能否通过CMD命令行调用Adobe After Effects脚本生成指定视频？求示例

Absolutely! While After Effects doesn’t natively accept raw parameters like red HelloWorld directly in the command line, you can achieve this by pairing a JSX script (After Effects’ native scripting language) with a CMD command that passes your desired parameters to the script. Here’s a complete, working example to make it happen:

Step 1: Create the JSX Script #

First, make a new text file named generateVideo.jsx and paste the following code. This script reads your command-line arguments, builds a composition with the specified background color and text, then renders the final video:

// Check if required arguments are provided
if ($.argv.length < 3) {
    alert("Missing arguments! Usage: afterfx.exe -r generateVideo.jsx [color] [text]");
    app.quit();
}

// Pull arguments from command line
const bgColorName = $.argv[1].toLowerCase();
const displayText = $.argv[2];

// Map common color names to RGB values (add more as needed)
const colorMap = {
    red: [1, 0, 0],
    blue: [0, 0, 1],
    green: [0, 1, 0],
    white: [1, 1, 1],
    black: [0, 0, 0]
};

// Default to red if color name is unrecognized
const bgColor = colorMap[bgColorName] || colorMap.red;

// Create a new AE project
app.newProject();

// Set up a 1920x1080 composition (10 seconds, 30fps)
const comp = app.project.items.addComp(
    "HelloWorldComp",
    1920,
    1080,
    1,
    10,
    30
);

// Add solid background layer with chosen color
const bgSolid = comp.layers.addSolid(
    new Color(bgColor[0], bgColor[1], bgColor[2]),
    "Background",
    comp.width,
    comp.height,
    1
);

// Add and style the text layer
const textLayer = comp.layers.addText(displayText);
// Center text on screen
textLayer.property("Position").setValue([comp.width/2, comp.height/2]);
// Customize text appearance (adjust font/size as you like)
const textProp = textLayer.property("Source Text").value;
textProp.fontSize = 72;
textProp.fillColor = new Color(1,1,1); // White text
textLayer.property("Source Text").setValue(textProp);

// Configure render queue for MP4 output
const renderQueue = app.project.renderQueue.items.add(comp);
const outputModule = renderQueue.outputModules[1];
outputModule.applyTemplate("H.264");
// Set your desired output path (create this folder first!)
outputModule.file = new File("C:\\AE_Renders\\HelloWorldOutput.mp4");

// Start rendering
renderQueue.render();

// Uncomment below to auto-close AE after rendering
// app.quit();

Step 2: Run the CMD Command #

Open Command Prompt and execute this command (adjust paths to match your system setup):

"C:\Program Files\Adobe\Adobe After Effects 2024\Support Files\afterfx.exe" -r "C:\Path\To\Your\generateVideo.jsx" red "Hello World"

Command Breakdown: #

• "C:\...\afterfx.exe": Full path to your After Effects executable (skip quotes if the path has no spaces).
• -r: Tells After Effects to run a script instead of opening the UI normally.
• "C:\Path\To\Your\generateVideo.jsx": Full path to the JSX script you created.
• red: The background color (matches the names in the script’s colorMap).
• "Hello World": The text to display (wrap in quotes if it includes spaces).

Key Notes: #

• Render Folder: Make sure the output folder (like C:\AE_Renders) exists before running the command—AE won’t create it automatically.
• Color Expansion: Add more entries to the colorMap object in the script to support additional colors (e.g., purple: [0.5, 0, 0.5]).
• AE Version: Update the path to afterfx.exe to match your installed version (e.g., 2023, 2022).
• Auto-Quit: Uncomment app.quit(); in the script if you want After Effects to close once rendering finishes.

This setup will generate a 10-second MP4 video with a red background and centered white "Hello World" text—all via the command line, just as you requested!
