Key Features of SR-2
Discover what makes SR-2 stand out
World Model
Physics-Aware Video Generation
Built on world simulation technology, SR-2 generates videos where objects obey physical laws — natural gravity, realistic lighting, coherent motion, and accurate material properties.
Frame Control
Start Frame Reference
Upload an image as the start frame to define the opening visual and style. Guide the AI on exactly where the scene begins for controlled storytelling.
Flexible Duration
4, 8, or 12 Seconds per Clip
Choose the exact duration you need — from quick 4-second social clips to 12-second narrative sequences. Consistent quality throughout the entire duration.
Fast Iteration
Rapid Prototyping at 720p
SR-2 generates faster than SR-2 Pro, making it ideal for rapid iteration, prompt experimentation, and exploring creative directions before committing to a final render.
Getting Started
How to Use SR-2
Upload a Start Frame (Optional)
Upload an image as the start frame to anchor the visual style, composition, and mood of your video from the opening shot.
Describe Your Scene
Write a natural language prompt describing the action, mood, and camera movement. Select 16:9 or 9:16 aspect ratio and 4, 8, or 12 seconds duration.
Generate & Iterate
Click Generate to create your video at 720p. SR-2 is optimized for speed — iterate rapidly on prompts and references to find the perfect result.
FAQ About SR-2
We've answered the most frequently asked questions
SR-2 outputs at 720p and is optimized for faster generation and rapid iteration. SR-2 Pro supports up to 1080p with richer color depth and sharper textures, but takes longer to generate. Both support the same duration options (4, 8, 12 seconds).
Yes. You can use SR-2 for free on our platform — generate AI videos at no cost.
SR-2 outputs at 720p in 16:9 (landscape) or 9:16 (portrait) aspect ratios at 24 fps.
Yes. Upload an image as the start frame to anchor the visual style and guide the direction of the generated video. Text-only prompts also work.
SR-2 uses a world simulation model to understand physical laws. Objects exhibit natural gravity, momentum, and material behavior — making generated videos look physically plausible.
