Video Encoding | Learn Podcasting http://learn-podcasting.blogspot.com/2008/12/vi... Video encoding is more involved than audio encoding. Raw video files are much larger than raw audio, so a much greater degree of compression is required. Modern video codecs also have benefited from fierce competition between the leading streaming media platforms, as well as the MPEG organization. Most encoding software packages include a number of presets that produce acceptable video quality.

The data signal is combined with a high bit rate code signal which is independent of the data.
