Sora

What's Sora?

Sora is OpenAI's first text-generated video model, capable of generating videos up to 60 seconds long based on textual commands, including multi-angle camera switches, complex scenes, and vivid character expressions.Sora is based on a diffusion model, and is capable of generating videos up to one minute long, maintaining visual quality and a high degree of reproduction of user input. In addition to creating videos from scratch, Sora can generate animations based on existing still images, or extend and complement existing videos. It can handle visual data of different durations, resolutions and aspect ratios.

Key Features of Sora

• Text to Video ConversionSora's video content can be generated by simply typing in a text description, significantly lowering the barriers to video production.
• Image and video cues: Sora can use an existing image or video as input to perform a variety of editing tasks, such as creating perfectly looping videos, animating still images, expanding videos forward or backward, and more.
• Animated DALL-E images: Can generate video from DALL-E 2 and DALL-E 3 images.
• Style presets: Users can define a video style, and Sora can generate a video that matches that style.
• Remix Features: Users can modify certain objects in the video through natural language descriptions, such as changing an old house into a fantasy castle.
• Recut Recut: Users can delete clips they don't like, and Sora will automatically generate new footage that fits seamlessly into the original video.
• Storyboard Features: Users can create descriptions for multiple keyframes to make the articulation between each frame more natural, which is suitable for short videos or movie and TV works that require logical coherence.
• Blend Mixing Functions: Supports users to mix two videos to generate a brand new video.
• Loop infinite loop function: Users can join videos end to end to create a seamless looping video effect suitable for social media video creation.
• Physical simulation vs. real-world simulation: Sora tries to simulate real-world physics rules when generating videos, such as the reflection of light or the movement of objects, although it may not be perfect in some complex scenes.
• Video Extension and Optimization: Sora supports generating videos from scratch, allowing existing videos to be expanded to fill in missing frames or add new content.
