MPEG HD 422
is an 8 bit HD only codec that has been
used for HD television production for a very long time.

using older editing hardware. It is still very popular with
many broadcasters because it is very easy to work with.

choice where the priority is to have maximum backwards
compatibility or when editing using older low powered
computers.
