Introduction

<p>ExtendScript, the established scripting language in AE, poses certain limitations particularly around sophisticated tasks such as pixel or audio data manipulation, as well as certain automation tasks.<p> <p>Its capabilities are somewhat confined, often demanding a transition to the more complex C++ SDK for advanced functionalities, or packaging 3rd party node modules or python venvs to achieve the functionality you truly want.<p>

• PyShiftAE is an experimental, Open Source library designed to transcend the boundaries of the built-in ExtendScript library in Adobe After Effects (AE), heralding a new era of scripting possibilities in AE.

• By offering a Python library as an alternative to ExtendScript, PyShiftAE not only enriches the existing feature set but simplifies and amplifies the scripting experience. PyShiftAE is NOT a wrapper around extendscript. Instead, it is a python library written around the c++ SDK.

• PyShiftAE not only allows scripting of AE through python, but integration of most (if not all) external python libraries, provided you have the installed.

As ways to script shapes/masks/text et alia are implemented, this will open doors to python data-driven animation within AE, utilization of various ML and AI libraries, and much, much more.

Problem Statement:

ExtendScript, the established scripting language in AE, poses certain limitations particularly around sophisticated tasks such as pixel or audio data manipulation. Its capabilities are somewhat confined, often demanding a transition to the more complex C++ SDK for advanced functionalities.

Why PyShiftAE?:

• Ease of Use: Python, being a more intuitive and widely adopted language compared to ExtendScript, lowers the entry barrier for scriptwriters.
• Extended Functionality: PyShiftAE is not a mere wrapper around ExtendScript; it's a full-fledged library offering novel functionalities and a simplified approach to existing ones.
• Community Empowerment: With PyShiftAE, a broader spectrum of developers including CEP developers and those proficient in Python can effortlessly script in AE, thus democratizing advanced scripting capabilities.
• Innovation Unleashed: Direct integration with APIs, machine learning libraries, and more becomes a reality with PyShiftAE, paving the way for innovative scripts and extensions.

Impact:

The ripple effect of PyShiftAE in the AE community could be profound. Scriptwriters could venture into more advanced coding territories, and CEP extension authors could craft hybrid extensions blending SDK features via PyShiftAE, thereby catalyzing a wave of innovative solutions in the AE ecosystem.

Requirements:

---

To Use PyShiftAE, you must have the following core dependencies installed;

• Windows 10/11, x64 build
• Python 3.1X
• After Effects 2023 or above.

Installation

1. Check Your Python Version

1. Make sure you have Python 3.1x installed (e.g., Python 3.11 or 3.12).
   • To verify, open a terminal and run:

     python --version
     

     or

     python3 --version
     

   • The output should show a Python version in the 3.1x range.

2. Obtain the Matching Wheel

1. Download the latest .whl file for your Python version (e.g., cp311 for Python 3.11).
2. Keep in mind that PyShiftAE will use whichever Python interpreter is first in your system PATH.

3. Install the Wheel

1. Open a terminal in the same folder where you saved the .whl.
2. Install with pip:

   pip install pyshiftae-0.1.1-cp311-cp311-win_amd64.whl

4. Install the Plugin

1. Open a new python terminal.
2. Run the command:

   psc-install

3. Paste the proper Effects Directory into the input. Voila!
4. Restart AE.
