Transcode Media for Efficiency in Final Cut Pro

To improve performance and stability, it often helps to transcode the media in Final Cut Pro. The transcoding process creates a new version of your media encoded with ProRes, a codec designed to guarantee higher responsiveness during editing operations.

Right-click on a clip to display its contextual menu

Select "Transcode Media…"

In the Transcode Media dialog, enable "Create optimized media" & click OK

When the "Create optimized media" option isn't available, it means the clip is already encoded in ProRes or that it had already been transcoded on a previous occasion.

Transcoding can be done on individual clips in the Browser or on all media in an Event.
