After Effects Expressions: Control and key your preComp effects from the Master Comp

A nifty little expression I use to link effects in preComps to a null object I name "Control" in the Master Layer. This allows me to animate my effects from my Master Comp instead of hopping back and forth between my preComps and Master Comp to check the timing. Here's the expression from the video with comments about each line after the "//": t = comp("Master_Comp").layer("Comp 2").inPoint //this gets the time the preComp layer starts in the Master Comp and sets it to the variable "t" comp("Master_Comp").layer("Control").effect("Slider Control")("Slider").valueAtTime(t + time) //this adds the time in the preComp and the Master Comp so the keys are timed correctly between comps Now remember, you can put multiple Expression Control effects on the Control layer so all your effects from different preComps can live in one spot on your Master Comp.
