我正在使用Simple Serverless Video On Demand template在AWS上部署VOD解决方案。我更新了代码，为所有无法在那里处理的视频添加了水印。视频正在被转码，但是水印仍然缺失，到目前为止，我已经尝试了两种方法：
但是似乎没有一个起作用。测试视频的尺寸为320×240，这是正在生成的作业请求的内容：

答案 0 :(得分：0)
我看到您已将TimecodeConfig和TimecodeSource设置为EMBEDDED。我还注意到您的图片插入器均从00：00：00：00开始。
MediaConvert将在视频的SEI标头中查找基于嵌入式时间码的时间码。您可以查看mp4文件，看看它是否确实嵌入了时间码。或尝试使用和重新运行您的工作流程，并将TimecodeConfig和TimecodeSource切换为ZEROBASED。这将告诉服务从0开始并打勾。
请注意，MP4和MOV文件可能包含一个tcmd框（原子）。但是，诸如MediaInfo之类的普通阅读器会将其视为时间码，并显示为单独的音轨。
