Dear DD,
Thanks for your workaround, the problem is that Cannot Open can be a standard Mac response to any number of issues it has. I assume in the Cannot Open you were seeing warnings about individual files. As we are sending to PT it might be easier to generate proxies of the Sony MXF files.
We all here do appreciate that X2pro was more tolerant but it was using the old code base which was more open which is one of the reasons Apple insisted we moved to the newer code base.
We have to use Apple’s own AVFoundation to open up MXF’s and it does not like all flavours of MXF, previously we could use QT and what ever we wanted.
If you have a sample of the Sony media you were using, we would be happy to look at it to confirm it is AVFoundation.
Yours Sincerely
James.
