Interact with Auto-Trace prompt pop up?

Hi @sen93, welcome to the forum!

Yes, I’ve encountered a similar question from another user, and the solution might work for you as well. The user needed to simulate a key press on the keyboard—in his case, the letter “p.”

Simulating a key press can also solve your problem. By triggering the “Enter” key press right after the Auto-trace window appears, you can automate the entire process without needing to move your mouse.

Here’s the older post that might help: Adding existing AE keyboard shortcuts to actions

This post details methods to trigger a key press natively on both Mac and Windows, using AppleScript on Mac and PowerShell on Windows.


In your case, you will need to run a Windows batch script before executing the menu command.

Why should you run the Windows script to trigger the “Enter” key before opening the Auto-trace window?

If you run the menu command first and then the script to trigger the key press, the script won’t execute until you manually close the Auto-trace window. This is because the automation stops and waits for the menu command to resolve before continuing.

The solution is to run the Windows batch script with a small delay—set it to 1 second before it triggers the “Enter” key press. Then, execute the menu command. This delay allows the Auto-trace window to open, and the script will automatically press “Enter” after 1 second, completing the automation smoothly.



Creating the PowerShell script -

You need to create a batch file (.bat file that contains a PowerShell code that when run will simulate a key press) -

  1. open the notepad software.
  2. paste this code -
if "%1" == "" start "" /min "%~f0" IS_MINIMIZED && exit
powershell -Command "Start-Sleep -Seconds 1; Add-Type -AssemblyName System.Windows.Forms; [System.Windows.Forms.SendKeys]::SendWait('{ENTER}')"
exit

(the first line tells this cmd window to open in minimized mode without taking the focus from the After Effects window, second line start a time delay of 1 second and runs powershell code to simulate the key press, third line tells it to exit the cmd window)

  1. save this script file with .bat file extension, for example “keyboard shortcut 1.bat”.

I left the creation process for you as it is more safe, downloading a malicious shell script can be very dangerous.



Instructions on how to use this bat file -

create an automation that will run this script from automation toolkit -

  1. create a file variable and select the script file you just created (click the folder icon and select the file).
  2. add an action and select the file variable name, and then select open.

    download -
    keyboard shortcut.json (1.9 KB)

the automation is ready!

finally you just have to disable this warning message in the preferences (scripting & expressions) -




This Automation only execute the (.bat) script that waits 1 second and then press enter so you will not be able to see its effect without adding the menu command after these 2 lines



Here is the automation with the Auto-Trace menu command -

(remember that you need to select the (.bat) script file that you created earlier)
