Apple’s Final Cut Pro X Introduces Third-Party Workflow Extensions
Apple will let Final Cut Pro X users bring third-party apps and services directly to the software’s editing interface with the addition of third-party workflow extensions.
What is New?
Workflow extensions match the look of Final Cut Pro and integrate tightly into the app, allowing editors to drag media into Final Cut Pro libraries, sync playback between extensions and timeline, add clip markers and more.
