Subframe Audio Editing in FCPX

Danny Greer

Edit your audio in Final Cut Pro X with extreme precision – up to 1/80th of a frame!

Want to have more precise control over your audio edits in FCPX?   Nudging an audio clip up or down an FCPX timeline by subframe will move it approximately 1/80 of a frame, allowing you to get meticulous!

This type of precision is especially useful if you’re trying to line-up dialogue during ADR or working on short commercial spots (where every second, and half second counts!)
