With 4K UHD only just turning the corner and with much of the world still in SD is 8K a distraction from the rollout progress of 4K or just natural technological progress? The Broadcast Bridge takes stock of the current fuss around 8K which, like it or not, will be a major talking point at IBC2019.
The human visual system (HVS) sees color using a set of three overlapping filters, which are extremely broad. As a result, the HVS is completely incapable of performing any precise assessment of an observed spectrum.
At one time the only repeatable source of light on Earth was the sun. Later it was found that if bodies were made hot enough, they would radiate light. Any treatment of illumination has to start with the radiation from heated bodies.
Many protocol specifications are used today to reliably transport compressed video over IP networks and the internet. New transport specifications such as RIST with ARQ continue development and testing.
There are a flood of tripods on the market today, and many are not distinguished as video or photo tripods. Especially with very light weight cameras, some models are now combined. It is easy to pick the wrong model for the type of video shooting you will do. Here is a guide to what one needs to know when choosing a tripod/head combination.
LED lights have fundamentally changed the art of light and shadow. Long gone are the days of heavy, hot lights connected with thick cables and noisy generators. Today’s LED lights are compact, battery-operated and cool enough to be easily handled by a single person.
In this new series, it will be seen that color is a complex subject and all the more so for being multidisciplinary. The difficulty with such a large subject is that it is hard to leave things out when they are so fascinating.
The portable video industry began in the mid-1970s using nickel-cadmium batteries with primitive charging circuits. Enough Ni-Cad batteries for one-day’s use often weighed more than the heavy first-generation portable broadcast camera itself. Today, lithium-ion batteries have improved life dramatically. But on the horizon is a new battery technology — solid-state — which promises greater safety, longer life and faster charging.
