Sora OpenAI’s Text to Video Generation Model

Context: 

Recently, OpenAI, the creator of  chatbot ChatGPT, has introduced a Generative Artificial Intelligence (GenAI) model named Sora OpenAI.

About Sora OpenAI: 

Sora OpenAI in Japanese means sky, an imagery that evokes ‘limitless creative potential’. 

• SORA OpenAI is a diffusion based AI model developed by OpenAI, specialising in transforming textual prompts into vivid and realistic video scenes. 

• • It leverages a diffusion model and transformer architecture to understand and simulate the physical world in motion.
• It is currently unavailable for general use as OpenAI is focusing on implementing safety protocols and gathering feedback from visual artists and filmmakers.

• Features of Sora OpenAI

• • Text to Video Capabilities: It can create videos lasting up to one minute, ensuring exceptional visual quality while following user instructions. 
  • Generating Complex Scenes: It crafts elaborate scenes featuring multiple characters, diverse motions, and precise details of both the subjects and backgrounds. 
  • Create Dynamic Impressions and EngAgeing Characters:  Proficient in comprehending real-world object functionalities and accurately interpreting instructions.
  • Multishot Avatar Production: It showcases the ability to generate multiple shots within a single video, maintaining consistency in characters and visual style.

• • Filters : To block prompt requests that mention violent, sexual or hateful language, as well as images of well-known personalities.

Limitations of Sora OpenAI

• Limited Dataset: If the dataset lacks certain types of scenes or visual variations, it may produce videos that lack realism or exhibit strange artefacts.
• Complex Scenes: Generating realistic videos becomes increasingly challenging when scenes involve complex interactions, intricate details, or dynamic elements.
• Temporal Consistency: It might encounter difficulties in ensuring smooth transitions and coherence between consecutive frames, leading to jarring or unnatural-looking sequences. 
• Real-time Performance: Depending on the hardware and computational resources available, generating videos with Sora in real-time may pose challenges. 
• Ethical Considerations: In accurately discerning between real and manipulated content could exacerbate these concerns if not carefully addressed. 
• Domain Specificity: Its performance may vary across different domains or types of videos. It may excel in certain contexts while struggling in others.
