Features

Sora 2 Text-to-Video

Sora 2 Text-to-Video is OpenAI’s text-to-video model purpose-built for scenes featuring multiple distinct characters simultaneously. Describe the scene in natural language, reference your pre-defined character IDs, and the model renders a cohesive, temporally consistent video where every character looks and moves exactly as intended — no manual compositing required.

Why Choose This?

• True multi-character consistency Reference two or more character IDs in a single generation. Each character retains its unique appearance, proportions, and style throughout every frame.

• Natural-language scene control Describe interactions, environments, and actions in plain text. The model understands spatial relationships and character dynamics to produce believable compositions.

• Flexible aspect ratio support Choose between portrait (720×1280) and landscape (1280×720) orientations to match your target platform.

• Scalable duration Generate clips from 4 seconds up to 20 seconds in fixed steps, giving you full control over pacing and output cost.

• Production-ready output Delivers smooth, artifact-free motion suitable for marketing content, storytelling, game cinematics, and social media video.

Pro Tips

• Be specific about character positions and actions in your prompt for better spatial composition.
• Use portrait mode (720×1280) for mobile-first platforms and landscape (1280×720) for cinematic or desktop use.
• Start with a 4-second generation to validate composition and character rendering before committing to a longer duration.
• Ensure all referenced character IDs are valid and accessible in your account before submitting.

Notes

• Character IDs must be created and saved in advance — this model references existing character profiles and does not create new definitions.
• Only prompt is a required field; size, duration, and characters are optional.
• Complex multi-character scenes benefit from concise, clearly structured prompts.
