What are 264 files and how to open them

Are you having problems opening a 264 file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your 264 files.

What is a 264 file?

264 files have multiple uses, and H.264 DVR video is one of them. Read more about the other uses further down the page.

H.264 DVR video

.264 files are video files in the H264 video file format. Files of this type are compressed video files stored on hard drives of digital video recorders and surveillance equipment like IP/CCTV cameras.

The high-definition video content of DVDs and Blu-Ray discs is often extracted as H.264 video streams if you "rip" the content of such a medium.

You can convert these files into other video file formats to save storage space or easy viewing on different devices.

Programs that open H.264 DVR video files

All known file formats using extension .264

While H.264 DVR video is a popular type of 264-file, we know of 4 different uses of the .264 file extension. Different software may use files with the same extension for different types of data.

Video Ripper Temporary Data

Files with the .264 extension are commonly associated with video ripping software. StaxRip and RipBot264 use this file extension for temporary video files. The 264 files are created when this software is used to extract video data that can be encoded into other video formats.

These files store the raw video data before the actual conversion occurs. They are normally deleted automatically after the video conversion is completed.

While we have not verified the apps ourselves yet, our users have suggested ten different 264 openers which you will find listed below.

HXV Video

We know that one 264 format is HXV Video. We have not yet analyzed in detail what these files contain and what they are used for. We're working on it.

HXVS Video

HXVS Video files are created by surveillance systems, especially low-cost Chinese IP or DVR cameras, to store video that has been encoded in H.264 format. These files use a proprietary container format - often labelled HXVS, HXVF, or HXVT - to wrap the actual video stream. The cameras record within this format when set to record H.264 video; playback requires software that can interpret this container so the underlying video can be decoded.

The container adds headers, indices, and markers that are not part of standard MP4 or raw H.264 streams. When a surveillance camera file is exported or viewed, special tools (like FFmpeg with HXVS support) are used to peel away the container so the video (and any embedded audio) can be extracted or converted. Within the camera's workflow the file is generated during recording, and then taken apart or played back by camera software or specialized video players.

Files begin with ASCII "HXVS" in the first four bytes and include further markers like "HXVF" elsewhere in the header. These tags identify which container format is used and whether the video uses H.264 or H.265 encoding. Decimal size fields follow some of these markers, determining how much valid data comes after them before the next section begins.
