Q1: I have several video files from a Sony camera that I have placed on an external hard drive. The files are .mpg. How do I import these files into iMovie?
Q2: I just upgraded to Mavericks because of this advice (and it was about time), but I don't see any of these Services options when I right click. I have a mpg on my Desktop that is playable through Quicktime, etc., but won't go into iTunes, iMovie, or iPhoto...
According to the Apple official website, iMovie doesn’t support MPEG format. In other words, you are unable to locate your MPG files into iMovie directly. You need to find another way to perform the task. As we all know, the most compatible video codec for iMovie is AIC, then transocoding MPEG(MPG) files to AIC with a third party program is an easy way to edit MPG videos in iMovie.
To fulfill your task, you can just get Brorsoft’s Video Converter for Mac, a powerful video converter, editor and player.
