Final Cut Pro – Green is not just for stoplights
Ever wonder what these green buttons do?

Green Lights
On the left edge of the Final Cut Pro timeline are a series of green buttons, which I call the “green visibility lights.” There is one for each track.
These buttons are enormously powerful, but quite shy — they don’t like telling us how much power they have.
When the green light is lit, everything on that track is visible (or audible). When the green light is dark, everything on that track is invisible (or inaudible).
But the impact of these buttons is much deeper than this.
These buttons control output and export. If the light is dark, NOTHING on that track will be seen, heard, output or export.
I use these in a variety of ways:
- To see a clip below another clip.
- To keep source audio files in the Timeline, but only hear the mix.
- To quickly switch between English titles (on, say track 4) and Spanish titles (on, say, track 5)
These buttons give me the power to control exactly which tracks I export in every sequence.
Note: Whenever you change the visibllity of a track, you always lose your render files. (Yes, Final Cut will warn you.) This is because render files are associated with the sequence, not the clip, and since you are changing what is visible in the sequence, the render files need to change.
