MultiMedia Movie Format (RIFF RMMP) | Microsoft Corporation | Video Files |
MMM (MultiMedia Movie) file extension belongs to the RIFF RMMP files category. The MMM file is a video file created with Macromedia Director using the Shockwave Multiuser Server technology. The MMM file type is commonly used for software applications that require high-level multimedia elements such as interactive e-commerce, video streaming, gaming, data delivery, and more. The MMM File format is based on the RIFF (Resource Interchange File Format) which was originally developed as a multimedia data interchange from Microsoft.
Technical Details
The Macromedia Shockwave Multiuser Server technology uses the RIFF-RMMP standard, a faster version of the earlier RIFF format, which reduces file size and increases compression. It is important to note that while both RIFF and RMMP files can be opened with any media player, such as Windows Media Player or QuickTime, only RMMP files can be played on web-based applications alone. An MMM file consists of several chunks of data including an information chunk, a data chunk containing an audio stream, and a header chunk containing the width and height of the movie's display window.
Similar file extensions include - RM,.RAM,.RMV,.SMIL.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .MMM) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .MMM extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .MMM file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .MMM extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .MMM extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .MMM file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .MMM file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .MMM file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .MMM file) will be extended to the maximum.
It is also good to check
- if the .MMM file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
