50 mega bits per second. With 4:2:2 colour sampling.
