Optimized vs. Proxy Media
Software: Apple FCP X
By default, Final Cut Pro X displays, edits, and outputs camera native files, unless you created optimized files; in which case it displays optimized media. But what if you want to work with Proxy media?
Click the small switch icon in the top right corner of the Viewer and change it to Proxy.
Keep in mind that whatever you have selected here is what you’ll Share during export.
