It is not illegal to record someone without their consent in a public place if they are visible and audible, especially if they don't have reasonable expectations of privacy. But in a private setting, such as a bathroom or changing area, recording someone without their knowledge is illegal.
Having a video consent form signed before the filming process begins prevents the person from coming to you saying they want any usage of their image to be removed from the project. In essence, a video release form helps to avoid any further legal complications that could arise in the future.
To be valid, consent must be voluntary, informed, specific, current, and given by a person with capacity. Unless otherwise indicated, consent can be express or implied, written or verbal.
