Narrated retro terminal-game style video with archival clips

Another fun experiment with Opus 5.5, which really is amazing at video making As a child, I loved the Infocom games, and I think playing those terminal-based games really helped me now as I work with terminal agents almost all the time This video took me about 10 minutes to prompt, in part because I ran a Gemini deep research prompt for the agent, and then it was made while I did a bunch of other things Here's the tech stack I used (drawing on an internal repo of recipes we've built) - Gemini Deep Research: background research - yt-dlp: downloads the archival clips - Grok Imagine: scene images and image-to-video clips - Gemini 3.8 Flash TTS: narration - WhisperKit: checks each narration take word for word - Lyria 3.5: music - Remotion: composes and animates every frame - faster-whisper: word timing for the captions - agy, grok, astra agents: reviewing the finished work Incredible
