With HDR/WCG content production being the demand of present times, the video industry is turning towards 4K HDR/WCG content creation with most new video trucks and video facilities incorporating these technologies.
However, effective production of HDR/WCG content requires the right tools and enhanced measurement techniques. For instance, cinematography setup now holds more importance than it used to be in the past given the risk of creating issues which can’t be fixed in post-production (e.g. noise in dark areas).
Innovative techniques are also required to monitor the various camera log formats and conversion to perceptual quantizer (PQ) or hybrid-log gamma (HLG). Besides, High Frame Rate (HFR) increase may also have added advantage for high motion content development like live cricket or other sports telecasts.
Recent consumer research has revealed that such features can result in more realistic experience and have been received very positively in the marketplace. This has led most of the test and measurement manufacturers create and promote related technologies and equipment.
Cost effective and free upgradation to HDR
Most of the instrument suppliers are providing their existing customers with a free upgrade software for compatible devices. For older devices or non-compatible devices there are exchange policies at very minimal cost implications. Customers with a valid existing software option key license can upgrade their instruments free-of-charge with new firmware that can be downloaded from manufacturer websites online.
Trending Suppliers of HDR Wave Monitors
The market trends have kept the research and development (R&D) teams of most of the major players in wave monitor industry on toes. But here we are featuring only few major players who are already in the market with such technology.
Official press release by Tektronix Inc. states that the 4K HDR/WCG enhancements span the full range of Tektronix waveform monitors as well as the PRISM hybrid SDI/IP media analysis platform. Tektronix waveform monitors and rasterizers provide flexible options and field installable upgrades to monitor a diverse variety of video and audio formats.
Support for video formats includes 4K/UHDTV1 (4096×2160 and 3840×2160), 3G-SDI, Dual Link, HD-SDI and composite analog. Support for audio formats includes Dolby E, Dolby Digital Plus, Dolby Digital, AES/EBU, embedded audio and analog audio.
Omnitek with its ULTRA XR series promises features like True 4K flat frequency response Waveform Analysis, Vectorscope and Histograms (ADV_COL option).This also includes High Dynamic Range (HDR) inputs: ST2084 / PQ and Hybrid Log Gamma (HDR option) with Wide Colour Gamut RGB: ITU-R BT.2020. It can support comprehensive standards up to quad 3G, dual 6G and 12G-SDI along with supporting 2 sample interleave, square division formats, comprehensive ancillary and audio analysis.
The LV5490 and the LV5480 are two waveform monitors manufactured by Leader that can support 4K video signals. They can display up to four channels of 3G-SDI input signals simultaneously. There are four dedicated input connectors with cable length measurement capability and four additional connectors can be configured as inputs or outputs, making a total of eight inputs, if needed. The built-in 9-inch LCD monitor is Full HD (1920 x 1080) with wide viewing angle and high color reproduction.
Upgrade Cost vs Benefits
Looking into the benefits and requirements of HDR Wave monitors the cost of upgrades is not much keeping in mind the end product- the video content getting more and more costly with today’s ever evolving industry demands. These new technologies would surely be embraced by the industry but its pace of adoption have to observed in coming days.
