What is MIME type "video/jpeg"?

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

The MIME type video/jpeg designates video data encoded as a series of JPEG images. It plays a role similar to Motion JPEG in that each frame is compressed individually, ensuring high-quality visuals despite larger file sizes.

This format is often used when each frame must be accessible on its own. It supports scenarios where frame-by-frame editing or analysis is needed. It fits well in applications that capture or process video in parts.

Used in video-capturing devices that save sequences of still images.
Utilized in media players and editing tools that support individual frame processing.
Beneficial in specialized software needing access to separate image frames for modification.

Files identified with this MIME type adopt the extension JPGV. Each such file stores a video as a continuous stream of JPEG frames.

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.
