The demand for high-resolution video continues to grow—think 4K, 8K, and immersive VR experiences. With streaming audiences expecting better quality and faster load times, content providers face a major challenge: balancing video quality with bandwidth efficiency. Enter H.266, also known as Versatile Video Coding (VVC)—a revolutionary codec designed to power the future of video streaming.
In this blog, we’ll break down what H.266 is, how it compares to previous codecs, and why it matters for OTT platforms like Vodlix.
What Is H.266 / VVC?
H.266/VVC is a next-generation video compression standard developed by the Joint Video Experts Team (JVET), a collaboration between ITU-T and ISO/IEC. Officially released in 2020, this codec is the successor to H.265/HEVC and is designed to handle modern video demands, such as:
4K & 8K resolution
360-degree video
Virtual Reality (VR) & Augmented Reality (AR)
HDR (High Dynamic Range)
But what sets it apart? Efficiency. H.266 promises around 50% better compression than its predecessor without compromising visual quality.
Why Is Video Compression So Important?
Streaming video is bandwidth-intensive. The larger the file, the more data users must download—and the higher the cost for content providers. Efficient video compression like that offered by H.266 enables:
Support for ultra-high-definition content without buffering
For OTT platforms, these advantages translate into better viewer satisfaction and lower operational overhead.
Key Benefits of H.266/VVC
50% More Efficient Than H.265
H.266 delivers the same visual quality as H.265 at half the bitrate, making it ideal for 4K and 8K content delivery.
Versatility Across Devices
True to its name, Versatile Video Coding supports a wide range of devices and use cases—from smartphones to smart TVs and VR headsets.
Future-Proof Technology
With support for advanced features like adaptive streaming, screen content coding, and multi-view video, H.266 is built for the next decade of digital content.
Better ROI for OTT Providers
Reduced bandwidth and storage costs directly contribute to improved margins and user experience—critical KPIs for OTT businesses.

If you’re looking to build or upgrade your OTT platform with the most advanced video tech, Vodlix has you covered. Stay ahead of the curve—because the future of streaming demands it.
H.266, also known as VVC (Versatile Video Coding), is a modern video codec standard finalized in 2020. Developed by JVET (Joint Video Experts Team), it succeeds H.265/HEVC and aims to deliver significantly better compression—up to ~50% bitrate savings while preserving video quality.
2. How much more efficient is H.266 compared to H.265 and older codecs?
H.266 offers roughly 50% bitrate reduction compared to H.265/HEVC for the same perceptual video quality. Compared to H.264, savings are even larger—often in the order of ~75%.
3. What kinds of video and use cases benefit most from H.266 / VVC?
Use cases include ultra high resolution video (4K, 8K), 360°/omnidirectional video, VR/AR content, HDR video, live streaming, and screen content (e.g. graphics / gaming). It’s especially useful where bandwidth/storage cost or network constraints are a concern.
4. What are some of the technical features that enable H.266’s improved performance?
Features include more flexible block partitioning (e.g. coding tree units and nested multi-type tree splits), improved intra- and inter-frame prediction modes, loop filtering enhancements (Deblocking, SAO, ALF, etc.), support for higher bit depths and resolutions, and support for screen content, HDR, variable frame rates.
5. Is H.266 widely supported by devices and platforms yet?
Device support is still in early phases. While software decoders and encoders exist, hardware support (in TVs, phones, set-top boxes) is more limited. Adoption will increase over time as newer devices incorporate VVC decoders.
6. What are some drawbacks or challenges of using H.266 / VVC?
Some of the trade-offs include higher encoding/decoding complexity (more computationally intensive), potential licensing / royalty costs due to patent pools, longer encoding times, and limited compatibility with older or lower-power devices.
7. How does H.266 / VVC compare to AV1 or other modern codecs?
H.266 generally offers higher bit-rate savings than H.265 for high-resolution scenarios, and in some tests it outperforms AV1 in terms of compression efficiency. However, AV1 has advantages in being royalty-free and having good software/hardware support in certain ecosystems. The trade-offs are in complexity, license cost, and existing infrastructure.
8. For OTT platforms, what are the operational benefits of supporting H.266 / VVC?
Benefits include lower bandwidth usage for delivering high-quality streams, reduced storage and CDN costs, better performance in constrained network conditions, support for future content workflows (4K/8K, VR/360°), and improved user experience (less buffering, sharper video).
9. How soon might H.266 / VVC become a mainstream standard for streaming?
While the standard is stable, mainstream adoption depends on hardware support (decoders in TVs, chipsets), licensing clarity, encoder/decoder software maturity, and infrastructure updates. It may take a few years before H.266 becomes widespread for consumer streaming.
10. Does Vodlix support H.266 / VVC, and how does that help platform owners?
Yes. Vodlix is structured to evolve with next-generation codecs including H.266. For platform owners, this means future-proofing: when H.266 support becomes more widespread, Vodlix clients can take advantage of reduced operational costs (bandwidth, storage), superior quality delivery, and better performance for global audiences.
