When I started out in the film business 7 or 8 years ago, I watched the crew guys use a "slate" between each take (a digital slate that was synched up with the film camera). I understood the principle: keep audio and picture easily matched together. But I didn't understand what they were doing beyond that. And now that I'm shooting my own stuff (as of 3 months ago) I notice that there are various timecode options in programs like Avid Xpress...but I'm not really sure what purpose they have anymore. Why would I bother slating now? Sound is perfectly synched in my DVX100A (unless I record to a separate DAT, which I just wouldn't do at this point). Is the slate and even timecode dead?
