YouTube video to movie poster carousel copy

A webhook receives the ids of a YouTube video record in Airtable. The workflow reads the final video title and the cleaned transcript, and an OpenAI model writes the text for a carousel styled like a movie poster: ten familiar phrases tied to the topic, five taglines for each, and five short cinematic titles for each.

It saves the output as a new Instagram carousel post in your posts table, with the video context attached and the carousel status set to In Progress, then marks the video record's carousel assets as created. An image analysis step for brand colors sits in the file but is not connected.
