How I built a production landing page video in 3 hours using Claude, Remotion, and ElevenLabs

A developer documents making a 35-second homepage demo video: Claude plans and scripts six scenes, an agent captures app screenshots, each scene is a Remotion React component driven by one shared config, ElevenLabs makes per-scene voiceover and a music loop, then it renders to 1080p MP4. Covers fixing robotic voiceover, overlapping audio, timing drift and music levels.

Disclosure Video is for the author's own product (FitComrade); ends with a call to book his consulting.
