Files with the .MP4 extension contain audio and video streams encoded usually in the MPEG-4 format, but they are supported also by many other formats. It is a container – file, and it may also include metadata, subtitles or images, although it is rarely used for this purpose. It enables streaming within a network. Format is defined in the MPEG-4 Part 14 standard, based on the QuickTime format. It was originally standardised in 2001, and the current version was developed two years later. Information about content of different types of streams within the file is stored with a separate data stream.
The MP4 container is used by files with such extensions like:
The 3GP format is based on MP4 and is often used in mobile phones. MP4 files usually can be played in phones and MP4 players, although the latter not always provide support for this format, despite its name. MP4 is traditionally used to store videos mixed with sound, in a mediocre quality.
When you install one of the applications from the list of programs that you found here, you should be able to open or edit the file with the MP4 extension without any issue. However, if you still have problems with this, you may use the option of MP4 file conversion to a different format.
We hope we helped you solve the problem with the MP4 file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.
There can be more reasons which determine that you are not able to open the MP4 file (apart from the lack of the proper application installed).
First - the MP4 file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the MP4 file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the MP4 file should be solved.
Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the MP4 file has not been completed and it cannot be opened properly).
