Using AWS Elemental MediaConvert output groups to specify a streaming package type or standalone file

An AWS Elemental MediaConvert output functions differently depending on which type of output group it is a part of.

File

In a File output group, each output you set up results in a standalone output file.

For example, you might set up one output that contains all the video, audio, and captions together. And you might also set up a separate output for sidecar captions, such as TTML.

Streaming output packages

In the following output groups, the outputs you set up are separate parts of a single adaptive bitrate (ABR) streaming package: CMAF, Apple HLS, DASH ISO, and Microsoft Smooth Streaming.

In an ABR output group, each output is usually one element of the media. That is, each output is one slice in the adaptive bitrate (ABR) stack. For example, you might have an output for each of three resolutions of video, an output for each of two audio language tracks, and an output for each of two captions languages.

The following illustration shows the relationship between outputs in an ABR output group and the files that MediaConvert creates. Each orange box corresponds to an output within the output group. In this example, there are three resolutions of video, audio in two languages, and captions in two languages. The package contains segmented audio, video, and captions files and manifest files that tell the player which files to download and when to play them.


                Each rendition in an ABR stack has its own output in the output
                    group.

A single job can generate zero to many standalone files and zero to many streaming packages. To create more than one standalone file, add a single file output group to your job and add multiple outputs to that output group. To create more than one streaming package, add multiple CMAF, AppleHLS, DASH ISO, or Microsoft Smooth Streaming output groups to your job.

The following illustration shows an MediaConvert job that generates two standalone .mp4 files, two Apple HLS packages, and a CMAF package.


                A single file output group with two outputs results in two standalone files.
                    A single Apple HLS output group with seven outputs results in a single viewable
                    package with seven ABR slices.
