Script Moat Economics

Script Moat Economics holds that in AI video production, the durable margin sits in the script, brand system, and performance data, not in the rendering layer. Rendering is converging: avatar platforms like Synthesia and HeyGen both advertise 160+ language coverage, and aggregators such as Vivideo route 15+ models through one workspace, so per-minute generation cost keeps falling toward commodity. Agencies that sell only rendered minutes compete on a shrinking price floor. Agencies that own the script library, the client's brand kit, and the hook-level performance history can re-render the same asset across formats and channels without renegotiating scope, which protects retainer value. A concrete signal: voice cloning APIs are now benchmarked on price per 1M characters, meaning the voice layer is priced like a utility. Treat generation as a cost line and scripting plus measurement as the billable asset.
