Connected 4K workflow—from the studio to the cutting room floor
Nagoya Broadcasting Network’s (NBN) aim is to become one of Japan’s leading stations in next generation broadcasting. Cementing this approach is the broadcaster’s adoption of state-of-the-technology to enable the production and delivery of 4K and HDR content. With investment in the latest Sony cameras and monitors to capture 4K content in 2015, NBN sought to extend its 4K capabilities from the studio floor into the cutting room.
An existing Avid customer, NBN quickly realized the potential of a connected workflow enabled by Avid Everywhere and powered by the Avid MediaCentralplatform. Investment in the latest Avid 4K solutions, backed by scalable storage, has taken the broadcaster’s 4K production to another level.
Building out a dedicated 4K editing and finishing room, NBN’s first 4K project was a special edition of the entertainment show, BOMBER-E Dance Night. Mr Minoru Murata, head of NBN’s technology strategy department, technology office, said, "Since NBN’s talks on next generation broadcasting in 2013 lead by President Masahiko Yokoi, we’ve taken steps to create frameworks within the station and began by experimenting with 4K camera productions tied to the popular dance shows in our catalog.”
We decided the best solution would be for us to make the investment in Avid’s latest 4K solutions and gain knowledge of doing it ourselves.

Delivering 4K content
Realizing the pressure to remain operationally efficient, the broadcaster accessed its 4K production chain further and realized the benefits of moving editing 4K content in-house. Mr. Hirotaka Tsutsui, deputy manager of the technology strategy department, adds, "While we were involved in 4K production as content makers, we were outsourcing 4K editing which wasn’t helping us to grow our knowledge base and editing know-how.”
He continued, “Factoring in the many format changes required for offline editing, the introduction of Avid Media Composer with the Avid Artist | DNxIQ (formerly Avid Artist | DNxIO) video interface enables us to be an integrated production house for 4K programming, from capture through to final finishing, all under one roof.”
With an existing Avid editing suite at the station for HD productions, NBN also upgraded it to the latest version of Media Composer. This ensured both the new 4K suite and existing HD one were compatible and interlinked by Avid NEXIS shared storage so assets can be shared between suites.
Editor, Mr Hiroaki Tanaka, shares his 4K editing experience, “The editing operation felt very familiar and the same as HD editing. The codec we use is Avid’s proprietary Avid DNxHR so 4K editing was a similar operational feel to what we’ve been used to. Our editing workflow comprises generating proxy data (HD) from 4K master data, offline editing, and adopting the AAF file as edit data and converting it to a 4K editing file format.”
Driving new revenue from 4K production
As the only 4K editing facility in the Tōkai region, NBN plans to offer the suite for hire to external production companies. And with 4K content currently being broadcast in Japan via satellite or IP video streaming, NBN’s business model to maximize the use of the suite is evolving. Hirotaka Tsutsui, concludes, "We’re considering using our 4K capabilities to produce large-scale videos for events, providing signage content, as well as compacting down to HD videos and rolling it out for regular broadcast or satellite broadcast.”
