Codec stands for compressor (CO)/decompressor (DEC) pairs. You use different codecs for
different playback methods (such as the web or DVD). Once you know the playback
method of your target audience, you can pick a suitable codec. To decide which codec
is right for your needs, you must choose the necessary level of compression to meet your
data rate limits and the level of quality you want.
