So basically what i want to achieve is making the default text have an outline and making the outline black. What im referring is how to change it in the TitlesAndText file located in Movie Studio Platinum 17.0\OFX Video Plug-Ins\TitlesAndText.ofx.bundle\Contents\Resources
Those files are xml files. Unless you're competent in editing xml files you should leave them alone. Why not just make your changes to the default preset and save it as a custom one?
