There are a few choices for sites that want to host your videos. All of them have their pros and cons. A couple years back I decided to try out Rumble.com for some videos.
Rumble has some interesting monetization options. If you let them manage the video and it does well... it could make you some decent money. So far, none of my videos have done really really well, but I have made a few bucks there.
My Meager Earnings after about a year and a half
Here's a video I put up a year and a half ago and it never did anything... perhaps after watching it you'll know why LOL

Steemit Support?
It turns out that Rumbe videos aren't really that Steemit friendly since there is no native support for the video url's like there are for YouTube, DTube and some others.
If your concern for a video sharing service was strictly based on sharing here on Steemit, then Rumble is not your man... however if you wanted another site to share videos to that might make you money, then maybe you'd like to look at Rumble as an option.
They also have a decent referral program so if you decide to sign up, please consider using my link! I would very much appreciate it ;)
