Google AI introduces Lumiere! Their video and image Generation Platform!

Introduction

Lumiere is an innovative project by Google Research that introduces a Spacetime diffusion model capable of generating the entire temporal duration of a video at once, supporting real-time video generation. This represents a significant advancement compared to existing video models that synthesize distant keyframes followed by temporal super-resolution, a method that struggles to maintain global temporal consistency.

If you're new to the channel, my name is Ben Silverman, and I focus on making AI more accessible to creatives, empowering them to scale and focus on what they do best. I've put together an AI toolbox that acts like my second brain, containing all the knowledge I've accumulated so that others don’t have to spend a year diving down various rabbit holes.

Lumiere can generate full frame rate, low-resolution videos by processing multiple space-time scales. It leverages both spatial and temporal downsampling and upsampling. It has similarities with existing tools, but its results look amazing, as showcased in their research paper. Let’s explore what Lumiere offers:

Text-to-Video Conversion

Lumiere converts text prompts into videos, producing impressive results. For example, a text prompt of "a knight riding a horse in the countryside" or "a panda" generates highly realistic animations. Examples like "toy poodle dog riding a penny board outside" and "a cat playing the piano" demonstrate the model's capability to produce creative and detailed videos.

Image-to-Video Transformation

Lumiere can transform input images into videos based on prompts. An example includes a photo of a panda turned into a video where the panda eats bamboo on a rock. Similarly, a photo of relaxed ocean waves is animated to show moving waves. This feature allows users to breathe life into static images.

Stylized Generation

Using a single reference image, Lumiere can generate videos in a target style. For instance, providing an image reference alongside a prompt like "a girl with a beanie dancing" results in videos that animate stickers in different styles.

Video Stylization

This feature uses off-the-shelf text-based image editing methods for consistent video editing. A source video can be transformed into various styles, such as wooden blocks, colorful toy bricks, or flowers, maintaining the video’s thematic integrity throughout.

Cinemagraphs

Lumiere allows for the creation of cinemagraphs by animating specific parts of an image. For example, the smoke of a train in a still image can be animated to move, adding a dynamic element to an otherwise static photo.

Video In-Painting

One of Lumiere’s most impressive features is video in-painting. Like Adobe's upcoming "Fast Fill," this technology can mask portions of a video and generate content to fill in these masked zones seamlessly. This can be used creatively, like changing a balloon’s color or adding new elements to a scene.

Conclusion

Google’s Lumiere project represents the forefront of AI-driven video and image generation. Their focus on AI for 2024 aims to develop the best models out there. The key excitement lies in when these tools will become available for everyone to explore and utilize.
