Demo Video Generator

Overview

Generate 1920x1080 demo videos with voiceover, transitions, and CSS animations from a single prompt. Orchestrates Playwright (HTML-to-frame rendering), FFmpeg (compositing and transitions), and Edge TTS (neural voiceover) MCP servers.

Prerequisites

Python 3.11+ and
```
uv
```
package manager
FFmpeg installed (
```
ffmpeg -version
```
)
Playwright chromium browser (
```
uv run playwright install chromium
```
)
Internet connection for Edge TTS voice synthesis

Instructions

Install the framecraft plugin from the marketplace:

claude plugin marketplace add jeremylongshore/claude-code-plugins-plus-skills
claude plugin install framecraft@claude-code-plugins-plus

Quick Start

uv run python framecraft.py init my-demo        # scaffold a project
uv run python framecraft.py render scenes.json --auto-duration
uv run python framecraft.py validate output.mp4  # quality check

MCP Orchestration

When Playwright, FFmpeg, and Edge TTS MCP servers are available, framecraft orchestrates them directly for maximum control over each frame and audio segment.

Pipeline Fallback

When MCP servers are not available, framecraft runs an atomic CLI pipeline that handles everything in one call.

Workflow

Story design -- Choose a narrative arc (problem-solution, hero journey, before-after)
Scene authoring -- Write HTML scenes with CSS animations, or use built-in templates
Rendering -- Playwright captures frames, Edge TTS generates voiceover, FFmpeg composites

Output

1920x1080 MP4 video with voiceover and transitions
Individual scene previews for iteration
Validation report for quality assurance

Error Handling

Error	Cause	Fix
`ffmpeg: command not found`	FFmpeg not installed	Install via `brew install ffmpeg` or system package manager
`playwright._impl._errors.Error`	Chromium not installed	Run `uv run playwright install chromium`
`edge_tts.exceptions.NoAudioReceived`	TTS service unavailable	Check internet connection; retry after a few seconds
`FileNotFoundError: scenes.json`	Missing scene config	Run `uv run python framecraft.py init my-demo` first
Blank or black frames	HTML scene rendering failed	Check HTML syntax and ensure assets are accessible
