Apple's update  comes seven months after the firm first unveiled Final Cut Pro X, which was replacing Final Cut Pro 7. It brings back many of the features that had been shelved with the new version including multicam editing and in-app chroma keying.

Version 10.0.3 can now automatically syncs clips from a shoot using audio waveforms, time and date, or timecode "to create a Multicam Clip with up to 64 angles of video, which can include mixed formats, frame sizes and frame rates," says Apple. "The powerful Angle Editor allows you to dive into your Multicam Clip to make precise adjustments, and the Angle Viewer lets you play back multiple angles at the same time and seamlessly cut between them."

Apple has added advanced controls for chroma keying including colour sampling, edge adjustment and light wrap. "You can tackle complex keying challenges right in Final Cut Pro X, without having to export to a motion graphics application, and view your results instantly with realtime playback," according to Apple.

Apple has also added broadcast monitoring to Final Cut Pro X, which, while still in beta, allows editors to connect to waveform displays, vectorscopes, and calibrated, high-quality monitors to ensure that their projects meet broadcast specifications.

To coincide with Apple's update, Intelligent Assistance has also released, today, its 7toX plug-in, which uses XML to import Final Cut Pro 7 projects into Final Cut Pro X. The plug-in is available from the Mac App Store for £6.99 ($9.99).

The update to Final Cut Pro X is available now on the Mac App Store.
