This is a camera file conversion failure. There are two solutions:
1. You can uninstall the software, turn off all antivirus systems and antivirus software on your computer, restart your computer and then re-install our software.
2. If the first method doesn't work, please try to install a software called Insta360 Studio, to convert video files manually within this software.
(NOTE : When using Insta360 Studio, please upgrade it to the latest version, Export 360video, DO NOT change the name of video)
