The best and easiest way to protect videos or other digital materials that feature student interactions is to only share them within the context of those students' originating course section. Canvas allows you to flexibly share content with students, while offering peace of mind when it comes to digital file sharing and student privacy. So long as access to materials is limited to only students in their class section, FERPA does not limit or prevent video use and does not require obtaining a written consent.
Some instructors choose to leverage media distribution systems for course content, though this is not advised. If access to recordings featuring students might not be limited to students in the class section, instructors must plan the recordings accordingly to remove personally identifiable student information. Instructors must make sure not to show students who are asking questions or refer to the students by name. If sharing live class videos outside of Canvas, avoid repeating student names in the recording (de-identifying the students removes the need for a specific consent from each student in the recording). If a student appears on camera, their identity must be either edited out or a written consent must be obtained - otherwise, the recording should not be distributed.
Because student presentations make it difficult to de-identify the student, the instructor should obtain a consent from the student making a presentation. Click here for a sample consent and release form.
