Video manipulation is a digital process that involves altering or modifying video images to produce a desired effect. Its roots can be traced back to the 1950s when it required manual tape cutting and splicing. Over time, it has evolved with technologie[2] advancements, such as the video cassette recorder, digital editing systems, and leading editing software like Adobe Première[4] and Apple’s Final Cut Pro. In recent years, it has seen a significant leap with the introduction of deepfake[3] technology, which uses intelligence artificielle[1] to create hyper-realistic fake videos. The technology can be used creatively, but it also poses serious threats in the realms of politics and news, making it a subject of regulation and policy debates globally. The key challenge lies in balancing the freedom of information with the potential harm from the spread of fake and misleading content.

Définitions des termes
1. intelligence artificielle.
1 Artificial Intelligence (AI) refers to the field of computer science that aims to create systems capable of performing tasks that would normally require human intelligence. These tasks include reasoning, learning, planning, perception, and language understanding. AI draws from different fields including psychology, linguistics, philosophy, and neuroscience. The field is prominent in developing machine learning models and natural language processing systems. It also plays a significant role in creating virtual assistants and affective computing systems. AI applications extend across various sectors including healthcare, industry, government, and education. Despite its benefits, AI also raises ethical and societal concerns, necessitating regulatory policies. AI continues to evolve with advanced techniques such as deep learning and generative AI, offering new possibilities in various industries.
2 Artificial Intelligence, commonly known as AI, is a field of computer science dedicated to creating intelligent machines that perform tasks typically requiring human intellect. These tasks include problem-solving, recognizing speech, understanding natural language, and making decisions. AI is categorised into two types: narrow AI, which is designed to perform a specific task, like voice recognition, and general AI, which can perform any intellectual tasks a human being can do. It's a continuously evolving technology that draws from various fields including computer science, mathematics, psychology, linguistics, and neuroscience. The core concepts of AI include reasoning, knowledge representation, planning, natural language processing, and perception. AI has wide-ranging applications across numerous sectors, from healthcare and gaming to military and creativity, and its ethical considerations and challenges are pivotal to its development and implementation.
2. technologie. La technologie, dérivée des mots grecs signifiant artisanat et connaissance, est un terme général qui désigne les outils, les machines et les systèmes mis au point par l'homme pour résoudre des problèmes ou atteindre des objectifs. Née avec des outils primitifs comme les haches de pierre et la découverte du feu, la technologie a évolué de manière significative tout au long de l'histoire de l'humanité. Elle a joué un rôle déterminant à différentes époques, depuis l'invention de la roue et des systèmes d'irrigation avancés dans les civilisations anciennes jusqu'à la naissance des universités et de la presse à imprimer au cours des périodes médiévale et de la Renaissance. La révolution industrielle du XVIIIe siècle a marqué un tournant important dans la production de masse et l'innovation, donnant naissance aux technologies modernes telles que l'électricité, l'automobile et les plates-formes de communication numérique. Aujourd'hui, la technologie fait partie intégrante de divers aspects de la vie et de la société, stimulant la croissance économique et les changements sociétaux, tout en suscitant des préoccupations en matière de sécurité, de respect de la vie privée et d'incidences sur l'environnement. L'avenir de la technologie devrait apporter encore plus de progrès, avec l'essor de l'intelligence artificielle qui devrait avoir des implications significatives sur le marché du travail.

Manipulation vidéo is a type of media manipulation that targets digital video using video processing et video editing techniques. The applications of these methods range from educational videos to videos aimed at (mass) manipulation and propaganda, a straightforward extension of the long-standing possibilities of photo manipulation. This form of computer-generated misinformation has contributed to fake news, and there have been instances when this technology was used during political campaigns. Other uses are less sinister; entertainment purposes and harmless pranks provide users with movie-quality artistic possibilities.
