So I am in the process of converting all of my DVDs and Blu-ray‘s to digital files. One of my Blu-ray‘s, a television series, is proving a little harder to convert. Each disc contains three episodes. The three episodes rip on to 1 MP4 file. I would like to take that file and separate into three individual files, Each one containing one episode. Can someone please tell me how to do this? I am not very good with iMovie. Does anyone know the step-by-step instructions of how to accomplish this? Thanks in advance! PS I am using a brand new MacBook Pro with High Sierra, and the latest version of iMovie.
