Additional MP4 options are now available, including audio-only MP4 option; "standard" is now deprecated.

The mp4_support field used to create static MP4 renditions for an asset now supports 3 new options, including an option to produce an audio-only MP4. These should be used instead of the now deprecated standard value.

• capped-1080p, which produces a single MP4 rendition up to 1080p in resolution.
• audio-only, which produces a single audio-only MP4 rendition.
• audio-only,capped-1080p, which produces both.

Full details can be found in the updated MP4 Guide.
