++What it is++ An automated workflow for creating Kling 2.5 videos and posting them to YouTube. The workflow is divided into three main phases: Create Kling 2.5 Video Wait for Video Processing Post to YouTube ++Create Kling 2.5 Video++ This phase handles the initial video creation based on user input. Type Prompt: A form trigger allows the user to input details for the video, including: Prompt: A simple scenario for the video. Video Style: (e.g., Dialogue, Monologue, Advertisement, Documentary) Aspect Ratio: (e.g., 16:9, 9:16, 1:1) Videography (AI Refinement): Refines the user’s prompt into a detailed “script-to-screen” format suitable for video generation. FAL.AI Request: The refined prompt is sent to the Fal.ai Kling 2.5 model via an HTTP request to generate the video. Store Data: Details of the video request, including the date requested, the refined prompt, and the request URL, are stored in a Google Sheet. ++Wait for Video Processing++ Wait 5 mins: The workflow pauses for 5 minutes. This waiting period is necessary as it typically takes 3–5 minutes for the video to be ready after the generation request. ++Post to YouTube++ This phase focuses on generating YouTube SEO details and uploading the video. YT Video SEO (AI Generation): An AI agent (using OpenRouter’s OpenAI GPT-5 Mini model) acts as a YouTube SEO specialist and viral content strategist. It generates the following details for the YouTube video: Video Title: A compelling title (less than 6 words). Video Description: A detailed description. Video Tags: Relevant tags to maximize discoverability. The AI agent is configured to follow guidelines for virality and YouTube’s tag limits. Structured Output: Parses the structured JSON output from the AI agent. Get Keywords: Extracts and formats the video tags into a comma-separated list suitable for YouTube. Fetch Video Credentials: Fetches the video URL and other credentials from Fal.ai . Download Video: Downloads the generated video file. Post on YouTube: The video is uploaded to YouTube using the generated title, description, and tags. ++Setup++ To run this workflow, you need to set up credentials in n8n for: OpenRouter: Generate API key from your OpenRouter account.
