Scale selected comps, overwrite selected comps
Found the code I need here: https://www.aenhancers.com/viewtopic.php?t=701
But I just want it to overwrite the selected comps, not create new ones called “resize”. I figured I could just add a section that says mySelection[i].remove(); but this deletes the layers within the new comp and I can’t figure out why. Code is below:
var percent = prompt("Resize factor (percentage):","50");
var mySelection = app.project.selection;
app.beginUndoGroup("scaleSelectedComps.jsx");
for (var i = 0; i < mySelection.length; i++)
{
if (mySelection[i] instanceof CompItem)
{
var compName = mySelection[i].name;
var W = Math.round(mySelection[i].width * percent/100);
var H = Math.round(mySelection[i].height* percent/100);
var pixAsp = mySelection[i].pixelAspect;
var Dur = mySelection[i].duration;
var frRate = mySelection[i].frameRate;
var resizedComp = app.project.items.addComp(compName,W,H,pixAsp,Dur,frRate);
var myLayer = resizedComp.layers.add(mySelection[i]);
myLayer.scale.setValue([percent,percent]);
mySelection[i].remove(); //this should just remove the current selected comp, but instead deletes the layers within that comp, and the new comp created from var ResizedComp is created empty.
}
}
app.endUndoGroup();

Your script creates a resized comp, then adds the original comp as a layer and scales it. So when you then delete the original comp, you’re deleting the source for the only layer in your new comp.

Ah, you’re right. I didn’t take a very close look at it from the AEenhancer’s forum.

Ok, I’ve gone in and rewritten it a little bit, but I’m getting an error at line 12: “Undefined is not an object”. Not sure if I’m missing the correct syntax for scaling or what.
var percent = prompt("Resize factor (percentage):","50");
var mySelection = app.project.selection;
app.beginUndoGroup("scaleSelectedComps.jsx");
for (var i = 0; i < mySelection.length; i++){
if (mySelection[i] instanceof CompItem){mySelection[i].width = Math.round(mySelection[i].width * percent/100);
mySelection[i].height = Math.round(mySelection[i].height* percent/100);
curComp = mySelection[i];
for (var b = 0; b <= curComp.numLayers; b++){
var curLayer = curComp.layer[b];
curLayer.scale.setValue([percent,percent]); //this is where the error is
}
}
}
app.endUndoGroup(); -
I’d change your layer loop to look like this:
for (var b = 1; b <= curComp.numLayers; b++){
var curLayer = curComp.layer(b);
curLayer.scale.setValue([percent,percent]);
}

Ah, super helpful. Thanks Dan.
For anyone interested, here is my script. It will take all selected comps, and scale them by the factor you set, and re-center the layers in them. Simple, but strangely I couldn’t find anyone else who made something like this that worked for more than one selected comp.
Copy and paste the below into a new text document, with a .jsx extension and throw into your AE scripts folder:
//prompt percentage and set selections
var percent = prompt("Resize factor (percentage):","200");
var mySelection = app.project.selection;
app.beginUndoGroup("scaleSelectedComps.jsx");//for every comp selected, set resolution based on percent value from user
for (var i = 0; i < mySelection.length; i++){
if (mySelection[i] instanceof CompItem){
mySelection[i].width = Math.round(mySelection[i].width * percent/100);
mySelection[i].height = Math.round(mySelection[i].height* percent/100);
curComp = mySelection[i];//for each layer within each selected comp, scale and re-center based on percent value from user
for (var b = 1; b <= curComp.numLayers; b++){
var curLayer = curComp.layer(b);
curLayer.scale.setValue([percent,percent]);
curLayer.position.setValue([curComp.width/2,curComp.height/2]);
}
}
}
app.endUndoGroup();
//done! :)
