AV2 Streaming Quality: When It Arrives

AV2 (also known as Versatile Video Coding or H.266) will bring higher quality streaming when it is widely adopted by streaming platforms, device manufacturers, and video encoders, with the first mainstream deployments expected around 2025-2027. You will not see AV2 in Netflix or YouTube tomorrow, but the technology is already finalized, and the transition is happening in stages. This article explains what AV2 is, how it improves over current codecs like AV1 and HEVC, and what you need to know to prepare for it.

What is AV2 and Why Does It Matter?

AV2 is the next-generation video compression standard being developed by the Joint Video Experts Team (JVET), the same group that created HEVC (H.265) and VVC (H.266). It aims to reduce bitrate by about 30% compared to AV1 at the same visual quality, which means streaming services can deliver 4K and 8K video with less bandwidth, or higher quality at the same bitrate. For consumers, this translates to faster loading, less buffering, and better picture on limited connections. For providers, it lowers delivery costs significantly.

The Current State: AV1 and HEVC

To understand AV2’s timeline, look at its predecessors. HEVC (H.265) was finalized in 2013 but didn’t become the default for web streaming until around 2018, when hardware decoders appeared in smartphones and browsers. AV1, finalized in 2018, took even longer to reach ubiquity; as of 2024, it is the preferred codec for streaming on YouTube and Netflix, but only on devices with dedicated AV1 decoding chips, which are common in phones from 2020 onward but still absent from many older PCs and smart TVs. AV2 follows the same pattern: the standard is set, but widespread use depends on hardware support, which typically takes 5-10 years after finalization.

How AV2 Works: Key Technical Improvements

AV2 builds on the block-based hybrid coding framework of its predecessors but introduces several advanced tools that improve compression efficiency. These include:

• Neural network-based tools: AV2 allows for optional neural network filters to enhance prediction and reconstruction, though these are not mandatory for all decoders.
• Improved intra prediction: More angular modes and better prediction of complex textures reduce redundant data.
• Enhanced transform coding: New transforms and coefficient coding methods pack data more efficiently.
• Advanced motion compensation: Finer motion vectors and affine models handle movement better, reducing artifacts.

These tools are computationally heavy, which is why AV2 encoding is currently only practical for large-scale cloud encoders, not consumer software. The first hardware decoders are expected in 2025-2026, and software decoders may appear earlier but with slower performance.

When Will AV2 Actually Arrive in Streaming?

The realistic timeline for AV2 in streaming services is as follows:

• 2024-2025: Finalization of the standard (expected late 2024) and initial encoder development by companies like Fraunhofer and Tencent.
• 2026-2027: First hardware decoders in flagship smartphones and GPUs (e.g., NVIDIA, AMD, Apple, Qualcomm).
• 2028-2030: Mainstream adoption by streaming platforms for new content, starting with 8K and premium 4K tiers.
• 2030+: Full transition, with AV2 replacing AV1 and HEVC for most streaming, similar to how AV1 is replacing HEVC today.

But note that streaming services are conservative because they must support a wide range of devices. They will offer AV2 as an additional stream, not a replacement, until a majority of users have compatible hardware. You will likely see AV2 first on high-end smart TVs and streaming sticks, then on mobile, and last on web browsers.

How to Check if Your Device Supports AV2

There is no consumer-friendly way to check AV2 support yet because no devices support it. But you can prepare by looking for future hardware specifications that mention “AV2 decode” or “H.266” support. When buying a new phone, laptop, or TV in 2026 or later, check the chipset’s video decode capabilities. For now, focus on AV1 support, which is a good indicator that the manufacturer is forward-thinking about codecs.

Common Misconceptions About AV2

One common myth is that AV2 will require new internet infrastructure. It does not; it works over existing networks. Another is that AV2 will make 8K streaming practical on all connections. In reality, 8K still needs roughly 40-60 Mbps even with AV2, which many connections cannot sustain. Also, some believe that AV2 will be free to use, but while the standard is royalty-bearing, major companies have pledged to offer it under reasonable terms, similar to AV1. The actual licensing costs are still being negotiated, and they could affect how quickly smaller platforms adopt it.

How to Choose a Codec for Your Own Streaming

If you are a content creator or platform, the decision to use AV2 depends on your audience’s hardware. For most, sticking with AV1 or HEVC is still the right choice until 2028. If you want to test AV2, you can use the reference encoder software from JVET, but it is extremely slow and not suitable for production. The practical advice is to monitor the progress of hardware support and re-evaluate annually. For viewers, there is nothing you need to do now; your device will automatically select the best codec when AV2 becomes available.

Frequently Asked Questions

Will AV2 work on my current TV or phone?

No. AV2 requires hardware decoding, and current devices lack the necessary chips. Software decoding is possible but too slow for real-time playback. You will need a device manufactured after about 2026 to use AV2.

Is AV2 the same as H.266?

Yes, AV2 is the informal name for Versatile Video Coding (VVC), officially known as H.266. The names are used interchangeably, though “AV2” is more common in the streaming industry.

Will AV2 make my internet faster?

No, but it will make your streaming more efficient. You can watch higher quality video at the same bitrate, or the same quality at a lower bitrate, which reduces buffering on slow connections.

What is the difference between AV1 and AV2?

AV2 is about 30% more efficient than AV1, meaning it can deliver the same quality with 30% less data. It also includes newer tools like neural network filters, but it requires more computational power to encode and decode.

When will YouTube or Netflix start using AV2?

Likely not before 2027. These platforms prioritize compatibility with existing devices. They will first test AV2 on a small percentage of traffic, then expand as hardware adoption grows.

Do I need to pay for AV2?

No, consumers do not pay directly. Streaming platforms pay licensing fees to patent holders, which may be reflected in subscription prices, but there is no direct charge to you.
