What is Sora?

Sora is an open AI text-to-video model that creates realistic and imaginative scenes from text descriptions. Sora is one of the generative AI models that takes text descriptions as input and generates videos of varying quality and dimensions.

According to research shared by Open AI, Sora is a model that can transform static noise into different steps to create realistic videos.

The Sora tool is trained to work with images and videos, which are broken down into smaller pieces of data called "patches."

For instance, if you want to create a video of fashionable women walking along a Tokyo street, as shared by OpenAI, the resulting video would look like:

However, the complete description that was provided as a text prompt was:

A stylish woman walks down a lively street in Tokyo, surrounded by warm, glowing neon lights and animated city signage. She exudes confidence and ease as she strolls along, wearing a stunning ensemble consisting of a black leather jacket, a long red dress, black boots, and carrying a black purse.

She completes her look with sunglasses and bright red lipstick. The street is damp from recent rainfall, creating a reflective surface that multiplies the colorful lights. Many pedestrians walk around, adding to the bustling scene.

As simple as it sounds!

But what are the technologies behind it, and how exactly does it work? Let’s understand that in our next section.

Technologies Used in Sora

Sora AI uses a combination of advanced AI technology and generative AI tools to understand and create video content. This includes:

• Diffusion Models

Diffusion models enable Sora to generate more precise videos and images by gradually adding and removing noise from visual data. This allows Sora to create coherent and clear visual content from a cluttered starting point.

• Spacetime Patches

Sora breaks down the videos into small spacetime patches. These patches are the manageable video pieces that let Sora quickly analyze, learn, and handle videos of varied resolutions, durations, and aspect ratios. 

• Transformer Architecture

Sora uses an architecture similar to the transformers used in language processing for GPT models to handle video data. This allows Sora to comprehend both the spatial and temporal aspects of videos and to make sense of how scenes and objects change over time.

How Does Sora Work?

Sora utilizes advanced machine-learning techniques to create videos from text descriptions. Using Sora, the video creation process comprises a series of steps. 

• Receiving a Text Description

The process begins with a user providing a text prompt of the video's characters, style, setting, and other essential elements. This prompt could be anything like an old woman playing the piano.

• Turning Videos Into Patches

Sora begins the process of breaking down an existing video into spacetime patches. This process involves the videos compressing into lower dimensional space and then breaking it into small and manageable patches that represent different elements and moments of the video.

• Comprehending From Patches

By analyzing these created patches, Sora learns the dynamics and patterns of the various objects and scenes. It understands how an old woman can be infused into the scene and how piano keys might look to be shown as a realistic performance given by an old lady.

• Generating New Patches

With the help of the given text description, Sora uses its understanding to create new patches that match the prompted scene. It imagines what the patches for "an old lady playing the piano" should look like while considering the old women, lighting, and the whole setup.

• Assembling the Video

Finally, Sora combines these created patches to create a coherent video. This ensures that the motion is streamlined and smooth, and the natural transition of the scenes and the overall video matches the initial description both contextually and visually. Also, Sora automatically enhances the video quality by adding effects, music, and other elements to provide the user with a desired video outcome.

In a nutshell, Sora AI is designed to make video generation easier by breaking down complex tasks into smaller, more manageable sections or patches. It then learns from vast amounts of video data and uses this knowledge to create new content based on textual descriptions. This innovative approach enables Sora AI to produce visually impressive videos that perfectly align with the user's creative vision.

Turning Visual Data Into Patches - 

Sora has drawn inspiration from the Large Language Models to create visual patches that can be used to train generative models for various types of images and videos. These patches are highly effective and scalable.

To create the patches, the videos are first compressed into a lower latent space before being turned into patches at higher levels.

Spacetime Latent Patches - 

Sora uses a compressed input video to extract spacetime patches that transform into a patch-based representation. This representation helps Sora create videos and images of different durations, resolutions, and aspect ratios. 

Scaling Transformers for Video Generation - 

Sora is a transformer that takes noisy patches as input and predicts clean patches. This diffusion mode has impressive scaling properties in different domains.

Sampling Flexibility - 

Sora can create videos in any aspect ratio, including 1920x1080 and 1080x1920, making it easy to create content for a variety of devices.

Sora can create intricate scenes with several characters, precise motion types, and accurate details of the subject and the background. The model not only comprehends the user's prompt but also has an understanding of how these elements exist in the real world.

Language Understanding -  

Text-to-video generation systems require a large number of videos with matching text captions. Sora employs the re-captioning technique from DALL-E 3 to the generated videos, resulting in a highly descriptive captioner model. This model is then used to create text captions for all of the videos.

Animating DALL-E Images - 

Sora's video creation feature is amazing, even allowing image input. See an example of DALL-E2 and DALL-E3 image-based video generation below.
