HDRformater

HDRformater is a cross-platform software tool designed to format and convert High Dynamic Range HDR media for professional and consumer workflows. It focuses on converting between HDR formats, managing color spaces, and translating HDR metadata during processing.

Core features include support for HDR formats such as HDR10 (BT.2020 with PQ), HDR10+ (dynamic metadata), HLG, and Dolby Vision when available through optional modules. It can perform color space conversions between Rec.2020 and Rec.709, apply tone mapping, adjust peak luminance, and re-encode to 10- or 12-bit depth. It also handles metadata—static Mastering Display Color Volume and Content Light Level, plus dynamic metadata for compatible pipelines. Output is packaged into common containers (MP4, MKV) with batch processing available via a command-line interface and an optional graphical user interface.

Technical notes: HDRformater analyzes input metadata, reconstructs or preserves HDR intent during re-encoding, and can generate or adapt dynamic metadata as needed. It relies on external codecs and can use hardware acceleration where available. The tool is designed for mastering engineers, post-production teams, and streaming publishers to ensure consistent HDR delivery across platforms.

History and development: HDRformater emerged in a community-driven project in the mid-2020s as an open-source initiative. Documentation outlines supported formats, licensing terms, and integration guidance for common editing and publishing pipelines. The project encourages contributions and provides examples and test assets.
