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

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.
