Not compatible. This is the new XAVC .MXF wrapper found in the new PXW X-70. 4:22 50Mps 1920x1080. Yes, I used Catalyst......no batch and time consuming.
Believe it or not, I can import the new .MXF wrapper/codec to a Macrosystem standalone editing system but not SONY VEGAS PRO.
Nothing new about the wrapper, it even works with V9. The issue you're having is with the codec inside the wrapper. Get a copy of Catalyst Browse (free) it'll fix it for you.
