Negative SMPTE timecode drop-frame handling? How are negative timecodes handled with drop-frame:


Is the frame before -00:00:59:29 labelled -00:00:01:02 (symmetric), or
Is the frame after -00:01:00:01 labelled -00:00:59:28 (regular)?


Thanks.
I know this is a very old Q, but it should be pointed out that a 'negative timecode' makes no sense. The SMPTE frame before 00:00:00:00 is 23:59:59:29. The namespace for drop frame (and non-drop) codes is already well-defined -- no need to postulate negative values. If there are systems or programs that use this notation, they should be rethought.
