You can deliver Dolby Vision HDR video without a corresponding SDR video delivery and specify a tag to down-convert to SDR. Apple will create the SDR video using the Dolby Vision SDR trim metadata. Using this method is optional, but it could streamline the delivery process for you. When you deliver a Dolby Vision-only package, you can choose to include embedded audio or you can deliver the audio in a separate file.
Note: This delivery method is not available for HDR 10 videos.
To deliver a Dolby Vision-only package, you must use the attribute that indicates you want the HDR video to be down-converted to SDR: <attribute name="video.hdr.force_sdr_downconvert">true</attribute>.
This example shows how to deliver Dolby Vision HDR video without an SDR video delivery. When you deliver a Dolby Vision-only package, you can choose to include embedded audio or you can deliver the audio in a separate file. In this example, the HDR full source video includes embedded audio. Since there is no SDR audio in this delivery (the default audio source), the HDR source is used as the primary audio source. Both Dolby Vision CM version 2.9 and CM version 4.0 sidecar metadata files are supported.
