AV1 has moved from “promising future codec” to a practical choice for streaming, video apps, cloud media workflows, and new devices. It now competes directly with H.264, HEVC, and VP9, not just on compression, but on licensing, browser support, hardware decoding, and encoding speed. The main story is simple: AV1 gives better efficiency, but older codecs still win when compatibility matters most.
TLDR: AV1 can cut video bitrate by roughly 20% to 40% compared with H.264 at similar visual quality, which can lower bandwidth costs for large platforms. For example, a service delivering 1 million hours of 1080p video per month could save many terabytes of transfer if it shifts popular titles from H.264 to AV1. HEVC still has strong hardware support on TVs and Apple devices, while VP9 remains common on YouTube and Android. The best codec choice depends on audience devices, latency needs, and licensing risk.
Why AV1 Is Getting So Much Attention
AV1 was created by the Alliance for Open Media, with support from companies such as Google, Netflix, Amazon, Apple, Microsoft, Meta, Intel, AMD, Nvidia, and Samsung. That backing matters. Codecs fail when nobody ships them. AV1 is being shipped.
The biggest appeal is its royalty-free model. HEVC licensing has been messy for years, with multiple patent pools and uncertainty for some vendors. It drives me crazy that a technically strong codec like HEVC still comes with licensing confusion that can slow product decisions. AV1 was designed to avoid that pain.
AV1 also compresses better than the legacy options in many real-world cases. It can preserve more detail in shadows, gradients, animation, grain, and fast motion at lower bitrates. This is useful for 4K streaming, mobile video, cloud gaming, screen sharing, and social video uploads.
AV1 vs H.264: Efficiency vs Universal Support
H.264, also known as AVC, is still the safest codec in the world. Almost every phone, browser, TV, laptop, tablet, media player, and editing tool supports it. If you need one video file to play almost anywhere, H.264 remains the easy answer.
But H.264 is old. It was standardized in 2003. It works well, but it uses more bandwidth than newer codecs. AV1 often delivers the same perceived quality at a much lower bitrate. For streaming providers, that is not a small win. Bandwidth bills are real.
- H.264 wins: compatibility, fast encoding, old device support, live workflows.
- AV1 wins: compression efficiency, royalty-friendly distribution, modern streaming quality.
- Best use for H.264: fallback streams, enterprise video, email-friendly clips, broad device playback.
- Best use for AV1: high-volume streaming, 4K video, browser playback, bandwidth reduction.
The catch is that AV1 encoding can still take longer, especially at high quality settings. Modern encoders have improved a lot, but H.264 remains far quicker in many production pipelines. If your team needs thousands of files processed in minutes, not hours, H.264 is still hard to beat.
AV1 vs HEVC: Open Distribution vs Mature Hardware
HEVC, also called H.265, is efficient and widely used for 4K Blu-ray, broadcast, iPhone video, smart TVs, and HDR delivery. It can beat H.264 by a large margin, often cutting bitrate by about 40% to 50% compared with AVC in ideal cases.
AV1 can match or exceed HEVC in many streaming tests. The difference depends on content, encoder settings, resolution, and target bitrate. AV1 often shines at lower bitrates, where every bit matters. It is also strong for web delivery because major browsers now support it.
HEVC’s main advantage is hardware maturity. Many TVs, set-top boxes, smartphones, and cameras already handle HEVC smoothly. Apple also supports HEVC deeply across iOS, macOS, and its camera pipeline. AV1 support on Apple hardware is newer, with hardware decoding appearing in recent chips such as the A17 Pro and M3 family.
Licensing is where AV1 gains ground. HEVC’s licensing history has pushed many web platforms toward AV1 or VP9 instead. For companies shipping apps across regions and device types, fewer licensing headaches can be a serious business advantage.
AV1 vs VP9: Successor Energy
VP9 was Google’s earlier answer to HEVC. It became popular through YouTube, Chrome, Android, and web video. It is still widely used and remains a practical option for many streaming workflows.
AV1 can be seen as VP9’s successor in spirit. It usually compresses better than VP9, though at the cost of heavier encoding. Browser support is also strong. Chrome, Firefox, Edge, and Opera support AV1. Android support has expanded, and hardware decoding is now common in many newer phones, GPUs, and TVs.
VP9 still has value because it is lighter to encode than AV1 and already deployed at scale. Some platforms keep VP9 for midrange compatibility and use AV1 for newer devices. That mixed approach makes sense. Honestly, it feels like the most realistic codec strategy right now: serve different formats to different devices and stop pretending one file can solve everything.
- VP9 wins: established web use, good Android support, easier transition from older YouTube-style workflows.
- AV1 wins: better compression, stronger long-term industry backing, more modern toolset.
- Best practical setup: AV1 for supported devices, VP9 or H.264 as fallback.
Recent AV1 Developments That Matter
The most useful AV1 progress is happening in three areas: hardware acceleration, encoder speed, and real-time use.
Hardware decoding is now available in many current GPUs from Nvidia, AMD, and Intel. Newer media chips in laptops, phones, and TV hardware also support AV1 playback. That reduces battery drain and makes AV1 viewing smoother. Hardware encoding is also improving, which helps live streaming and creator workflows.
Software encoders have improved too. SVT-AV1 has become a popular choice because it offers a better balance between speed and quality than early AV1 tools. Netflix and Intel helped push it forward, and it is now used in many encoding stacks. dav1d, the AV1 decoder from VideoLAN and collaborators, is also a major reason AV1 playback feels much less painful than it did a few years ago.
Real-time AV1 is another key shift. OBS Studio, Discord-style communication tools, cloud gaming platforms, and WebRTC projects have all gained interest in AV1 because it can improve quality at constrained bitrates. For streamers, that may mean cleaner 1080p video without raising upload speed. For video calls, it can mean fewer blocky faces when connections dip.
Where AV1 Still Falls Short
AV1 is not magic. Encoding can still be slow if you choose high-efficiency presets. File compatibility is not as broad as H.264. Older smart TVs may fail to play it. Some editing programs support AV1 import but struggle with smooth timeline performance.
There is also a workflow issue. Teams often need multiple versions of the same video: H.264 for older devices, HEVC for certain premium streams, VP9 for web fallback, and AV1 for newer clients. Expect to waste time on testing if your audience uses old TVs, low-cost Android boxes, or locked-down corporate laptops.
For live streaming, latency and hardware encoders matter. Nvidia, Intel, and AMD AV1 encoders are making this more practical, but H.264 still has a large advantage because every platform understands it. A creator streaming to a broad audience may still pick H.264 for safety, even if AV1 looks better at the same bitrate.
Which Codec Should You Use?
For most modern video platforms, the best answer is not one codec. It is a tiered delivery strategy.
- Use AV1 for supported browsers, newer phones, 4K streams, and bandwidth-sensitive delivery.
- Use H.264 as the universal fallback for older hardware and maximum reach.
- Use HEVC where Apple devices, smart TVs, HDR, or broadcast-style workflows are central.
- Use VP9 when you already have web pipelines built around it or need a lighter alternative to AV1.
AV1’s rise is not about killing every older codec overnight. H.264 will remain everywhere for years. HEVC will stay strong in premium devices and TV workflows. VP9 will keep serving large web libraries. Still, AV1 is now the codec to watch because it combines strong compression, broad industry support, and fewer licensing worries. For new streaming systems, it should be part of the plan from day one.
