“So I think the other interesting thing that we showed a slightly earlier, but also want to kind of reemphasize here is how dream machine is able to reason about the non-physical world as well. Even in cases where it's in entirely a scene of art, it is able to, first of all, do camera changes and also introduce like new concepts into the scene. By just using the model.”

Song: Compute Scale Replaces Years of Explicit Graphics and Physics Engineering
“What's really surprising to me is how a large scale of compute is Mostly all you need to capture a lot of the, like, intricate effects that people spend years to develop in, like, graphics and, you know, physics simulation community”
Song: Dream Machine Learned Physical Simulation and Lighting Without 3D Priors
“But what's really surprising about Dream Machine is that we almost did nothing with regards to these NERF datasets or have zero, three D priors into how the model works. But the model just by itself learns to kind of uncover these interesting physical aspects …”
Song: Dream Machine Spontaneously Generates Consistent Cinematic Cuts Without Prompting
“Even though we haven't really asked the model to do anything about it, the model is able to reason about the second shot being a cut of the first shot that happens to have the same things in the first shot. So this is curse definitely some kind of a non-trivia…”
Song: Strict Physics Simulation Cannot Solve Fictional or Artistic Video Generation
“If we were trying to reason about the world via the traditional kind of physics techniques, it is very difficult to kind of reason about things inside a totally fictional world. So I think this is something that more happens like inside our dreams rather than …”
Song: Video AI Models Learn Psychological Causality Beyond Basic Physics
“And this is possibly caused by this eye being very unnaturally looking, and this is some kind of a cause and effect that is, like, even harder to reason, like, strictly in the physics, but more delving into how just human psychology works. So I think the causa…”
