iMovie won’t import MP4 files? Fortuantely, there is an easy workaround to fix the issue. Let’s find it out here.
Normally, we would like to adopt iMovie to edit MP4 videos including YouTube MP4 videos, iTunes MP4 videos, GoPro HD MP4 videos, etc. in order to get better videos or more wonderful video files. Although iMovie says it supports MP4, sometimes you encounter problems importing MP4 files into iMovie for further editing. Well, that’s because iMovie prefers MPEG-4 and H.264 codecs instead of others while MP4 can contain various video codecs. So if you MP4 files are not accepted by iMovie, it’s probably because of the video codec incompatibility.
On the other hand, the MP4 codec is a final delivery codec it is not one you want to use for editing. To get MP4 and iMovie to play nicely, the easy workaround is to convert MP4 to a more-editing-friendly format, such as iMovie’s Apple InterMediate Codec. This will help you import the file correctly and saving the rendering time. Below I will outline how to convert MP4 to iMovie native supported AIC MOV in details.
Fisrtly, download a professional application to do the MP4 to iMovie conversion. The one used in the artilce – say, Brorsoft Video Converter for Mac (compatible with Mavericks and Mountain Lion) – is outstanding in the features of easy-to-use and fast conversion speed. It supports advanced encoders like Apple Intermediate Codec, ProRes and DNxHD, allowing you to convert MP4 video to seamlessly fit iMovie, Final Cut Pro, Avid MC, etc. With this feature, if you have no idea which target format you should choose for iMovie (no matter iMovie ’08, iMovie ’09, iMovie ’11, or iMovie HD), you can directly select AIC MOV as output, then the output video can work well on iMovie.

The following formats can be recognized by iMovie: DV, DV Widescreen, HDV 1080i (25 and 30 fps), HDV 720p (25 and 30 fps), MPEG 4 Simple Profile and iSight. If your videos are in these formats but iMovie still doesn’t accept them, you will need to re-encode the videos.
