Upload High Dynamic Range (HDR) videos
You can upload High Dynamic Range (HDR) video content to YouTube. HDR videos show higher contrast and more colors than standard digital video.
Viewers can watch HDR videos on an HDR TV. They can also stream HDR videos using Chromecast Ultra to an HDR TV. Viewers can confirm HDR playback when a video is played if they see an "HDR" badge along with player controls.
Viewers watching on non-HDR devices will see the video as a standard dynamic range (SDR) video.
Upload HDR videos
Videos must have HDR metadata in the codec or container to be played back as HDR videos on YouTube. The most reliable way to properly record the metadata is to export from a supported application, such as BlackMagic DaVinci Resolve 12.5.2.
If you use a different workflow to grade in HDR, then you can use the YouTube HDR metadata tool to add HDR metadata to a video. This tool will only work correctly if your video was graded using an HDR transfer function.
If you are grading your video, take care to grade in Rec. 2020 with PQ or HLG. Using a different configuration, including DCI P3, will produce incorrect results.
Once a video has been properly marked as HDR, uploading it follows the same process as a normal video upload. YouTube will detect the HDR metadata and process it, producing HDR transcodes for HDR devices and an SDR downconversion for other devices. Note: HDR videos currently can't be edited with YouTube Web editor.
HDR video requirements
Once you upload a video, YouTube supports all resolutions and will auto-convert HDR video to SDR videos when necessary.
|Resolution||720p, 1080p, 1440p, 2160p
For best results, use UHD rather than DCI widths (e.g. 3840x1600 instead of 4096x1716).
|Frame rate||23.976, 24, 25, 29.97, 30, 48, 50, 59.94, 60|
|Color primaries||Rec. 2020 or Rec. 709|
|EOTF||HLG (BT.2100)* or PQ (SMPTE ST 2084)|
|Video bitrate||For H.264 encoded, use the recommended upload encoding setting.|
|Audio||Same as the recommended upload encoding setting|
* HLG playback currently has limited playback support.

HDR authoring tools
Blackmagic's DaVinci Resolve software, version 12.5.2 or newer, exports some HDR metadata. It's currently the only software that exports files with standards-compliant metadata out of the box. To take advantage of this:
- Go to Project Settings.
- Under "Master Project Settings," choose DaVinci Resolve YRGB Color Managed as the Color Science.
- Go to the "Color Management" page.
- Choose either ST.2084 1000 or HLG-2020 as the Output Color Space.
This container and codec doesn't yet support all metadata. It specifies primaries, transfer characteristics, and matrix coefficients, but doesn't provide mastering display metadata.
Incorrect color space marking
SDR auto-conversion issues
- Start by loading your HDR deliverable into a color grading application without applying any color management.
- Set your mastering display to Rec. 709 color and Gamma 2.4 transfer function.
- Apply an existing LUT that converts from Rec. 2020 + ST. 2084 to Rec. 709, and then in subsequent nodes, adjust primary correctors, curves, and keys to get the look you want.
- Export the LUT in the .cube format to the same folder as the HDR deliverable.
- Select both the LUT and the HDR video, and drag and drop them on the metadata tool.
The tool will apply metadata for the BVM-X300, and also pack in the LUT to provide hints to the SDR downconversion.
