安费诺传感器应用介绍和Python添加视频字幕示例

本文中，我们延续上次慕尼黑上海电子展的热度，两位销售经理通过视频的方式推介了我们在工业、医疗和新能源车等方面应用的若干款产品。时间有限，难以涵盖更多的产品和深入说明。

若您需要了解更多的产品和应用内容，可以直接联系我们。

另外，本文提供了如何给视频添加字幕的Python示例代码。本文中视频的字幕添加即通过下面的示例代码实现。

视频-1 安费诺传感器的工业和医疗应用

视频-2 安费诺传感器的新能源车应用

附：

一. Python为视频添加字幕

添加字幕时，需要把要添加的文字内容事先准备好，和视频内容和时间段契合。读取原视频后，处理之后的视频会另起名存储。请按照实际的文件名称路径进行调整。

下一篇里，我们会通过Python将两个视频进行拼接和加二维码。

再下一篇里，我们可能会聊一下PID控制器参数的自动优化的实现。
