Meta enables Dolby Vision HDR on Instagram with compressed metadata – PPC Land

Meta announced on November 17, 2025, that Instagram for iOS now supports Dolby Vision and ambient viewing environment metadata for HDR videos created on iPhones. The implementation addresses technical challenges in preserving iPhone-produced video metadata through Meta’s server transcoding pipeline, marking the social media platform’s first comprehensive HDR video enhancement since initial HDR support launched in 2022. The development required Meta’s engineering team to implement compressed Dolby Vision metadata formats, reducing overhead from 100 kbps to 25 kbps per video on average. According to the announcement, this compression improvement proved essential after initial A/B testing in 2024 revealed that uncompressed metadata increased video load times enough to reduce user engagement on Instagram Reels. Every iPhone-produced HDR video encoding includes two critical metadata components that Meta’s previous transcoding system discarded. Ambient viewing environment metadata provides characteristics of the nominal viewing conditions, enabling devices to adjust video rendering based on actual ambient light. Dolby Vision metadata enhances color, brightness, and contrast to match the video to display capabilities. Meta’s video processing infrastructure operates across three stages: client processing where creators’ devices flatten compositions into HEVC-encoded files with Main 10 profile, server processing where transcoding systems generate multiple format versions, and consumption where
