Sometimes you may need to create several similar videos, but may need to alter them depending on your viewing audience. To save you time and effort, Synthesia has a duplicate option for your videos!
To duplicate a video:
Navigate to the video you wish to copy.
Click the three dots menu on the right hand side of the video.
Select the Duplicate option.
A copy of your video project is displayed on screen, that you can alter and edit, whilst maintaining your previous original project.
