The best way to feature videos and collections on your Home Page is to enable the Featured Category block in the theme editor and select a category.
NOTE: Most themes include a block on the Home Page called Featured Category. If your theme does not have a featured category block, it may be under a different name: Ara = Most Watched, Phoenix = Browse Programs, and Pyxis = First Tab
Navigate to the Customization tab and click Customize. You'll see the Featured Category option and can set the category here.
