Runway Launches Ruby: One-Click SDR-to-16-bit HDR Video Conversion
Runway launched Ruby on August 21, a new model that upscales SDR video to up to 16-bit HDR, covering all uploaded or AI-generated videos up to 30 seconds on the platform. The feature is live for Max plan and enterprise users, filling a long-missing HDR gap in professional video workflows.
Confirmed
- Ruby converts SDR video into 16-bit EXR sequences or 10/12-bit ProRes and HEVC formats, supporting BT.2020 color gamut and PQ/HLG transfer standards.
- It applies to any uploaded or generated video up to 30 seconds, including live-action and generated content.
- Availability is limited to Max plan and enterprise users.
- 16-bit HDR (ProRes and EXR sequence) export support applies to all video generation models on the Runway platform.
- Per @AIAndrew, officials called it one of the community's most requested features in 8 years, with more updates coming in the following weeks.
Why it matters
- HDR with high bit depth and wide color gamut is essential for professional post-production and color grading; Ruby lets AI-generated content enter professional pipelines directly, solving, as @Vjeux noted, the problem of generated footage not being usable in final-pixel pipelines.
- Support for industry-standard formats like EXR/ProRes lowers integration costs with tools such as DaVinci Resolve.
