About .idx2 Files
IDX2 files are plain text files that serve as index guides for Avidemux video projects. They mark specific video points or chapters to help streamline editing.
They are stored in a simple text format, as indicated by the MIME type text/plain.
- Main Use: Indexing video frames or sections in Avidemux.
- Other Uses: Tracking chapters, timestamps, or scene markers.
- Software: Openable by Avidemux and any text editor.
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 IDX2 file used for?
An IDX2 file is an index file created by the video editing software Avidemux. It maps keyframes and navigational points within a video file to allow the software to seek through the footage quickly and accurately. These files are automatically generated when you open certain video formats (like MPEG-TS) in Avidemux.
How do I open an IDX2 file?
You typically do not need to open this file manually; Avidemux uses it automatically when you load the corresponding video. However, since the file format is based on the text/plain MIME type, you can view its contents using any text editor, such as Microsoft Notepad, Apple TextEdit, or Notepad++.
Can I convert an IDX2 file to MP4 or AVI?
No, you cannot convert an .idx2 file into a video format like MP4 or AVI. The file contains only text-based index data and references, not actual video or audio streams. To get a video file, you must have the original video source that the IDX2 file is associated with.
Is it safe to delete an IDX2 file?
Yes, it is generally safe to delete an .idx2 file if you are not currently editing the video. If you reopen the original video file in Avidemux later, the software will simply re-scan the video and generate a new IDX2 file, though this process may take a few minutes for large videos.
Why does my computer think the IDX2 file is a text document?
Operating systems identify .idx2 files as text documents because they are structured as plain text and often share the generic text/plain MIME type. This allows you to inspect the frame data or settings inside the file without needing specialized software, although the data is intended for machine reading.
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.
