AV2 is the next-generation video codec currently being developed by the Alliance for Open Media (AOMedia), the same group behind AV1.
The goal of AV2 is simple but ambitious: deliver significantly better video quality while reducing bandwidth usage even further than AV1.
As streaming platforms continue to dominate the internet, more efficient codecs like AV2 are becoming essential for handling higher resolutions like 4K, 8K, and beyond.
What Is AV2?
AV2 is an experimental video compression format designed to replace or succeed AV1 in the future.
Like AV1, it is royalty-free and open, meaning companies can use it without paying licensing fees — unlike older codecs such as H.264 or HEVC.
This makes AV2 especially important for platforms like YouTube, Netflix, and web-based streaming services.
Why AV2 Matters
Video streaming is one of the largest sources of internet traffic worldwide.
Even small improvements in compression can save massive amounts of bandwidth at scale.
- Lower data usage for users
- Faster video loading
- Higher quality at the same bitrate
- Reduced infrastructure costs for platforms
AV2 aims to push these benefits even further compared to AV1.
Expected Improvements Over AV1
Early research suggests AV2 could achieve around 20% to 40% better compression efficiency than AV1.
This means the same video quality could require significantly less data.
Key technical improvements may include:
- More advanced motion prediction
- Improved transform coding techniques
- Better handling of complex textures
- Enhanced machine learning tools for encoding
The Downsides: Complexity and Hardware Support
Better compression usually comes at a cost: higher computational complexity.
AV1 already requires powerful hardware for efficient encoding and decoding, and AV2 is expected to be even more demanding.
This means:
- Slower encoding times (especially early on)
- Limited hardware support at launch
- Higher power consumption on some devices
Widespread adoption will depend heavily on hardware acceleration in GPUs, CPUs, and mobile chips.
Who Is Behind AV2?
The Alliance for Open Media includes major tech companies such as:
- Microsoft
- Netflix
- Amazon
- Intel
- Meta
These companies have a strong incentive to reduce bandwidth costs and improve streaming efficiency, which is why AV2 development is being closely watched.
When Will AV2 Be Available?
AV2 is still under active research and development and is not finalized yet.
A stable specification could take several years, followed by even more time before widespread adoption.
Realistically, AV2 may begin appearing in experimental tools before becoming mainstream later in the decade.
AV2 vs Other Codecs
AV2 will compete with existing and upcoming codecs such as:
- AV1 (current open standard)
- HEVC / H.265
- VVC (H.266)
The key advantage of AV2 remains its open and royalty-free nature, which is highly attractive for web platforms.
The Bigger Picture
AV2 is part of a larger shift toward more efficient internet infrastructure.
As video quality increases and AI-generated content grows, compression technology becomes even more critical.
The success of AV2 could shape how video is delivered across the web for the next decade.
