Why Blur Faces in Videos?

People often blur faces in videos to protect individual privacy and maintain confidentiality, particularly in sensitive situations or when featuring minors. By obscuring faces, creators can prevent the unauthorized use of personal images and help shield individuals from potential harassment or unwanted attention.

Additionally, blurring faces can shift the audience's focus away from the individuals and onto the main content of the video, such as events, products, or actions. This practice allows creators to convey their messages effectively while ensuring the privacy and safety of those featured.
