Apple has released Final Cut Pro X 10.0.7 with a small grab bag of fixes to improve stability and performance. Amongst the tweaks, the update restores the Letterbox effect “Offset” slider, fixes a problem with uploading clips to Vimeo larger than 1 GB in size, and fixes an issue in which an incorrect frame size is used with filters on two adjacent clips with different pixel aspect ratio. It also deals with an issue where some third-party effects caused the app to stop responding during background rendering and another where third-party transitions incorrectly used black instead of source media.
