# VideoLens

> VideoLens (https://videolens.cc) is a professional AI-powered video analysis tool. Upload any video — or paste a link from YouTube, Douyin, and more — and VideoLens reverse-engineers the professional AI prompts behind it, produces a director-grade scene-by-scene breakdown, transcribes the dialogue, and generates ready-to-use, shot-by-shot prompts in Seedance 2.0's official storyboard format. Built for content creators, filmmakers, marketers, and AI-video enthusiasts who want to understand and recreate any video with tools like Sora, Runway, Kling, Veo, and Seedance.

VideoLens analyzes the entire video to understand its content, then returns three deliverables: (1) a **director-grade deep breakdown** — detected scenes, a representative key frame per scene, professional film-analysis prompts (shots, composition, lighting, color), and scene-aligned dialogue transcription; and (2) a **Studio (创作助手) deliverable** — structured, ready-to-use storyboard prompts written in Seedance 2.0's official format, with per-shot visual prompts, named characters/scenes/props for consistency, first-frame (text-to-image) prompts, and inline audio (dialogue/SFX) plus background music; and (3) a **Production Prompt (创作剧本) deliverable** — the breakdown recomposed into a production-grade, ready-to-generate script where every shot is decoupled into clean fields: a visual prompt (shot size up front + entity tags), TTS-clean dialogue (no names or stage directions baked into the spoken text), ambient sound with BGM, and precise per-shot duration. A single-image analysis mode reverse-engineers the prompt behind any still image. It is available in 11 languages and is accessible via the web app, a public API, and an MCP server.

## Core Features

- **Smart Scene Detection**: Auto-detects video shot transitions with millisecond-level precision
- **Key Frame Extraction**: Captures a representative frame from each scene and builds high-quality grids for analysis
- **AI Analysis Report**: Generates professional film-analysis prompts and reports covering shots, composition, lighting, and color — ready for AI video generation tools (Sora, Runway, Kling, Veo, Seedance)
- **Prompt Reverse-Engineering (视频转提示词 / 视频提示词反推 / video-to-prompt / video prompt reverse-engineering)**: Reverse-engineers the AI generation prompts behind any video or image — the exact prompts you would need to recreate it in Sora, Runway, Kling, Veo, or Seedance
- **Studio — Seedance 2.0 Storyboard Prompts (创作助手)**: Produces structured, ready-to-use, shot-by-shot prompts following Seedance 2.0's official best-practice spec. The video is split into ≤15-second tasks, each with per-shot visual prompts, named characters/scenes/props for cross-shot consistency, first-frame (text-to-image) prompts, and inline audio (dialogue/sound effects) plus background music in Seedance's official symbol notation — ready to paste straight into Jimeng / Seedance
- **Production Prompt — Ready-to-Generate Script (创作剧本)**: Recomposes the breakdown into a production-grade, directly-usable script in Seedance 2.0 storyboard format. Every shot is decoupled into clean, separable fields — visual prompt (shot size up front + entity tags), TTS-clean dialogue (no names/emotions baked in), ambient sound effects with background music, and precise per-shot duration, with acting emotion folded into the visual description — so each field pastes straight into the right slot of an AI video / TTS engine without contamination
- **Speech Transcription**: Auto-extracts audio and transcribes dialogue with high accuracy, precisely aligned to each scene and shot
- **Full Script Generation**: Produces a complete shot-by-shot script with stage directions, dialogue, and technical notes
- **Image Analysis**: Single-image mode that reverse-engineers the prompt behind any still image
- **Multi-language**: 11 languages — English, Chinese (Simplified & Traditional), Japanese, Korean, Spanish, Arabic, Portuguese, Russian, French, German

## How It Works
