Colorfront has announced at NAB that its Transkoder product has been certified by Dolby Laboratories for Dolby Vision HDR content mastering, as well as being approved by Amazon/Samsung for HDR10+ Dynamic Tone Mapping and metadata mastering. 


Colorfront’s Transkoder was certified by Dolby Laboratories for the creation of Dolby Atmos Digital Cinema Packages (DCPs) in 2015 and it has now been certified for Dolby Vision Mastering and Mezzanine packaging and playback of UHD, HDR and Wide Color Gamut content. 

Transkoder supports Dolby Vision’s 10,000 nits peak brightness target, 12-bit color depth and Rec.2020 color space standards. Transkoder can preview mapping content with metadata to a reference display, or drive an external Dolby Content Mapping Unit (CMU),  calculate the required light level statistics, and render Dolby UHD IMF mezzanine format with per-frame metadata. 


Colorfront also used the show to launch its Colorfront QC Player, a system enabling post and studio facilities to perform quality control tasks on UHD and HDR content. It runs on Supermicro and HP Z840 workstations with AJA’s Kona 4 I/O card supporting realtime output up to 4K at 60fps. QC Player’s transport controls include support for external panels from BUF and Tangent.


The QC Player supports all the major RAW UHD HDR formats including Alexa ARRIRAW – both MXF-wrapped and .ARI files; Panasonic VariCam 4K VRAW and Panasonic AVC-Intra; Sony F55 and F65 RAW, XAVC and X-OCN; Blackmagic DNG; Canon RAW; RED R3D; Apple ProRes; plus DPX and TIF sequences from scanned sources. It also supports playback of JPEG 2000 content, including DCPs (2D and stereo, encrypted, with subtitles) and IMF packages, such as lossless/high-bit-rate UHD Dolby Vision mezzanine masters with dynamic metadata and Dolby CMU control.


For UHD HDR image analysis tasks, QC Player includes waveform, vectorscope, histogram, split-screen, colour gamut and light-level metering tools. It features framing guide overlays for title/text/logos/graphics safe areas, plus image reframing and burn-in/watermarking tools. QC Player also comes with audio tools supporting embedded audio, WAV files and up to 24-channel audio output.


It’s set to ship in Q2 2017 and is priced at $10,000, with an annual rental option of $5,000, both including support and updates.


Colorfront has also teamed with AJA to make the FS-HDR HDR converter.
