I think most people underestimate what "high-volume UGC" actually looks like
I think a lot of people don't realize what "high-volume" actually means. From what I've seen, it's pretty common for creators working with tech brands to be making 80–300 videos a month for the same brand. Usually, it's all for one account (or a couple of accounts) where they're just testing stuff.
It's not really about trying to make every video perfect. You throw a bunch of ideas out there, see what people respond to, then make more versions of the ones that work: different hooks, different intros, different angles.
The volume kind of comes naturally once you're working like that. I also think that's why view-based pay makes sense. If the videos keep getting views, the brand wants more, and the creator keeps making more.
