Sora 2 Text-to-Video Pro

Sora 2 Text-to-Video Pro is OpenAI's premium text-to-video model. Describe any scene in natural language — AI renders it into a cinematic, high-resolution video with physics-aware motion, temporal consistency, and optional multi-character support. Compared to the standard version, Pro delivers higher fidelity output, broader resolution choices, and enhanced motion coherence for production-grade results.

Why Choose This?

  • Premium cinematic quality Higher fidelity output with enhanced detail, motion coherence, and richer scene composition than the standard version.

  • Physics-aware motion Understands contact, inertia, and momentum so objects, people, and environments move and interact believably.

  • Multi-character scene support Reference pre-defined character IDs to maintain consistent character identity across a single generation — no manual compositing required.

  • Broad resolution support Six output sizes spanning portrait and landscape orientations from 720p up to 1080p-class resolutions, suitable for social, cinematic, and broadcast workflows.

  • Temporal consistency Stable identities, minimal flicker and ghosting, and clean frame-to-frame transitions throughout.

  • Scalable duration Generate clips from 4 seconds up to 20 seconds to match your pacing and production needs.

Best Use Cases

  • Cinematic Storytelling — Render rich, narrative-driven scenes from detailed text descriptions.
  • Commercial & Brand Video — Produce premium-quality footage for marketing campaigns without a film crew.
  • Social Media Content — Generate portrait-format clips optimized for Reels, TikTok, and Shorts.
  • Documentary & Interview Style — Recreate specific camera aesthetics and era-accurate visual styles.
  • Multi-Character Scenes — Animate ensemble casts with consistent identity across the full clip.

Pro Tips

  • The more specific your prompt, the better the result — include camera style, lighting, era, mood, and character behavior.
  • Use portrait sizes (720×1280, 1024×1792, 1080×1920) for mobile-first platforms and landscape for cinematic or desktop formats.
  • Start with a 4-second generation at a lower resolution to validate your prompt before committing to longer, higher-resolution runs.
  • Character IDs must be created in advance — ensure they are saved and accessible in your account before adding them.

Notes

  • Only prompt is required; size, duration, and characters are optional.
  • Character IDs reference existing character profiles — this model does not create new character definitions.
  • Please follow OpenAI's usage policies when crafting prompts.
