How do you convert an iMovie project file?

The iMovie project file is only supported by iMovie itself and the right iMovie version is required. You have to open the iMovie project file and export it as a video file before converting it to the format you want. See below about how to export a video from an iMovie project file. 

1. Open iMovie and go to Share > Export Using QuickTime... in the top menu bar. Thie way, you'll get a .MP4 video file.
2. Next, import the MP4 video it to our application to edit it, apply effects and convert it to a format you want.

If you don't know how to use it, visit our site for the corresponding guide or go to Help > Online Help on top to open online tutorial of the application.
