For any location production, organization and pre-planning is key. This mantra goes beyond thinking of shoots and equipment placement to actually how your equipment will get from point A to B. This is particularly crucial when selecting batteries for air travel due to the set limit on lithium ion (Li-Ion) batteries. This can be a challenge as many popular cameras and other equipment require a high current draw more than the air travel regulations will currently allow. There are existing and emerging solutions available and, combined with proper planning can ensure that your shoot will run at full power.

Beyond current draw and runtime, capacity is the most important thing to keep in mind when choosing the right battery pack for air travel. Battery capacity represents the maximum amount of energy that can be extracted from the battery under certain specified conditions. The maximum capacity of Li-Ion batteries allowed for air travel is anything less than 99Wh (watt hours). For example, if you own a battery pack with a 98Wh capacity, you are able to travel with as many of them as you would like. This is a major benefit for users who spend a great deal of time on the go with their equipment. Not having to worry about limits and restrictions on batteries makes traveling less of a struggle.

In the past, this would mean simply packing several 98Wh batteries and changing them as needed, but that isn't the case anymore. Battery packs that are acceptable for air travel are now being constructed to specifically address such travel regulations. In order to meet battery capacity requirements, industry-changing designs are being created to make flying with equipment easier. Some of these designs include a two-part battery, which can be separated into two 98Wh pieces for legal transportation without restrictions under IATA, ICAO, and UN regulations. When not travelling, the pieces can be assembled back together; a high capacity, high voltage battery is created, resulting in a wider discharge cycle range and greater runtimes. This battery model allows users to travel with a high-powered Li-Ion safely thanks to a simple yet effective innovation.

Even with the latest technologies, how the battery is packed can also affect performance and a safe arrival. Each battery should be packed individually and separated from its associated device. When packaging up for travel, there should be cushioning material between spare batteries to prevent them from damaging each other. When selecting packaging material for the battery, it should be non-conductive and either be the original retail packaging, a plastic bag, a battery case, or taping the battery terminals

With battery technology advancing, camera operators now have more options for travel while still meeting high draw needs.

Why MADI is Still Relevant
Stephen Brownsill While the original idea for MADI was to cater to a very narrow recording studio application, the standard remains a viable go-to multichannel audio technology. Beginning as a standard in 1991, MADI was first introduced to the world as digital production was beginning to come of age. MADI was put together in 1988 by Solid State Logic, AMS-Neve, Sony (DASH) and Mitsubishi (ProDigi) as a way to transport up to 56 channels of digital audio between large-format audio consoles of the day and digital multi-channel tape machines via 75-Ohm coaxial cables. Both tape-based machines have long since disappeared from the equipment landscape.

Cisco’s latest report, for instance, says that global IP traffic is increasing at 26% a year, and will reach 4.8 zetabytes a year by 2022. The number of connected devices will be three times the world’s population by the same date.

REVIEW Canon UJ111x8_3B UHD Lens
Andy McKenzie Shooting in ultra high definition and high dynamic range has become the preferred option for all television productions with a potentially long commercial life. The hir-ing charge and indeed the outright purchase cost of cameras of this standard are not significantly greater than those of high definition standard dynamic range models. With half the world's news reporters now able to capture UHD video on their mobile phones, why give the production crews anything less?

To Remotely Go - TVFutures
Michael Parsons One of my biggest concerns as an academic responsible for the education of hundreds of students is the ‘appropriateness’ of much of the technology we purchase and implement within the curriculum. The last few years have seen tremendous change in all sorts of technologies, and the broadcast industry is just one sector that has seen some significant leaps in innovation.
