Google has launched Eclipsa Video, its branded implementation of the SMPTE ST 2094-50 open HDR standard developed alongside Apple and NBCUniversal. The format targets HDR's core inconsistency: a scene that dazzles on a premium TV often crushes shadows on a phone or blows out highlights in a dark room. Eclipsa aims to deliver "consistent, balanced and comfortable" playback across every screen by adapting to each display's capabilities and, on supported hardware, ambient lighting conditions.

The system relies on two metadata mechanisms. A white reference anchor sets a baseline for mapping SDR content's brightest elements while reserving headroom for HDR highlights. Headroom-adaptive gain curves then let creators embed custom instructions so displays that can't hit the video's peak brightness still render the intended effect. This dynamic approach mirrors Dolby Vision, though Dolby's format remains proprietary. HDR10 uses static metadata for an entire video, while HDR10+ adds dynamic metadata but lacks Eclipsa's ambient-light awareness.

Platform-wide playback and capture support arrives with Android 17, extending to phones, tablets, and TVs. Adoption hinges on device makers, streaming services, and content providers embracing the standard. If widely implemented, Eclipsa could finally make HDR behave predictably whether you're watching in a bright living room or a pitch-black bedroom.
