Features

> Notice — Service Stability > > The Sora 2 family is being retired or has already been retired by its original provider. Until it is fully removed, the service is unstable: generations may fall back to alternative models without notice, results can differ from what this model used to produce, and the service can be temporarily unavailable. > > If you need an equally capable, stable alternative, we recommend Seedance 2: bytedance/seedance-2.0/image-to-video.

OpenAI Sora 2 Image-to-Video

Sora 2 Image-to-Video brings your images to life with OpenAI’s state-of-the-art video generation. Upload an image and describe the motion — watch as AI transforms your still photo into a dynamic, cinematic video with synchronized audio.

Why Choose This?

• Image animation Transform any still image into smooth, realistic video with natural motion.

• Physics-aware motion Learns contact, inertia, and momentum so objects move and collide believably.

• Synchronized audio Generates matching audio — ambient sounds, dialogue, and sound effects.

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

• Cinematic quality Natural camera movements, high-frequency detail, and professional-grade output.

• Flexible duration Generate videos from 4 to 20 seconds.

Parameters

How to Use

1. Upload your image — the still photo you want to animate.
2. Write your prompt — describe the action, motion, camera movement, and audio.
3. Set duration — choose 4, 8, 12, 16, or 20 seconds.
4. Submit — generate, preview, and download your video.

Pricing

Billing Rules

• Rate: $0.10 per second
• Duration options: 4, 8, 12, 16, or 20 seconds

Best Use Cases

• Photo animation — Bring still photos to life with realistic motion.
• Product showcases — Animate product images for dynamic marketing.
• Art animation — Transform illustrations and artwork into videos.
• Social media content — Create eye-catching animated posts from images.
• Storytelling — Build narratives from key visual moments.

Pro Tips

• Be specific about motion in your prompt: “The kitten pounces toward the yarn” beats “kitten playing.”
• Include audio cues in your prompt for better synchronized sound.
• Higher resolution source images produce better results.
• Describe camera movement if you want dynamic cinematography.
• Start with shorter durations to test your prompt before generating longer videos.

Notes

• Image and prompt are both required fields.
• Duration options: 4, 8, 12, 16, or 20 seconds.
• Please follow OpenAI’s usage policies: What images are permitted and prohibited in Sora-2

Related Models

• Sora 2 Text-to-Video — Generate videos from text prompts.
• Sora 2 Pro Image-to-Video — Premium quality with more resolution options.
