This AI technique demonstrates absolutely insane video transformation capabilities, going beyond mere image-to-video generation. It offers advanced features like plausible motion, dramatic lighting changes, and full spatiotemporal attention, all while being free and highly efficient.
This AI technique offers impressive video transformation capabilities, demonstrating functionalities that are significantly advanced.
The technique is based on an image-to-video model that is freely available, allowing users to specify a starting image for video continuation.
The model can generate plausible motion for subjects like ducks and incredibly realistic waving and smiling children.
It accurately handles dramatic lighting changes and manages complex camera movements, requiring the AI to imagine the surrounding world.
The model effectively handles interaction with the environment and simulation during actions like running.
The video transformation can be combined with an incredible control model to reimagine videos with semantic and stylistic alterations.
The technique allows for semantic changes, such as transforming athletes with fencing swords into Master Roshi with golf clubs or lightsabers.
Users can apply stylistic transformations like 'starry night-ifying' themselves and their environment or converting a muddy scene into a winter wonderland with falling snow.
It enables transforming into different characters, like video game characters, and adjusting the lighting of a generated scene with a single prompt.
The system generates 5 seconds of video in 2 seconds on one H100 graphics card, operating faster than real-time consumption.
The underlying paper reveals the use of a 1:192 spatiotemporal compression variational autoencoder with 128 latent channels, efficiently squashing video data.
Operating at a 1:8000 pixels-to-tokens ratio, which is 4x fewer tokens than typical setups, it significantly reduces the cost of attention for full spatiotemporal attention.
The model uses less than 2 billion parameters before distillation, representing a modest size that usually implies modest performance, but here delivers great performance.
This incredible work is freely available to everyone, encouraging immediate experimentation.
We taught sand to think.
