Choose Include to have MediaConvert generate an HLS child manifest that lists only the I-frames for this rendition,
in addition to your regular manifest for this rendition. You might use this manifest as part of a workflow that
creates preview functions for your video. MediaConvert adds both the I-frame only child manifest and the regular
child manifest to the parent manifest. When you don't need the I-frame only child manifest, keep the default value
Exclude.
