UPDATE: FCPX 10.1.4 now includes support for .MXF files, making this article redundant.
(and my purchase ).
Currently (Oct 2014) I have not found a working plug-in for FCPX to import Sony .MXF files, which is the format produced by many of Sony’s pro camcorders.
I have however found a number of ways to overcome this:
HandBrake – is free open source video converter. It is not the easiest to use, but is free and produced acceptable .MOV files from .MXF files. You can the create optimised media (aka ProRes422) in FCPX.
Sony Catalyst Browse – <RECOMMENDED> is a free program from Sony. It can transcode .MXF files to ProRes422, one at a time. But you can start (manually) multiple jobs and they will queue up.
Sony Content Browser 2 – US$20 from Sony. Does basic editing and export to FCPX using XDCAMHD422 codec. Doesn’t offer batch processing.
aPubSoft MXF Converter – $29. Produces Apple ProRes422 files and has choice of parameters, such as frame rate and resolution. Has batch mode processing. Also handles other input/output formats, such as Panasonic and Canon, etc.
