Why does all timecode start at 1 hour? (01:00:00:00)



Is there a reason timecode in Final Cut 7 and timecode in Pro Tools starts at the 1 hour mark? eg. 01:00:00:00? As opposed to all zeros? Some old broadcast standard that I don't know about?

You can change it to all zeros by going to Sequence>Settings>Timeline Options>Starting Timecode and change the 1 to a 0.Murphy 2017-01-10T19:04:59.713



It's to leave room before first picture, for slates, countdowns, test signals etc, while still preserving an easy count of running time for the video. Yes, it traces historically to broadcast and in particular videotape.

Many tape-based editing systems couldn't deal with 24-hour wraparound, so the next even hour became traditional 'time zero'. I suspect that most non-linear systems are the same.

Starting at 10:00:00:00 is also widely used.mivk 2015-11-22T13:52:22.380

This is correct, because typically a leader starts at 00:59:50:00 and your two pop is at 00:59:58:00Chris James Champeau 2013-04-01T18:41:54.930


Some projects use the hours field as a reel/tape/memory card indicator. Many cameras permit setting the TC hours number arbitrarily to support this usage. You could set the hours number in Pro Tools or FCP to conform to such a system if required.
