Instead of only having paid videos, you can add a couple of free videos for people to access some of your content and get to know you. If you have a fitness site and you are selling some programs, maybe you can have an overview of the programs on a video for free to encourage viewers to purchase your content. Or if you simply want to share your content for free, this is how you can do it.
Navigate to the video you want to set as free under Content > Videos and click the video name. Under the Pricing tab, select Free for Everyone and Save.
