X265 vs. X264 — What's the Difference?
X265 encodes video using the H.265/HEVC compression standard, optimizing for higher efficiency, while X264 uses the H.264/AVC standard, widely adopted for HD video.
Difference Between X265 and X264
Table of Contents
X265 is a software that encodes video files into the H.265/HEVC compression standard, offering improved compression efficiency. On the contrary, X264 is an encoder for H.264/AVC, which is an earlier standard commonly used for HD videos.
In terms of file size, X265 tends to produce smaller files with equivalent or even superior quality to X264. The efficiency of X265 makes it particularly suitable for 4K or higher resolution videos where storage space is a concern.
From a technical perspective, the major advancement with X265 is its improved compression algorithm, which provides better quality at lower bitrates. X264, although slightly older in its technology, remains a reliable and widely accepted choice for HD content.
Compatibility is one area where X264 has an advantage. Since H.264/AVC is more established, a wider range of devices and players support X264 encoded files. X265, being newer, might not be supported on older devices without the right software.
To summarize, while X265 is the newer, more efficient encoder tailored for the evolving needs of high-definition content, X264 still stands strong due to its wide acceptance and compatibility.
