Q & A
What is the name of the new open-source AI video model mentioned in the transcript?
-The new open-source AI video model mentioned is called 'Story Diffusion'.
What is the significance of Story Diffusion in terms of character consistency?
-Story Diffusion is significant because it not only maintains facial consistency but also ensures consistency in clothing and body type across different shots and scenes, which is crucial for creating believable characters.
How does Story Diffusion handle the creation of AI comics?
-Story Diffusion creates AI comics by generating a series of images for a sequence, ensuring consistency in terms of face and clothing, then predicting the movement between those images and animating them using a motion prediction model.
What is the typical length of the videos created by Story Diffusion?
-The videos created by Story Diffusion can be up to 30 seconds long, with a high level of character consistency and adherence to reality and physics.
How does Story Diffusion compare to Sora in terms of video resolution?
-There is no specific information on the resolution of videos generated by Story Diffusion in the transcript. However, the previews on their website are rendered at 832 pixels by 832, which could be upscaled to at least 2K definition with an AI upscaler.
What is the main advantage of Story Diffusion in terms of computational resources compared to Sora?
-Story Diffusion used only eight GPUs for training its model, whereas Sora used 10,000 GPUs, which is 1250 times more computational power. This makes Story Diffusion significantly more efficient in terms of training and running costs.
How does Story Diffusion ensure consistency across different images?
-Story Diffusion uses consistent self-attention, which enhances the consistency of different generated images by ensuring that each one shares certain attributes or themes, making them visually coherent when viewed as a series.
What is the process of 'story splitting' as used by Story Diffusion?
-Story splitting involves breaking down a story into multiple text prompts, each describing a part of the story. These prompts are processed simultaneously to produce images that depict the narrative in sequence, ensuring continuity and coherence in the generated images.
How does Story Diffusion handle the animation of diverse scenes?
-Story Diffusion effectively animates diverse scenes by correctly identifying and animating moving objects and characters while leaving static objects inanimate. It also applies camera movements and understands zooming functions to create a natural and fluid animation.
What are the limitations of Story Diffusion when it comes to character consistency?
-While Story Diffusion performs well in maintaining character consistency, there are still minor inconsistencies that can be noticed upon close inspection, such as changes in the length of a character's tie or slight variations in facial markings.
How does Story Diffusion's approach to AI video generation compare to existing models?
-Story Diffusion shows a significant evolution in character consistency and the ability to create scenes that make realistic and cohesive sense. It is considered a step forward in AI video generation, offering more natural and fluid animations compared to existing models.
