1.1 Workflow description

Title: Create YouTube SEO metadata and thumbnails from Google Drive videos with Gemini, LemonFox and upload-post
Workflow name: Create YouTube SEO metadata and thumbnails from Google Drive videos with Gemini, LemonFox and upload-post

Automated YouTube SEO, Thumbnail Generation & Video Upload via AI, Google Drive & LemonFox

Pre-requesties:

Video uploaded to gdrive.
And sponsor file with the similar formart "videotitle_sponsors.txt"

Node-by-Node Functional Breakdown

This workflow is an end-to-end "Content-to-Publish" engine. I’ve broken it down by the specific stage of production:

Stage 1: The Intake & Access

Node Name	What it does
When File Added in Drive	The Trigger: Watches your "transcript" folder. The moment you drop a video file here, the engine starts.
If Video Mime Type	The Gatekeeper: Ensures the file is actually a video (e.g., .mp4) and not a random document or image before proceeding.
Grant Temp File Access	The Key: Temporarily changes the Drive file's permissions to "Anyone with link" so external AI tools (LemonFox) can download and process it.

Stage 2: Transcription & Data Prep

Node Name	What it does
Post Audio to Lemonfox	The Ears: Sends the video to LemonFox AI to extract the spoken word into a structured SRT (subtitle) format.
Clean SRT Content	The Editor: A JavaScript node that cleans up technical formatting issues and unescapes characters to make the text readable for the AI.
Create Text File in Drive	The Archive: Saves your clean transcript back to Google Drive for your records.
Search/Fetch Sponsor Info	The Researcher: Looks for a specific `.txt` file named after your video that contains sponsor details (Name/Email) so they can be credited.

Stage 3: AI Strategy & Creative

Node Name	What it does
Content Analysis Agent	The Strategist: Uses Gemini to analyze the transcript and find the "Big Idea." It then writes a high-CTR Title, SEO Description, and Tags.
Parse Structured Output	The Translator: Ensures the AI's creative writing is formatted as strict JSON so the next "Upload" step can understand it.
Generate Thumbnail Image	The Artist: Takes a specific "Thumbnail Prompt" written by the AI and uses Gemini (Nano Banana) to generate a high-quality 16:9 image.

Stage 4: Publishing & Cleanup

Node Name	What it does
Upload to YouTube API	The Publisher: Hits your upload endpoint, sending the original video link, the AI-generated metadata, and the AI-generated thumbnail.
Delete Original File Permissions	The Security Guard: Immediately revokes the "Anyone with link" access to your Google Drive file, locking it back down for privacy.

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.
