When high-quality images produced by generative AI first began to appear in 2022, they had an undeniable wow factor. The creative process involved little more than entering a text description and waiting for the AI system to produce a relevant image.
At that time, an obvious question was when AI-generated video would catch up. Indeed, various groups have since unveiled AI systems that automatically generate video, but always with important limits to their length, the type of realistic motion they could produce and to their overall quality.
One way to solve these problems is with brute force. But this computing power significantly increases costs. So the search has been on to find more efficient and more capable approaches.
Now Google says it has developed just such a technique that dramatically improves the efficiency of video synthesis. Omer Bar-Tal and colleagues at Google say their new system, called Lumiere, produces videos ...
