Generate B-roll images from prompts

Part of the AI character reel system. An Airtable button on a B-roll record calls the webhook. The workflow marks the record as in progress, finds the generated character images for the theme and joins their links into a list of reference images.

It then sends the B-roll prompt and those references to the image model set in your AI models table, using that model's request URL and JSON template, so you can swap image providers without editing the workflow. It checks the job every 10 seconds until it is done, then saves the image file and file name to the B-roll record and marks it as generated. The cost is logged to your AI usage table.
