Follow the quick-start guide to learn how to convert MP4 videos for editing in iMovie without quality loss.
iMovie puts the basics of digital editing at your fingertips. It is a user-friendly program designed to be intuitive so that you can learn while you create. Recently a problem troubled me for days. iMovie won't import MP4, why? Sometimes, I can edit MP4 file in it successfully, but it also happens MP4 cannot added into iMovie. What's the solution?
As some guys explained, iMovie only accepts MP4 file which contains MPEG-4 and H.264 codecs. While, the audio, subtitle or other media source that embed in MP4 might have different codecs. In this case, we cannot judge the video format by examining the file extension name only. Then, providing that you want to add MP4 to iMovie, the common advice is to convert your MP4 to iMovie preferred format like Apple InterMediate Codec .mov, which will save you both time and trouble, and all you need is to drag the result videos for prompt editing.
