I started into stock video around 2020. Initially on Shutterstock, and a few other sites, but by 2021 I had decided to go exclusively with Pond5 for video clips. Pond5 gives me a more simple and streamlined interface from a contributor point of view, and allows me to set the rates.
My Videos can be seen on Pond5 (this link is to the content that was previously available on other sites). Newer content is exclusive to Pond5
