I wanted to lift up a project done in collaboration with my friend David Paskin, which uses Isadora and ZoomOSC to create chat overlay graphics that you can bring into your streaming workflow. The process outlined here, shown with Ecamm Live as an example, could be used with OBS, vMix, Wirecast, etc. via the NDI outputs from Isadora, or if you use hardware workflows like the ATEM, you could use the hardware output options from Isadora to do this as well. In fact, with the built-in Isadora RTMP streamer, or syphon virtual camera, you could do all of this streaming / sharing entirely within Isadora. It's really up to you!
Check out the video:
Under the hood, the Isadora file uses the new bounding box info from the Text Draw Actor. Using that data I can slide the question away from the name, pinch in the question from the bounds of the background rectangle, vertically adjust the question to center to the name, scale the rectangle to fit the question text inside, and move the entire graphic to minimize the screen space, all on the fly, based only on the input text.
