Have you encountered a problem with a H264 file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a H264 file here. In the further part of this page we have added a list of programs that should open your H264 file. It is enough you choose a proper application for your operating system, download and install it.


Files ending in H264 contain a video stream encoded using the H.264 method.

This process is also referred to as H.264 / MPEG-4 Part 10 or AVC (Advanced Video Coding) and is a standard for efficient, lossy compression of video data. It is mainly used for high-resolution material. For example, H.264 is used on BluRay discs, as a transmission format of HD channels and in Flash videos.

The bitstream contains only the encoded data without any further information, such as refresh rate or resolution. The file also contains no audio.

The extension is not necessarily recognized, but any player playing H.264 should be able to view the file. Occasionally, however, an H.264-capable container, such as MP4 or FLV because of the content with the extension H264 marked. This is wrong.

How to open a H264 file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the H264 file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a H264 file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support H264 files. At this point we are looking for disk space where the application was installed in and we can link it with a H264 file. Since then, our operating system will use the selected program to support all H264 files.

Other issues

Despite the described problem with H264 there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the H264 file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the H264 file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
