Movie Gen

Movie Gen is a next-generation generative AI foundation model from Meta that covers multiple modalities including video generation, audio generation, and video editing. The system includes a 30 billion-parameter model for text-to-video generation (and image) and a 13 billion-parameter model for audio, enabling creation of short realistic videos (up to ~16 seconds) with synchronized sound effects and music. Beyond simple generation, Movie Gen supports personalization via a user’s image (allowing that person to appear in the video while preserving identity), editing of existing footage via text instructions (e.g., inserting objects or changing scene elements), and integration of audio tracks matching the content (e.g., background music, sound effects). Although released as research, Meta has noted that public developer access is not currently planned, and future rollout will focus on collaboration with creative and entertainment industry partners. Use-cases span creative content generation, filmmaking prototyping, advertising, immersive media, and internal tools for media production workflows, offering creators a new way to produce visual-audio content from simple prompts without needing extensive traditional filming or editing infrastructure.
