My bf recorded a video on his phone (android) and I was not able to switch it over to imovie. When I drag it over it won't accept it. Someone said I needed to switch it over to something else then to imovie and it'll work. Switch it to what though??
Check this out. I use a different way to convert mp4 for import into iMovie, but this link should help you understand why it does not work sometimes and will give you the solution. http://www.bigasoft.com/articles/how-to-import-mp4-into-imovie.html. Quicktime Player 7 Pro will also convert them for you.
However, MPEGStreamclip is free and should do what you need. Open/view your video with it and then Export To Quicktime, and use the Apple Intermediate Codec option as this is what iMovie would convert your mp4 to if it could. http://www.squared5.com/svideo/mpeg-streamclip-mac.html
