In most cases, iMovie will have no problem to import MOV files. However, a lot of people complain that they encounter the following problems when loading MOV files into iMovie:
" MOV files imported into iMovie don't appear in iMovie or Finder but are still taking up a large amount of hard drive space. Help!"
"My GoPro .mov files won't import in new version of iMovie. For some reason all of my clips and edits are there with the sound, but there is no video."
"How do I import movie files into imovie that are .mov files saved in my iphoto? When I open the .mov file, the movie will only play in my quicktime viewer. How do I change the format so it is compatible with imovie? imovie will not let me import these files or drag & drop then into the program."
Why fails to import MOV to iMovie?
Like other multimedia container file formats like MP4, MKV, AVI, etc, the MOV files can store different types of media data. However, iMovie only supports MOV movie file whose codec is DV, MPEG-2, MPEG-4, H.264 or AIC, if the MOV video is encoded with other iMovie incompatible codec, you will definitely fail to load that file into iMovie or will suffer other playback issues even you have successfully drag and drop the mov video into iMovie's editing timeline.
