Colorfront Engine™ Workflow Applications
Processing
Broadcast-Oriented Processing
Broadcast Converter
The Colorfront Engine powers a broadcast conversion tool capable of handling display referred conversions between SDR, HDR PQ, and HDR HLG formats, ensuring seamless color gamut mapping across different output display color spaces. In addition to the primary conversion controls as seen above, there is a full selection of advanced settings that may be applied for further refinement, including Exposure, Color Temperature, Tint, Lift, Gamma, Gain, and Knee controls.
HDR Harmony
HDR Harmony is a specialized tool designed to correct overly bright and saturated HDR content. Leveraging the Colorfront Engine’s perceptual image processing, this tool carefully protects against color artifacts and high- light clipping, resulting in a cleaner displayed image.
HDR Dailies in Express Dailies and On-Set Dailies
Onset and Express Dailies offers the option to utilize the Colorfront Engine (CFE) project type within dailies workflows. This enables dailies operators to apply ACES-compliant IDTs to map all input sources into the internal processing color space, with dedicated tools for adjusting exposure, color temperature, tint, and physically accurate saturation. The project can simultaneously render SDR 709, HLG, and HDR10 deliverables through the perceptual processing engine, enabling effortless production of tandem SDR and HDR dailies.
On-Set Dailies, with its customizable node-based pipe-line, provides even greater flexibility in designing color workflows to deliver any type of output concurrently.
Using the Pipeline Setup wizard on the Node Page, users can create a CFE pipeline for any camera format and combine it with their preferred color correction tools.

Mastering and Re-Mastering in Transkoder
Colorfront's Transkoder offers a comprehensive suite of analysis and processing tools to support single-master workflows. The HDR/SDR Remap tool, combined with a floating-point precision color space conversion tool, allows any display or scene-referred source to be remapped to any target display. Dedicated controls enable adjustments for output brightness, ambient surround compensation, HDR expansion, and colorfulness.
The remap process can be separated into an input transformation (reverse tonemap) and an output transform, allowing custom grading tools to be inserted in between. This flexible pipeline is ideal for remastering workflows, enabling colorists to use creative grading tools to fine-tune shots where automatic mapping may not achieve the desired aesthetic.
Transkoder's integrated Second-Head Analyzer can be configured to operate in any color space, allowing the mastering operator to inspect brightness and gamut levels at both the input and output stages. With the continued advancement of immersive and high dynamic range cinema display technology, the ability to efficiently master for each specific display while preserving the artistic vision is essential.

Re-Mastering
Dolby Vision™ Re-Mastering in Transkoder
SDR to Dolby Vision™
Dolby Vision offers a premium format that seamlessly bridges HDR and SDR consumer display technologies. While Colorfront fully supports traditional Dolby Vision mastering tools, we have also developed advanced tools for converting final graded SDR content to Dolby Vision.
The SDR-to-DolbyVision tool utilizes the Colorfront Engine to convert SDR content to Dolby Vision HDR, generating unique Dolby Vision metadata to ensure the Dolby-derived SDR output visually matches the original SDR content. This innovative round-tripping method enables a unified, streamlined, single-source workflow for mastering and distribution.
The SDR to Dolby Vision feature is also available in the AJA ColorBox. By previewing the SDR to Dolby Vision conversion within ColorBox, whether on set, in editorial, or in a color suite, you can be confident that your final Dolby Vision deliverables in Colorfront Transkoder will accurately reflect the look established during production and post.

DCI to Dolby Vision™
Building on the capabilities of the SDR-to-DolbyVision node, the DCI-to DolbyVision tool in Transkoder enables the transformation of XYZ cinema masters, intended for 48-nit theatrical presentation into Dolby Vision HDR for home video.
This tool preserves the original creative intent while generating a Dolby Vision master complete with corresponding metadata.

HDR Rolloff
Transkoder's HDR Rolloff tool allows you to easily manage highlight rolloff in HDR content, with controls for adjusting peak luminance and the softness of the rolloff curve. Performed within the perceptual color engine, this process carefully preserves the original creative intent. This feature is especially valuable for producing highlight-managed deliverables suited to emerging HDR exhibition technologies.
