How to share a 3-hour iMovie project with children from a 2017 iMac?
I just completed making an iMovie on my 2017 IMAC. The film's length is 3 hours 20 minutes long. I wish to share the project with my children. I have been unable to copy the file to a 32GB flash drive for a number of reasons, e.g. the file transfer is never completed; the photos and imbedded videos on the completed project are out of sequence; the audio but not the video is transferred.
What is the ideal way to copy the completed file to a medium or device that I can give to my children? I have worked on this project for months and am at my wits end. Please help.
