Grass Valley Delivers the Ultimate Post Production Workflow with Rio 

Grass Valley, a Belden Brand, launched the newest version of Rio, the high performance online editing and post production suite, providing users with even more functionality including Dolby Vision support and best-in-class file compression for increased media availability on existing storage.

The solution will be showcased at Inter BEE 2018 (November 14-16, Tokyo, Grass Valley Hall 3/3506).

The latest updates included in Rio v4.5.3:

  • Dolby Vision Support: Rio provides faster, more flexible workflows to support Dolby Vision deliverables. With a Dolby CMU box, timeline trim passes can now easily be made across multiple display devices with all information stored in a single XML. All parameters can be controlled from the Neo panel with frame analysis choices that result in faster workflows on projects with long timelines.
  • Near Lossless Rendering: Introducing a new compression codec, based on VC-2, that enables Rio to run from 2:1 to 6:1 compressed to disk (in addition to its standard uncompressed mode). If compression is selected, and once media is compressed onto a disk, the codec is virtually lossless across multiple renders, enabling users to store additional media at the same chosen compression ratios, increasing storage capacity by factor of 2-6 times.
  • Canon V2.2 SDK HDR/SDR Update: With additional support for BT.2020 Hybrid Log Gamma color space and gamma curve to handle HDR and SDR in a single signal. Rio also provides added functionality with resize and debayer modes and camera name display.
  • Improved Stability: The Alchemist re-speed algorithm has also been updated to provide improved stability and results.

Rio More color

Katsushi Takeuchi, vice president and general manager of editing, Japan, Grass Valley commented: “With a strong heritage for pushing the industry’s boundaries for performance and creativity, Rio is a hallmark for the highest quality post production and finishing – from its real-time performance to its complete, integrated toolset and ultra-fast workflows. These new enhancements further fuel our customers’ ability to deliver stunning images at any resolution or framerate.”
