Trend-Based AI Video Marketing Generation - n8n Workflow

E-commerce brands needing fresh, high-volume video content based on current trends.
Marketing teams aiming to leverage generative AI (GPT-4, Veo 3) for content ideation.
Users looking for advanced n8n templates that combine web research (Tavily) with large language models.
Technical users wanting to learn complex automation involving API polling loops in n8n.

This sophisticated AI marketing agent provides a complete end-to-end automation solution for video content strategy. By leveraging the power of GPT-4 combined with the real-time research capabilities of Tavily, this n8n workflow ensures your marketing concepts are always relevant and trending. The core problem it solves is the daily challenge of generating novel, effective marketing hooks.

The process starts automatically, researching trending news, generating a cohesive marketing idea for a fictional brand ("Sally’s Closet"), and then using a second GPT-4 n8n node to format that idea into a highly optimized, cinematic Veo 3 prompt. The final step involves initiating the Veo 3 generation via the FAL API, monitoring its status using a polling loop within the n8n workflow, and finally emailing the resulting video URL. This n8n template dramatically reduces the time spent on creative brainstorming and prompt engineering.

The entire process is initiated by the Schedule n8n trigger, set to run daily.

1. Scheduled Start: The Schedule n8n trigger starts the n8n workflow at a specified time (e.g., 10 AM daily).


2. Trend Research and Ideation: The first Langchain/OpenAI n8n node ("Idea Gen Agent") utilizes GPT-4 and the Tavily n8n node (web search tool) to research current trends and generate a structured video idea, connecting the trend to the target brand's products.


3. Prompt Engineering: The output is passed to the second Langchain/OpenAI n8n node ("Video Prompt Agent"). This GPT-4 agent acts as a specialized prompt engineer, transforming the creative idea into a precise, descriptive, sub-100-word prompt optimized for the Veo 3 AI video generator.


4. Video Generation Request: An HTTP Request n8n node sends this prompt to the FAL API endpoint for Veo 3, initiating the actual video creation and returning a request_id.


5. Polling Loop: The n8n workflow then enters a critical polling mechanism. It uses a Wait n8n node (90 seconds pause) followed by an HTTP Request n8n node to check the job status.


6. Conditional Check: An If n8n node evaluates if the video status is "COMPLETED". If not, the flow returns to the Wait n8n node, demonstrating advanced flow control features available in n8n.


7. Final Delivery: Once complete, a final HTTP Request n8n node retrieves the completed video URL. The last n8n node, Gmail, sends this generated video URL directly to the marketing team for immediate review or deployment.

1. Import: Copy the provided n8n workflow JSON and import it into your n8n instance using the "New > Import from JSON" option.


2. Credentials Setup:

1. Activation: Review the Schedule n8n trigger to ensure the daily time (currently 10 AM) is suitable for your operations. Activate the n8n workflow to begin automation. This powerful n8n template is ready to use once credentials are set.

Schedule Trigger: This is the initial n8n trigger, setting the automation to run daily at 10 AM. Essential for setting up a consistent daily content pipeline.
Idea Gen Agent (OpenAI/Langchain n8n node): Uses GPT-4 for creative brainstorming. Key configuration includes defining a detailed system role as a creative marketing strategist for “Sally's Closet” and enabling the Tavily tool for external research.
Tavily (n8n node): Provides the GPT-4 agent with up-to-date, real-time data on trending topics, ensuring the video ideas generated by the n8n workflow are relevant.
Video Prompt Agent (OpenAI/Langchain n8n node): A specialized GPT-4 instance focused solely on optimizing the marketing idea into a short, cinematic prompt (<100 words), ready for Veo 3. This n8n node ensures quality output for video generation.
FAL Veo 3 Post Request (HTTP Request n8n node): Sends the optimized prompt to the Veo 3 API (via FAL), initiating the generation process. It uses expressions to dynamically pass the prompt body.
Wait (n8n node): Pauses the n8n workflow for 90 seconds. This is crucial for rate limiting and providing initial time for the external API job to process.
If (n8n node): Manages the polling loop logic. It checks if the status equals "COMPLETED". If not, the flow returns to the Wait n8n node, demonstrating advanced flow control features available in n8n.
Gmail (n8n node): The final action. This n8n node delivers the generated video URL directly to the recipient, completing the daily automation cycle initiated by the n8n trigger.
