Not new (it’s the JavaScript conditional operator), but I like it because you can use it on a single line with minimal punctuation.

[Dan Ebberts]

Yes, sorry–that should have been:

L = thisComp.layer(layers[i]);

[Dan Ebberts]

I think the last line would just be:

[size,size]

[Dan Ebberts]

I think I’d do it with a loop. This won’t be exactly right (I haven’t tested it at all), but maybe it’ll get you headed in the right direction:

gap = 36;
layers = ["TEXT1","TEXT2","TEXT3"];
times =  [    2,          2,         7  ];
maxX = 0;
for (i = 0; i < layers.length; i++){
  L = thisComp.layer(i);
  rect = L.sourceRectAtTime();
  x = L.toComp([rect.left+rect.width,0],times[i])[0];
  xclamp=clamp(x,545.70,2000);
  maxX = Math.max(maxX,xclamp);
}
maxX+gap

I’d suggest trying it this way:

f=thisComp.layer("cam ctrl").transform.position;
k1=f.key(2).value[2];
k2=f.key(3).value[2];
time < f.key(2).time ? 0 : linear(f[2],k1,k2,0,58);

[Dan Ebberts]

Ah. I think you might be using the Legacy ExtendScript expression engine. If you can’t switch to the JavaScript engine for some reason, try changing your fist line to this:

c = thisComp.layer("BackgroundControls").effect("CropSelection")("Menu").value;

[Dan Ebberts]

It works for me without the toString(), but where have you applied this expression?

[Dan Ebberts]

Hmm… It works for me. The only way I can make it fail with that message is to do this:

f=thisComp.layer("50MM").cameraOption;

instaed of this:

f=thisComp.layer("50MM").cameraOption.zoom;

Maybe you could post a screen shot.

[Dan Ebberts]

I guess it depends on what you’re going to do with the result. This gets you pretty close:

t1 = framesToTime(80);
t2 = framesToTime(90);
linear(time,t1,t2,1,2)

[Dan Ebberts]

Try this:

f=thisComp.layer("50MM").cameraOption.zoom;
k1=f.key(4).value;
k2=f.key(5).value;
time < f.key(4).time ? 0 : linear(f,k1,k2,100,0);
