You can edit movies directly on the XM5800 smartphone - it includes a basic movie editor similar to iMovie on it - you can cut, paste clips together, add effects and soundtrack, and text/titles directly on the phone, then upload the edited movie to your chosen online site.
To access the movie editor on the XM5800, go to the gallery application, choose a movie, then choose 'options', 'edit' then choose editing options.
