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.
Estoy practicando para ser competente en español. Si publicas en el foro en español, trataré de responder en la misma manera.
In reviewing the code for the Blackmagic nodes, we found a piece that might cause video mixups like you demonstrated. This could happen when using 2 or more Receive Blackmagic Video nodes. We'll have a possible fix for you to try in the Vuo 2.0 beta.
Thanks for reporting this problem and taking the time to test various configurations.
