HEVC (High Efficiency Video Coding) codec, also known as H.265, is a technology used in Windows to compress and decompress videos. Being the successor to the popular H.264 (or AVC) codec, HEVC offers significantly greater efficiency when it comes to video compression, which translates into better image quality with smaller file sizes.
HEVC is widely used in a variety of applications where video compression efficiency is important. For example, platforms such as Netflix, YouTube, and other video streaming services use it to deliver high-resolution content (such as 4K) with lower bandwidth consumption.
This codec also allows more video to be stored on devices such as hard drives, smartphones and cameras without losing quality. It is also used in live broadcasts to reduce latency and maintain high image quality, especially in sporting events or broadcasts that are in 4K.
How HEVC works
HEVC has high compression efficiency, as it is able to reduce file size by up to 50% compared to H.264, while maintaining the same image quality.
In fact, it supports video resolutions from HD to 8K, allowing you to encode on a wide range of devices and applications. Not only that, it offers better visual quality, especially in scenes that have fast movements thanks to its advanced prediction and compression techniques.
HEVC works by dividing video frames into smaller, more complex blocks than previous codecs. It does this by using advanced algorithms to analyze and predict the motion of these blocks, allowing for more effective compression without sacrificing quality.
The process begins with the division of each video frame into smaller coding units, these are known as CUs (Coding Units), which dynamically adapt in size according to the needs of the content.
In addition, it uses advanced prediction techniques to reduce spatial and temporal redundancy, i.e. the repetition of information within a frame or between successive frames.
Once the video is compressed, it is stored in a reduced format. And, at the time of playback, that video is decoded again, although recovering the necessary information to show the original image with the highest possible quality.
Where to download the HEVC codec
To download the HEVC codec, you need to go to the Microsoft Store on your Windows operating system. Previously, this codec could be found on other platforms, but Microsoft has now integrated it into its official store.
It is important to note that the download is not free; it costs 0.99 cents. However, make sure that your device is up to date, as the codec is only compatible with Windows 10, version 16299.0 or later. By downloading, you can rest assured that you are getting the original version from Microsoft Corporation.
Download the free extension
Another option we recommend is HEVC Video Extensions from Device Manufacturer. This is the extension created by Microsoft, which has been designed so that you can take advantage of all the hardware capabilities of your device and enjoy playing content in 4K and Ultra HD.
The best thing of all is that you can install it on your computer at no cost. Here you also have to verify that your operating system is Windows 10, version 16299.0 or higher, as this is how you will be able to use all its features.
