Product overview and purpose

Microsoft’s HEVC Video Extensions enable playback and creation of High Efficiency Video Coding (HEVC) media on Windows devices. This codec is commonly used by streaming services to deliver high-resolution video such as 4K and Ultra HD, and the extensions allow Windows apps to decode and encode HEVC content natively.

Improvements to playback and visual quality

When a device includes compatible hardware, these extensions take advantage of the system’s video decoding capabilities to improve picture quality and performance. Benefits include:

  • More vibrant colors and increased image clarity
  • Smoother playback with reduced CPU load
  • Better handling of high-resolution streams such as 4K

If a system lacks dedicated HEVC hardware support (for example, older CPUs or GPUs), software decoding is still possible, but visual fidelity and smoothness will depend on the device’s CPU power and overall performance.

Encoding, supported devices, and workflows

Beyond playback, the extensions also permit creators to encode video in the HEVC format. Encoding is available even on machines without a hardware encoder, making it useful for a variety of workflows and devices, including:

  • HoloLens
  • Surface Hub
  • Mobile devices
  • Personal computers

This flexibility allows both consumers and creators to work with HEVC across different form factors.

Minimum requirements and licensing

To install and use the HEVC Video Extensions, your PC must be running Windows 10 version 16299.0 or later. The extensions are distributed as a paid product; there is no free trial or demo version available.

Practical notes and recommendation

Confirm your system meets the minimum OS requirement and check whether your hardware supports HEVC acceleration (for example, Intel 7th-generation Core processors or newer and updated GPUs) to get the best playback experience. If native hardware support is absent, expect variable results when decoding high-resolution content.
