It is officially stated that AVI is supported by iMovie. There are some instances, however, that importing an .avi file into iMovie doesn’t go successfully. So what is the matter? Well it all depends. In fact, the iMovie only support MP4, M4V, MOV files and some types of AVI files. You may know that AVI file can be associated with three coedcs like AVI, XviD and DivX. Supposed that your handy .avi can’t be recognized by iMovie, it’s because of the AVI codec used to .avi file isn’t compatible with iMovie. Luckily, there is a smarter way to get rid of the incompatibility issues quickly. Simply convert the video files from AVI to a more editing-friendly format for iMovie.

Understanding AVI video files
AVI has some drawbacks that make it difficult to use for modern video and video editing software:
* It doesn’t have a standard way to represent time codes, so syncing audio and video is complicated.
* It doesn’t have a way to represent the aspect ratio of the video.
* It wasn’t designed to be used with video compression approaches where one frame is based on the frame that precedes it (like all modern methods)
* It doesn’t support the notion of variable bitrate (VBR) data, presuming that one can find a chunk of data by dividing the size of the video chunk by the duration
