Script cannot set effect property value
I have a layer that has “Dust & Scratches” effect applied.
The layer has several Time Remap keyframes and I am applying this code on that Time Remap property like this:effect("Dust & Scratches")("Threshold") = 60;But I got error saying “Cannot apply value” – does anyone know why?

You should apply an expression to the property you want to effect, not to time-remapping.
There is no way to set the value of property B from within an expression on property A.
An expression should always yield a value that is used instead of the current keyframed value of the property it is applied to.if you want to know the value of the Threshold you would use
a = effect("Dust & Scratches")("Threshold");But you can only read that value, not set it.So, if you want Threshold to always be 60 regardless of it’s keyframes or time, simply apply this expression to it:
60;
