FCP X issue with Sony DSC-T7 AVCHD footage

Final Cut Pro X won’t import Sony DSC-T7 AVCHD mts files after the upgradation to macOS High Sierra? Actually, this is a known issue. Before Apple releases a fix for the problem, you can solve the issue via transcoding Sony DSC-T7 AVCHD footage to Apple ProRes codec encoded QuickTime MOV format first before you start editing in FCP X.

How to transcode AVCHD mts files to ProRes for FCP X editing

“Hi there, my client handed me a drive with .mts clips copied off the Sony DSC-T7 with no folder structure. FCP X got stuck in dealing with these .mts clips. Do I have to convert them first for a smooth workflow? Thanks for any advice.”

Actually, the AVCHD folder structure is the “container” for the video. It is the “cassette”. Tell your client to stop that and give you the entire AVCHD (or whatever root folder) on a hard drive. Have them put each AVCHD folder into a nicely named folder so you know what it’s for. In your specific case, you could convert bare MTS files extracted from the Sony DSC-T7 AVCHD folder to an editing friendly format (e.g. ProRes) for FCP X first.

Step 2: Choose output format for FCP X from “Profile” list
Working well as an Sony DSC-T7 AVCHD converter app, Video Converter for Mac comes with a flavor of Apple ProRes codecs , including Apple ProRes 422, Apple ProRes 422 (HQ), Apple ProRes 422 (LT), Apple ProRes 422 (Proxy) and Apple ProRes 4444. For a good balance between quality and file size, we would recommend choosing “Apple ProRes 422 (*.mov)” as output format under “Final Cut Pro” column. The ProRes 422 codec will ensure a good performance working in FCP X even on an old Mac machine.

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.
