Tektronix has debuted a set of production tools to help content creators minimise and manage the complexity of the 4K collection of technologies at their source – the camera.

4K 31 aug 2017To help manage 4K resolution, wide colour gamut (WCG) and high dynamic range (HDR), Tektronix has added a 4K/WCG/HDR toolset to its PRISM production solution, specifically designed to address multi-format and multi-standard challenges.

The challenges are myriad: for instance, in live environments, there is often a mix of HDR and standard dynamic range cameras used. When using traditional waveform monitors to balance these cameras, the different trace levels for the same luminance levels force operators into guess work as they try to balance the cameras.

Also, in studio or episodic production environments, there is a high cost associated with scene setup and luminance levels, so camera operators and directors of photography need quick and consistent ways to set lighting using displays that provide measurements and levels that have a direct correlation to the relative light levels, rather than the percentage scales available in traditional waveform displays.

In addition, matching colours and skin tones across different colour spaces (BT2020 and BT709) is challenging when producing content in multiple formats, which means operators need familiar displays (such as BT709 Vector display) that enable them to make these checks quickly and accurately.

“Multiple and still-evolving 4K, WCG and HDR standards and formats put content creators in the position of having to deal with an array of confusing and complex requirements almost daily. And when errors happen, they can end up being costly and time consuming,” said Charlie Dunn, GM, Video Product Line, Tektronix. “With our new comprehensive monitoring solution based on the PRISM platform, we are helping our customers confidently create high quality content with the latest technologies, giving them a competitive advantage and lowering costs and reducing risk.”

The tool set includes a Tektronix-patented Stop Waveform Display that allows operators to adjust camera exposure in a consistent manner without having to worry about the optical to electric transfer function (OETF) of a camera. It also allows cinematographers shooting episodic dramas to quickly create scene or subject lighting.

Also, a vector display with a 3D look-up table (LUT) that allows the familiar BT.709 vector can be used to evaluate skin tones, match colours to familiar reference marks and determine the degree of colour gamut compatibility for BT.709 conversion.

Also, a combination of full, quad or vertical display modes gives operators extensive flexibility to view application displays optimally for their needs.
