Animating wiggle frequency that way can give you unpredictable results. This may help:

I can’t think of a way you could get that error message. It works for me (although it could use some error checking to make sure a comp is actually selected). Did you run it the way I posted it, or did you make it part of something else?

[Dan Ebberts]

So you want the marker if the layer has a parent and is selected, is that correct? This should work:

var comp = app.project.activeItem;
var mySelected = comp.selectedLayers;
for (i = 0; i < mySelected.length; i++) {
	if (mySelected[i].parent != null) {
		var myMarker = new MarkerValue(mySelected[i].parent.name);
		mySelected[i].property("Marker").setValueAtTime(2, myMarker);
	}
}

Another possibility would be to use sourceRectAtTime() and toComp() to establish the corners:

L = thisComp.layer("square");
r = L.sourceRectAtTime(time,false);
ul = L.toComp([r.left,r.top]);
ur = L.toComp([r.left+r.width,r.top]);
ll = L.toComp([r.left,r.top+r.height]);
lr = L.toComp([r.left+r.width,r.top+r.height]);
xMin = Math.min(ul[0],ur[0],ll[0],lr[0]);
xMax = Math.max(ul[0],ur[0],ll[0],lr[0]);

>It’d be nice to be able to set something like thisLayer.source(footage(“blahblah.png”))

Agreed, it would be nice, but there’s nothing like that, unfortunately.

I think the closest you could come would be to include multiple footage layers and use opacity expressions to turn on only the one specified in the CSV.

<div>This should work:</div>

L = thisComp.layer("Layer 1");
time >= L.inPoint && time < L.outPoint ? 100 : 0

or, you could do it this way:

L = thisComp.layer("Layer 1");
L.active ? 100 : 0

I guess you wouldn’t really need the keyframes if they aren’t providing timing or value info, so this should work:

x1 = thisComp.layer("Camera Settings").effect("Camera In Animation X")(1);
x2 = thisComp.layer("Camera Settings").effect("Camera Out Animation X")(1);
t1 = thisComp.layer("Camera Settings").effect("Camera In Animation Time")(1);
t2 = thisComp.layer("Camera Settings").effect("Camera Out Animation Time")(1);
ease(time, t1, t2, x1, x2);

You probably just need to swap out the curly quotes for straight quotes:

L = thisComp.layer("Shape Layer 1");
path = L.content("Shape 1").content("Path 1").path;
pct = L.content("Shape 1").content("Trim Paths 1").end;
L.toWorld(path.pointOnPath(pct/100,time))

Like this maybe:

L = comp("Language").layer("Language");
cb1 = L.effect("EN")("Checkbox").value;
cb2 = L.effect("DE")("Checkbox").value;
cb3 = L.effect("ES")("Checkbox").value;
cb1 || cb2 || cb3 ? 100 : 0
