Like Instagram Stories Highlights, Vidjet allows you to group several videos into a thumbnail.
It comes handy to better organise video types on your pages, and improve the look-and-feel of your video components.
This feature works with Stories & Carousel formats.
Finally, here's our recommendation to organise your thumbnails:
Informative videos about the product
UGC videos and reviews
Generic videos about your brand, shipping, etc
We hope this helps!
