6. Set the HDR format:
• HDR10: By default, iTunes Store packages transcode HDR video to the HDR10 format,
so no further modifications are required.
• Dolby Vision: Open the Job inspector, then in the Dolby Vision Metadata area,
click Choose, navigate to an XML file formatted using the Dolby Vision metadata
specifications, and click Open. When you attach a Dolby Vision metadata file,
Compressor transcodes your iTunes Store package to a format compatible with both
HDR10 and Dolby Vision. When a user rents or purchases HDR content, the iTunes
Store plays the highest-quality version compatible with the user’s display device.
Note: Dolby Vision submissions must be mastered at a Dolby Vision–certified facility.
See the Dolby Vision website.
7. In the Video inspector, click Choose in the “QuickTime settings” area, then choose
either Apple ProRes 4444 or Apple ProRes 4444 XQ from the pop-up menu.
HDR package submissions to the iTunes Store must use the Apple ProRes 4444
or Apple ProRes 4444 XQ codec. If you choose a different codec, your package
submission will fail.
8. Complete your iTunes Store package by configuring package settings; adding subtitles,
closed captions, alternative audio tracks, and chapter markers; and then building
the package.
Important: Compressor can’t directly submit the package to the iTunes Store. See
About submitting to the iTunes Store in Compressor.
Build a supplemental HDR upgrade to an already available SDR video
If the SDR version of your feature video is already available in the iTunes Store, you can
submit the HDR version by itself as a supplemental upgrade package.
1. In Compressor, choose File > New iTunes Store Package.
An iTunes Store Package job appears in the batch area.
2. Do one of the following:
• Drag an HDR video file from the Finder onto the Feature row.
• Click Set on the right side of the Feature row, select an HDR video file, then
click Open.
An output row containing the selected video file (and an HDR badge) is added to the job.
3. If you want to modify the color space of the video for the iTunes Store package, open
the Video inspector, click the “HDR color space” pop-up menu, then choose either Rec.
2020 PQ or P3 D65 PQ.
Either option is compatible with the two HDR formats supported by the iTunes Store—
Dolby Vision and HDR10.
