"I have some videos—shown as XAVC files from a Sony f55, the files are really good in quality, high definition indeed, or rather, the true 4K videos. but the problem is, I need to edit them in programs like FCP, but how can I do with these xavc firstly? I google some apps, but only come with bad video effect, so, can you please offer some tips to help me out? Thanks."

The Sony f55 features 4K XAVC output signal is debayered and converted to three 4K components which are recorded internally on to the CF card, as well as HD. The 4K is recorded as Motion JPEG while the HD is recorded as H.264. The video tracks are stored in a MOV file format. The picture editor we're working with would like the files delivered as ProRes 422 1080x1920p. So I need to merge f55 4K XAVC MXF to FCP ProRes422 MOV. But I got some problem with 4K footage.

Moreover I can also convert 60p/50p H.264 HD MOV to Apple ProRes , the most compatible video codec with FCP, then these Full HD MOV files supported by FCP will be easily achieved. As a multiple video supported conversion tool, iMedia Converter for Mac can also help me convert 4K video in MXF, XAVC and AVCHD format.
