🎞️ Google Veo 3.1 — Image-to-Video (I2V) Model

Veo 3.1 I2V is Google DeepMind’s latest image-to-video generation model — an evolution of Veo’s cinematic foundation. It transforms a single still image or a pair of start & end frames into a high-fidelity 1080p motion sequence with natural movement, realistic lighting, and synchronized contextual audio.

Perfect for storyboarding, concept animation, and creative scene development, Veo 3.1 I2V captures the feeling of camera motion and environmental change while preserving your image’s style and composition.

🌟 Why it stands out

• 🎬 Cinematic Motion Generation Animates still images with realistic subject and camera movement — from subtle pans to sweeping transitions.

• 🪄 Frame Interpolation Supports single-frame animation and two-frame transitions — letting you morph from one image to another with fluid continuity.

• 🔊 Native Audio Support Adds synchronized ambient sound, dialogue, or music automatically aligned with visual motion.

• 🧠 Contextual Understanding Interprets both image content and prompt text to guide scene flow and atmosphere.

• 📐 High-Resolution Output Generates at 720p or 1080p, 24 FPS, and supports landscape (16:9) or portrait (9:16) aspect ratios.

⚙️ Key Parameters

• prompt — Describe motion or story context (e.g., “Slow dolly zoom on a city skyline as sunset light fades”).
• image — Provide a starting frame (JPEG / PNG / WEBP).
• lastFrame (optional) — Provide an ending frame to create an interpolation-style transition.
• durationSeconds — Choose video length: 4s, 6s, or 8s.
• resolution — 720p or 1080p.
• aspectRatio — Landscape (16:9) or Portrait (9:16).

🚀 How to Use

1. 🖼️ Upload your starting image Use a clear, well-lit frame.
2. 🔁 (Optional) Add a last frame Provide an ending image if you want a smooth transition.
3. ✍️ Write your prompt Describe the motion or transformation (e.g., “camera slowly zooms out as night falls”).
4. ⚙️ Set parameters Choose duration (4s / 6s / 8s), resolution (720p / 1080p), and aspect ratio (16:9 or 9:16).
5. ▶️ Generate video Submit your request — Veo 3.1 I2V will produce motion, lighting, and audio automatically.

💡 Pro Tips

• Use consistent framing between start and end images for smoother interpolation.
• Add camera verbs like “pan,” “tilt,” “dolly,” for cinematic control.
• Keep prompts concise and clear — focus on movement and lighting.
• For realistic transitions, limit drastic composition or color shifts between frames.
• To ensure repeatability, use the same random seed value.

🧾 Notes & Limitations

• Supported durations: 4, 6, or 8 seconds.
• Frame rate: 24 FPS (fixed).
• Generation time: ~2–3 minutes for 8s @1080p.
