Color Slice Tool?

In the book, Digital Compositing for Film and Video Production, Steve Wright makes extensive use of a "slice tool", in which you draw a line across footage and you get a graph of the pixel brightness for each color along that line. I know the Info panel displays this for the current cursor position. And the Lumutri scopes can kinda of sorta give me the desired info for a masked-off horizontal area, but not really for a vertical area.

I wondering if there is a way to get an RGB brightness graph along a line, regardless of orientation. I suspect I am missing an obvious solution. Thanks for any help.

    Our Test Gear product includes a Slice Tool.

    Download and install as demo to see if it works like you want. You define begin and end points and you can see the slice at any angle, any length.

      Thank you, Bob. I'll give it a try. Does it require QuickTime on Windows? The Color Finesse plug-in that comes with AE won't run on my system since I uninstalled QT for security purposes.

      Bob: I downloaded the trial and it is exactly what I wanted. SOLD!

      I'm interested in the other scopes that come with Test Gear. is there anything you can tell me about why they are preferable to the Lumetri ones?

      Many thanks!

      Does it matter, in a negative manner, if your layer was rotated 90 degrees, to get what you want?

      Thanks, that works, but I'm hoping for a less cumbersome approach.

      A single change to Transform>Rotation is cumbersome? You can't be serious.

      I guess it depends on what you intend to do with the data. The sampleImage Expression method is able to grab RGB values of a single pixel; defined in RGBA values - then use color conversion into HSLA to obtain the Lightness value. But that's cumbersome. ;-)
