Meta Feature Will Allow To Make AI-Generated Video From Text

Meta, the parent company of Facebook, has launched Make-A-Video, an artificial intelligence (AI) program that allows users to create a video from a text description or image prompts. Make-A-Video is not yet available to the general public. However, Meta has provided a sign-up form that people can use if they want to try it in the future. On Make-A-announcement Video's page, Meta displays examples of videos generated from text, such as "a young couple walking in heavy rain" and "a teddy bear painting a portrait," as well as demonstrating Make-A-ability Video's to animate a static source image. A still photo of a sea turtle, for example, can appear to be swimming after being processed by the AI model. Meta Debuts In The Field Of AI Generated Video With Make-A-Video The key technology behind Make-A-Video—and why it arrived sooner than some experts expected—is that it builds on previous work with text-to-image synthesis, which is used with image generators like OpenAI's DALL-E. In July, Meta announced its own text-to-image AI model called Make-A-Scene. Instead of training the Make-A-Video model on labeled video data (for example, captioned descriptions of the actions depicted), Meta used image synthesis data (still images trained with captions) and unlabeled video training data to teach the model about the location of a text or image prompt in time and space. Then it can predict what will happen after the image and show the scene in motion for a short time. "Using function-preserving transformations, we extend the spatial layers at the model initialization stage to include temporal information," Meta wrote in a white paper. "The extended spatial-temporal network includes new attention modules that learn temporal world dynamics from a collection of videos." Meta Debuts In The Field Of AI Generated Video With Make-A-Video Meta recognizes that the ability to create photorealistic videos on demand poses some social risks. According to Meta, all AI-generated video content from Make-A-Video includes a watermark to "help ensure viewers know the video was generated with AI and is not a captured video." Text-to-still-image AI systems, such as DALL-E 2, Stable Diffusion, and competing projects from Google, Meta, and others, have advanced rapidly in the last year. Meta now appears to have won the race to extend AI-powered content creation to videos.
