X264 File Extension

Have a problem opening a .X264 file? We collect information about file formats and can explain what X264 files are. Additionally we recommend software suitable for opening or converting such files.

What is the .X264 file type?

The .x264 suffix is used with HD (High-Definition) digital video files. It can appear both as an extension and part of a filename to point out that such files have their video tracks encoded with the x264 encoder. x264 is a popular open and free (GPL) cross-platform encoder library that implements the H.264/MPEG-4 AVC video compression. x264 is widely used to create highly-compressed video files with HD-like quality.

An .x264 file is a digital video file that contains a H.264/MPEG-4 AVC video stream encoded with the x264 encoder.

Most often, x264-encoded video tracks come in fact packaged into containers (like MKV) that also include audio tracks, subtitles etc. In case of MKV, such files would have the MKV file type (with the .mkv extension), with .x264 being part of the filename to indicate the video compression method and encoder.

X264 video files can be played with any multimedia player that can handle H.264/MPEG-4 AVC. For smooth playback, most modern platforms offer different levels of H.264 hardware acceleration support, as decompression of H.264 data is computationally intensive.
