Now, here is something important about iMovie formats. Generally, when we talk about a video or audio format, we mean the container format, which is basically what the file extension is. The container format is like a wrapper that contains video or audio streams or both and packages them together. Within each container format, the video or audio streams may use different codecs (a.k.a. compression formats) which are used to convert uncompressed videos to compressed ones. The compression format is what matters.
In the tables above, you can easily find the container formats that iMovie supports. iMovie typically supports MP4, MOV and M4V files. But not all MP4, MOV and M4V videos are compatible with iMovie. If an MP4 video contains compression formats (codecs) that are not accepted by iMovie, you won’t be able to import it. In a case like this, you need to use iMovie format converter to convert the file.
