color match problem – script or plugin available?
The color picker works great for stills in order to match a BG color ie. gradient to a specific area of footage.
1. What if the color/brightness, of the footage is changing constantly? Is there a way to to collect color information from a specific area of the footage (color pick) on every frame and automatically apply these changing color values to a fill or gradient?
2. Furthermore the footage is moving. The color picker would need to be linked to a tracker null, so the samples will always be picked from the same area.
Does anyone know of a script or plugin to get this done? -

You could us the sampleimage expression for this.

Thanks Chris, I’ll try that as soon as I’m in front of the pc again. Since I can’t write any code I hope I’ll be able to get it to run.
Thanks to Matthias from Mammoworld, I got this link, Dan Ebberts explained it here:
https://www.motionscript.com/design-guide/sample-image.html“transform.position” – how do I link that to the position of the null?

You can simple pick whip the position value of the null as the position value for where to sample. Or set that as a variable and use the variable. Using Dans example.
target = thisComp.layer("background");null = thisComp.layer(“yournulllayer”).transform.position; target.sampleImage(null, [width, height]/2, true, time) -
Thanks Chris,
I’ll try that tomorrow morning. Glad you came back to my question! -
It sounds like the color stabilizer effect could fix what you’re after.
