Final Cut Pro – Control Your Chroma Levels
Excess chroma levels are dangerous. Here’s how to see if yours are OK.
If you aren’t careful, you can easily create colors on your computer that can’t be displayed in video. Remember, computers use an RGB color space, while digital video uses the more restrictive YCrCb (Apple calls this YUV, but YUV is only an analog video format).
To see if your chroma levels are too hot, select either the Canvas or the Viewer, and choose View > Range Check > Excess Chroma.
If you see a yellow warning triangle, your levels are too hot. A green check-mark means they are OK.
Note: If you type Control+Z, this will warn you if your luminance levels are OK, but does NOT indicate excessive chroma levels.
