What are the challenges of AoIP
|
 |
At the setup of a recent Outside Broadcast (OB), I was privy to an attempt to pass a signal across two independent Audio over IP (AoIP) enabled trucks. In an SDI world, this bridge would have been as simple as coupling two BNC cables together, but here the engineers quipped about the additional and sometimes challenging processes of connecting one truck's IP router to the other's. What range, what subnet, what protocol? And so, I was introduced first-hand to some of the practicalities of transitioning from SDI to AoIP within a live production environment.

How to illuminate a better shot
|
 |
LED (Light Emitting Diode) technology built for the general lighting market is designed to meet very different criteria than the critical lighting requirements for image capture. While LEDs may be a suitable lighting option for some photography and videography, critical applications, such as feature film, production requires users to understand the limitations, capabilities and advantages of the many types of LED technologies and fixtures available on the market today.

When it comes to filming from above, drones have dominated in recent years. But restrictions on where and when they can be used means there is still a demand for traditional style jibs.

Consumer of the shelf technology is coming
|
 |
I had the privilege last week of sitting in a strategy session of the Digital Production Partnership where we were concerned with predicting the future. As Niels Bohr once famously said, "Predictions are really hard - especially when predicting the future". One of the attendees made a comment about camera technology and I instantly thought about the latest greatest and most expensive High Dynamic Range, Wide Colour Gamut, Low Noise, High Sensitivity wonder-device that are being talked about at the technological bleeding edge of the industry. |

The Benefits of LED Lighting in Broadcast
|
 |
The humble LED studio light has come a long way since its introduction. In the early days adoption was low, while scepticism that the quality and functionality of LEDs could rival traditional tungsten lighting was high. There has been a period of adjustment, challenges (particularly around light quality and manufacturing) overcome and the broadcast, media and entertainment industry has gradually grown more accepting of the technology and its benefits.

Not all power is created equal
|
 |
Battery companies are quickly coming to realize that as new technologies continue to emerge, power solutions cannot be a one-size-fits-all commodity. There is no single battery for every situation, but instead a myriad of choices to accommodate even the most complex requirements. Below are five common videographer or photographer scenarios with the corresponding power option that will best fit the situations' needs |

The Transistion in Audio Monitoring
|
 |
As signal chains have become increasingly complex, the challenges involved in managing and monitoring these paths have multiplied exponentially. Over the past few decades, we've migrated from handling a single channel of content using composite video and analog audio pairs, to elaborate multi-channel facilities routing HD video with embedded audio over SDI or in many cases discrete AES pairs. These audio signals are often a mix of 5.1 and stereo programs and in many cases encoded to or decoded from Dolby at some point in the chain.

Assets in the air
|
 |
People everywhere are talking about "the cloud", as if it is somehow something (1) new and (2) intrinsically exciting. It really is neither of those things. In the IT world, software as a service (SaaS) has been around since the 1960's when organisations bought the use of mainframe software on a time-sharing basis. |

The future of post production
|
 |
Love it or hate it, 2016 will certainly be a year to remember, for many reasons.
In the world of post-production, we've seen high dynamic range become incorporated into UK studio pipelines for the very first time. We watched Ang Lee demonstrate exactly what you can do by shooting at 120 frames per second in combination with stereo 3D. We've even become stunned spectators as film steadily makes a comeback as a creative medium, and VR goes from tinkerer specific to becoming a fully-fledged consumer technology to buy.

In today's fast-paced world of video production, the importance of a well-organized, responsive media asset management system cannot be overstated. After all, time is money, and the more quickly people can find and retrieve the exact content they need, the more quickly they can complete their video projects ¦ and capitalize on the content.

5 top tips to getting the grade you want
|
 |
Generally speaking, a grade session can be broken down into two distinct parts - managing the people involved and managing the grade itself. As colourists, we know that unless both of these criteria are satisfied, it is likely that the client will walk away from the project unhappy and not return to us with the next job. |

Sully - Grading a miracle
|
 |
We all know the story. On 15 January 2009 an Airbus A320 took off from LaGuardia airport in New York, heading for Charlotte. Just a couple of minutes later the plane flew through a flock of Canada geese and blew out both engines. Knowing the risk of crashing into heavily populated areas, Captain Chesley Sullenberger - Sully - aimed for the only long flat surface he could see: the Hudson River. |

