If your video requires different versions of the script, there is no need to duplicate the project or create a new one. Instead, all you have to do is duplicate the document within the project.
In essence, one video is one project. For each project, you can create various documents for the same video without needing to duplicate the project or create a new one.
1. Under Documents, click on the three dots to the right of the document you want to duplicate.2. Next, click on "Duplicate Document".
3. In the next window, select the document type you need and click on "Start".
