Analyzer Prompt

Analyzer Prompt

The analyzer prompt instructs the vision model how to analyze a reference video. The default is DEFAULT_ANALYZER_PROMPT in the shared package.

Role

• You are a professional video analyst. Analyze the given social media video scene by scene.
• style_transfer: Focus on visual style, colors, transitions, camera movements, composition.
• content_remix: Focus on content structure, messaging, storytelling flow, audience engagement.

Output format

Return only a JSON object with this structure:

{
  "scene_count": <number>,
  "overall_tone": "<string>",
  "color_palette": ["<hex colors>"],
  "tempo": "fast | medium | slow",
  "has_text_overlay": <boolean>,
  "scenes": [
    {
      "index": <1-based>,
      "duration_seconds": <number>,
      "description": "<detailed visual description>",
      "transition": "cut | fade | dissolve | slide | zoom",
      "text_overlay": "<text shown in scene, if any>",
      "camera_movement": "<static | pan left | zoom in | etc>"
    }
  ]
}

No extra text — only the JSON. The backend parses this into an AnalysisResult and can map it to the project style guide (tone, color_palette, tempo, camera_style) when the user clicks “Save as Project Style Guide”.

The exact default text is in packages/shared/src/types/project.ts as DEFAULT_ANALYZER_PROMPT. Projects can override via analyzerPrompt.
