What is the point of having eight motors/propellers when wouldn’t four be more efficient?
The simple answer is yes. On paper, a quadcopter (a craft with four motors and propellers) is more efficient than an octocopter (a craft with eight). The added motors mean more energy sucked out of already limited battery lives, and the larger footprint makes it harder to transport. Despite the drawbacks, there are several reasons why the octocopter is the professional and commercial industry standard.

For its centennial celebration next year, SMPTE is producing a historical documentary on the human stories behind motion-imaging technology.
Veteran remote production specialist Token Creek Mobile Television upgrades “Sioux” truck with the latest HD lenses from Fujinon.
Fujinon’s XA99x8.4 lens combines high-performance imaging, a long zoom reach, and an ultra-wide angle. It also features a patented image stabilization technology for rock-steady performance.
One of the rules of governing the use of drones for filming is that there must be a licensed pilot and another operator in control of the camera. To be strictly legal there is supposed to be a third ‘spotter’. But if you don’t have a specialist videographer to follow you around or perhaps you are busy pursuing a sport how do take video of the activity?
The miniaturization of high-quality portable video began about six years ago with the arrival of video capability in DSLR cameras. However, for those who want to do precision lighting in the field, change has come more slowly.
Knowing which camera to choose for an assignment is important—for those times when you can make this decision. Knowing how to get the best out of the resulting footage you get is necessary when you can’t. Understanding how the technology works can help in both cases.
It may be obvious, but sometimes the obvious needs stating, which is that television pictures can only be assessed by the viewer through the human visual system. It is equally obvious, that moving picture reproduction systems developed without an understanding of human vision will be sub-optimal. That’s where we are at the moment: today’s TV and cinema standards were specified before much of what we know about sight was well understood. With our now expanded and newer understanding, we should apply the science to future television systems.
Broadcasting and telecoms have had a long relationship, one that in recent years has become closer and more symbiotic. But there is one area where the two clash head on: radio spectrum. This is a vital resource for not just television and radio transmission but also the production of entertainment shows and outside broadcasts today, which relies heavily on wireless microphones and cameras, in-ear monitors (IEMs) and mobile communications. Parallel to this is the ever-growing demand from mobile phone companies for frequencies to support video streaming and wireless telephony as well as telephony.
