A collection of videos generated through our physics-first approach, compared to open-source (Mochi) and closed-source (Pika) generative models.
Videos comparing Saturn's physics-injected pipeline with Mochi and Pika.
"Block of cheese slides against the metal cheese grater"
Pika
That's just not how grating cheese works...
Saturn
We get the motion correct, and some cheese appears to be grated.
"Bike leans against the rough brick wall"
Mochi
The bike is leaning THROUGH the brick wall, the handle clips the wall. Towards the end of the video, some small abheration appears on the bike's wheel.
Saturn
Slightly different angle showing the entire bike, which keeps its form consistently throughout. The bike firmly leans against the wall without clipping it.
"Microfiber cloth rubbing water streaks from glass"
Pika
The surface looks like it has grooves rather than water. When the microfiber cloth wipes the glass, no visible liquid traces are seen but the grooves subtly change in form.
Saturn
We can clearly see the water droplets in the glass and when the fiber goes over the wet portion we see glass slowly being cleaned.
"Cymbal clashing with wooden drumstick"
Pika
The cymbal is flopping around without any apparent force being applied to it. Furthermore, when the drumstick seems to make contact with the cymbal, the way the force is propagated is unnatural.
Saturn
The drumstick does make contact with the cymbal and the force propagation is reasonable, albeit the metal looks stiffer than in most drumkits
