Anniversary X264

The longevity of x264 can be attributed to its relentless pursuit of visual quality and speed optimization. Key technical contributions include:

Today, the spotlight has shifted to AV1 and H.265 (HEVC). AV1 offers roughly 30% better compression than x264 but requires significantly more encoding power. anniversary x264

The move to x264 also popularized the use of MKV (Matroska) and MP4 containers over the aging AVI format. The longevity of x264 can be attributed to

It has been adopted by billions of devices, from mobile phones to smart TVs. The move to x264 also popularized the use

Commercial encoders of the era were expensive and often proprietary. x264 began as a project to bring this high efficiency to the masses. Its initial goals were modest: a free, patent-encumbered encoder that could run on consumer hardware. However, thanks to a highly optimized C codebase and aggressive use of assembly optimizations (SIMD), x264 quickly outperformed many commercial reference implementations.
