"I keep trying to open a .mov file in iMovie and it isn't doing it. Is that not a recognized file extension? Should I convert the video file somehow?"

MOV is a file format developed by Apple and it's one of iMovie supported native video formats for import. But the weird thing is that iMovie will reject to import some .MOV files created by iPhone, GoPro, Canon camera, DJI drone, and more. Or iMovie imports audio only or video only from MOV files for you. You can see the video, but the fact is you can't progress the correct format of sounds and clips in the video.

But MOV is a multimedia container format which contains various types of data encoded using one of several different codecs. iMovie only allows you to import the MOV videos with codec that iMovie can recognize.
