How to duplicate a composition in after effects and make it independent from the original

[NESTOR_FEIJOO]

Hi, im trying to duplicate a composition in after effects and make it independent from the original but it seems to be imposible.. im working on CS5.

Can somebody help me PLEASE??

Thanks

I copied all the layers/rows of the original comp I wanted to duplicate, then selected (composition>new), and pasted the components into it. Then I dragged the new comp back into my timeline from the Project and this stopped linking the two comps together. Hope that helps!

@Ciara Tobin Tried that. Didn't work. I'll give the script mentioned above a shot.

I have the same problem - duplicating the composition in the project panel does not help if you have a composition with too many adjustments - cuts, keyframes, effects etc., that you have to add to the new composition.

This is a pefect solution for that!

No, it is not - as it is a paid plugin. AND you have to duplicate in the panel, which does not duplicate adjustments.

here is a script I created to do this - just select the comp you want to duplicate in your project panel and run this script file - if you don't know how to make a jsx from this just open TextEdit on a Mac (not sure what it is on Windows) and paste this > in the top bar click Format and select Make Plain Text > save it > go into your Finder and rename the file with .jsx at the end, and then you can run it in after effects enjoy!

// Duplicate selected comp and all nested comps
(function() {
    var proj = app.project;

    // Function to recursively duplicate a composition and all nested comps
    function duplicateComp(comp, compMap) {
        // If comp is already duplicated, return the duplicated one
        if (compMap[comp.id]) {
            return compMap[comp.id];
        }

        // Duplicate the main comp
        var duplicatedComp = comp.duplicate();
        duplicatedComp.name = comp.name + "_copy";

        // Add the duplicated comp to the map
        compMap[comp.id] = duplicatedComp;

        // Loop through all layers to find nested comps
        for (var i = 1; i <= duplicatedComp.numLayers; i++) {
            var layer = duplicatedComp.layer(i);

            if (layer.source && layer.source instanceof CompItem) {
                // Recursively duplicate the nested comp
                var nestedComp = layer.source;
                var duplicatedNestedComp = duplicateComp(nestedComp, compMap);

                // Replace the original nested comp with the duplicated one
                layer.replaceSource(duplicatedNestedComp, false);
            }
        }

        return duplicatedComp;
    }

    app.beginUndoGroup("Duplicate Comp with Nested Comps");

    if (proj.selection.length > 0 && proj.selection[0] instanceof CompItem) {
        var selectedComp = proj.selection[0];

        // Map to store duplicated comps to avoid duplicating the same comp multiple times
        var compMap = {};
        duplicateComp(selectedComp, compMap);

        alert("Duplicate process completed!");
    } else {
        alert("Please select a composition in the Project panel.");
    }

    app.endUndoGroup();
})();
