Codex Just Replaced 1,000 Hours of Video Editing Tutorials
Riley Brown puts Codex on a video-editing workflow and walks through replacing tutorial-driven editing with agent-driven edits.
Riley Brown points Codex at video editing and shows how far one prompt now gets you.
What is it?
A Riley Brown demo where he uses OpenAI's Codex agent to drive a video-editing workflow — automating the kind of tasks that used to require working through 1,000 hours of editing tutorials.
How does it work?
Brown sets up Codex with access to his editing tools, gives it high-level prompts, and shows the agent producing usable edits with minimal hand-holding.
Why does it matter?
Coding agents driving non-coding workflows is one of the more underrated patterns of late April. This is a concrete example most viewers can replicate.
Who is it for?
Creators who want to stop hand-editing and have an agent do the menial parts.
