About .mlt Files
MLT files are used by Shotcut as project files that store editing data in an XML format. They save timeline information, clip details, transitions, and effects in text form.
These files use the MIME type text/xml, which means they are structured as XML documents. They can be opened with any text editor, but they work best with Shotcut, the video editing software that creates them.
- Main use case: Saving project details for video editing in Shotcut.
- Content: XML data defining timeline, media references, effects, and project metadata.
- Software: Primarily opened and edited with Shotcut. Text editors can also view the XML code.
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
How do I open an MLT file?
You should open .mlt files using Shotcut, a free and open-source video editing application. Since the file contains project data rather than a finished video, double-clicking it usually launches Shotcut and loads your timeline, provided the software is installed on your computer.
How can I convert an MLT file to MP4?
You cannot convert an .mlt file using a standard online converter; you must export the project from within Shotcut. Open the project in Shotcut, click the Export tab, choose a video preset (like H.264 High Profile), and click "Export File" to render the final .mp4 video.
Why won't my MLT file play in a media player like VLC?
An .mlt file is a project file, not a playable video file. It contains XML text data describing edits, transitions, and file locations, but it does not contain the actual video and audio streams. To view your work in a media player, you must export the project as a standard video format.
Why does my Shotcut project say "INVALID" or show white blocks?
This error occurs when the source media files referenced inside the .mlt file have been moved, renamed, or deleted. The project file relies on specific file paths to locate your video clips; if those paths change, you must use the "Repair" dialog in Shotcut to locate the missing files.
Can I edit the MLT file with a text editor?
Yes, because .mlt files are based on XML and often utilize the standard MIME type text/xml, you can view and edit the raw code in editors like Notepad++ or Sublime Text. This is useful for advanced users needing to batch-replace file paths or inspect specific filter parameters manually.
Are MLT files compatible with Adobe Premiere or DaVinci Resolve?
Generally, no. .mlt files are specific to the MLT Multimedia Framework used by Shotcut and Kdenlive. Major commercial editors like Adobe Premiere Pro or DaVinci Resolve do not natively open these files, though complex workarounds involving EDL (Edit Decision List) exports may be possible.
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.
