Teyuto, a Uscreen/Vimeo alternative from Italy

I suggest Teyuto, which was on sale on Appsumo a few years ago.

They have video CMS, live streaming, and RTMP features. They offer a free trial and a pay-as-you-go model, which is both cost-effective and ideal for beginners. (https://appsumo.com/products/teyuto/#reviews)
