control time remap by position of another layer
hi
i want to control a layer’s time remap property using the position of a null in another comp.
its for playing animation controled by a graph (the null is moving along the graph with keyframes).
i need to be able to play the animation back & forth in changed speeds, acording to the null’s position.
i tryed with “linear” expression but i get errors, or the timeremap property stay on a fixed value that is one frame after the animation ends.here is what i did:
comp GRAPH:
a null has keyframes of position follows along the graph.
comp MAIN:
animation layer has on the timeremap:
open=0;
close=152; //frame#, when i tried with seconds i got “; expected error //
linear(GRAPH null position,302,448,close,open)the resault was timeremap valu stuck on 300. the last frame is 299, so the layer i invisable at 300.
help?
thankes,

Time remap does expect values in seconds, not frames. Assuming you are using movement of the null along the x axis to control the time remap, I think it will look something like this (not tested):
open=0;
close=152*thisComp.frameDuration;
x = comp(“GRAPH”).layer(“Null 1”).transform.position[0];
linear(x,302,448,close,open)Dan
