Important notes about HDR and 10-bit:
- HDR and 10-bit can only be encoded with AV1 and HEVC encoders.
- 10-bit HEVC encoding requires NVIDIA 10-series, AMD 5000 series, or newer GPU. Intel QuickSync and Apple VT are not yet supported.
- The recommended settings for HDR are Color Format P010 and Color Space Rec. 2100 PQ.
- If you wish to encode 10-bit SDR, you can use Color Format P010 with an SDR color space (e.g. Rec. 709, Rec. 601). However, AV1 or HEVC will still be required.
- HDR streaming is currently only supported via YouTube"s HLS service via an HEVC encoder.
- When composing in SDR, games that operate in HDR can now be properly tonemapped to SDR.
- Video capture devices can be used to capture and stream in HDR if the device supports it (e.g. EVGA XR1 Pro, Elgato 4K60 Pro Mk.2, AverMedia Live Gamer 4K).
- For a list of tested devices, see https://obsproject.com/kb/video-capture-devices-with-hdr-support
- Certain filters will not function if a source is rendering with HDR:
- Apply LUT, Chroma Key, Color Key, Image Mask/Blend, Luma Key, Sharpness
- Mac/Linux support is limited. HDR preview does not work, and several inputs/encoders still need to be updated. [full release notes]
