Tip #1452: The Mysterious Red Box
The red “slider” simplifies navigating a zoomed-in Viewer image.
You’ve seen it from time to time, the mysterious red box in Final Cut’s Viewer. What the heck is it?
The red slider appears whenever you are zoomed into an image more than the Viewer can display.
Drag the red box itself to navigate around the image.
To display the red box, type Cmd + [plus] to zoom into the Viewer.
To make the red box disappear, type Shift + Z (or choose Fit from the View menu).
