What problem does it solve?
Recording polished terminal demo videos with synchronized narration and background music is tedious: VHS captures silent video only, audio capture tools drop samples, and shell quirks corrupt typed commands. This Skill provides a tested pipeline that records the polli CLI, generates voiceover and music via the Pollinations API, and muxes everything into a finished MP4.
Core Features & Use Cases
- VHS tape conventions: Canonical bash
Hide block, announce() helper for scene titles with backgrounded TTS, and a gotcha table covering zsh races, job-control leaks, color stripping, and Unicode issues.
- Two audio pipelines: BlackHole live capture via sox + CoreAudio (recommended) or post-hoc ffmpeg overlay with
adelay timing, ducking levels, and fade-out.
- AI-generated content: ElevenLabs voiceover with emotion cues, elevenmusic instrumental tracks matched to video duration, and guidance for generating LinkedIn announcement posts and streaming ASCII outros.
- Use Case: Record a launch demo of the polli CLI for LinkedIn — five scenes with narrated titles, streaming text generation, and an ASCII wordmark outro — producing a ready-to-post
demo.mp4.
Quick Start
Copy the example folder to a temp directory, set your system output to BlackHole 2ch, and run render.sh to produce demo.mp4.
