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

You have to Uncheck 'preserve start TC' in Wave Agent.

Then you'll see that it will show the right TC values.

Note, Wave (BWF) does NOT have TC, but samples after midnight, starting at 1

So, TC 00:00:01:00 is written as 48001

That can be calculated to TC.

BWF can also have metadata indicating the speed that was intended.

Note that both values you see are perfectly allright!

You can also try QT change, that will work on BWF (and MXF) nowadays.

I think this is a Bouke question.  I got some mix stems back from ProTools that don't match my sequence time code.  The first stems I got for mix approval match with proper time code but a subsequent export of the rest of the mix stems don't match.  Something got flamuxed in mix land which I will get them to straighten out.  In checking the new stems using Wave Agent to see the time code I found that the time code Avid shows in the bin does not match the time code I see in Wave Agent.  My project is 23.976 which I assume is how the protools session is set up.  All other stems for previous episodes have matched but even the ones that match correctly in Avid show a different time code.  It looks kinda like a NDF DF offset but in 24 frame land.  My limited understanding with Wav files is there is metadata for a start time code and I may be incorrect about this.  Clearly Wave Agent interprets the time code differently.  The correct stems start at 00:59:59:00 in Avid but start at 01:00:02:17 in Wave Agent.  I tried the pulldown menus to set the frame rate to 23.976 but that didn't change the Time Code Wave Agent is displaying.

Looking to refresh and learn more about how and why different apps read out the time code differently.  I also tried Audacity but it doesn't seem to have an option to read time code, or I just don't know where to look.  I did drag the wav files into my Media Info App which displays various metadata but it didn't detect a time code track on the wav files which I assume is an indication that wav files don't have an actual time code track like a .mov can and other file formats.

Not a mission critical problem but I am curious for whom the Time Code tolls?
