What is a MLT File Type?
Select File → New to create a new project in Shotcut. After modifying the project, the user can save the information in an MLT file by selecting File→ Save or save under.... After registering a project, the user can close the project and reopen it later for the edits.
Users can also export recorded Shotcut projects from MLT files to different formats, including .MP4 and .WMV videos, .MP3 and .AAC audio, and .JPG and .PNG images. To export a project to a different format, select File → Export Video... or Export Frame....
While an MLT project file should only be open to Shotcut, it can also be opened with an XML editor to view the parameters in XML format. The MLT file, however, should not be modified with an XML editor, as the editing of the content is likely to corrupt the file.
