Meta has introduced Movie Gen, an artificial intelligence system that creates high-resolution videos from text. Movie Gen is capable of customizing videos using reference images and modifying existing videos with textual instructions. The system also generates cinematic audio synchronized with the video. Tests demonstrate that Movie Gen surpasses similar systems by OpenAI and Runway in terms of video quality and customization and editing capabilities. The potential applications of Movie Gen are vast, including entertainment, advertising, research, and education. However, ethical challenges arise, such as the creation of deepfakes and the misuse of personal data. Meta is collaborating with other companies and organizations to address these challenges and promote the responsible use of Movie Gen.
