In case there are some issues with exporting the file in Movavi Clips, please try the below solutions:

1) Please, reboot your phone and try to run your program once again. Do not open any other programs while working on a project or exporting your video. We also highly recommend checking  the amount of free space on your device.

2) We also recommend removing all stickers and transitions from your video, and then save it.

3) Make sure that you have the latest version of the application installed.

4) Please also make sure that you have an up-to-date version of IOS installed on your device.
