Copyright under English law is primarily established under the Copyright Designs and Patents Act 1988. Copyright can extend to protect videos and images taken by you on your devices.
In such circumstances, these videos and images are protected 70 years from the end of the life of the taker. This can function to protect photographs and videos that you have taken from use by third parties. By enforcing your copyright ownership you can control who has the right to use and edit the images and/or footage in question. This is usually in the form of a cease and desist letter notifying the third party of your ownership of the material whilst asking that they stop usage as soon as possible.
