JSON Prompt Generator

Build a validated video prompt as JSON in a guided 5-step wizard. Pick a starting template, choose a model (Veo, Sora, Kling, Runway Gen-4, Luma Ray 3, or Hailuo), describe the scene, tune the cinematography with clickable chips, and copy a ready-to-paste JSON object. The schema and model limits are fully configurable, and a built-in linter checks any pasted JSON for you.

How to Use This Tool

Follow the 5-step wizard and copy the generated JSON into Veo, Sora, Kling, Runway Gen-4, Luma Ray 3, Hailuo, or any prompt-to-video tool. The builder is deterministic: it assembles your inputs into JSON and does not render video.

1. Start

Pick a starting template (Cinematic, Product / ad, Action, or Dreamy) or start blank. Templates pre-fill the style choices so you can jump straight to describing your shot.

2. Select a model

Choose Veo, Sora, Kling, Runway Gen-4, Luma Ray 3, or Hailuo. The wizard adapts instantly: the duration range, allowed aspect ratios, and audio field visibility all follow the selected model. Veo and Sora generate native audio; the other models ignore the audio field but honor camera and motion.

3. Describe the scene

Fill the subject (who or what the camera is on) and the action (what it is doing, with a clear arc). Add an environment for time and place. These are the core of the prompt.

4. Style the shot

Tap chips to pick camera movement, lens, lighting, color grade, and mood, then set the duration. Every option value is validated against the schema and filtered to what the selected model supports.

5. Review and copy

The output updates live and only includes keys with values, in schema order: subject, action, environment, camera, lens, lighting, grade, mood, audio, duration, aspectRatio. Copy it to your clipboard or download it as a .json file.

Validating JSON

Paste any JSON prompt into the Validate JSON section and pick a model. The linter reports missing required keys, unknown keys, invalid enum values, out-of-range durations, and aspect ratios the selected model does not support.

Features

  • Guided 5-step wizard with a progress bar
  • Starting templates plus an example shot
  • Clickable chip selectors instead of plain dropdowns
  • Configurable schema, templates, and model limits from a single config file
  • Per-model duration clamping and aspect ratio filtering
  • Built-in JSON linter with per-model checks
  • Bundled schema reference table
  • Draft auto-save in the browser (localStorage)
  • Copy JSON, download .json, and Ctrl/Cmd+Enter to copy

सामान्यप्रश्नाः

Short उत्तरम् for the प्रश्नः उपयोक्तारः ask before trusting the फलम्

The output uses these keys in order: subject, action, environment, camera, lens, lighting, grade, mood, audio (Veo/Sora only), duration, and aspectRatio. Required keys are subject, action, duration, and aspectRatio.

No. It is a deterministic builder that arranges your inputs into JSON. Paste the output into a video model UI such as Veo, Sora, Kling, Runway, Luma, or Hailuo to generate the actual video.

Only Veo and Sora generate native audio, so the audio field is hidden for Kling, Runway Gen-4, Luma Ray 3, and Hailuo. The linter still warns if you paste JSON that includes an audio key while linting against those models.

Veo: 1–8s at 16:9 or 9:16. Sora: 1–60s at 16:9, 9:16, 1:1, or 4:5. Kling: 1–15s at six ratios. Runway Gen-4 and Luma Ray 3: 5–10s at six ratios. Hailuo: 5–10s at 16:9, 9:16, or 1:1. The schema table shows the exact limits.

No. Everything runs in your browser. Your draft is saved only in your browser's local storage and is never transmitted anywhere.

Yes. Models, templates, durations, aspect ratios, and enum options are defined in config/json-prompt-generator.php. The tool reads everything from that single config file.
