Convert light to keyframe?

You could use sampleImage() in an expression.

See Dan Ebberts’s classic Obscuration Using sampleImage() example [link] for some inspiration.

You can achieve this using the sampleimage expression. I’m no expressions expert but there are a few on this site. Just do a search for sampleimage and you’ll hopefully find something useful.

It basically returns the RGB values of any point you specify. You can then link whatever value you like (position, rotation, amount of blur, brightness of lens flare – whatever) to this value.

Hope that helps (a bit!)
