Free OpenAI Sora 2 Prompt Generator: Audio & Physics
Sora 1 was a demo. Sora 2 is a studio. The Promptsera Script Builder creates professional "Storyboard Prompts" optimized for Sora 2 and Sora 2 Pro. We structure your ideas into the four layers OpenAI's model demands: Visuals, Camera, Physics, and Audio.
Auto-formats dialogue blocks (e.g., `Character: "Hello"`) so Sora 2 syncs lip movement perfectly.
Injects logic keywords to ensure objects collide, bounce, and break realistically (unlike Veo).
Structures prompts to seamlessly blend your uploaded "Cameo" selfies into the generated scene.
Create Your Sora 2 Storyboard
Describe your scene. Select "Sora 2 Pro" for 25-second extended clips or "Standard" for fast generation.
Sora2 Video Prompt Generator
Create shot-list prompts with camera grammar, physics, and audio cues.
Sora2 Video Prompt
Optimized for: Sora iOS App, ChatGPT Pro, and the OpenAI API (`sora-2-pro`).
Sora 2 vs. Sora 1: The "Audio" Revolution
Released in late 2025, Sora 2 changed the game by introducing Multi-Modal Generation. While Sora 1 could only generate silent video, Sora 2 generates pixels and audio waveforms simultaneously.
This means you can no longer just describe the visual. You must describe the Soundscape. The Promptsera Generator adds a dedicated `[Audio]` layer to your prompt, ensuring that if a car crashes visually, the sound of "crunching metal and shattering glass" is generated in perfect sync.
Head-to-Head: OpenAI Sora 2 vs. Google Veo 3.1
Which model should you use? Our data shows distinct strengths for each.
| Feature | OpenAI Sora 2 | Google Veo 3.1 |
|---|---|---|
| Best Use Case | Narrative & Physics. Complex interactions (e.g., a ball breaking a window). | Cinematography. Beautiful lighting, drone shots, and B-Roll. |
| Audio | Lip-Sync Dialogue. Characters can speak specific lines. | Ambient Sound. Great background noise, weak dialogue. |
| Social Features | Cameo. Put your own face/body into the video via the App. | YouTube Shorts. Optimized for 9:16 viral content. |
Strategy: The "Storyboard" Prompt Structure
OpenAI's official guide recommends breaking prompts into distinct beats. Our tool automates this structure:
1. The Establishing Shot (0:00-0:05)
Wide angle, 24mm lens. A cyberpunk market at night. Neon rain. [Audio: Distant sirens and heavy rain on pavement].2. The Action Beat (0:05-0:15)
Medium shot. A robotic vendor hands a glowing chip to the camera. [Physics: The chip has weight, the hand servos whir]. [Dialogue: "This is the last one."]How to Use the Sora 2 Prompt Generator
- Set the Physics Logic: Choose "Realistic" for documentaries or "Surreal" for dream sequences. Sora 2 adheres strictly to this setting.
-
Input Dialogue (Optional):
If you want characters to speak, type their lines in the Dialogue box. Our tool formats it as
Character: "Line"for the API. - Generate & Copy: Paste the result into the Sora iOS App or the ChatGPT Pro interface.
Frequently Asked Questions
Is Sora 2 free to use?
Sora 2 has a free tier with daily limits on the iOS app. For unlimited generation and the Sora 2 Pro model (which supports 1080p resolution and 25-second clips), you need a ChatGPT Pro subscription.
How do I use the "Cameo" feature?
In the Sora App, upload a 3-second video selfie. Then, use our generator to create a prompt like [Cameo: User] walking on Mars. The model will replace the protagonist with your likeness while maintaining lighting consistency.
What resolution does Sora 2 support?
The standard model supports 720p (1280x720). The Pro model supports up to 1024x1792 (Vertical) or 1920x1080 (Horizontal). Always specify aspect ratio in your prompt (e.g., --ar 16:9).
