summary
Concrete claims and engineering tradeoffs dominate: AV-1 published and an AVIF image format is imminent, the Alliance has >30 members and licensing is viral not patent‑free, and Netflix experiments with autoplaying video for discovery. Technical tools covered are PQ and HLG curves, dynamic metadata (SMPTE 2094) and color‑volume transforms. The big unresolved engineering fact is the HDR tone mapping problem when compositing SDR/HDR assets and that HDMI lacks reliable display metadata so tone mapping often ends up on the panel.
