n8n UGC Instagram Reel Generator: OpenAI + AtlasCloud + Blotato

Turn a Product Photo into a Cinematic Instagram Reel (Auto-Rendered with OpenAI + AtlasCloud + Blotato)

This n8n workflow converts a single product image into an Instagram Reel—using OpenAI Vision to analyze the image, OpenAI to generate a video scene prompt and caption, AtlasCloud Seedance to render the video, and Blotato to publish the finished Reel to your Instagram account.

What this workflow does

• Manually executed in n8n: Runs when you trigger it manually.
• Reads configuration inputs: Loads settings such as the product image URL, OpenAI model IDs, and video duration/aspect ratio, along with polling limits.
• Analyzes the product image with OpenAI Vision: Generates a detailed visual description of the product photo.
• Creates a cinematic text-to-video prompt + caption: Uses OpenAI to convert the image description into a single scene prompt and generates an Instagram caption in the specified language.
• Renders with AtlasCloud Seedance: Submits the scene prompt to AtlasCloud and polls the prediction endpoint until rendering succeeds (or the max polling attempts is reached).
• Publishes to Instagram via Blotato: Combines the final AtlasCloud video URL with the generated caption and posts it as an Instagram Reel through Blotato.

Use cases

• E-commerce teams generating UGC-style Reel ads from product photos without manual editing.
• SaaS operators automating creative production workflows for campaigns and product drops.
• Automation engineers testing an end-to-end pipeline: Vision → prompt → rendering → social publishing.

Technical details

• OpenAI: Vision image analysis and text generation (scene prompt + caption).
• AtlasCloud Seedance: Text-to-video rendering with HTTP polling.
• Blotato: Instagram Business connection and Reel publishing.
• n8n nodes: if, set, no op, wait, merge, sticky note.

To set it up: add an OpenAI API credential (e.g., a vision-capable model such as gpt-4o), configure AtlasCloud API key with HTTP Header Auth, and authenticate Instagram in Blotato to select the target Instagram account.
