one way to think is that the timecode point is the bit 'between' the frames. So 01.00.00.00 is the bit after black and before first frame and if you want a 1 frame edit your out point has to be the timecode between the first and 2nd frame (i.e. 01.00.00.01).
Avid lets you mark a single frame with an in and an out... other systems require you to roll onto the 2nd frame to mark the out and have a 1 frame duration.

That one frame difference is a constant point of confusion when people use edls and then type those numbers into avid timelines and see a duratin 1 frame greater. Frame 0 is a frame was the way to phrase it which makes it valid to subtract the frame before the first frame. Thanks.
