How to use the script

Always check code before running it on your computer. Even basic scripts like this one. If you’re not a developer, ask an LLM like ChatGPT, Claude, or Gemini to verify it for you.

Option 1: Install to your AE Folder

Download and install the below .jsx file in your After Effects Script folder. You can then run it using the scripts menu, or by using a launcher like Quick Menu 3.

Option 2: Adapt the script yourself

Alternatively copy the code below and develop your own version. If you’re not a developer you can do this easily with an LLM like ChatGPT.

4K Comp 👇

// Create a new 4K composition (3840x2160)
// adapt the elements below for your personal specs

var compWidth = 3840;
var compHeight = 2160;
var compDuration = 300; // Duration in seconds (300 = 5 minutes)
var compFrameRate = 30; // Frame rate

// Create the composition
var newComp = app.project.items.addComp("4K_Comp", compWidth, compHeight, 1, compDuration, compFrameRate);

// Set the background color (optional)
newComp.bgColor = [0, 0, 0]; // Black background

// Prompt the user for the composition name
var compName = prompt("Enter the name for the new composition:", "4K_Comp");

// Rename the composition with the user-provided name
if (compName !== null && compName !== "") {
    newComp.name = compName;
}

// Open the composition in the viewer
newComp.openInViewer();

Custom Comp 👇

// Create a new window
var dialog = new Window("dialog", "New Composition Settings");

// Add input fields and labels
dialog.add("statictext", undefined, "Composition Name:");
var compNameInput = dialog.add("edittext", undefined, "4K_Comp");
compNameInput.characters = 20;
compNameInput.active = true; // Set focus to the first input field

dialog.add("statictext", undefined, "Width:");
var compWidthInput = dialog.add("edittext", undefined, "3840");
compWidthInput.characters = 10;

dialog.add("statictext", undefined, "Height:");
var compHeightInput = dialog.add("edittext", undefined, "2160");
compHeightInput.characters = 10;

dialog.add("statictext", undefined, "Frame Rate:");
var compFrameRateInput = dialog.add("edittext", undefined, "30");
compFrameRateInput.characters = 10;

dialog.add("statictext", undefined, "Scale Factor:");
var scaleFactorInput = dialog.add("edittext", undefined, "1");
scaleFactorInput.characters = 10;

// Add OK and Cancel buttons
var okButton = dialog.add("button", undefined, "OK", {name: "ok"});
var cancelButton = dialog.add("button", undefined, "Cancel", {name: "cancel"});

// Show the dialog and get the result
if (dialog.show() == 1) {
    var compName = compNameInput.text;
    var compWidth = parseInt(compWidthInput.text, 10);
    var compHeight = parseInt(compHeightInput.text, 10);
    var compFrameRate = parseInt(compFrameRateInput.text, 10);
    var scaleFactor = parseFloat(scaleFactorInput.text);

    if (compName !== "" && !isNaN(compWidth) && !isNaN(compHeight) && !isNaN(compFrameRate) && !isNaN(scaleFactor)) {
        if (scaleFactor > 1) {
            compWidth *= scaleFactor;
            compHeight *= scaleFactor;
        }

        var compDuration = 300; // Duration in seconds (5 minutes)

        // Create the composition
        var newComp = app.project.items.addComp(compName, compWidth, compHeight, 1, compDuration, compFrameRate);

        // Set the background color (optional)
        newComp.bgColor = [0, 0, 0]; // Black background

        // Open the composition in the viewer
        newComp.openInViewer();
    } else {
        alert("Invalid input. Please enter valid values for all fields.");
    }
