Auto-Post Veo3 Videos on YouTube

An automated workflow for creating Veo3 videos and posting them to YouTube.

YT Tutorial: https://youtu.be/DXM1VA-vDX4

Workflow Overview

The workflow is divided into three main phases:

Create Veo3 Video
Wait for Video Processing
Post on YouTube

1. Create Veo3 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)
- Video Category: A YouTube category for the video.
Get Specific Prompt: Based on the selected "Video Style," the workflow fetches specific prompt data from a Google Sheet.
Videography (AI Refinement): An AI agent (using OpenRouter's Google Gemini 2.5 Flash model) refines the user's prompt into a detailed "script-to-screen" format suitable for video generation.
Make FAL.AI Request: The refined prompt is sent to the Fal.ai Veo 3 model via an HTTP request to generate the video. The video duration is fixed at 8 seconds.
Store Data: Details of the video request, including the date requested, the refined prompt, and the request URL, are stored in a Google Sheet.

2. 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.

3. Post on 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-4.1 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.
- YouTube Category: The appropriate YouTube category code based on the user's input.
- 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, tags, and category.

Setup

To run this workflow, you need to set up credentials in n8n for:

OpenRouter: Generate API key from your OpenRouter account.
Google Sheets: Uses OAuth 2.0. Connect by authenticating your Google account.
YouTube Data API: Configure credentials to allow posting videos to YouTube.

If you do not have an n8n account, follow the tutorial at https://youtu.be/E2yQelHPUdU?feature=shared to get started.

Send daily LinkedIn post drafts with Tavily, Groq Llama 3.3 and Gmail

## Quick overview This workflow runs daily at 8 AM to rotate through a topic list, research it with Tavily web search, generate a LinkedIn post and image prompt with Groq (Llama 3.3 70B), create a Pollinations.ai image URL, and email you the post with the image attached via Gmail. ## How it works 1. Runs every day at 8:00 AM on a schedule. 2. Selects today’s topic from a rotating list based on the day of the year. 3. Searches the web with Tavily to fetch up-to-date results for the selected topic. 4. Uses a Groq-hosted Llama model to write a LinkedIn post and a matching image prompt grounded in the Tavily results. 5. Builds a Pollinations.ai image generation URL from the image prompt and downloads the generated image file. 6. Emails the post text with the image attached via Gmail, and sends a text-only fallback email if image generation or download fails. ## Setup 1. Add a Groq API credential to the Groq Chat Model node. 2. Create a Tavily API key and configure HTTP Header Auth with `Authorization: Bearer <YOUR_TAVILY_KEY>` for the Tavily Search request. 3. Connect a Gmail OAuth2 credential and update the recipient email address in both Gmail send steps. 4. Edit the topic list in the topic-selection code step if you want different rotating themes. ## Requirements - Groq API key (free tier available) - Tavily API key (free tier — 1,000 searches/month) - Gmail account (OAuth2) ## Customization - Edit the topic list inside the "Pick Today's Topic" code node to change what subjects the post rotates through. - Change the Groq model in the "Groq Chat Model" node if you want a different LLM (e.g. a smaller/faster or larger Groq model). - Adjust the schedule trigger if you want a different posting time, or swap the Gmail "send to" address to deliver the draft to someone else for review. ## Additional info This workflow emails you a draft for manual review before posting — it does not post to LinkedIn automatically. If image generation fails, a text-only fallback email is sent instead so you never miss the post text.

Generate VEO3 videos from form ideas with ChatGPT, fal.ai, Drive and Gmail

## Quick overview This workflow collects a video idea via an n8n Form, uses OpenAI to turn it into an optimized prompt, generates an 8-second VEO3 video with native audio via fal.ai, saves the MP4 to Google Drive, and emails the Drive link via Gmail. ## How it works 1. Receives a submission from an n8n Form with the requester’s email, a plain-English video idea, and a selected style. 2. Uses OpenAI (via an AI Agent) to convert the idea and style into a structured VEO3 title and detailed prompt returned as JSON. 3. Cleans and parses the AI JSON, creates a filename-safe title, and sets the generation parameters to 16:9 and 8 seconds. 4. Submits the prompt to fal.ai’s queue endpoint for the fal-ai/veo3 model and gets a request ID. 5. Polls fal.ai every 30 seconds until the job status returns COMPLETED. 6. Retrieves the final MP4 URL from fal.ai, downloads the video, uploads it to Google Drive, and emails the Google Drive web link to the requester via Gmail. ## Setup 1. Create a fal.ai account, generate an API key, and replace `YOUR_FAL_AI_API_KEY` in the fal.ai HTTP request headers. 2. Add an OpenAI API credential in the OpenAI Chat Model node and select the model you want to use. 3. Connect Google Drive OAuth2 and replace `YOUR_GDRIVE_FOLDER_ID` with the target folder ID where videos should be saved. 4. Connect Gmail OAuth2 for sending emails, then activate the workflow and use the Form URL (path `veo3-video-generator`) to submit requests.

Generate presentation decks from prompts with Encelade

## Quick overview This workflow starts a presentation generation job in Encelade from a prompt and outline hints, polls Encelade for completion, and outputs the finished deck link (or stops with an error if generation fails). ## How it works 1. Starts when you manually execute the workflow in n8n. 2. Sends the topic, slide count, audience, tone, theme settings, and outline hints to Encelade to generate a 6-slide presentation. 3. Waits 20 seconds and then checks the Encelade session status using the returned session ID. 4. If the session phase is not finished, it keeps waiting and rechecking until the phase changes. 5. When the phase is "done", it returns the generated deck link and project PID. 6. When the phase is "failed", it stops the workflow and raises an error with the failure details. ## Setup 1. Install and configure Encelade credentials in n8n for the Encelade node. 2. Update the generation inputs (topic, page count, outline hints, audience/tone, theme mode, and media provider) to match the deck you want to create. 3. Ensure the workflow has enough time to complete by adjusting the 20-second wait interval if your Encelade generations typically take longer.
