Grass Valley delivers on 4K editing

Japan’s Kansai Telecasting Corporation based in Osaka, has migrated to a full 4K editing system, plus newsroom systems from Grass Valley.

Japan’s KTV, the Kansai Telecasting Corporation based in Osaka, has migrated to a full 4K editing system, plus newsroom systems from Grass Valley. The station has purchased the Edius HDWS 4K desktop turnkey system and Edius Elite HDWS 3GX system for realtime 4K editing.

KTV also bought the GV Stratus Nonlinear Media Production system and K2 Summit media server for a complete, file-based workflow to be used in conjunction with Edius for editing across its newsroom operations.

Grass Valley had demonstrated 4K and future 8K support for Edius at InterBEE in Japan last November, which impressed KTV staff. “After seeing 4K and 8K demonstrations of Edius at InterBEE last year, we decided that the software was the real lynchpin in our 4K plan and the right purchase for our organisation,” explained Takashi Nogami, deputy manager of videotape and editing division at KTV. “Edius is such great value because not only does it let us edit in 4K, we can also convert between different resolutions, aspect ratios, and frame rates in realtime. It really lets us focus on creativity so we can deliver higher quality content to our viewers.”

Support for editing at higher resolutions in Edius is made possible by Grass Valley’s HQX Codec, which dramatically improves editing response time and is the key technology behind its realtime capabilities. Supporting 4K today as well as 8K in the future, with a native 64-bit architecture, Edius 7 is the latest version of Grass Valley’s editing software (the first version of which was launched ten years ago), is compatible with all major file formats and can edit in real time without rendering.

Ahead in the clouds

Grass Valley will provide users of Edius 7 with the ability to transcode to a streaming format directly from their HQ/HQX assets, using Microsoft’s Azure Media Services. Microsoft has licensed support for the HQ and HQX codecs, which should offer Edius users improved functionality and the flexibility to upload and stream content to a wider variety of environments through the cloud. Edius 7 runs on Windows 7 and Windows 8.

“The number of different sources and formats that content producers are working with is mirrored by the growing number of delivery formats that end users are demanding—whether that means video files, web streams, podcasts, or a host of other formats,” said Mike Cronk, senior VP strategic marketing, Grass Valley.

The Microsoft Azure cloud-computing platform includes infrastructure for building, deploying, and managing applications and services through a global network of Microsoft-managed data centres. It enables users to create, manage, and distribute media in the cloud, with support for a multitude of programming languages, tools, and frameworks.

“When faced with a complex assortment of input sources, a demanding creative brief, and a tight deadline, the speed and transparency benefits of intermediate codecs are hugely significant,” said Sudheer Sirivara, director, Microsoft Azure Media Services. “Grass Valley’s HQ and HQX codecs provide a combination of unrivalled advantages that add up to increased creativity for content producers and editors, and ultimately increased value to our clients.”

DaVinci Resolves to integrate Edius

The latest version of Blackmagic Design’s DaVinci Resolve colour correction software (version 11) also has support for the HQ and HQX codecs, which should offer users a much more streamlined workflow.

It will provide Edius users with a smoother import and export, with quicker access to Resolve’s powerful and creative colour correction toolset.

The HQ/HQX intermediate codecs will sit in a .mov container, so that users can import raw 4K files directly into Resolve, colour correct as required, and then export the clip as an HQX file directly into Edius. It will also allow editors to exchange projects in EDL format (AAF exchange support is scheduled for a future release of Edius), which would allow a round trip workflow between Edius and DaVinci Resolve in HQX.
