Tech Hack: What Is the AV1 Video Codec and What Is It Used For?
AV1 is a video codec that was developed by the Alliance for Open Media (AOMedia), a consortium of major technology companies including Google, Amazon, and Netflix. It is designed to provide improved compression efficiency over existing codecs such as H.264 and HEVC, while also being royalty-free and open-source.
The development of AV1 started in 2015, and the first version of the codec was released in March 2018. Since then, it has been rapidly gaining popularity and support from various hardware and software vendors, as well as content creators and streaming services.
One of the key features of AV1 is its ability to achieve better compression efficiency than other codecs, which translates into smaller file sizes and lower bandwidth requirements for streaming or downloading video content. This is achieved through advanced compression techniques such as tile-based processing, improved motion estimation, and enhanced entropy coding.
Another advantage of AV1 is its flexibility, which allows it to support a wide range of resolutions, color spaces, and frame rates. It also includes features such as HDR (high dynamic range) and 12-bit color depth, which can provide better color accuracy and contrast in video content.
AV1 is supported by major browsers such as Chrome, Firefox, and Edge, as well as popular streaming services such as Netflix, Amazon Prime Video, and YouTube. However, due to its relatively recent introduction, some older devices or software may not support it natively, requiring additional software or hardware support.
Tech Hack Use of AV1 video codec
AV1 video codec can be used in various applications where high-quality video compression and efficient streaming are required. Some of the common applications include:
- Video streaming: AV1 can be used for streaming high-quality video content over the internet, especially in scenarios where bandwidth is limited. Streaming platforms such as Netflix, Amazon Prime Video, and YouTube have already started using AV1 to offer better video quality at lower bitrates.
- Video conferencing: AV1 can be used for video conferencing applications, where high-quality video compression is required to ensure smooth communication over low-bandwidth networks. Video conferencing platforms such as Zoom and Microsoft Teams are already working on integrating AV1 support.
- Virtual reality: AV1 can be used to compress high-resolution 360-degree video content for virtual reality applications, allowing users to experience immersive environments with high-quality visuals.
- Gaming: AV1 can be used to compress high-quality video game streams, allowing gamers to stream and share their gameplay experiences with others.
- Broadcasting: AV1 can be used for broadcasting live events such as sports, concerts, and news, where high-quality video streaming is required over limited bandwidth.
Overall, AV1 video codec provides an excellent alternative to existing codecs, offering better compression efficiency, flexibility, and royalty-free licensing, making it an ideal solution for a wide range of applications

Advantages of AV1 video codec
There are several advantages of using AV1 video codec over other codecs:
- Better compression efficiency: AV1 offers better compression efficiency than other codecs, which translates into smaller file sizes and lower bandwidth requirements. This is especially useful for streaming video content over the internet, where bandwidth is often limited.
- Royalty-free licensing: AV1 is a royalty-free codec, which means that content creators and service providers do not need to pay licensing fees to use it. This makes it a cost-effective option for businesses and individuals who want to create and distribute video content.
- Open-source: AV1 is an open-source codec, which means that its source code is freely available and can be modified and improved by anyone. This can lead to faster innovation and development of new features.
- Flexible: AV1 is a highly flexible codec, which means that it can support a wide range of resolutions, color spaces, and frame rates. It also includes features such as HDR and 12-bit color depth, which can provide better color accuracy and contrast in video content.
- Future-proof: AV1 is designed to be future-proof, which means that it can adapt to new technologies and video formats as they emerge. This makes it a good long-term investment for businesses and individuals who want to create and distribute video content.
Is AV1 better quality than MP4?
While AVI seems to be the better media container for quality, it uses very large file sizes; hence, may require compression to smaller file formats. MP4, on the other hand, uses smaller file sizes and works with almost all media players but has an inferior video output quality compared to AVI.
What is AV1 used for?
AV1, like most other video codecs, is used to compress a video file or stream to a lower bitrate (smaller file size) while preserving and maximizing the visual quality. In this regard, AV1 outperforms incumbent codecs HEVC and VP9 by roughly 30% and H264 by roughly 50%.
Is AV1 better quality?
AV1 is the new gold standard video format, with superior efficiency and quality compared to older H. 264 and H. 265 formats. It is the most recent royalty-free, efficient video encoder standardized by the Alliance for Open Media.
Which is better AV1 or HEVC?
Summary: AV1 codec is 30% more efficient than H.265
According to tests conducted by Moscow State University, AV1 can outperform HEVC by about 28% in the encoding and decoding efficiency.
What is the full form of AV1?
AOMedia Video 1 (AV1) is an open, royalty-free video coding format initially designed for video transmissions over the Internet.
What are the disadvantages of AV1?
The primary drawback to AV1 at this time is that it is very new, and support is still in the process of being integrated into most browsers. Additionally, encoders and decoders are still being optimized for performance, and hardware encoders and decoders are still mostly in development rather than production.
What speed is AV1?
3.5 Mbps is the Sweet Spot for AV1 Live Streaming
The 3.5 Mbps results are where we see the most gains out of Intel’s AV1 encoder. This encoder is so good at 3.5 Mbps that it was able to outperform both Nvidia’s and AMD’s encoders at 6 Mbps with nearly half the bitrate.

As an AI language model, I don’t have access to current market prices or licensing fees for AV1 video codec. However, the AV1 codec is developed and licensed by the Alliance for Open Media (AOMedia), a non-profit organization dedicated to developing open, royalty-free video codecs. This means that the codec itself is free to use and distribute, but there may be associated costs with implementing it in software or hardware products, such as development and testing costs, patent licensing fees, and royalties for certain use cases. These costs can vary depending on the specific implementation and intended use case, so it’s best to consult with AOMedia or a licensed vendor for more information.
