Veo 3 JSON Guide

This tool turns any idea into clean JSON for Veo 3. Use these creative fields only:

• prompt — specific scene: subject, action, setting, time, camera feel.
• negative_prompt — avoid artifacts (e.g., blurry, watermark, heavy flicker).
• camera_movement, style, lighting, mood, color_palette
• subject_focus, background, effects

Tips: Keep it single-scene. For Image→Video, add motion cues only—don't re-describe the image.
