• Edit the HTTP Request node for Gemini
• Adjust the prompt text to match your style preferences
• Test different aspect ratios (current: 1:1 square format)

Customize Script Generation

• Modify the Basic LLM Chain node prompt
• Adjust video segment duration (current: 7-8 seconds each)
• Change dialogue style and tone requirements

Video Generation Settings

• Update VEO3 API parameters in HTTP Request1 node
• Modify aspect ratio (current: 16:9)
• Adjust model settings and seeds for consistency

Output Customization

• Change final video format in MediaFX node
• Modify Telegram message templates

Workflow Operation

Phase 1: Image Reception and Enhancement

1. User sends product image via Telegram
2. System prompts for enhancement instructions
3. Gemini AI analyzes and optimizes image
4. Enhanced square-format image returned

Phase 2: Analysis and Script Creation

1. System requests dialogue concept from user
2. AI analyzes image details and environment
3. Claude generates realistic 2-segment script
4. Scripts respect physical constraints of original image

Phase 3: Video Generation

1. Two separate videos generated using VEO3
2. System monitors generation status
3. Videos merged into single flowing sequence
4. Final video delivered via Telegram

Troubleshooting

Common Issues
