| So, for the curious (someone has to be curious since a google search brought up a ton of similar questions and no real solid answers) I came up with at best a solution, or at least a workable workaround.
My issue was that I was concatenating a bunch of QT movies together to insert blacks, slates etc onto a master file and outputting a complete version. The resulting concatenation resulted in discontinuous timecode. My solution was to, after the cat, delete the resulting timecode track and load a premade TC track (I needed everything to start at 01:00:00:00) I created by exporting a movie from Final Cut Pro and deleting the video track. I made sure that the TC file was a .mov that was longer than any possible permutation that I might have. I stuck that file in my bundle.
Then, after doing all my pasting to get my finished file, I got the duration and time scale of the finished movie, opened the TC movie and got it's duration and time scale and calculated the length I needed to select. using
select at 0 to (tcTimescale * (movieLength + 1)) / movieTimescale
To select the TC track at a length to match the finished movie (the +1 ensures that I don't come up short in rounding error) and pasted the new TC track into the movie after deleting the old one. Voila! Continuous TC from the beginning at 01:00:00:00.
Dunno if anyone cares, but this has been a thorn in my side for awhile.
Cheers,
Steve

Does anyone know how to create, replace, regenerate or modify a QT Timecode track?
I've edited together a number of clips into a single QT movie successfully, but those clips all had TC starting at various times. Now my resultant QT movie TC jumps at each edit, resulting in discontiguous timecode.
Once I've concatenated all my video, I'd like to delete the resultant TC track and replace it with a new one, starting at 01:00:00:00. This is all ProRes 23.98 material, but I presume that any solution could be adapted for any frame rate.
A lengthy search has resulted in lots of info about creating text tracks, for chaptering, etc, but I can't figure out the Timecode track issue and if there is a relationship.
Thanks in advance.
