Sora 2 is the faster, exploration-oriented version of the Sora 2 architecture. For the highest final output quality, use Sora 2 Pro. Both models include integrated audio generation.
Faster exploration with OpenAI physics
Sora 2 is designed for the creative development phase — faster output speeds make it practical to explore multiple directions, test prompt variations, and iterate on a concept before committing to a final production render with Sora 2 Pro. The underlying Multimodal Diffusion Transformer (MM-DiT) architecture is shared with Sora 2 Pro, meaning physics-aware motion and synchronized audio generation are present in both. The distinction is output polish: Sora 2 may produce slightly less refined textures or rendering stability in complex scenes, but at the speed advantage that makes iteration practical.Capabilities
Physics-aware motion
Objects behave with physical accuracy — gravity, collisions, and spatial relationships render naturally throughout the clip.
Integrated audio generation
Generates synchronized dialogue, sound effects, and ambient audio alongside the video — no separate audio production needed.
4–20 seconds
A generous generation window — supports narrative sequences in a single generation.
Fast iteration speed
Faster than Sora 2 Pro — built for exploring directions quickly before committing to final-quality output.
Multimodal input
Accepts text prompts alone or combined with an image reference as the starting frame.
MM-DiT architecture
Multimodal Diffusion Transformer — the same foundational architecture as Sora 2 Pro with different quality/speed tradeoffs.

How to use
1
Open the AI Video Generator
Log into ImagineArt and go to the AI Video Generator.
2
Select Sora 2
Choose Sora 2 from the model dropdown.
3
Write your prompt
Describe the scene, camera behavior, audio environment, and motion. Include physics-heavy actions for the strongest results from the physics engine.
4
Set duration and resolution
Choose your clip length (4–20 seconds) based on your needs.
5
Generate and iterate
Use the faster generation speed to explore multiple prompt directions. When you find the right approach, switch to Sora 2 Pro for the final render.
Prompting tips
- Use it for direction testing — Generate 4–6 variations of a scene at lower cost and faster speed to find the best approach before using Sora 2 Pro for the final.
- Include audio context explicitly — “The scene opens with rain sounds and distant thunder, building to a dramatic climax” guides the integrated audio generation effectively.
- Physics descriptions work well — “A ball rolls down a ramp, bounces off the floor twice, and comes to rest” will produce physically accurate behavior.
Example prompts
A father and young daughter walk through a field of sunflowers at golden hour. Wide shot panning slowly right. Gentle wind rustling leaves. Warm, emotional atmosphere. 15 seconds.
POV shot of a kayaker navigating rapids. Water churning realistically, paddle splashing, rush of the river audible. Exciting and dynamic. 12 seconds.
