I'm having an issue with importing videos into Movie Studio 17 (I'm on W7 64-bit) from my camera surveillance system. They are in MP4 format, but MS only sees them as audio files, not video. I have to run them through EaseFab and convert them to .mpg to be able to import them as both video and audio files, but this is a pain as that program is a trial version and only decodes 3 minutes of video. I shouldn't have to pay extra to use these files with this editor and MP4 files should be a non issue.
