Although the act of filming a video at a public school itself is legal, the contents of the video may cause legal difficulties, states VideoMaker. Privacy and copyright concerns may render the video illegal.
Because they classify as public places, it is legal to shoot a video at public schools, as stated by VideoMaker. However, the people involved may consider it an invasion of their privacy and sue the person shooting the video. As such, it is a good idea to ask for their permission before shooting people at public schools. Likewise, the school may exercise its own rules about shooting and it's a good idea to consult the school administration beforehand.
If the video contains copyrighted material, legal challenges may arise regardless of location, adds VideoMaker. However, the Fair Use laws provide ways to avoid copyright claims if the video is for academic purposes, as stated in the 17 U.S. Code § 107.
