Automated Video Narration with AI Vision and TTS
detail.loadingPreview
Transform your videos into engaging content effortlessly. This n8n workflow automatically downloads a video, extracts key frames using OpenCV, leverages OpenAI's GPT-4o vision capabilities to generate a detailed narration script, and then converts that script into a voiceover using AI text-to-speech, finally uploading the complete audio to Google Drive.
About This Workflow
This comprehensive n8n workflow streamlines the complex process of video content creation. By integrating powerful AI tools, it automates video analysis and narration generation. Starting with a video download, the workflow intelligently extracts representative frames, which are then processed by OpenAI's GPT-4o multimodal model to understand the visual content and craft a cohesive script. This script is subsequently transformed into a natural-sounding voiceover using GPT-4o's advanced text-to-speech capabilities, ready for upload to your Google Drive. Perfect for marketers, educators, or content creators looking to scale their video production.
Key Features
- Automated Video Ingestion: Downloads videos from specified URLs.
- Intelligent Frame Extraction: Utilizes Python (OpenCV) to capture evenly distributed frames for AI analysis.
- Multimodal AI Vision: Leverages OpenAI GPT-4o to analyze video frames and generate contextually rich narration scripts.
- Advanced Text-to-Speech: Converts generated scripts into high-quality, natural-sounding audio voiceovers using GPT-4o's TTS.
- Seamless Cloud Storage Integration: Automatically uploads the final audio narration to Google Drive.
How To Use
- Start the Workflow: Manually trigger the "When clicking 'Test workflow'" node to initiate the process.
- Configure Video Source: In the "Download Video" node, update the
URLparameter to your desired video source. Ensure the video format is supported by OpenCV. - Set OpenAI Credentials: Verify your OpenAI API credentials are correctly set up and selected in the "OpenAI Chat Model" node. GPT-4o is required for multimodal (vision and TTS) capabilities.
- Google Drive Setup: In the "Upload to GDrive" node, connect your Google Drive account and specify the target
Folder IDwhere the generated audio narration should be saved. - Run and Review: Execute the workflow to download the video, generate the script and voiceover, and upload the final audio file to your Google Drive.
