How to create blurred background of the same video input with AWS MediaConvert?
问题
可以使用AWS MediaConvert为一段肖像视频创建一个模糊的次要层，以填充整个帧吗？我正在尝试实现这个结果。
英文:
Is it possible to create a secondary layer for a portrait video with AWS MediaConvert, of the same video but blurred, and that fills the frame?

目前服务中没有模糊效果，因此需要在源文件上执行单独的操作。这可以通过 AWS Lambda 自动化处理。
<p>
生成所需背景图像的一种方法可以使用此处找到的 ImageMagick Lambda 层：
https://serverlessrepo.aws.amazon.com/applications/us-east-1/145266761615/image-magick-lambda-layer
上述 Lambda 将生成一个背景图像，您可以将其用作输入到您的 MediaConvert 作业的附加输入。这个过程可以通过 Lambda 和 S3 文件事件（新文件到达事件）进行自动化和触发。
英文:
There is no blur effect within the service at this time, so it would require a separate operation on the source file. This could be automated with AWS Lambda.
<p>
One method to generate the desired background image could use the Image magick Lamba layer found here:
https://serverlessrepo.aws.amazon.com/applications/us-east-1/145266761615/image-magick-lambda-layer
The Lambda described above would generate a background image which you can then use as an additional input to your MediaConvert job. This process could be automated and triggered via Lambda and S3 File Events (new file arrival event).
