Description:
------------
Render Queue/Batch Render tool for After Effects.
Automatically searches for latest versions of After Effects Projects
in a specified folder and adds to the queue. You can then choose to
remove or add other After Effects Projects. The tool will render
everything in each After Effects Project’s Render Queue using multiple
processors if available.
Requirements:
------------
This tool has been created and tested on windows but should work on Mac and Linux too.
It requires Python and PyQt be installed.
I’m using Python 2.6 and PyQt 4.9.6.
Demo Video: http://www.youtube.com/watch?v=3ktHj_PDI0M
After Effects Blog: www.codingForAfterEffects.wordpress.com
Logic:
------
1. Prompt user for root folder in which to search for all ".aep" files.
2. Get the latest versions (by highest version number) of all ".aep" files found in
the user specified root and all child directories.
3. Allow user to add or remove files from the queue.
4. Render the files in the queue in order when the render button is clicked.
4.1 Find the "aerender" executable.
4.2 Start a thread to render the aep files.

请用外行人的语言回答，因为我不知道很多python术语。 如果可能，请直接提供修改后的代码。
感谢和问候。 的网站，我得到这个代码的链接是https://www.highend3d.com/downloads/applications/render-managers/c/after-effects-render-queue
感谢ü非常现在工作正常 –
