Seattle software developer SpectraCal, Inc. has partnered with Quantum Data, global leader in video test pattern generators and analyzers, to provide test pattern support for HDR-10 High Dynamic Range (HDR) displays.
“High Dynamic Range is the most important development in video since the high definition TV,” said SpectraCal’s Chief Color Scientist Stacey Spears. “With the rapid growth of HDR, objective measurements of video performance have never been more crucial,” Spears said.
Developers from SpectraCal and Quantum Data worked closely together to ensure that Quantum Data’s hardware and SpectraCal’s software would jointly support emerging standards in HDR.
“HDR-10 requires new signaling mechanisms to support HDR-10 metadata over HDMI,” remarked John Burt, Senior Applications Engineer, who led the HDR-10 development efforts for Quantum Data.
“The speed with which Quantum Data was able to accomplish the HDR solution, especially given the complex signaling requirements of HDR-10, underscores the strength of Quantum Data’s design,” said Spears.
Quantum Data’s VP of Sales and Marketing, Chuck Evans commenting on SpectraCal’s important role in the industry, remarked, “SpectraCal has been leading the way in video calibration software since the company was founded. Their effort in bringing HDR-10 support to the market is just the latest example of their leadership, and Quantum Data is delighted to have partnered with SpectraCal. ”
Support for HDR-10 patterns is available in Version 5.6.1 of SpectraCal’s CalMAN software, the most widely used video calibration software in the world.
“You can use a Quantum Data 780 to send HDR-10 metadata from CalMAN 5.6.1 today,” said Spears.
I get the concern about DCIP3/BT2020, but the key is being able to adjust gamut with HDR activated, up until now people have not been able to do both together.
Be sure to ask Chad how any firmware updates that will modify the color balance will affect your professional calibration. I would think you'll be calling him back often.
FWIW- absent the special expensive test equipment and training, I did my calibration based on matching colors from the 2K Blu Ray same scene to that displayed on the UHD 4K. My system uses to HDMI feeds to the projector so switching back and forth is fast.
As to HDR content, some "experts" claim that no projector or present TV except possibly the OLED has enough light output to properly reproduce the HDR range.
I dont use display apps, so I will stay away from them .
