How to show videos from subdomain wordpress install to main blog home page

My main blog is at https://www.environmentabout.com and I have a video section at a subdomain wordpress installation at https://video.environmentabout.com

I want to show recent videos from videos blog on main blog. If you see my video blog, there is a content carousal which slides the recent video posts with thumbnails and the title of the video.

I want a similar content carousal on my main blog home page which can show recent video posts from my video blog installed in subdomain.

I searched for a plugin that can do this by importing rss from the subdomain install, but no plugin has the feature I require.

How can I show the recent video posts from my subdomain to the home page of main blog?
