Veo 3.1 Image-to-Video Parameter Illustrated: Single-Shot Demonstration

A single 8-second short film is used to visually demonstrate the core input parameter combination of the Veo 3.1 image-to-video pipeline. The work first generates a 16:9 keyframe image through the pipeline (corresponding to image_url), then uses a text prompt to describe the motion of that image, and explicitly sets required fields such as resolution and duration, forming a submission snapshot that can be directly reproduced. For developers, the value of this entry lies in presenting the minimal viable structure of "required fields + image input + motion prompt": image_url determines the subject and composition of the frame, prompt only describes the camera and motion, negative_prompt is used to exclude unwanted elements, and seed can be used to reproduce the same result. In the schema, fields such as aspect_ratio and generate_audio all carry default values; this entry is submitted with default behavior, making it a convenient starting template for integrating into the Gemini API video generation workflow. It is suitable for API integration and joint debugging, baseline evaluation of image-to-video results, and single-shot previews for scenarios such as marketing short films and concept storyboards.
