Re: [Avid-L2] Can't update video properties in QT7Pro when files is on a network drive?

[Edited Message Follows]

I agree.  I've been using QT Ref just to get out of Avid and then do a save as because current Adobe Media Encoders no longer support QT Ref.  Unfortunately now I find that AME will no longer export a QT .mov with XDCam50 or any other XDCam flavor of codec.  It use to do that on my work system.  Perhaps I'm missing something in AME but I only see XDCam codec choices in the mxf op1a exports.  Fortunately I found that I can do a custom Avid QT export on my 10.12.6 Mac OS startup with MC 2018.12.12 and choose XDCam 50 24 422 in the QT custom settings.  Some new behavior to me was even though the QT Engine custom audio settings don't offer 12 channel discrete audio as a choice it turns out Avid in direct out audio format overrides the QT custom settings.  I got a prompt during export that said this and my resulting file did have 12 discrete mono tracks.  I was happily surprised to see the video levels in this workflow match the original sequence when I ama link to resulting file.  There is an ever so slight change on vectorscope and double diamond but I'm talking virtually no change.  It's much less than the old politically incorrect metric of the size of hair.  ;-)

Other than the suggestion of FCP7 I'm sure there must be other software that could take an Avid exported mxf op 1a file and create an XDCam50 .mov with 12 channels of audio but I've yet to hear one.  I would think FFMpeg could do this I'm just not a command line guy.  Perhaps the software front end FF Works would make it simpler to set up in FFMpeg if FFMpeg can do it.
