Sora 2 is a new-generation video and audio generation model launched by OpenAI. It can transform text or images into high-quality, realistic videos and simultaneously generate sound. Official descriptions state that its core positioning is an advanced video and audio creation tool for filmmakers, content creators, and developers, with improvements over the previous generation in motion realism, visual detail, audio synchronization, and precise control of scene composition, style, and dynamics.
In terms of main capabilities, the materials list the following features:
Realistic physics simulation: Sora 2 can model gravity, buoyancy, and motion dynamics to generate believable action performances, such as gymnastics, paddleboard backflips, and figure skating triple jumps. Officially, its physical naturalness is said to be superior to competitors.
20-second continuous generation: A complete 20-second clip can be generated in a single pass without manual stitching. Officially, its duration is said to exceed Veo 3's typical 8-second limit by more than 2.5 times, facilitating smoother storytelling.
Cameos personal appearances: You can insert your own image or someone else's and maintain accurate face, voice, and actions to create personalized videos. The materials state that this capability is unavailable in Veo 3.
Native audio and dialogue generation: Natively generates synchronized dialogue, ambient sound, and music, with lip movements matching the voice when characters speak.
Multi-shot world consistency: Maintains consistency of characters, objects, and environments across multiple shots and camera angles. Officially, its world continuity is said to be superior to the more fragile character continuity approach in Veo 3.
Multi-style mastery: It can cover a variety of visual styles such as realism, anime, and surreal art. Officially, it is said to perform outstandingly in non-photorealistic rendering.
In terms of usage, the materials provide a three-step process:
- Choose text-to-video or image-to-video mode. Image-to-video requires uploading an image; text-to-video requires starting with a clear and detailed prompt.
- Upload media (optional) and enter a precise prompt, set the aspect ratio (16:9 or 9:16) and other parameters.
- Submit the request to generate a video, preview the high-definition result, and then download it.
Applicable scenarios include film creation, content creation, storytelling, and video production that requires personalized characters to appear on screen. In terms of limitations, the materials do not provide details such as pricing, free quota, specific resolution specifications, a list of supported languages, commercial licensing terms, API access methods, or supported platforms; the comparisons with competitors and effect descriptions all come from official self-statements.
In the FAQ section, it is mentioned that users can learn about content such as 20-second continuous clips, realistic physics, Cameos, native audio, and multi-shot consistency, but the materials do not provide specific answers to these questions.
