Google unveiled its latest artificial intelligence (AI) model, Lumiere, last week. The new AI model is a multimodal video generation tool that can generate 5-second-long videos. It supports both text-to-video and image-to-video generation and joins existing AI models such as Runway Gen-2 and Pika 1.0. As per Google, Lumiere uses a Space-Time U-Net (STUNet) architecture that innovates how motion occurs in an AI video, making it appear realistic. The platform is not open to the public as of yet. In an accompanying preprint paper, the research team behind Lumiere explained that the major innovation in motion comes from creating the video in a single process instead of putting together still frames. Due to this, both the spatial (the objects in the video) and temporal (how things move around in the video) aspects of the video generation are created simultaneously. For the layperson, this results in perceiving motions as they occur in nature. To achieve this, Lumiere generates a larger number of 80 frames instead of Stable Diffusion’s 25 frames. “By deploying both spatial and (importantly) …
