.MTS files reside within a specific folder structure that is often required for the file to be used. This highly structured system of folders tells the appropriate software on the computer exactly what the file contains and how to best utilize it. Fortunately, most video editing and viewing software allows the user to bypass this complex folder structure by importing the .MTS file directly into the program. When attempting to copy .MTS files directly to the desktop, though, it is important to retain the folder structure in which they are contained.

Users can record their own footage, import other footage from outside iMovie, or bring pictures in for a still movie. Once there is footage to manipulate, users can add transitions, edit the clips, add effects, and tie music or voiceover to the footage.
