I cannot tell you my experience with my own intro videos, because I have none - I can give you some feedback on how I perceive intro videos on Patreon sites as well as video streaming portals.
Advertising videos I immediately close. Always. Your current one is a good example for why: Too fast, too huge fonts, I wouldn’t even know what it’s about if I hadn’t googled you before In fact, I noticed over the years that I visit sites/channels that have advertising intros instead of personal ones considerably less than the other way around. I think there are two reasons for this: a) It feels as if the human being running the site doesn’t have to tell me anything and uses loud, huge, hectic PR to “force” me to whatever. I react allergic to that. b) In my experience people who use the personal approach often are actually interested in a personal approach. I am.
On Patreon, specifically, I think that patrons support the creator, not the product (for that one can use Amazon aka Kickstarter and others). Welcoming (potentially paying) patrons with a product ad feels … odd (again, this is about this specific place, it may be different elsewhere).
There is an argument that works the other way around, though. Most Patreon sites I were interested in (read: Where I considered supporting the creator) seemed actually abandoned. In every single case it was the personal video that made me want to support the creator. HOWEVER since the channels didn’t live up to the (personal) “promises” (like: “I am going to release a video every other week” - the last post being 3 months old with no “hold on, I’ll be back” information), it was exactly the personal approach that made me NOT support those creators:
With a “screaming, in your face ad” I would not have felt so … let’s say “sad” for lack of better words.
Read: If you plan to not deliver, an ad for me definitely wouldn’t make you look as bad as a personal video that tries (and maybe succeeds in) making some kind of bond. If you plan to be personal, be personal. If you plan to be a product, well … have fun being a product, I’m out
I wanted to talk a little about how you reach your community and fan base.
… I don’t. I create 3d tutorials. Luckily I got a number of jobs thanks to what I released over the years without doing anything in terms of “reaching a community or fan base”. I know this is not a commercially sound position, but I actually value the contacts I have had the honor of getting thanks to my videos on a personal, inter-human level.
In my world that is something very important. That, I know, is another commercially not sound position.
