Came upon troubles on your Mac while editing Sony A7 MXF files in Final Cut Pro X after upgraded to High Sierra? Actually, there are a number of users having the same issues. To solve these incompatibility issues, you could convert Sony A7 MXF video clips to Apple ProRes codec first before you start editing in FCP X.
“Hi guys, I’ve been struggling with one problem none has been able to fix so far. I’m editing some MXF files coming from a Sony A7 through FCP X. For some reason the Sony A7 .mxf files are imported without any audio. I have processed a lot of Sony A7 MXF videos in the past without any issues at all and I’m following exactly the same procedure – the only change is that I have updated my OS to High Sierra. This is really strange and I’m wondering if it’s related to some update in FCP X and if anyone else has experienced a similar issue. Any help would be greatly appreciated!!”
This is a known issue between FCP X and macOS High Sierra. One solution is transcoding Sony A7 MXF media to ProRes codec first, then import into FCP X. Check a guide on how to process Sony A7 MXF to ProRes conversion for FCP X editing.
To transcode Sony A7 MXF video files to ProRes, do as below:
Step 1: Start up Video Converter for Mac and click “Add File” to load Sony A7 MXF video files that you need to convert into this program. This converter supports batch conversion, so you can import a bundle of Sony A7 MXF files into it to do conversion at a time.
Step 2: Click “Profile” to select output format.
We would recommend choosing “Final Cut Pro” > “Apple ProRes 422 (*.mov)” as output format. Apple ProRes is FCP X’s favorite editing codec, which FCP X will recognize and handle well.
If necessary, you can click “Settings” button to modify video and audio parameters like encoder, resolution, frame rate, bitrate, aspect ratio, sample rate, and audio channels. You can also “Enable 3D Settings” to add 3D effect to your source media.
Step 3: Start MXF files conversion.
Click “Convert” to start Sony A7 MXF files to ProRes conversion.
As soon as the conversion is complete, click “Open Folder” to get the generated files for editing in Premiere Pro on your Mac with optimum performance.
