This is a 9 part seminar by a TV editor from Australia. each lasting nearly 10 minutes. It is worth watching to understand colour correction and why. The guy also explains about the scopes available on Final Cut Pro. ( not FC Express). Vital information here about the TV standard and limits..... worth watch all 9.
