About .mmv Files
MMV files are movie capture files used by the Dega Movie capture tool.
They carry the MIME type application/octet-stream, which means they contain binary data not tied to a specific format.
- Main Use: Storing video capture data during recording sessions.
- Content: They may include video frames and metadata from the capture process.
- Viewing/Editing: They open with specialized video capture or editing software, typically the Dega application.
- Technical Note: The generic binary MIME type indicates no standardized structure for common software.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is an .mmv file?
An .mmv file is a movie capture file created by the Dega emulator, which is used to play Sega Master System and Game Gear games on a PC. These files record gameplay sessions, storing the data required to replay a game exactly as it was played.
How do I open an .mmv file?
You must use the Dega emulator to open these files. Because the file typically contains input data rather than standard video frames, generic media players like VLC or Windows Media Player cannot open them.
Can I convert an .mmv file to MP4 or AVI?
Direct conversion is usually not possible with standard video converters. To convert it, you generally need to load the file in Dega, play it back, and use the emulator's built-in "Log to AVI" feature or a separate screen recording tool to capture the footage as a standard video format.
Why does my .mmv file have the application/octet-stream MIME type?
The file uses the generic application/octet-stream MIME type because it is a proprietary binary format without a standardized web definition. This tells the operating system to treat it as arbitrary binary data rather than a specific document or media type.
Are .mmv files the same as Sony MicroMV videos?
While they share the extension, Dega capture files are distinct from Sony MicroMV tapes. If your file was not created by the Dega emulator, it might be a MicroMV video, which requires different software (like Sony video editing tools) to view.
Is it safe to delete .mmv files?
Yes, if you do not need the gameplay recording, it is safe to delete these files. They are standalone output files and deleting them will not affect the functionality of the Dega emulator or your computer.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
