The Cloud and the Evolution of Post-Production
By Stephen Streater, CEO, Forbidden Technologies
For many years, the pace of change in mass market IT has dwarfed that of
broadcast technology. For example, consumer camera phone resolution has
increased over the last ten years by 30,000%. In comparison, broadcast
resolution has barely tripled. With the development costs of consumer cameras
amortised over hundreds of millions of units, there is no way that the broadcast
industry can compete on the pace of progress. Nor should it try to.
But in post production, large parts of the existing IT infrastructures are exactly
those, which benefit most from the latest revolutions in mass market IT.
Computer processing power, storage, and Internet access, all fuelled by massmarket consumer demand, are exactly the features offered by cloud solutions.
As new technology enables more and more of the broadcast workflow to move
into the cloud, little more than a modest computer and an Internet connection is
needed to be able to create there. Processor speed, file size, and security, long
regarded as significant barriers to cloud-based workflows, are no longer issues.
Now, instead of transitioning to newer and newer generations of broadcast
hardware, we’re moving from one IT solution to another. Because of this, the
cost savings are significant.
What Makes the Cloud Suited for Post-Production?
Just as large-scale suppliers provide electricity more economically, processing
and storage requirements can often be met more economically by cloud
services. And just as electricity comes to us directly via connection to a power
grid, data comes directly to a computer via connection to the Internet. In
addition, cloud services from different providers can easily interact through
automated interfaces, providing a highly flexible way of using solutions and addons from different suppliers throughout a given workflow.
However, when it comes to video post-production, not just any cloud service will
do. Generic cloud-computing providers, such as Amazon Web Services, are
built for IT and consumer data rather than the voluminous data and throughput
performance requirements associated with broadcast video. The requirements
for editing video are formidable, with huge amounts of data and the need for
real-time response. The process of rendering effects and transitions in a generic
cloud environment are expensive since these services charge according to CPU
power and time used, and the unresponsiveness would be frustrating for users
accustomed to dedicated desktop solutions. When all of this is taken into
account, building a broadcast post-production operation on a generic cloud
infrastructure simply doesn't meet broadcast standards for performance, cost, or
reliability.
Dedicated platforms optimised for broadcast applications not only offer lower
cost and far greater performance, but also increased control over where the
data is stored for legal, regulatory, and personal preference requirements. A
cloud service lives or dies by its QoS. Over time, competition will only serve to
eliminate any remaining reliability issues.
Capacity and Efficiency
The capacity of the Internet and cloud services is essentially unlimited, with
supply expanding to meet demand. Storage and Internet speed nearly double
every year, and new solutions from the world of mobile are improving power
consumption within the cloud. With 10 Gb/s intranet backbones coming into
service now, throughput will continue to improve drastically.
The greatest efficiencies come from leveraging client computing to undertake as
much of the processing workload as possible. Though it might sound odd
coming from a provider of cloud solutions, such a scenario provides immediate
scalability, reduces latency to negligible levels, cuts costs and allows access
with even the most modest of hardware set-ups. In fact, combining client
processing with a dedicated cloud model allows us to give our FORscene
customers unrivalled value for their money.
Better Picture Quality
The cloud is well suited to the post-production convention of working with
proxies, a method that, at least for the foreseeable future, will be more efficient
than working with high-resolution content. Proxies will continue to improve in
both quality and resolution, with, for example, higher resolutions provided for
fine-cut editing than for logging. FORscene has supported SD proxies for six
years (though productions tend to use lower resolution to save cost).
Conforming from original HD sources ensures minimal generation loss on the
final output.
Many are already making 4K home videos in the cloud aided largely by the fact
that connection speeds have doubled every year while storage costs have
halved. As these factors continue to improve, the cloud will look more and more
attractive as an alternative in a wide range of post-production workflows.
Technology has made it easy to do post-production in the cloud. Now the focus
is on improving and perfecting reliability, responsiveness, interface design,
price, and integration to other applications.
Security
Data security is an issue with any IT-based system. The risks of losing data can
be mitigated by keeping multiple copies of data in multiple sites — something
that is much easier for a cloud provider to do well than for an individual
broadcaster. In the case of FORscene, only the proxies are uploaded into the
cloud and the original full resolution files remain on the users local hard drives.
As long as users have and use a back-up strategy, the security of their video
assets can be assured.
Workflows and Adoption
The prospect of change takes people out of their comfort zones and therefore
happens much more slowly than changes in the underlying technologies. This is
especially true of broadcast and creative workflows that each come with their
own unique tricks, work-arounds, and emotional attachments. When FORscene
launched a decade ago, people were understandably cautious. However, now
people use the cloud in their everyday lives, sometimes without even realising
it, and they are more open to adopting it professionally. An increasingly
technology-literate young workforce — already fluent with cloud technologies in
their personal lives — will accelerate cloud acceptance and adoption.
Beyond Post-Production
The future of cloud-based broadcast infrastructures goes well beyond editing.
Maintaining different equipment for the many different components of a postproduction workflow becomes less important as the cloud offer improves.
Already, the cloud can provide fully featured solutions for ingest, graphics
creation, post-production, publishing, hosting, search, distribution, and
advertising.
Producers of genres such as near-live sports for Internet and mobile distribution
can already do all their post-production in the cloud. Dedicated cloud postproduction platforms such as FORscene can take in multiple live HD video
feeds (at one point during testing for the Summer Games, there were 200!),
incorporate graphics from various cloud creation systems, perform all the
editing and finishing, conform at full resolution, and hand over to another cloud
solution for mass distribution. Clients can mix and match. In fact, Microsoft
Azure is designed for just such a scenario. In the not-to-distant-future
broadcasters will have an even wider variety of options to choose from that will
work flawlessly together to create completely customized, end-to-end cloud
solutions.
Conclusion
The relentless advances in technology are transforming post-production.
Traditional desktop IT solutions are being replaced with more cost-efficient and
productive cloud-based solutions while, at the same time, technological change
is transforming the distribution and consumption end of the business. Suppliers
of traditional post tools and their users would do well to embrace these changes
rather than refute them.
