Thanks for being part of the BlendBuddy Beta Program! I'm working on providing documentation to help with the setup of BlendBuddy with other video sources.
This tutorial applies to BlackMagic input devices, using BlackSyphon for access to the input video stream via Syphon.
Basic setup goes as follows:
1. Setup BlackMagic Desktop Video (Currently Tested using 10.2.3) and verify settings(SDI or HDMI input etc).
2. Open BlackSyphon select the input device and resolution, if you see the source in the preview monitor continue, otherwise verify step 1 and source resolutions.
3. Open BlendBuddy-2.0b and you should see the stream from BlackSyphon.
