🎬 Generate AI video clips from YouTube using Reka Vision API and Gmail

⚡ 958 views · 🎬 Content Creation & Video

💡 Pro Tip — YouTube’s API quotas can be a bottleneck when you’re pulling data at scale. ScraperNode is a community node with dedicated scrapers for channels, videos, and comments — no quota limits, just structured data.

Description

Try It Out!

This n8n template demonstrates how to use Reka API via HTTP to AI generate a clip automatically from a YouTube video and send email notifications.

How it works

• Looking at the RSS feed of a YouTube channel, the flow will be triggered when there is a new video published.

• Using Reka’s API, we will submit a request for creating a clip using AI. You can customize:

  • the prompt to generate the clip
  • decide if you want captions or not
  • decide the minimum or maximum duration of the clip

• Wait a little while, the magic happens

• Check if the job status is completed

  • If yes, it send an success email
  • If no, it will loop
  • As a failsafe, after 10 iterations in the loop, it will send an error email

🔧 Configurations

After importing the template, here is some information to customize your clips the way you like them.
