Well, there are several ways you can monetize your videos.
The first should be fairly obvious - Youtube. If your videos are of quality and you've established a niche, you'll probably be able to gain a large following on Youtube. Once you reach the requirements for monetization (I think it's 100,000 views and 4000 subscribers), you can sign up for companies to put ads before your videos. You'll get money for ever yperson who watches your ad all the way through. This is the way most Youtubers make money. The larger your audience, the more money you make.
Second, if you have video content, that probably means you know how to make videos. You can go on job boards and freelancing sites like Fiverr to sell your services to people online. There are lots of buyers that need professional video editors/makers, and if you freelance they can pay you to take care of those needs for them.
