When importing M4V files to an editing program like iMovie for real-time editing, there are two major and same problems that people are running into: iMovie cannot import M4V files; M4V files can be imported to iMovie but the editing just does not work at all. Not only iMovie users, people who use Adobe Premiere, Avid MC, FCP and Davinci Resolve are also upset by those annoying importing and editing issues.
Editing programs are usually quite demanding in accepting and editing a video file. So what you have to do is make every step go right, and reduce mistakes to zero!
