Swiss-based developer of solutions for post production Marquise Technologies has announced its partnership with Canon, providing studios, broadcasters and post productions companies a unique solution for their HDR mastering workflows.
The continuity of information about the image between the colour grading and the mastering phase is important and becomes crucial when the content is in HDR. The full chain, from the mastering solution to the mastering environment, including the mastering display, must work in sync to avoid human mistakes as much as possible.
By providing full control of the mastering display in its MIST mastering system and ICE reference player, Marquise Technologies offers a unique feature that enhances HDR mastering and quality control.
The characterisation of the mastering display based on the SMPTE ST-2086 standard is a key element when working in PQ (ST-2084) and Dolby Vision. Once these parameters are set in MIST or ICE, they are sent to the Canon monitor to configure the display in the right mode by using a remote control protocol: colour space, EOTF, luminance levels are automatically set to the correct value.
At NAB, the control of the mastering display is being demonstrated using the Canon DP-V2420 4K reference display. Canon’s flagship 24 inch model satisfies the high luminance performance required for HDR workflows. Sharing many of the outstanding features of the DP-V2410 4K reference display, the DP-V2420 adds additional versatility and functionality. It qualifies as a Dolby Vision mastering monitor (supporting the ST-2084 gamma curve) as well as the proposed HLG (Hybrid Log-Gamma) broadcast HDR standards. This is today the only available reference monitor that provides a remote control protocol.
At NAB, HDR demonstrations using the Canon DP-V2420 will include: HDR mastering in Dolby Vision, HDR10 and HLG, and creation of the deliverables in MP4 HEVC & H264 with ST2094-xx metadata as well as IMF Studio Profile and IMF-TV.
