Certainly. Just make sure you have the latest version of Quicktime installed on your computer, per the program's requirements.
On the other hand, MOVs are just a package and come in hundreds of flavors. So it all depends on what model of camcorder the video is coming from, its resolution, frame rate and, above, its codec. But if you can identify the codec and the video is coming from a consumer camcorder, you can certainly edit it. (MJPEG-MOVs from many still cameras can be a challenge though.)
What model of camcorder is your video coming from?
Welcome to the forum.
Along with Steve G's comments on the CODEC's possible in the MOV wrapper, I wish to add that some are Mac-specific, and a few, like the Apple Intermediate CODEC, will only work if one has Final Cut Pro on the computer.
It is what's "inside" the MOV format, that will determine whether you can edit the file. For most, the answer is yes, but for some, that answer is no. It just depends.
