AV1 Video Extension (Beta)

Play AV1-encoded videos on Windows natively with this free codec extension.

Overview of AV1 Video Extension (Beta)

AV1 Video Extension (Beta) is a free codec add-on developed by Microsoft for Windows 10 and above, designed to enable native playback of AV1-encoded video files. The extension integrates directly with built-in applications like Movies & TV and Windows Media Player, allowing users to play modern AV1 content without third-party software or manual codec installations. As AV1 continues to grow in popularity for its efficient compression and robust video quality, this extension offers an easy way to stay current with evolving media standards.

Installation and Compatibility

The extension is available at no cost through the Microsoft Store. Installation is straightforward: after download, the codec is set up automatically, requiring no advanced configuration from the user. A system reboot may be needed to activate AV1 support in all compatible media apps.

To use the AV1 Video Extension, the system must run Windows 10 version 17763.0 (October 2018 Update) or higher. Older versions of Windows, such as Windows 7 or 8.1, are not supported, so users on those platforms will need to consider alternative codec packs or upgrade their OS for AV1 playback.

Performance and Playback Quality

Once installed, the extension allows native media players to decode and play AV1-encoded files. AV1 is renowned for delivering high-quality video with better compression than traditional formats like H.264 or HEVC. This means smaller file sizes and reduced bandwidth requirements for streaming and local playback.

Because this software is in its beta stage, users may encounter occasional performance hiccups, such as slow seek times, dropped frames, or compatibility limits with some hardware acceleration options. Video playback stability and smoothness can also depend on the processor, especially with high-resolution (4K and above) content, since not all GPUs currently support AV1 hardware decoding.

Use Cases and Practical Benefits

The adoption of AV1 is accelerating, particularly on streaming platforms such as YouTube, Netflix, and Vimeo, due to its royalty-free licensing and impressive efficiency. For users downloading, sharing, or archiving videos in AV1, this extension removes the hassle of searching for compatible third-party players or converting files to older formats. It also benefits users who want to keep their system streamlined, leveraging built-in Windows applications for their media needs.

Limitations and Considerations

The AV1 Video Extension is currently a work in progress, and not all AV1 streams or advanced features may work flawlessly. Power users seeking more control or those experiencing instability may still prefer established codec packs or dedicated third-party players with more advanced options. Additionally, some advanced AV1 functionalities (like 10-bit color or HDR) may not be fully supported, depending on the playback environment.

Summary

AV1 Video Extension (Beta) is a convenient solution for Windows users seeking effortless playback of AV1-encoded videos. Its integration with the operating system and ease of use make it a practical choice for most users, although its beta status means it may not match the reliability of mature codec solutions just yet.
