On iMovie, I tried to create a new project by importing a .mp4 file from my account on Youtube. The MP4 file plays but no sound. Why and what should I do? - Apple Support
The reason of iMovie MP4 No Sound: technically, iMovie does accept MP4 file with all its codecs. It only imports MP4 files encoded by MPEG4/AAC or H.264/AAC data. Yet, MP4 is a video container format that may contain various audio and video codecs (and sometimes even subtitle streams incl.). If the MP4 file is not encoded with iMovie support codec, iMovie won't import this kind of MP4 video. So the essence is to know best formats for imovie and convert MP4 to iMovie best codecs.
And apart from this, corrupted media player installation and corrupted MP4 files can lead to MP4 no sound problem as well. Simply uninstall the incorrectly installed media player and reinstall the right one (latest version recommended). Or resort to a video repair software to repair corrupted MP4. The last method is to load MP4 to iMovie alternative for further editing if it's still up in the air, Premiere Pro, Filmora, Avidemux, VideoProc Vlogger, etc.
