The author used a local AI model, Gemma 4, to index a year's worth of video footage on their 2021 MacBook, creating a searchable archive with descriptions and metadata. The process involved using various tools, including Claude Code, DaVinci Resolve, and ElevenLabs, to extract frames, transcribe audio, and detect faces. The author notes that local AI models can be powerful and efficient, even on older hardware. The project aimed to solve the problem of organizing and searching large video archives.
