Create reusable character action clips

Part of the AI character reel system. Use it for stock clips you reuse across reels, such as an intro or a call to action. An Airtable button on a prompt library record calls the webhook with the base, table, record and theme assets table ids.

The workflow creates a theme asset record, turns the prompt text into speech with the selected character's ElevenLabs voice, and uploads the audio to Cloudinary. It then sends the character image and audio to the Kling AI avatar model on fal.ai, checks every 10 seconds until the clip is ready, and saves the video, the audio and the duration to the asset record with the status To Do.
