"I'm importing a mp4 file using Premiere Elements 12 on a Macbook Air running OS X 10.9.2. However, it doesn't appear to import, though a blank thumbnail appears in organizer. When I attempt to open the file, I get a missing codec error message. Help?"
Officially, Adobe stated that MP4 is supported by Premiere Elements 13/12/11/10. But the problem with MP4 is, when you plan to edit the MP4 file with Premiere Elements, you may be able to do this, but may be unable to. So what's the matter? Well, this depends on. The reason is that MP4 is a format container with different codecs. If your MP4 file codec isn't compatible with Adobe Premiere Elements, you will be unable to load them to Premiere Elements for editing or import without no sound or no video. In fact, there is an easy way to solve your problem. You just need to convert this MP4 video to other Premiere Elements friendly movie format like MOV, MPEG-2 or WMV.
Actually, it's not as difficult as you imagine.
