Specific composite shots can be saved to your computer. This makes it easy to import them into other projects.
To export a composite shot, locate it in the Media panel then choose Save As... from its menu.
Note that saving a composite shot does not include embedded composite shots or associated media.
If you need to create a template using multiple composite shots you should save it as a normal project, then import that project as described in Saving & loading projects.
Composite shots can be imported into a project using the Composite Shot option in the menu to the right of the Import... button in the Media panel.
