Delivering HDR

HDR requires new delivery and mastering practices: HEVC or VP9 for delivery, most HDR sets ship as 4K, and you must use a separate transcode stack for HDR versus SDR (no ABR flip). Use 10‑bit with an EOTF (PQ or HLG), expect displays to target 800–1,500 nits though PQ nominally maps to PQ 10,000 nits and HLG intentionally scales to ~4,000 nits and is HLG backward compatible with SDR. Watch out for 10% patch peak measurements, encoder RDO updates, and use affordable capture like Blackmagic (13–15 stops) and Intensity Pro 4K for real 10‑bit output.
