Privacy is absolutely a concern. To ensure compliance with FERPA, you must not share (outside of class) videos that contain personally identifiable information of students unless you have secured written consent from the student. While you will obtain consent from your students to record them, it's also important to protect their privacy as much as possible. Of course, you should also consider your own privacy when posting video online, just as you avoid over-sharing on social media. See the privacy settings for popular hosting sites below.
Protecting your privacy and the privacy of your students in a university setting allows students to learn and grow as a professional in their future field of choice without having to worry about possible negative consequences. Restricting access to the content and deleting the content at the end of the semester are 2 methods, documented below, that can help you protect your privacy.
This EDUCAUSE article explains more about why keeping your student information private is important.
