AI Video Prompt Builder Pro | Veo 3, Runway, Kling, Sora 2 + 18 More | JSON Output Generator

Every AI video tool wants its own prompt format. You don't have time for that. This builder ends the copy-paste-reformat cycle for good: fill in your shot once, get it back correctly for whichever of 22 platforms you're actually using — Veo 3, Runway Gen-4.5, Kling, Sora 2, Seedance, Luma, Pika, Hailuo, and 14 more.

87 fields. 16 sections. Real structured JSON that matches each platform's actual API — not a generic template that happens to say "Kling" on it.

Stop Guessing What Each Platform Wants

Veo 3 generates native synced audio. Seedance doesn't take negative prompts. Stable Video Diffusion needs an input image, not just text. Most prompt tools don't know the difference — this one does, and it builds that knowledge into every output.

87 Fields Covering What Actually Makes a Shot Work

• Action & Motion — primary action, motion speed, motion path, physical interaction, micro-expression changes
• Camera & Movement — 16 real camera moves from static locked to steadicam glide to crane reveal, not just "camera angle"
• Audio & Dialogue — dialogue, music, sound effects, voice style, and native audio sync where the platform actually supports it
• Multi-Shot Sequence — shot count, transition style, continuity, pacing — build a sequence, not just one clip
• Advanced Technical — guidance scale, steps, seed control, duration, frame interpolation for platforms with real API access
• Plus Subject, Scene, Lighting, Style, Technical, Reference, Brand Context, Narrative, and Output sections

One Field the Dropdowns Don't Cover? Type It.

Every dropdown also accepts your own custom text — a real product name, a specific brand detail, anything the preset options don't anticipate. No other prompt builder in this category gives you both structure and a genuine escape hatch.

What's Included

• PRESETS tab — 5 ready-made setups (Product Demo, Social Reel Hook, Cinematic B-Roll, Fantasy Action Sequence, UGC Style Testimonial), one click to load
• LIBRARY tab — which of the 22 platforms have real public APIs, where to paste your output, and platform-specific gotchas before you waste a generation credit
• LOG tab — track every prompt, platform, and result with one menu click
• Fully editable — every field is a guided dropdown or your own typed value
