Color safe warning?

PostThu Jun 04, 2015 4:15 am

Hello:
Isn't there a way to get a red flag from a illegal color (unsafe color) with sub views? I know you can hit shift V the make the window larger.
Cheers

The Saver can flag/adjust illegal colors.

SubViews? No, but you can do it with a ViewShader. Oh, or a view macro (I forget what they are called, but you can do a pair of gamut tools, transforming to and back from the target space, then do a difference or CT to generate the flag pixels, then merge that over the original image and wrap that up in a macro where you expose the colorspace you are interested in testing for).

Got it thanks! I usually fight this battle elsewhere in my workflow. Zebra LUT view. I tried the saver the saver method but I don't see any feedback before or during rendering.

The Zebra Viewshader shows colors less than 0 and greater than 1. It's not designed to flag colors that will be lost to a colorspace conversion or are considered illegal for broadcast (but that's not an issue much anymore, right?). You can modify it and make it do what you want, the shader is in the Fuses directory.
