Google Sheets Setup

Before running the workflow, ensure your Google Sheet is structured as follows:

Column Name	Description
title	Video title (e.g., "Elijah's Fiery Chariot")
bibleverse	Corresponding Bible verse reference
idea	Brief description of the scene
style	Animation style (e.g., cinematic, vibrant, etc.)
caption	Suggested caption for social media
videoStatus	Status of video creation (To Do, Created)
publishStatus	Publishing status (Not Processed, Processed)

Step-by-Step Workflow Explanation

1. Extract an Idea from Google Sheets

• The workflow retrieves the first row where videoStatus = "To Do".
• Marks it as Processing to avoid duplicate processing.

2. Generate a Prompt for AI Image Creation and Sound Effects/Audio

• Uses Anthropic Claude or Google Gemini to generate prompts.

3. Generate an AI Image with Flux AI

• Sends the prompt to Flux AI to create a high-quality image.

4. Animate the Image Using RunwayML

• The generated image is sent to RunwayML, which animates the image.

5. Generate Sound Effects and Voiceover with ElevenLabs

• ElevenLabs produces a realistic narration based on the video content.
• Background sound effects (e.g., storm sounds, fire crackling) are also generated.

6. Merge Video and Audio Using Creatomate

• Creatomate compiles the animated video with the audio.

7. Upload and Publish to YouTube

• The finalized video is automatically uploaded to YouTube using the YouTube API.

8. Update Google Sheet Status

• Marks videoStatus as Created.
• Marks publishStatus as Processed.
