Thank you for using VCUS. Your edits won’t be saved if any of the following situations occur: 1. The video was edited using VCUS Pro features. You need to join VCUS Pro to save videos edited using paid effects. 2. There is not enough storage space on your device. Please free up some storage space before trying again. If none of the above apply and the problem persists, try to uninstall and reinstall VCUS. If that doesn't fix the issue, please contact us and we will do our best to solve the problem.
