Create a B-roll image style prompt

Part of the AI character reel system. An Airtable button calls the webhook with the record to work on. The workflow reads the theme angle, setting and character look, finds the approved character image for that theme, and sends the image and a prompt to an OpenAI vision model.

The model returns one style prompt for look, lighting and mood that is added to every B-roll scene prompt, so the images stay consistent. The prompt is saved to the record's b-roll style prompt field and the status moves to AI Complete. A Code step works out the cost and logs it to your AI usage table. The timestamped B-roll prompt step uses this style prompt next.
