As option +QC, closed captioning presence or absence is detected on SDI streams, with the card or device generating an event action upon CC presence or absence. This event action writes to a log file and can be used for automation actions such as GPO. +QC option is available for the following models.
Advanced HDR Conversion
Mapping between color spaces to preserve artistic intent.
Flexible HDR Solutions to meet the need of your production.
Static Conversion
Static conversion from SDR to HDR or HDR to SDR can be done via a 3D-LUT file. The 3D-LUT file maps the color space, and applies the appropriate EOTF transfer curve. This mapping is applied to all the frames of video regardless of the signal. The Cobalt 9904-UDX-4K is able to insert static LUTS with the +3DLUT-PRO and +3DLUT-4K options. Adding the +3DLUT-BBC option allows the card to come preconfigured with standard LUTs suggested by the BBC for professional broadcast.
Dynamic Conversion
Dynamic conversion takes a static LUT as a base, and allows the user to customize the look and feel of the content in real time. While an up-mapped HDR signal, or down-mapped SDR signal can be technically “legal”, conversion can be optimized for the type of content that is being produced. Cobalt digital products are compatible with both the WonderLook Pro and LiveGrade Pro software that provide full control over the transfer curve and color correction.
Dynamic Intelligent Conversion
Dynamic intelligent conversion goes beyond dynamic conversion alone by allowing an algorithm to automatically adjust the color values based on the incoming video signal. Cobalt uses Technicolor’s suite of HDR conversion tools for this task. The toolset is informed by deep learning from Technicolor’s years of Hollywood colorimetry experience. Video is analyzed frame-by-frame in real time to make adjustments more quickly than a human operator could. As lighting conditions change over the course of a broadcast, the human operator has the ability to focus on other parts of the production.

Unleash your SDR Legacy Content
Select between convenience and control
Manual
In manual mode, the Technicolor ITM SDR to HDR controls give the user the ability to adjust the ranges betwen shadows, midtones, and highlights within the content.
Preset
Preset mode provides 28 preconfigured settings differentiated by brightness and contrast. Users have many options to customize the look and feel of the content, while not having all the controls included in the manual mode.
Additional adjustments include:
- Limiter
- Saturation
- Sharpness
Automatic
In auto mode, the Technicolor algorithm will adjust settings frame-by-frame in real time according to the incoming content. Fine tune adjustments can be made to the unit at the beginning of an event – but after that, the ITM process will make any adjustments due to changing lighting conditions during the event.
Bright spot analysis
Bright spot analysis and management: ability to ensure excessive bright spots are not created when converting from SDR to HDR that might detract from the creative intent of the video.
The ITM algorithm also includes advanced bright spot detection, which will isolate smaller points of light from larger bright spots within the frame. This way, when the light intensity increases from an SDR image to the brighter HDR image, lighting speculars won’t be drowned out by larger areas of light.
Noise Reduction
HDR content can get noisy, especially content shot on film. Technicolor‘s noise reduction is superior to anything currently on the market used for grading.
A static 3D-LUT typically does not have active noise reduction, this is very problematic in low light conditions, upgrading content from older cameras or cameras with small sensors or in cases with camera movement.
A powerful de-noising engine is included, as legacy SDR content will often come with a fair bit of noise. The ability to adjust the noise within the shadows and highlights helps to keep image detail while protecting against banding artifacts.
