Using the Quicktime conversion options provided in iMovie, it’s quite simple to import a movie in one format and then convert it to another format, including turning an .avi file to a .mp4 – also called a MPEG-4 video file. Even if you don’t have any experience working with the video editing program, you should be able to accomplish this task with little hassle. Depending on the length of your video, the longest part of the process will likely be waiting for the file to save as a Quicktime file.
