Descriptions:
All About AI demonstrates a fully autonomous video production pipeline built on Claude Code (Opus 4.5), Whisper, ElevenLabs, FFmpeg, and Nano Banana Pro. The system takes a long-form source video — a 27-minute episode from the YouTube channel Chilling Scares — and produces a standalone narrated video story without any manual editing step.
The workflow runs through ten stages encoded as a single Claude Code custom slash command: audio extraction, Whisper transcription with per-segment timestamps, AI script writing, ElevenLabs voiceover synthesis, re-transcription of the voiceover to align timing, visual timeline generation, Nano Banana Pro image generation for footage gaps, clip selection and trimming, FFmpeg composition, and archiving to prevent duplicate stories. A live run of this pipeline produces a 7-minute-and-20-second narrated video in approximately 17 minutes of total runtime, incorporating 13 sourced clips and 4 AI-generated images.
The custom slash command approach — where all ten steps are defined as instructions Claude Code follows sequentially — is a central architectural detail that makes the pipeline fully hands-off after a single invocation. For developers and content creators exploring automated video repurposing, this is a thoroughly documented reference for chaining Whisper, ElevenLabs, image generation, and FFmpeg under Claude Code orchestration.
