About .ufmf Files
UFMF files are specialized containers for Micro Fly Movie Format videos. They use the MIME type video/ufmf to signal that they store video data.
These files are designed for precise, frame-by-frame capture and analysis, often used in scientific experiments and research projects.
- Main use: Recording high-speed video for behavioral or experimental studies.
- Additional uses: Storing sequential data for frame-by-frame analysis and custom research applications.
- Software: They generally require specialized tools. Programs like certain MATLAB toolboxes, Python libraries, or dedicated research software may be needed to open or convert these files.
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 a .ufmf file?
A .ufmf file is a video created in the Micro Fly Movie Format. It is a specialized video container primarily used in scientific research to record the behavior of fruit flies (Drosophila) and other small animals. The format is optimized to save disk space by storing a static background image and only recording the moving parts of the frame.
How do I open a .ufmf file on my PC?
You cannot open these files with standard media players like Windows Media Player. You typically need specialized research software such as Ctrax (The Caltech Multiple Walking Fly Tracker) or specific MATLAB toolboxes designed for behavioral analysis. If you are a developer, you can access the data using Python libraries.
Can I convert .ufmf files to AVI or MP4?
Yes, conversion is often necessary for viewing the video outside of research tools. The Ctrax software suite includes a utility called ufmf2avi which can transcode the specialized UFMF data into a standard AVI video file that can be played by most media players.
Why won't VLC Media Player play my .ufmf file?
VLC and other common players lack the specific codec required to decode the Micro Fly Movie Format. Because the file uses the niche MIME type video/ufmf, standard players do not recognize the compression algorithm used to store the frame data.
How do I read .ufmf files using Python?
You can read these files using scientific computing libraries such as Motmot or specific GitHub repositories like pyufmf. These tools allow you to parse the file structure and extract video frames as NumPy arrays for custom analysis or computer vision tasks.
What is the correct MIME type for .ufmf files?
The correct media type identifier is video/ufmf. This string tells software that the file contains video data formatted specifically for the Micro Fly Movie specification. You can learn more about how different video identifiers work at mime-type.com.
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.
