Yes, you can make a copy or duplicate of an existing project in the Clipchamp Create editor. This can be helpful if you want to keep an existing version of your video before making changes (so you can return to the old version later if you need to), or if you want to create two different versions of the same video (e.g. a 30 second edit and a 45 second edit).
To copy a project, go to your projects page. If you're in the editor, do this by clicking the film symbol in the top left of the window:
Under Your projects, find the project you want to copy and click the three dots in the top right of the image. From the drop down, choose Make a copy.
This will make a duplicate of your project, which you can now edit independently of the original.
If the copy doesn't appear immediately, try reloading the page.
The first time you open the copied project, you will likely need to relink the media files (the video, audio and image files you added to the original project). The quickest way to do this is by relinking the entire folder in which you keep the files – Create will only upload the ones relevant to the project.