6 Misapprehensions of MAM
|
 |
Implementing a media management system is considered to be a risky business. The perceived complexity, upheaval and perception of failure can be so daunting that the risk may seem to outweigh the reward. But, like so many business technologies, MAM have been transformed in recent years and it's time to debunk some common MAM myths. |

Challenges for MAM with varying production types
|
 |
Many media asset management platforms are designed to handle the immense number of assets needed for today's fast-moving, content-heavy productions. Since every production is unique, each has its own set of asset management requirements and workflow needs. While the unique workflows vary, a common necessity for an easy-to-use interface with the ability to efficiently organize and manage large amounts of content is required, regardless of the type of production you are working on. |

MAM needs to adapt or die
|
 |
The media landscape has shifted dramatically over recent years. Content providers are under increasing pressure to deliver compelling content to multiple platforms. Also, the production and distribution of video is no longer limited to traditional broadcasters, which face rising competition from a range of media providers. We are also seeing a massive increase in video being produced to broadcast quality by companies using it for other purposes, such as marketing, site surveys, internal communications, and a whole host of other applications. |

Mixing console displays - central to usability
|
 |
Since the introduction of assignable controls on mixing consoles, it has been essential to provide sound engineers with a clear picture of what the function and status is of each fader and other associated controls. Consoles can have over 100 faders. To allow the sound operator to keep track of the function of each panel and its current settings, clear, compact displays are needed. |

Social streaming and broadcast
|
 |
We are witnessing a growing trend from broadcasters looking to complement TV content with social streaming. When done well, it can really help increase consumer engagement on a huge scale and we have seen some great examples of it over recent months. At the recent Kit Plus Show, I talked about the marriage between broadcast and social streaming, what works, and what some of our customers have been doing in this arena. |

Health and Safety gone mad
|
 |
The first true broadcast television service started 80 years ago, on 2 November, 1936. Its home, famously, was Alexandra Palace, a vast and really rather run-down building on top of Muswell Hill in north London. Originally opened in 1873, and re-opened in 1875 after a catastrophic fire, it was built primarily as an entertainment venue. Indeed, it was built as "a palace of the people", a usage of that expression a century or more before most of us associate it. |

80 years of broadcast and how far we have come
|
 |
The BBC delivered its first continual public broadcast 80 years ago, that included coverage of the BBC Television Orchestra and famous musical comedy star Adle Dixon. This was a world first heralding the beginning of continuous broadcasting in the UK and kicking off the broadcast industry's constant search for new ways to improve the accessibility and quality of television content. |

Diversify or Die
|
 |
This headline of this article is a simple fact, diversify or die! It is necessary for survival as well as interest of mind to do this within business. "If a farmer can no longer produce crops because no-one wants them he must diversify or die." Caravans, glamping, corporate days in the country with hunting, fishing and shooting; these are just some of the changes that Britain's' farmers have made or they have gone out of business. |

You need more damn pixels
|
 |
There has obviously been a lot of chatter in recent years about 4K, but is it enough?
8K and beyond is where the excitement lies, but not in the way you might think. 8K and beyond for broadcast, both of which are easily achievable in a software-only, IP environment, may seem a bridge too far for most at the moment, and they're probably right¦for now. |

The world is not flat
|
 |
The world is all around us. We have a lot of cues that make us aware of how we fit into a 3D space. Many of these cues, senses and reactions are survival instincts. For example, the ability to hear someone walk up behind us, to see movement in our peripheral vision, a sense of how we are oriented when we move our bodies or swivel our head. All of this creates an overwhelming amount of data that we seamlessly interpret as we go around our day getting our morning coffee, driving, walking through crowds, diving into pools, and everything that we as people do in our lives. |

Radio cameras bring a live broadcast to life
|
 |
Radio cameras bring a live broadcast to life - especially news, sports and studio shows - by their ability to roam around and move in closer to a subject. They capture a more natural spectator's view than a camera that is fixed at one point, and usually get the most intimate shots and the most exciting angles in a production. Today they are indispensable for covering large outdoor events - but if they have a weakness, it is probably the antenna. |

The importance of a low noise floor
|
 |
The Noise Floor of a piece of T&M equipment is the inherent noise (or intrinsic jitter) introduced by the equipment itself. The level of inherent noise affects the accuracy and repeatability of jitter measurements that can be made, especially when measuring low levels of jitter. With the permitted 100KHz jitter on a 12G-SDI signal being only 0.3UI, it is important to establish the total level of jitter in the signal path to ensure that it does not exceed this limit and cause data errors. |
