If you are shooting with a Sony Alpha A7S Mirrorless Digital Camera, you may have troubles while working its XAVC S or AVCHD footage in FCP X. To resolve this problem, you will need to transcode Sony A7S XAVC S/AVCHD to Apple’s ProRes, the best suited editing codec for Final Cut Pro X, FCP 6 and 7.
“Dear all, I was wondering if you can help please!!! I just have a Sony Alpha A7S Mirrorless Digital Camera on hand. It is able to shoot video files either in XAVC S and AVCHD format. When I attempted to import the A7S footage to FCP X to do basic editing, the FCP X recognized my Sony A7S video streams, I got to check the files to import but when it started to import it suddenly crashed. I have enough memory and all the requirements seem to be ok. Any idea about what could cause the crash? Does that mean I need to transcode them before start editing? If so, which software will you recommend? Any advice would be greatly appreciated. MacBookPro, Mac OS X Mavericks (10.9.2). Thanks in advance.”
