"I plan to purchase the Sony FDR-AX100 4K camcorder that was just announced at the CES last week. It use the same same XAVC-S codec as the already released Sony FDR-AX1. If anyone has had any experience editing this format in Final Cut Pro X, I would be pleased to learn of their experience and the specs of the computer they are using. I am hopeful that editing XVAC-S footage on the new Mac Pro with FCP X will be possible. Thanks in advance for responding."
Work 4K XAVC S with FCP X
Although Apple has officially claimed that the latest version of Final Cut Pro 10.1(Final Cut Pro X) is compatible with XAVC S. However, users from fcp forums still complained that they had no luck to import Sony 4K XAVC S codec from Sony AX-100/AX-1 or AX-33 to FCP X. They think it is actually a lack of FCP X support for the 4K XAVC S codec according to many tests.
Although FCP X does not support 4K XAVC S codec very well, however, it has no difficulty to ingest other video codecs such as H.264 or MPEG-4, especially the Apple Prores Codec, which is specially developed by Apple for high performance and high quality post-production editing in Final Cut Pro X.
