Alongside the update to Final Cut Pro X, Apple has also made available a new version of the Pro Video Formats extension, with extension of MXF to not just QuickTime Player but other supported macOS applications, plus wider AVC-Intra support.
The update is a sub-point update, and relatively minor. The biggest addition is widening of MXF support with full plug-in and presets for Compressor 4.3 and earlier, and a widening of app support in High Sierra.
In addition, AVC-Intra has been extended to Intra 50, 100, 200, 4:4:4, and LT.
The last update to the suite was in October, 2016. It will only appear as a software update after users have downloaded and installed Final Cut Pro X, Motion, or Compressor.
However, the discrete download is free, is 7MB, and suggested for users who have to deal with Final Cut Pro X workflows.
The update is complimentary to version 10.4 of Final Cut Pro X, which was released on Thursday.
