1.1 Workflow description

Title: Post AI videos to YouTube with Fal AI Veo3.1, Google Sheets, and YouTube API
Workflow name: Post AI videos to YouTube with Fal AI Veo3.1, Google Sheets, and YouTube API

What It Is

An automated workflow for creating Veo3.1 videos and posting them to YouTube.

The workflow consists of three main phases:

Create Veo3.1 Video
Wait for Video Processing
Post on YouTube

Create Veo3.1 Video

This phase handles initial video creation based on user input.

Type Prompt

A form trigger collects the user’s inputs:

Prompt: A simple scenario for the video.
Aspect Ratio: e.g., 16:9, 9:16, 1:1
Videography (AI Refinement): An LLM refines the user’s prompt into a detailed "script-to-screen" format suitable for video generation.

Make FAL.AI Request

Sends the refined prompt to the Fal.ai Veo 3.1 model via HTTP request.
Video duration is fixed at 8 seconds.

Store Data

Stores video request details in a Google Sheet, including:

Request date
Refined prompt
Fal.ai request URL

Wait for Video Processing

The workflow pauses for 5 minutes.
Veo videos typically require 3–5 minutes to finish processing.

Post on YouTube

This phase generates YouTube-optimized metadata and uploads the final video.

YT Video SEO

An LLM (acting as a YouTube SEO + viral strategist) generates:

Video Title: Under 6 words
Video Description: Detailed and optimized
Video Tags: Relevant tags for discoverability

It follows virality best practices and YouTube’s tag rules.

Structured Output

Parses structured JSON returned by the AI agent.

Get Keywords

Extracts and formats tags into a comma-separated list suitable for YouTube.

Fetch Video Credentials

Retrieves the final video URL and metadata from Fal.ai.

Download Video

Downloads the generated video file.

Post on YouTube

Uploads the video with the generated title, description, tags, and category.

Setup

To run this workflow, configure the following credentials in n8n:

OpenRouter

Generate an API key from your OpenRouter account.

Google Sheets

Uses OAuth 2.0
Authenticate with your Google account.

YouTube Data API

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.
