Emergence Video Producer

Automated video production pipeline for product demos and academic tutorials. Uses WebReel for browser recording, DashScope/Edge-TTS for narration, and FFmpeg for assembly.

Skill: Emergence Video Producer 🎬

This skill transforms a Markdown "Video Script" into a polished tutorial video. It is designed for headless operation on cloud VMs, enabling agents to produce visual documentation autonomously.

1. Prerequisites

Ensure the following tools are in the path:

• webreel (for browser recording)
• ffmpeg (for assembly)
• edge-tts or dashscope credentials (for narration)
• Pillow (for frame extraction if WebP conversion is needed)

2. Interaction Model: The Interview

Unlike rigid CLIs, this skill starts with a Human-in-the-Loop Interview.

The Discovery Phase

The agent must proactively ask the following:

1. Objective: "What is the primary goal of this video? (e.g., Feature Launch, Academic Summary, Onboarding)"
2. Mode: "Should this be a Browser Walkthrough (WebReel) or a PPT-style Presentation (Slidev)?"
3. Tone: "What is the desired persona? (e.g., Professional, Hype, Scientific)"
4. Target URL/Content: "Which website are we recording, or what are the key slides?"

3. Workflow Phases

Phase 1: Ideation & Storyboarding

Based on the interview, the agent drafts a storyboard.md. This is a negotiated artifact.

• DO NOT ask the human to write the Markdown.
• DO ask the human to "Review and Approve" the draft.

Phase 2: Configuration & Asset Prep

Once approved, the agent automatically generates:

1. For Browser Mode: A webreel.config.json with precise selectors and timings.
2. For Slide Mode: A slides.md for Slidev rendering.
3. Audio: Narration text synthesized into high-quality TTS.

Phase 3: Production (The Engine)

The agent executes the headless recording and assembly. It handles:

• Browser automation (WebReel)
• Slide rendering (Slidev)
• Frame extraction and FFmpeg merging

Phase 4: Taste Gate & Distribution

The agent presents the video for final "Taste Gate" approval before publishing to ClawHub or social platforms.

4. Usage Example

bash

# Generate a video for the current project
hermes run emergence-video-producer --script video-script.md --output tutorial.mp4

5. Development Notes

• Framerate Sync: The assembly script automatically adjusts the framerate: FPS = TOTAL_FRAMES / AUDIO_DURATION.
• Browser State: Ensure the product is accessible via URL or a local dev server before recording.
