Dear @PierreAllain
If you need a Video Thumbnail to work within your Carousel:
In your Carousel select the same video that you are using for Video Thumbnail:
[image: 1612237460607-screen-shot-2021-02-02-at-4.44.03-pm-resized.png]
Then Clicking on the element and selecting "Edit Link" - Link to the Project you wish.
I hope this helps you and the function that you needed is there :)
Best
Richard
