You publish your Dynamic Media assets by selecting the assets and tapping Publish. After your dynamic media assets are published, they are available to you for including in a web page via URL or by way of embedding.
You can also instantly publish assets that you upload—without any user intervention. See Configuring Dynamic Media - Scene7 mode.
In the Card View, a small globe icon appears directly below an asset’s name to indicate that it is published. In the List View, a Published column indicates which assets are published or which are not.
If an asset is already published, then you use AEM to move the asset to another folder, and re-publish from its new location, the original published asset location is still available, along with the newly re-published asset. The original published asset, however, is “lost” to AEM and cannot be unpublished. Therefore, as a best practice, unpublish assets first before you move them to a different folder.
If you intend to publish video assets immediately after encoding them, make sure encoding is completely done. When videos are still being encoded, the system lets you know that a video processing workflow is in progress. When video encoding is done, you should be able to preview the video renditions. At that point, it is safe for you to publish the videos without incurring any publishing errors.

AEM now supports the delivery of all Dynamic Media content (images and video) over HTTP/2. That is, a published URL or embed code for the image or video is available to be integrated with any application that accepts a hosted asset. That published asset is then delivered by way of HTTP/2 protocol. This method of delivery improves the way browsers and servers communicate, allowing for better response and load times of all your Dynamic Media assets.
