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, , 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.
