⚙️ Analyze Video Workflow - Automates Video Analysis with Google Gemini 🚀 Steps to Connect: Google Gemini API Key Go to Google AI and sign up to get your free API key. Create your query authorization credential using that API key in the HTTP Request nodes (e.g., "Upload File", "Get Analysis") that require a Google Gemini credential. Form Trigger Setup Ensure the On form submission node is linked and ready to accept video uploads. No additional configuration needed; the node is pre-set for video input. YouTube Video Analysis (Optional) Update the YouTube Video node’s jsonBody field with your desired YouTube URL (e.g., replace https://youtu.be/gwCQF--cARA?si=uCbaUnoRlEjHO50a with your video link). Keep the prompt as "Please summarize the video in 3 sentences" or modify it as needed. Overview of the n8n Workflow This n8n workflow automates the analysis of uploaded videos or YouTube links using Google Gemini, providing detailed descriptions or summaries of the content. It processes video uploads, extracts analysis, and stores the results, with options for real-time polling and YouTube integration. The workflow includes sticky notes with setup instructions and editable fields, formatted in Markdown for clarity, as seen in the "Example Output.txt". How it Works Uploads a video file or links a YouTube URL for analysis. Processes the video through Google Gemini to generate a detailed description or summary. Stores the analysis results and optionally polls for updates with a delay. Set up Steps Setup time: Approximately 10-15 minutes. Detailed instructions are available in the sticky notes within the workflow. Editable Fields YouTube Video Node: jsonBody** Update the file_uri field with your YouTube video URL (e.g., replace https://youtu.be/gwCQF--cARA?si=uCbaUnoRlEjHO50a with your link). Modify the text prompt if you want a different analysis (e.g., "Describe the video in detail" instead of "Please summarize the video in 3 sentences"). On form submission Node: No edits needed** Pre-configured for video uploads; ready to use as is.

Veo 3 Video Generator via VietVid.com API (n8n) Overview This workflow leverages the VietVid.com Veo3 model to generate AI videos from simple text descriptions or optional images. Users interact via a form interface, inputting a prompt (e.g., a scene description), choosing aspect ratio and model, then the system automatically submits the request to the VietVid API, monitors the generation status in real time, and retrieves the final video output. It’s ideal for content creators, marketers, and developers exploring text-to-video AI creation, supporting intelligent video generation with minimal setup. Prerequisites A VietVid.com account and API key: Register at VietVid.com to obtain your free or paid API key. An active n8n instance (cloud or self-hosted) with HTTP Request, Wait, and form submission capabilities. Basic knowledge of AI prompts for video generation to achieve optimal results. Setup Instructions 1. Obtain API Key Register at VietVid.com and generate your API key. Store it securely—do not share publicly. 2. Configure the Form In the Form Trigger node, ensure the following fields are available: text_prompt — video description (e.g., “A serene mountain landscape at sunset with birds flying”) ImageURL [optional] — optional image input for image-to-video api_Token — your VietVid API key aspect_Ratio [16:9,9:16] — dropdown to select ratio model — choose between veo3 and veo3_fast 3. Test the Workflow Click Execute Workflow in n8n. Access the generated form URL. Submit your prompt, API key, and options. The workflow will poll the VietVid API every 10 seconds until the video is ready. 4. Handle Outputs The final Set node formats and displays the video links: 720p_link — always available when ready. 1080p_link — available only for 16:9 aspect ratio. Customization Tips Enhance prompts*: Add details like style (realistic, cinematic, animated*), duration, actions, and camera/lighting for better results. Stability**: Fix the seeds value (e.g., 50000) for more consistent characters. Webhook Response: Add a **Webhook Response node to return a clean JSON payload for frontend integrations. Adjust polling delay**: Modify Wait node (8–15s) if needed to balance speed vs. API calls.

This n8n template automates daily backups of workflows and credentials to S3-compatible storage with automatic retention management. Designed for self-hosted n8n instances requiring disaster recovery protection. The workflow has three tasks: backs up all workflows via n8n API, exports and stores credentials securely, and automatically deletes outdated backups based on configurable retention policies. Perfect for administrators needing automated backup solutions with storage cost management. Target Audience n8n Administrators**: Managing production n8n instances requiring reliable backup solutions DevOps Teams**: Implementing disaster recovery strategies for automation infrastructure IT Managers**: Ensuring business continuity and compliance for critical automation workflows System Administrators**: Maintaining secure, automated backup processes for workflow management platforms How it works The workflow operates through three synchronized branches that execute automatically on a daily schedule: Workflow Backup Process: The schedule trigger initiates daily backups, retrieving all workflows via the n8n API and storing them as timestamped JSON files in your S3 bucket. Retention Management: Simultaneously, the system lists existing backup files, extracts dates from filenames, applies retention policies to identify outdated backups, and automatically deletes files beyond the configured retention period. Credential Backup: In parallel, the workflow exports all n8n credentials to a temporary file, uploads the encrypted credential data to S3 storage, and securely removes temporary files from the local system. Prerequisites Before implementing this template, ensure you have the following requirements in place: Self-Hosted n8n Instance: This template requires a self-hosted n8n installation with file system access for credential export functionality. Cloud-hosted n8n instances cannot export credentials due to security restrictions. S3-Compatible Storage: Set up an S3 bucket (AWS S3, MinIO, DigitalOcean Spaces, or any S3-compatible service) with read/write permissions configured for your backup storage needs. Access Credentials: Obtain S3 access credentials (Access Key ID and Secret Access Key) with appropriate bucket permissions for file operations (create, delete, list). System Permissions: Ensure your n8n instance has command-line access and file system permissions for credential export and temporary file management operations. Setup Instructions Step 1: S3 Bucket Configuration Create and configure your S3-compatible storage bucket: Create a new S3 bucket in your preferred region Configure bucket policies for read/write access Generate access credentials (Access Key ID and Secret Access Key) Note the bucket name, region, and endpoint URL for configuration Step 2: Import and Configure Template Import this workflow template into your n8n instance Navigate to the Config node (Manual Trigger) to customize settings Configure the following parameters: Bucket name and region Retention period (default: 7 days) Backup file naming conventions Folder structure preferences Step 3: Set Up S3 Credentials Configure S3 credentials in all storage-related nodes. Step 4: Set Up N8N Credentials Create an API key for n8n via the n8n settings of your n8n instance. Set this API key in the n8n node configuration. These credentials are neccesary to retrieve all workflows. Step 5: Configure Backup Schedule Customize the Daily Backup schedule trigger: Daily at 2:00 AM: 0 2 * * * Daily at midnight: 0 0 * * * Twice daily: 0 0,12 * * * Custom schedule: Modify cron expression as needed Step 6: Test and Validate Execute the Config node manually to verify settings Run the complete workflow to test all three backup branches Verify files appear in your S3 bucket with correct naming Confirm retention policies work by checking cleanup operations Test credential backup and temporary file removal Retention Settings The retention management system automatically maintains your backup storage: Configurable Retention Period: Set how many days of backups to retain (default: 31 days). The system automatically calculates cutoff dates and removes older files. Date-Based Cleanup: The Extract Date node processes backup filenames to determine file age, while the Keep Outdated Backups filter identifies files beyond the retention period. Automatic Deletion: Outdated files are automatically removed from S3 storage, preventing unlimited storage growth and managing costs effectively.
