While trying to play some of your favorite videos with HEVC format on your system, you might face the same. But why do you fail to play it and how can you fix it? Well, this article will give answers to all your questions. We will give you a thorough knowledge about the HEVC, its working, and how to fix its issues.

Part 1: How HEVC works?

HEVC or High Efficiency Video Coding is the new video compression format that promises to perform better than past standards like H.264/AVC. Here you will learn everything related to HEVC and how to use it for your high-quality media files.

What is HEVC?

HEVC is a new form of video compression that gives better performance than previously used standards. The source video is compressed using an HEVC encoder. It creates and stores a compressed bit stream that can be decoded into a sequence of frames using a video decoder. High Efficiency Video Coding is similar to the previous H.264/AVC and MPEG-2 but has improved vastly.

HEVC format vs. H.264

A video is HEVC-compatible if it meets the compressed format requirements and if it can be decoded easily through the method described. You can store HEVC videos as files, transmit them through broadcast or stream them over the internet.

HEVC has many new features and improvisations over previous standards:

Why HEVC matter?

HEVC matters a lot in today's world, and you will get a lot of benefits and advantages by using this standard.

The global demand and support for HEVC videos are still developing, but it is clear that it is the future in this field.

How HEVC Works?

High Efficiency Video Coding is basically similar to the previous standards and involves a source video with a sequence of frames. An encoder encodes the video into a compressed bitstream and proceeds to store or transmit it. Then the decoder creates a sequence of frames by decompressing the bitstream.

Working of HEVC encoder and decoder

Video Encoder

The encoder will, first of all, divide every picture into many smaller units. Then it predicts each unit through intra or inter prediction and removes the prediction from the original unit. The residue left after this subtraction is transformed, and entropy encoding is done to all the information.

Video Decoder

The decoder will reverse the steps performed by the encoder. First, it performs entropy decoding and extracts various elements of the encoded bitstream. It rescales and inverts the transforming stage before predicting the units and adding the prediction to the inverted transform. Finally, it will reconstruct the decoded video for you.

Part 2: Why HEVC for high quality videos?

Every type of video clip on your phone, PC, TV, etc. has a specific file format, and you should know how they work so that the media work properly. A smartphone format may not work on your TV and vice-versa. The format stores the visuals, audio, subtitles, and other data related to the file. The encoded audio and visual parts are always stored in a particular format.

Different file formats

You must know about various file formats so that you choose the perfect one for your video. Read briefly about the most common formats available to use and learn about their features and uses.


MP4 was introduced in 2001 and was one of the first video file formats. It is compatible with most of the devices and operating systems. High-quality data is stored in smaller sized files.


Designed by Apple, it is another popular video file format that was initially made to support Quick Time media player. It takes up larger spaces and works on both Windows and Mac.


This file format is mainly used for HD recording and playback. Panasonic and Sony developed the file format specifically for HD video content. Its latest version can even support 3D videos.


Google introduced WebM in 2010 and it was meant for using with HTML5. It does not require high-end processors to decode and unzip files. This helps watching high-quality media on any kind of device easily.


As explained above this High Definition Video Encoding is a successor of widely used AVC, H.264 and MPEG-4. It offers better data compression and improved video quality without changing the bit rate.

Why prefer HEVC format?

Benefits of HEVC

Nowadays, the world is moving towards 4K content, especially on TVs. However, these media are hard to download and watch because they take up big spaces. But, with the use of High Efficiency Video Coding or H.265 format, this issue can be resolved.

Because of the improved efficiency, HEVC is the future, and you should upgrade as soon as possible to stay updated in the digital world.

Part 3: How to Play HEVC Video on Windows 10?
