X265 Vs X264

X265 Vs X264: Which is Better?

Video compression is increasingly becoming more and more important as video quality improves and file sizes get larger. Compression allows for on-demand video streaming, reduced storage requirements, and faster file transfer. Two of the most popular compression formats used today are H.264 and H.265, better known as X264 and X265 respectively. However, there is a persistent question of which format is better. This article explores the differences between X265 and X264 and finds out which is better.

X264 – An Overview

X264 is a widely used software library that provides video encoding for H.264/MPEG-4 AVC (Advanced Video Coding) standard. The H.264 standard is capable of delivering high-quality video at a low bit rate, making it ideal for video compression. X264 is commonly used in digital video cameras, video editing software, and other video production applications.

The X264 codec has been with us for over a decade and has undergone numerous improvements to make it faster, more efficient and better at video encoding. It is still widely used today and remains the preferred format for many video production professionals despite its limitations.

X265 – An Overview

X265 is a successor to X264 and is based on the H.265/MPEG-H HEVC (High-Efficiency Video Coding) standard. This new video encoding standard is designed to solve the limitations of the H.264 standard by delivering higher video quality at lower bitrates. This essentially means that it can compress video to a smaller size without compromising on quality. With X265, users can stream videos with high resolutions, such as 4K and 8K, while minimizing the bandwidth and storage required.

X265 offers improved video quality over X264, making it an attractive option for video producers. In addition, it offers increased processing speed, making it a more efficient video encoding option. The only downside of X265 is that it is more resource-intensive than X264, meaning it requires a more powerful computer to encode videos.

X265 Vs X264 – Format Comparison

There are a number of differences between X265 and X264 that we will compare in this section.

Compression Efficiency: One of the main reasons to switch from X264 to X265 is the improvement in compression efficiency. X265 is capable of delivering the same video quality as X264 but with fewer bits, resulting in smaller file sizes. This means faster video streaming, reduced storage requirements and faster file transfer.

Video Quality: X265 offers superior video quality over X264. This is because the X265 codec uses more advanced video compression techniques that provide better image detail, color accuracy, and brightness. This means the video appears more natural and visually appealing to the eye.

Processing Speed: X264 is faster than X265 at encoding videos, as it uses less complex algorithms. However, X265 has improved processing speed over the years, and the difference in speed between the two formats is becoming less noticeable.

Compatibility: X264 is compatible with almost all devices, including older devices or those with limited resources. On the other hand, X265 is relatively new and requires more processing power to decode videos. This makes it less compatible with older computers or mobile devices.

Hardware Support: Both X264 and X265 have hardware support for encoding and decoding videos. However, the hardware requirements for X265 are more stringent, requiring more powerful CPUs and more recent graphics cards.

File Sizes: X265 produces smaller file sizes than X264, making it a preferred option for streaming content on the internet. This reduces the amount of bandwidth required to stream the video, making it more accessible to users with slow internet connections.


1. Is X265 better than X264?

Yes, X265 is better than X264 in terms of compression efficiency and video quality. It delivers the same video quality as X264 but with smaller file sizes.

2. Should I use X265 or X264?

The answer to this question depends on your specific needs. If you want high-quality video with smaller file sizes, X265 is the better option. However, if you require video playback on older devices or those with limited resources, X264 may be a better option.

3. Can I convert X264 to X265?

Yes, you can convert X264 to X265 using a video conversion program that supports the two formats. However, some quality loss may occur during the conversion process.

4. Which codec is faster, X264 or X265?

Generally, X264 is faster than X265 at encoding videos. However, this difference is becoming increasingly smaller as X265 is improved.


X264 and X265 are two of the most popular video compression formats used today. X264 is a widely used and highly efficient codec that is still preferred by video production professionals, while X265 offers superior video quality and compression efficiency. The decision between X264 and X265 boils down to your specific needs, including compatibility with your devices, storage capacity, and the quality of video you require. Ultimately, both codecs have their strengths and weaknesses, and the right choice depends on factors specific to your individual circumstances.
