Well, you can’t edit a MP4 video directly in Final Cut Pro including the lastest FCP X and problems may occur as above quoted words described. In fact, MP4 is a final delivery file type, and is heavily compressed. You need to change the file extentsion from “.mp4” to “a codec” that FCP can read more easily (without rendering basically).
Handbrake is a free app for you to convert MP4 to MOV. Also, you can seek for a professional video converter that brings you ProRes codec,which is the most compatible format for Final Cut Pro.
