The increasing use of High Dynamic Range (HDR) and wide color gamut (WCG) acquisition has not only improved signal quality on live sports and other telecasts, it has also helped the bottom line of those that make professional 4K lenses. Both visual and lab tests have shown that the superior quality of a 4K UHD lens helps even HD cameras look better, and that’s helping lens sales in a Broadcast market that—with the emergence of handheld, fixed lens (with 1/3 and ¼-inch sensors) camera models now used extensively in newsgathering—gets harder every day.
The NAB show has been cancelled. This announcement was made by NAB president, Gordon H. Smith.
The world’s oldest surviving motion picture, often called Roundhay Garden Scene, does not include any camera movement. It’d be tricky to imagine anything approaching a move, since the scene, which was shot in 1888 by Louis Aime Augustin Le Prince on a camera of his own invention, is just a hair over two seconds in length. Better known early movies include the 1895 work of Auguste and Louis Lumière, whose fifty-second short L’arrivée d’un train en gare de La Ciotat (“The Arrival of a Train at La Ciotat Station”) famously had people ducking for cover as the train rolls into the station.
Cold weather videography can be challenging and is plagued with danger for the production gear. Driving rain and snow can ruin unprotected gear, while extreme cold can shorten battery life and threaten a range of devices in the production chain. Here are some ways to be prepared for winter weather shoots.
Within broadcast there has always been a quest for higher and higher resolution with improvements in wider color fidelity. The quest has always been to deliver what we see to the audience, often this is limited by technology or cost of production, but today there is the possibility to increase the resolution to 4K/UHD with High Dynamic Range (HDR) and Wide Color Gamut (WCG) that can convey that window on the world to the consumer.
Systems intended to convey color images all need to have a defined white point for practical reasons. The white point is where the luminance axis passes through the plane of the chromaticity diagram on its way from black to white.
I often shoot video of bands in front of live audiences. It never ceases to amaze me how many performers ignore the rules of good microphone technique. They literally “eat the mic,” creating not only terrible sound quality but making it impossible to get decent images without the mic blocking their face.
Development of new technology and moving to the newly available 5GHz spectrum continue to expand the creative and technical possibilities for audio across live performance and broadcast productions.
