运行 shell 渲染完成时的命令（After Effects）

Question

在 Adobe After effects 中完成渲染后，有没有办法以编程方式运行 shell 命令？

Answer 1

试试这个代码。您唯一需要调查的是 (rq_item.status === RQItemStatus.DONE) 被调用两次的原因。

// Create a comp with a solid
var comp = app.project.items.addComp('test', 100, 100, 1, 1, 12);
comp.layers.addSolid([0.5, 0.5, 0.5], 'solid', 100, 100, 1, 1);
// Add the comp to the render queue
var rq_item = app.project.renderQueue.items.add(comp);
rq_item.outputModule(1).file = File('~/Desktop/out.mov');
rq_item.render = true;
// Set a function which will be called every frame when the comp will be rendering
// A boolean to be sure that the function called at the end is called once
var called = false;
rq_item.onStatusChanged = function() {
  while (rq_item.status === RQItemStatus.RENDERING) {
    // Is rendering...
    $.writeln('Rendering');

  }

  // When the render is finished
  if (!called && rq_item.status === RQItemStatus.DONE) {
    called = true;
    $.writeln('Done rendering');
    // test for Mac or Win
    var res = null;
    if($.os.charAt (0) === 'M'){
      res = system.callSystem('echo "Hello Mac World"');
    }else{
      res = system.callSystem('cmd.exe /c echo "Hello Win World"');
    }
    $.writeln(res);
  }

};
// Launch the render
app.project.renderQueue.render();

// If something goes wrong
app.onError = function(err) {
  $.writeln('ERROR ' + err);
};

Answer 2

从 After Effects 执行命令行

您可以使用 sysmte.callSystem(cmdLineToExecute) 函数执行命令行。请查看 After Effects Scripting Guide 页 180 部分 System callSystem() 方法.

这是一个 echo 命令的例子：（callSystemreturn 命令行 return 的）：

var commandOutput = system.callSystem("cmd.exe /c echo hi ");
alert(commandOutput);

这将输出

hi

/c后面是cmd中要执行的命令

脚本指南中获取系统时间的更复杂示例：

var timeStr = system.callSystem("cmd.exe /c \"time /t\"");
alert("Current time is " + timeStr);

这将输出

Curent time is 11:28

从 After Effects 打开命令行

现在，如果您想在另一个 window 中打开命令行，则必须像在命令行中一样设置 cmdLineToExecute。

在 windows 上，如果你想在另一个 window 上打开命令行，你必须这样做：

start cmd.exe

所以如果你想从 After

开始

system.callSystem("cmd.exe /c start cmd.exe ");

这是与@fabiantheblind 的回答的混合。

// Create a comp with a solid
var comp = app.project.items.addComp('test', 100, 100, 1, 1, 12);
comp.layers.addSolid([0.5, 0.5, 0.5], 'solid', 100, 100, 1, 1);
// Add the comp to the render queue
var rq_item = app.project.renderQueue.items.add(comp);
rq_item.outputModule(1).file = File('~/Desktop/out.mov');
rq_item.render = true;
// Set a function which will be called every frame when the comp will be rendering
// A boolean to be sure that the function called at the end is called once
var called = false;
rq_item.onStatusChanged = function() {
  while (rq_item.status === RQItemStatus.RENDERING) {
    // Is rendering...
    $.writeln('Rendering');

  }

  // When the render is finished
  if (!called && rq_item.status === RQItemStatus.DONE) {
    called = true;
    system.callSystem("cmd.exe /c start cmd.exe ");
  }

};
// Launch the render
app.project.renderQueue.render();

// If something goes wrong
app.onError = function(err) {
  $.writeln('ERROR ' + err);
};
