Starting today, you can create video on-demand clips or programs from an AWS Elemental MediaPackage live channel. By making a live-to-VOD request with an IN and OUT time reference along with a Channel endpoint ID, MediaPackage will create a segment accurate asset and export it to your Amazon S3 bucket. You can then ingest that asset into a MediaPackage VOD packaging group to have it available in all the same formats as the live channel. For more details, please refer to the relevant Live-to-VOD and VOD packaging documention pages.
