50 CREATE & PRODUCE BY DAVID FOX
Cooke Optics has introduced two full-frame zooms, the 30-95mm and 85-215mm Varotal/i T2.9 lenses. They cover all full-frame sensors and are matched in resolution, colour and fall off to the Cooke S7/i range, to provide a complete suite of Cooke full-frame spherical lenses. The lenses can be fi tted
with either PL or LPL mounts at time of order. Tim Pugh, CEO, Cooke Optics, said: “Fifty years after the launch of the fi rst Varotal lenses, we are proud to bring these new Varotal zooms to our customers. They are now able to choose an entire colour- matched Cooke line, complete with the Cooke Look, for their full-frame productions.” Like all modern Cooke lenses, the Varotal/i zooms include /i Technology to record lens data, and are optimised to capture warmth, texture and
beautiful skin tones. The lenses can be used handheld or with Steadicam, and are claimed to provide comfortable balance with the latest digital cinema cameras.

INTRAPLEX ASCENT NOW A REAL LIVEWIRE GatesAir
PUBLISH BY DAVID FOX
GatesAir has added native Livewire+ IP audio networking support to its Intraplex Ascent cloud transport platform, which removes conversion stages when transporting multiple audio streams between studios. This adds a new layer of scale and effi ciency for radio broadcasters managing many digital audio channels between
at full aperture with superior control of fl are, distortion and spherical aberration.
GatesAir Intraplex Ascent now streams audio at scale without conversion
studios. Future support is planned for WheatNet-IP, further expanding Ascent adoption within professional broadcast studios. GatesAir introduced Intraplex
Ascent as a next-generation audio-over-IP platform built to transport broadcast and media content at scale. It was built with broadcast and IT convergence in mind, leveraging common
off-the-shelf hardware to reduce the costs of multichannel contribution and distribution between many locations. It started shipping last year and there are a number of systems in operation with broadcasters now, including one recent deployment with Livewire+ capability. Keyur Parikh, vice president of engineering, GatesAir, said: “GatesAir has successfully deployed Ascent with a national radio broadcaster that is sending 32 audio channels between two major studio locations. They are directly connecting to the
NXTEDITION GOES PUBLIC WITH NXT|CLOUD nxtedition
MANAGE BY DAVID FOX
Broadcast microservice specialist nxtedition has enhanced its consolidated production and playout platform with nxt|cloud, a complete deployment of nxtedition in the public cloud. Previously, playout in
nxtedition utilised the switching, layering and real-time rendering power of CasparCG to achieve high production values using COTS hardware. This latest development is a fully containerised, Linux version of CasparCG, providing the same playout functionality, fl exibility

and quality as a scalable, elastic and secure microservice in the cloud. Entirely built in JavaScript, the platform can take advantage of all developments in web technology.
The nxtedition system contains
all the elements required for broadcast, from ingest and transcode through asset management and archiving to delivery to multiple platforms, automatically repackaging news stories for social media. Being
fully virtualised means that systems can be built to precisely match individual workfl ow requirements.
Adam Leah, nxtedition’s
creative director, said: “With nxt|cloud we can offer an
Livewire studios, providing encoding and reliable transport across public IP networks. Our high-density platform ensures seamless integration into Livewire networks without the need for audio converters.” The system uses GatesAir’s Dynamic Stream Splicing (DSS) software to support reliable transport across redundant networks, and optimises stream integrity through protection against jitter, packet losses and network failures. Within Ascent, DSS also supports duplication of SRT streams with video and audio over separate network paths.
identical experience in the cloud: the same quality, the same functionality, the same user experience, the same responsiveness. That includes sophisticated added-value features like localisation: we can, for example, take in a single live sports feed over SRT and split [it into] eight identical CasparCG channels, but sending each channel a separate commentary audio and graphics feed in different languages – all driven by the timestamped metadata authoring and the layering in nxtedition.”
The system is also designed
to provide on-prem clients with hybrid cloud backup for disaster recovery. Playout channels are mirrored, as are scripts and media. In an emergency, the entire team can switch to the cloud and continue working.
