What is MIME type "video/ufmf"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

video/ufmf is the MIME type for Micro Fly Movie Format videos. Files using this format carry the extension UFMF.
This format is built to capture rapid sequences of images in a compact, efficient way. It helps record high-speed events, often in laboratory experiments or specialized research settings.
Key functions and use cases:

Main use: Recording and storing fast-motion video data for scientific analysis.
Efficiency: Organizes long image sequences to reduce file size.
Application: Used in experiments where precise timing and frame-by-frame analysis matter.

Although not common in everyday media playback, specialized software can process these files effectively.

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 are multiple MIME types listed for one extension?

Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
