YouTube Shorts Automation with AI-Powered Video Generation
YouTube Shorts Automation with AI-Powered Video Generation Overview This workflow automates the creation of engaging YouTube Shorts by leveraging AI tools to generate scripts, audio, images, and videos, then compiles them into a final video ready for upload. It uses OpenAI for script and image prompt generation, ElevenLabs for text-to-speech, Replicate for image and video generation, Cloudinary for audio storage, and Creatomate for final video rendering. The workflow segments the script into 6-second clips, creates corresponding visuals, and combines them with audio, adding smooth transitions for a polished result. Why is this workflow useful? Creating YouTube Shorts manually is time-consuming, requiring scriptwriting, voiceovers, and video editing. This workflow automates the entire process, enabling creators to produce high-quality, engaging Shorts in minutes. It’s ideal for content creators, marketers, or businesses looking to maintain a consistent social media presence with minimal effort. Who is this workflow for? Content Creators**: YouTubers or TikTok creators aiming to produce viral Shorts quickly. Digital Marketers**: Businesses promoting products or services through short-form video content. Hobbyists**: Individuals experimenting with AI-driven video production without advanced editing skills. What will you need to use this workflow? n8n Account**: Free or paid, hosted on n8n Cloud or self-hosted. OpenAI API Key**: For generating scripts and image prompts (GPT-4o-mini model). ElevenLabs API Key**: For text-to-speech conversion. Replicate API Key**: For generating images and videos. Cloudinary Account**: For storing audio files. Creatomate API Key**: For rendering the final video. Basic JSON Knowledge**: To understand and tweak the workflow output if needed. How does this workflow work? Trigger: The workflow starts manually via the "Test Workflow" button. Script Generation: OpenAI (GPT-4o-mini) generates a script with an intro (40-70 chars), base (280-350 chars), and CTA (55 chars), plus a title and description with hashtags. Text-to-Speech: ElevenLabs converts the script into an MP3 audio file with timestamps. Audio Upload: The audio is uploaded to Cloudinary for storage. Script Segmentation: A Python script segments the audio into 6-second clips, creating transcription chunks. Image Prompt Generation: OpenAI generates a visual prompt for each segment in the style of CNSTLL, ensuring simple, animatable visuals. Image Generation: Replicate creates a 9:16 image for each segment based on the prompt. Video Generation: Replicate’s Minimax model generates 5-second video clips from the images. Video Compilation: Creatomate combines the video clips with the audio, adding fade transitions and a final black shape for a smooth close. Final Output: The rendered video is retrieved from Creatomate, ready for YouTube Shorts. Setup instructions Import the Workflow: Copy the provided JSON into n8n and import it as a new workflow. Add Credentials: Configure OpenAI API credentials for the "Ideator" and "Image Prompter" nodes. Set up ElevenLabs API key in the "Script Generator" node. Add Replicate API key for the "Request Image," "Request Video," and "Get Video" nodes. Configure Cloudinary credentials for the "Upload to Cloudinary" node. Set Creatomate API key for the "Editor" and "Get Final Video" nodes. Test the Workflow: Click "Test Workflow" to run it manually. Replace <user-query> in the "Ideator" node with your video topic (e.g., "Fitness tips for beginners"). Verify Outputs: Check each node’s output, ensuring audio, images, and videos are generated correctly. Customize (Optional): Adjust segment duration in the "HTTP Request" node’s Python code (default: 6 seconds). Modify fade duration or video resolution in the "Create Editor JSON" node. Save and Activate: Save the workflow and activate it for regular use. Tips for getting the most out of this workflow Optimize Prompts**: Use specific, concise queries in the "Ideator" node for better script quality (e.g., "Minimalist home decor ideas"). Check API Limits**: Ensure your API accounts (OpenAI, ElevenLabs, Replicate, Creatomate) have sufficient credits. Experiment with Styles**: Tweak the CNSTLL style in the "Image Prompter" node for unique visuals, but keep prompts simple to avoid AI generation errors. Monitor Rendering Time**: Video rendering in Creatomate may take up to 70 seconds; adjust the "Rendering" node’s wait time if needed. Add Hashtags**: Enhance the generated description with trending hashtags like #YouTubeShorts, #AI, or niche-specific tags. Troubleshooting Error in Script Generation**: Verify your OpenAI API key and ensure the query is clear. Audio Issues**: Check ElevenLabs API key and confirm the script length fits within API limits. Image/Video Failures**: Ensure Replicate API key is valid and prompts are simple (avoid complex scenes or humans). Rendering Errors**: Confirm Creatomate API key and check JSON structure in the "Create Editor JSON" node. Contact Support**: Reach out to n8n Community Forum or respective API providers for persistent issues. Built with n8n Nodes**: Manual Trigger, OpenAI, HTTP Request, Set, Split Out, Aggregate, Merge, Wait. External Services**: OpenAI (GPT-4o-mini), ElevenLabs (Multilingual v2), Replicate (Flux-Cinestill, Minimax Video-01), Cloudinary, Creatomate. Custom Code**: Python for audio segmentation and JSON rendering. Example output For a query like "Morning routine hacks": Script**: Intro: "Struggling to start your day right?" Base: "Try these 3 morning hacks: 5-min meditation to clear your mind, a quick stretch routine to boost energy, and a cold shower to stay alert. Set your day up for success!" CTA: "Save this and try it tomorrow!" Title**: "3 Morning Hacks You NEED to Try!" Description**: "Kickstart your day with these easy hacks! 🧘♀️🚿 #MorningRoutine #Productivity #YouTubeShorts" Video**: A 15-second Short with three 5-second clips (meditation scene, stretching POV, cold shower close-up), synced with audio and fade transitions.
