[Avid-L2] Time Code Effect Misreads Aux time code on Video Mixdown?

 

Here's a quirky one.  When I online I always have a video Reference up on V20.  I usually prefer a video mixdown from offline as opposed to having to take the time to import a screener .mov etc...  The networks are now asking Post to provide a road map for textless elements at the end of the reel after the show.  I've adopted the practice of always cutting in the reference video into the sequence when pulling textless elements so I figured I could just use the time code effect with one display set to master time code 1 and the other to V20 time code.  I have come to find that even though I can see the time code for video 20 in the time code window in the Avid interface the time code effect will not read it as source code.  Kinda strange but my work around is to add an aux time code to the video mixdown and then set the second time code display to other counters V20 aux time code 1.

This aux time code has worked but I found on my current timeline it was off by 50 seconds.  It turns out I had cut the time code effect into the sequence after the start of the 23.976 sequence.  I had cut the time code effect in at 59:50:00.  The sequence bars begin at 59:00:00 which is the first frame of the sequence.  The result was the Aux 24 time code 1 was 50:00 seconds off.  When I extend the time code effect to the actual sequence start then the Aux time code reads correctly.  I guess in my previous sequences I'd always had the time code effect span the entire timeline.  It is curious that other time codes aren't effect this way but aux time code added to a video mixdown does.  What is it about the time code of a video mixdown that it won't show up as source time code in the time code effect?  And what's the deal with the miscalculation of the Aux timecode on a video mixdown?  I'm not stuck but curious what's going on under the hood just for curiosities sake.
