Random Color but changing every 5 frames
Hi.. I never use expressions but I need to, HELP! hehe
I’m trying to make random colors. Here is how far I’ve gotten I figured out the expression to change the color I”m using the Color Balance (HLS) effect and on the Hue property I used the expression “Random (1,360)” The problem is that changes the color every frame, I need to slow that down and only have it change after 5 frames then the next 5 and so on.
Thanks!

The easiest way to do this is to limit the number of times the expression evaluates with the
posterizeTime(fps);function, like so:
x = 5;
f = thisComp.frameDuration * x; //The duration in seconds of 'x' frames in this compositionposterizeTime(1 / f); //Evaluate everything after this line every x frames
random(1, 360);

Question for Darby:
How would one go about making the same expression, but having the rate of the changing colors also be random (as opposed to 5)?
Thanks!!

Clarisse, you can set a variable equal to random() and if you need to increase the amount of random you can pass in a hard value of 100 or even 1000 depending on the amount you need for your comp.
I use random(time*100)
Hope this helps.
