Batch Sequence Layers on Multiple Compositions from Project Panel
Hello all,
I’m hoping you can help me with this question. I am looking for a solution of how to sequence layers within multiple compositions at once. Perhaps via a script?
Basically I want to be able to select many compositions in the project panel at once, hit a button, and they all automatically run the same process that Keyframe Assistant does to sequence their contained layers with no overlap.
Does anyone have knowledge of how this could be achieved?

It seems like it should be pretty straightforward. Something like this maybe:
var mySelection = app.project.selection;
var myComp, delta;
for (var i = 0; i < mySelection.length; i++){
myComp = mySelection[i];
if (! (myComp instanceof CompItem)) continue;
for (var j = myComp.numLayers; j >1; j--){
delta = myComp.layer(j).outPoint - myComp.layer(j-1).inPoint;
myComp.layer(j-1).startTime +=delta;
}
} -
Fantastic Dan, thank you so much this is great! Just have one further question…
It works like a charm as long as there are no locked layers in the compositions, if there are locked layers it gives an error after the first composition and doesn’t affect the following compositions selected in the project panel. Is there any way around this, for the script to ignore errors and keep running?
-
What should it do when it encounters a locked layer?

Ideally, the script would ignore the locked layers. I am using this script to sequence certain (unlocked) layers in many compositions, but I want other layers (locked) within these same compositions to be unaffected by the layer sequencing process.
Thanks for your help with this!

Try this:
var mySelection = app.project.selection;
var myComp, delta;
for (var i = 0; i < mySelection.length; i++){
myComp = mySelection[i];
if (! (myComp instanceof CompItem)) continue;
for (var j = myComp.numLayers; j >1; j--){
if (myComp.layer(j).locked) continue;
for (var k = j -1; k > 0; k--){
if (myComp.layer(k).locked) continue;
delta = myComp.layer(j).outPoint - myComp.layer(k).inPoint;
myComp.layer(k).startTime +=delta;
}
}

This is perfect Dan! Thank you so much for your help. This will save me a ton of time.

Thanks for this solve, Dan!

Actually, that last one isn’t quite right. This should be better:
var mySelection = app.project.selection;
var myComp, delta;
for (var i = 0; i < mySelection.length; i++){
myComp = mySelection[i];
if (! (myComp instanceof CompItem)) continue;
for (var j = myComp.numLayers; j >1; j--){
if (myComp.layer(j).locked) continue;
for (var k = j -1; k > 0; k--){
if (myComp.layer(k).locked) continue;
delta = myComp.layer(j).outPoint - myComp.layer(k).inPoint;
myComp.layer(k).startTime +=delta;
break;
}
}

I’ll swap this one in, thank you again Dan!
