Part 1: Common Problems when Importing MP4 files to iMovie 

iMovie is one of the ideal video editing tools for Mac users. However, the point here, sometimes still you will find it a painful experience to working MP4 in iMovie. And there are frequently asked questions quoted below:

Q: I imported an MP4 file to iMovie '11, and it goes through the copying process, but nothing showes up on screen.

Q: MP4 played just fine in QuickTime, but they "grey out" in the import window, so I couldn't import to iMovie '09.

Q: I can import my MP4 clips into iMovie, but when I play them, there's an image but no sound.

Q: My MP4 plays smoothly in QuickTime, but in iMovie '08, I get audio but no picture.

Part 2: The Simple Solution: Convert MP4 to an iMovie-Compatible Format

Actually, this is due to the MP4 files codec: Officials said DV, MPEG-4, MPEG-2, MOV and M4V file types are compatible with iMovie. Though the MP4 file format defines the storage of MPEG-4 audio, scenes and multimedia content using the ISO Base Media File Format, the MP4 file may also contain any number of audio, video, and even subtitle streams. So it is impossible for the MP4 file to determine the type of streams in an MPEG-4 file based on its filename extension alone. 

If you are unable to locate your MPEG-4 files into iMovie, a recommended solution is to convert MP4 to imovie supported formats like AIC .mov.
