我不是专家脚本。我试图专门搜索这个，我发现的一切都与导出图像序列有关。我搜索并发布在AskDifferent上。我想要做的是从.mp4文件的开头和结尾导出一个.png文件。这是一个高度重复的任务，我最近做了很多，我真的想自动化它。例如，我们前几天处理了超过100个.mp4s，导致所有开始和结束.png文件花了一个多小时。如果有一个应用程序可以自动执行此操作，那么QuickTime就可以了。我只是想尝试自动化一个真正重复的任务，所以我认为applescript和QuickTime将是解决方案。
我使用的是QuickTime Pro 7 7.6.6版。我使用导出命令来获取与我的视频文件大小相同的静止帧。
我开始使用Apple递归脚本作为基础，这是我到目前为止所做的，但它不起作用。我在这里发帖，希望有人可能知道我错过了什么。

(* INSTRUCTIONS
This droplet is designed to process one or more files, or folders containing files, whose icons are dragged onto the droplet icon.
The droplet processes recursively, and will examine the contents of every dragged-on folder, and every sub-folder within those folders, to find and process any files who kind matches the indicated types.
You can set the droplet to process only files of a specific type, such as images, by adding the appropriate data types, name extensions, and type IDs to the values of the properties listed at the top of this script.
Place your script code for processing the found files, within the process_file() sub-routine at the bottom of this script.
