̟Video files on an iPhone 3GS may not import properly using the Studio 14 Importer. These files can still be used in Studio 14 using the following method.
Step 1: Move the file(s) to a location on your local hard drive. The location doesn't matter, it is just important that you can find it later.
Step 2: In the Edit mode of Studio 14, open the desired file. You can do this by clicking the "Select video files from a different folder" icon in the Album and then browse for the file to open. Once opened, the file will be available for use in the Album.
