Re: [Avid-L2] Sony A7_2 MP4 media in AVCHD with XAVC Variable Bit Rate Media?

 

What version of MC is your AE working in? Could this be a relative to the same bug infecting the Canon XAVCS footage in the most recent version of Composer?

Our AE is having problems with some footage from a Sony A7_2 camera.  I'm wondering if it is XAVCS.  I don't know how to check for that but the files will play in QT 10 player but not in QT 7.  In QT Player 10 the info says AVC coding.  Here it the info provided by Media Info.  Can anyone point to any of this data that would indicate XAVCS.  Is the fact that it is variable bit rate and indication it is XAVCS?
