Uploading Watermark Images
Once you have made the required configuration changes to your
publication's content-type
resource, and uploaded
it to the
Content Store,
you can upload the watermark images you want to use. Start
Content Store
and create a watermark content item for each watermark. You will be
prompted to supply an image file to upload. Note that the image file
you supply must have one of the following file
extensions:
.jpg
.jpeg
.png
The file extension must be lower case as shown above. Amazon Elastic Transcoder uses the file extension to determine the file type, and only recognises these three extensions. A file with a different extension will be rejected even if it is in fact of the correct type.
Once you have created each content item, make a note of its ID, as you will need to use it when adding section parameters to the publication.
