What do these paths look like (your link doesn’t seem to work)?

Like this:


if (marker.numKeys > 1){
t1 = marker.key(1).time;
t2 = marker.key(2).time
linear(time,t1,t2,t2,0).toFixed(0);
}else
0

Like this, I guess:


if (marker.numKeys > 1){
t1 = marker.key(1).time;
t2 = marker.key(2).time
linear(time,t1,t2,t2,0).toFixed(1);
}else
0

Ah, OK. I thought you wanted to control the duration with the duration of a sjingle, split marker. If you’re using two markers, try this instead:


if (marker.numKeys > 1){
t1 = marker.key(1).time;
t2 = marker.key(2).time
linear(time,t1,t2,t1,0).toFixed(1);
}else
0

You would apply the expression to the Source Text property of a text layer, and the expression expects a split marker on that layer.

Like this maybe:


tStep = framesToTime(12);
tPause = framesToTime(10);
jumpX = 10;
t = time - inPoint;
nSteps = Math.floor(t/(tStep+tPause));
phase = t-((tStep+tPause)*nSteps);
e = ease(phase,0,tStep,0,jumpX);
value + [nSteps*jumpX + e,0]

Maybe something like this:


if (marker.numKeys > 0){
m = marker.key(1);
linear(time,m.time,m.time+m.duration,m.duration,0).toFixed(1);
}else
0


Dan

[Dan Ebberts]

That’s a little vague, but see if this does what you want:


m = thisComp.layer("0").marker;
if (m.numKeys > 1 && numKeys > 0){
t = linear(time,m.key(1).time,m.key(2).time,key(1).time,key(numKeys).time);
valueAtTime(t);
}else
value

I’m not sure what you’re asking. Are you asking how to rename a layer using a script? It might be something like this:

app.project.activeItem.layer(1). name = “BG”;

Or are you asking something else entirely?

Dan

Something like this maybe:


period = 3;
t = (time - inPoint)%period;
if (t < period/2)
linear(t,0,period/2,0,90)
else
linear(t,period/2,period,90,0)
