Changing a video into a novel involved copyright issues and required permission from the video copyright owner. Changing a video may involve copyright disputes, so it's best to contact the video copyright owner first to understand their copyright policies and requirements to ensure that the adaptation is legal. Adapting a video and adapting it into a novel were two different things. Changing a video could lead to copyright disputes because it might change the content of the original video to the point where it no longer meets the wishes of the copyright owner. An adaptation of a novel may complicate copyright issues because it involves the text of the novel, which may be subject to different copyright protection. Before any adaptation, you should understand the relevant copyright policies and requirements and ensure that the adaptation is legal. If you are not sure if the adaptation is legal, it is best to consult a professional first.
