Where do I find the luma range clip indicator that I have in Final Cut?

You can add a new adjustment layer at the top of your composition, with the Levels effect set to the following:

  • Input Black: 254
  • Input White: 255

Levels effect

This will have the result of causing any luma values that were below 254 to become black, while anything above it becomes white. Here is an example of it over a fractal noise pattern:

I don’t think there’s a way to get zebras on your output, but the Lumetri Scopes will give you a video signal that will show you whether your luma is too high.


  • Unfortunately, they're not helping. I need to know exactly where in the image the luma is clipping. I have demonstration-videos shot on white background and I need to make that background be absolute white (255,255,255). – Birowsky May 5 '20 at 9:37
  • I would adjust the levels on the shot until I can see that the Luma levels are at absolute white on the scopes. – tomh May 5 '20 at 10:00
