Live Video Encoding and Processing with NDI 6: Embracing 10-bit HDR Workflows

The introduction of NDI 6 represents an evolution in IP-based video transport, tailored to support intricate and superior-quality video productions.

With its robust capabilities like 10-bit color and High Dynamic Range (HDR) support, NDI 6 is particularly suited for the remote cloud production of premium content, including sports and live broadcasts.

Why 10-bit Color is Essential

Transitioning from 8-bit to 10-bit color depth is more than just an increase in numbers—it’s a substantial upgrade in broadcast quality.

While 8-bit offers 16.7 million colors, 10-bit color depth expands this to over 1 billion colors, reducing the risk of color banding and preserving the integrity of the video throughout the production chain.

Benefits of NDI 6 10-bit environment:

  • Visually Lossless Quality: NDI 6 offers flexible IP video connectivity while supporting the bit depth of traditional SDI standards, merging the reliability of broadcast standards with the flexibility of modern IP-based workflows.
  • Color Precision: Streams are rendered with maximum accuracy, representing colors and intricate image elements like gradients, shading, and fine details with utmost precision.
  • Alpha Channel Support: The 10+ bit color depth extends to the alpha channel, enhancing transparency control. This allows for more nuanced and accurate compositing of visual elements, vital for complex video productions.
  • Expanded Creative Possibilities: NDI 6 unlocks professional-grade video editing capabilities in every frame, catering to both high-end productions and individual content creators aiming to produce the next viral video or homemade vlog.

The 10+ bit depth is essential for professional broadcast settings where color precision and detail are critical.

The Significance of HDR in Broadcasting

HDR significantly enhances the viewer experience by providing greater contrast and a wider range of colors, making the video content more vibrant and realistic.

Benefits of HDR in Broadcasting:

  • Higher Contrast and Expanded Brightness: NDI 6 introduces higher contrast levels and expanded brightness headroom, enhancing detail in spectral highlights and providing stunning visual contrast.
  • Wide Color Gamut: With support for up to 16 bits per color channel, it enables over a billion color combinations, allowing for a more precise and extensive range of colors essential for premium content production.
  • Minimal Color Banding: The technology ensures ultra-precise color production, facilitating smooth transitions and seamless gradients, minimizing color banding. This feature is vital in maintaining quality where subtle gradations in color and tone are decisive.
  • Broad Compatibility: NDI 6 supports PQ and HLG formats, ensuring accurate streaming to a broad range of HDR and non-HDR devices. This compatibility helps streamline workflows and ensures viewers receive the best possible quality across various platforms.

Adopting 10-bit color in HDR workflows, supported by NDI 6, is crucial for achieving these superior visuals, ensuring broadcasters have the tools necessary for producing immersive and engaging content.

Live Remote Production with NDI 6 in the Cloud

NDI has emerged as the de facto standard mezzanine format for live production in the cloud. With its low complexity and low latency, it’s an ideal IP format for virtualized environments

Here’s how NDI leverages the cloud to transform live video production:

  • Reduced Production Costs: Cloud-based production lowers costs by allowing users to access professional production tools on a pay-as-you-go basis, making high-quality content creation more affordable. This enables individuals and small teams to use advanced tools typically reserved for major studios.
  • Lower Carbon Footprint: With cloud infrastructure, production teams can collaborate from anywhere, reducing travel requirements and the carbon footprint associated with traditional on-site production.
  • Broadcast Quality and HDR: NDI 6 ensures full broadcast quality in the cloud, including HDR support for superior visuals. This feature, combined with its low latency, makes it suitable for live broadcasts and sports events that require high fidelity.

NDI 6’s comprehensive broadcast capabilities empower production teams to deliver professional-quality content to global audiences while benefiting from reduced costs, increased flexibility, and a smaller environmental impact.

Comprimato and NDI: A Partnership from the Start

Since the initial announcement of NDI 6, Comprimato has been a key partner, leveraging the technology to enhance our video encoding and processing solutions.

Our early access during the beta phase allowed us to integrate and innovate with HDR workflows effectively, ensuring our readiness to support the latest standards as soon as NDI 6 was launched.

Leveraging 10-bit Colors with NDI 6

With the integration of NDI 6 into our software, Comprimato now supports 10-bit color HDR workflows. This advancement is a further step for cloud-based remote production, where maintaining the highest quality of color and detail across different locations is imperative.
