Re: [Avid-L2] Audio Stems Time Code Wavs read differently in Avid vs. Wave Agent?

After the mixer said I should just change the wav time codes using QT change instead of him fixing them, I assume he would have to re-export, I've been playing around with QT Change and Wave Agent on these WAV files.  I've fixed them but I'm curious about some of the things I see bouncing between Wave Agent and QT Change.  The start time code change is straight forward in QT Change.  Then when I bring those files into Wave Agent I have to tell Wave Agent the files frame rates are 23.97 ND and then it reads the start time code correctly.  If I then save this change in Wave Agent the files will come back into Wave Agent knowing they are frame rate 23.97 ND.  This makes sense to me.  Is it correct that the wav files came out of protools with no Frame Rate metadata?  Bouke had mentioned ProTools is very lacking in generating wav metadata so I assume this is what is going on.

My other curiosity is that at the desktop level the wave files are discrete left and right individual files but in Wave Agent it sees them as Interleaved Channels = 2(MONO) and in the case of the 5.1 stems Wave Agent sees them as Interleaved Channels = 6(MONO).  If I alter the time code start of a right or left stem it breaks the 2(MONO) to 1(MONO) until I set the file back to matching start time codes.  This makes sense but I'm wondering given the files appear individually on the desktop what aspect of these seemingly individual files is tell Wave Agent they are in fact Interleaved?

So many widgets spinning in a circle.  I've accomplished the goal but as all too often the more I think I learn the more I realize how much I don't know.
