Do you mean using a video to present yourself and what you do on Patreon to make people subscribe is better than having just text and images describe it? Or did you mean it helps to sometimes add content that is video based, like...I don't know, speed painting process or something?
I'm not in the process of starting a Patreon right now, but I'm thinking that I might want to later when I start working on bigger comic projects, so I'm trying to take notes on what methods will give the best results. Any information helps!
