n8n Workflow: Generate Viral YouTube Shorts with Reka AI

Turn any YouTube video link into vertical, subtitle-ready viral Shorts—automatically

This n8n workflow takes a YouTube URL submitted through an n8n form, uses Reka AI Vision Agent to generate short vertical “viral” clips with subtitles, then downloads each rendered clip and uploads it to both Google Drive and YouTube.

What this workflow does

• Receives a YouTube link from an n8n form submission.
• Creates a clip-generation job by sending the URL to the Reka AI Vision Agent clips endpoint (9:16 aspect ratio, subtitles enabled, up to 2 clips with a maximum of 30 seconds).
• Waits and polls for completion: it pauses for 20 seconds, then repeatedly checks job status using the returned job ID until Reka reports completed.
• Downloads and processes outputs: splits the job output array into individual clip items and downloads each clip from the provided signed S3 URL.
• Uploads to storage + publishing: uploads each clip to a selected Google Drive folder and uploads it to YouTube with the generated title, caption, hashtags, and the configured public visibility.

Use cases

• SaaS operators who want to offer “Shorts generation” as an automated service to customers.
• Automation engineers building a pipeline that converts long-form YouTube URLs into vertical content for distribution.
• Creators/teams managing bulk repurposing workflows while keeping outputs archived in Google Drive.
