One prompt, $5, 10 minutes: turning a 54-minute DevDay keynote into a 90-second recap with GPT-6.1 Sol

gabrielchua shares a practical workflow: using GPT-6.1 Sol inside Codex, a single appshot and one prompt turned a 54-minute DevDay keynote recording into a 90-second recap in about 10 minutes for roughly US$5.
The model cut the footage, added captions, and highlighted key moments on its own — a working demo of driving video editing through a coding agent.
