I need a script that reposition the single layer in a precomp -1 in the Y and then render the main comp (which is one frame long) with a name of the the absolute vaule of the Y position of the layer in the precomp - the script needs to continue until you reached a variable (which can be set in the script and would usually be the size of the element in the precomp)
Basically I'm creating streak photography and in order to create the animation you need to reposition the source and then render a single frame and repeat until you reach the size of the source - streak photography as I understand it turns time into space (I was able to do this in ae using expressions) and space into time (this is what I need the script for)
thanks,
