Description

The industry "bible" is back and it's better than ever. The Art of Digital Video has served as the ultimate reference guide for those working with digital video for generations. Now this classic has been revised and re-written by international consultant and industry leader John Watkinson to include important technical updates on this ever-evolving topic.

The format has also been improved to include optional sections that provide additional information that you can choose to skip or investigate further, depending on your interests and comfort level with the subject. As the worlds of film, digital imaging, and computing have converged, this book has evolved to remain current and relevant, while still remaining the classic that experts in the field have trusted for years.
