For my work, I will be creating database tutorials and guides. There is sensitive information in the database that I would want to blur out in screencasts. Does SnagIt allow you to blur out parts of a video or do I need to get Camtasia for that? Can Camtasia video files be embedded in an online LMS like Talent LMS? Lastly, are the prices shown for the products a one-time price or is it an annual thing?
