Add Template Title
Right-click on empty space in the project bin, or click the kdenlive-add-clipgo-downAdd Clip icon on the project bin toolbar, and select Add Template Title.

This opens a dialog window to select the template you want to use.
You must have created a title template before or just use the default templates.
Use %s anywhere in the title template to be replaced by text you enter for each instance of the template title.
Alternatively you can add template title inside the title app.
See the chapter Template Titles for more details.
