Broadcast technology specialist Grass Valley has launched the newest version of Rio, its online editing and post-production suite.

With version 4.5.3, Grass Valley says that the Rio now provides faster, more flexible workflows to support Dolby Vision deliverables. With a Dolby CMU box, timeline trim passes can now 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 the company says results in faster workflows on projects with long timelines.

Grass Valley is also claiming 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 claimed to be 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.

Other features include additional support for BT.2020 Hybrid Log Gamma colour space and gamma curve to handle HDR and SDR in a single signal, while its Alchemist re-speed algorithm has also been updated to provide improved stability and results.

“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,” remarked Katsushi Takeuchi, vice president and general manager of editing, Japan, Grass Valley. “These new enhancements further fuel our customers’ ability to deliver stunning images at any resolution or framerate.”
