Part 3: FAQs about Fixing QuickTime Player Won’t Play MOV.Part 1: Why QuickTime Player Won’t Play MOV? Just as mentioned, MOV is a QuickTime-supported video file. If there is a problem with encoding and decoding, QuickTime Player cannot open the MOV files directly. MOV is a container format for a variety of different video and audio codecs, not a simple file format. It contains many different audio and video encoders, such as MPEG-4, AAC, etc. When QuickTime Player cannot open MOV, it is likely the computer is not ready to read the codec of the file. If any specific encoding in the MOV file cannot be recognized quickly, the MOV file cannot be played. You can either change the video codec for the MOV, or use another MOV player.
