Why are you answering this thread if you do not know? lol
Are you one of those people calling your self professional because you got a expensive camera with time code you never use or need to synchronize anything for film or TV?, well let me tell you that its not a thrill to work for other people unless you love it and do what you like, if you are told what to do its not at all fun, why the hell wanna be professional exists beats me, but whatever we all did this before i guess.
Listen the 5dmkiii dos have a problem with time code, any changes you make to it are un responsive unless you shut off the camera and turn it back on, this is another bug on canons part, why we have to wait until april for a update is just a scam, canon seems to be obsessed with competing with their own higher quality cameras rather then the market itself, i hope they stay in tune and do not fall off a clif.
