Publish YouTube Videos with OpenAI & HTTP MP4 Upload (n8n)

Publish YouTube Videos with OpenAI-Generated Titles & MP4 Upload (n8n)

Turn a simple video topic and a direct MP4 link into a fully prepared YouTube upload—complete with an AI-generated, YouTube-ready title and description using OpenAI, all orchestrated in n8n.

What this workflow does

• Manual trigger: Start the workflow whenever you’re ready to publish.
• Collect inputs: Provide a public MP4 URL and a short video topic description.
• Generate YouTube metadata with OpenAI: Send the topic to OpenAI to produce a JSON response containing a YouTube-optimized title, a description, and three hashtags.
• Download and prepare the video: The workflow downloads the MP4 file from your provided URL.
• Upload to YouTube: Upload the downloaded MP4 to YouTube using the generated metadata, with Private visibility for testing.

Use cases

• Content repurposing: Convert a topic + MP4 source into consistent YouTube metadata without manual writing.
• SaaS marketing teams: Quickly publish product explainers or updates while keeping uploads private during review.
• Automation engineers: Use an example n8n workflow pattern combining OpenAI, HTTP, and YouTube upload.
• Solo creators: Standardize titles, descriptions, and hashtags for faster publishing workflows.
