As one of Vuo's developers, I work on Vuo's engine (the thing that makes compositions run), work on nodes, and write documentation. You'll see me on the forums answering people's questions about Vuo.
I enjoy using Vuo to make live music visuals. My hope for Vuo is that it will grow into a community of people of diverse backgrounds and identities making lots of different artistic, useful, unique, goofy, beautiful, crafty, wonderful compositions.

Well, we looked into this and the resolution seems to depend entirely on YouTube, not something we can configure on our site. We can control the size of the video widget on the page, but not the resolution of the video that actually plays. We tried this solution but it no longer works. YouTube chooses the video resolution based on the user's YouTube settings and YouTube's determination of the user's available bandwidth.
