While Celtx provides us the five standard industry formats, Film, Audio-Visual, Theatre, Audio Play, and Comic Books, we are not limited to them. In case, a different or non-standard format is needed, we can create and save them using the template engine feature.
To create a new template, open Celtx in the one of the five formats discussed previously. Click on the File button on the top menu bar, and then click on Create Template.... A Save Project dialog box appears. Enter the name and save it.
The name of the new template appears as a project type in the list on the splash page as Celtx starts and only opens the documents we want (that is, those created using that template).
To make that a bit clearer, we open a standard format (any of the ones provided), make the changes to the format we want, and then save it as a new template that we can use over and over again.
