The Workflow Guest Opinion
cloud that is particularly acute for production companies and content owners. That barrier is intangibility. Before its appropriation by the IT industry, a cloud as traditionally defined was, after all, just vapour. Some content owners struggled with the transition from tapes to black box disk arrays that sat in a closed technical area in the basement. For many, the thought of valuable archive content or rushes being stored in a virtual black box at a remote data centre is an uncomfortable step too far. And there may be genuine, well-founded concerns in respect of security, reliability and the economic stability of the service providers.
Back on earth Does the service provider own outright the hardware on which the content is stored? Does the service provider own the building in which the hardware is stored? What happens if the provider goes bust? These very real questions should be a caution to broadcasters and content
material available for purchase through web portals. Equally, collaborative production and post production workflows can be transformed with, for example, core asset management systems provisioned from the cloud enabling geographically disparate users to share, log and edit material via a low bit

rate browse proxy. This is a genuinely transformative innovation with relatively low set up and operational costs. At a broadcast facility back on earth, the denser, high bit rate master material resides on HSM-based storage and is processed locally with job management control between a cloud-based management system and ground-based video processing services using secure, open protocols and standards. In order to properly see the benefit of the cloud-based model, which can be described as scalable capacity in a burstable manner (rapidly scaled up and down as throughput needs dictate) and a pay-per-use charge model, the ground deployment needs to be designed accordingly. Video processing
capabilities have to be decoupled from proprietary
hardware and moved onto commodity IT infrastructure
to become truly service-based software components. Processing functionality should also conform to service- orientated architecture to allow rapid increases in capacity while leaving system resources free for use by other processes.
The last component is the
pay-per-use access model. Over the summer of 2012 BLM is making a series of announcements about metered, pay-per-use services. Broadcasters and content owners will soon be able to deploy high quality video processing software that conforms to the serviced-based ethos at their facility and only pay for the time it is in active use.
Similar to the introduction
of IT based systems some 15-years ago, sensible technology decisions need be made in the context of the operational and business benefits to determine which functional components are best placed in the cloud and what should remain firmly anchored on the ground.
