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.

运行时出现以下错误.这很令人沮丧.
I get the following error when i run it. It is very frustrating.
Qt: Untested Windows version 10.0 detected!
Traceback (most recent call last):

self.emit(SIGNAL("STARTED"), aepPath)
AttributeError: 'RenderThread' object has no attribute 'emit'
TypeError: single_render_started() missing 1 required positional argument: 'aepPath'
TypeError: single_render_finished() missing 1 required positional argument: 'aepPath'
请用外行的语言回答，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.
Please answer in layman's language as I don't know a lot of python terminology. If possible please provide the modified code directly.
谢谢和问候.我获得此代码的网站链接是 https://www.highend3d.com/downloads/applications/render-managers/c/after-effects-render-queue
Thanks and regards. The link to the website where I got this code is https://www.highend3d.com/downloads/applications/render-managers/c/after-effects-render-queue
推荐答案
导入类的问题，一个简单的解决方法就是在import的部分放置如下:
The problem of importing classes, a simple way to solve is to place the following in the part of imports:
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
plus:另一个可能的错误是代码使用了旧的连接样式，如果有错误，请更改以下内容:
self.connect(renderThread, SIGNAL("STARTED"), self.single_render_started)
self.connect(renderThread, SIGNAL("FINISHED"), self.single_render_finished)
到:
renderThread.started.connect(self.single_render_started)
renderThread.finished.connect(self.single_render_finished)
