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.
