I am the Senior AV Broadcast Technology Analyst at Loyalist College where I primarily design, install and maintain campus AV, Digital Signage and Broadcast systems and equipment. I have also do some teaching for Camera, VFX and Audio/Video editing as well; I love my job. My background includes Broadcast Television, Video Production and Technical work. My passions include traditional and digital drawing, fictional creative writing, VFX, and cinematic video projects. I have also recently rekindled my interest in robotics and have tinkered with Arduino and Raspberry Pi and a few programable robots.
I find I most comfortably find myself in the chaotic limbo between the artistically and technically creative, believing one can indeed excel at both. Which is probably why I am loving VUO! :)
On an extremely complex composition that I can't unfortunatly post I couldn't get 2 Receive Blackmagic Video nodes using 2 Blackmagic UltraStudio Mini Recorders to work in the same composition properly. Watch link below to see an example of the issue. Each BM UltraStudio Mini Recorder has it's own address and can be used in OBS together and usually worked in a much simpler Vuo composition but has issues in the complex composition. What's even stranger is that swapping the BM node out of the receive live video node fixes the issue with nothing else changed so this has to be an issue with the BM node itself I think. Right?
I have tried to create a simpler composition showing the issue but only ran across the issue one other time. However after a reload of that project it started working properly and I wasn't able to recreate the issue on that project again.
Have you found a workaround?:
Make sure you are using MacOS 10.14.3 or earlier. With nothing else changed I replaced one of the Receive Blackmagic Video nodes for a Receive Live Video node and this resolved the issue.
OSX 10.14.3? That requires a complete reinstall of OSX right?
I might have a work around for my project using a 2nd Blackmagic UltraStudio Mini Recorder so I don't have to use the Receive Video Node but at the moment I'm having a weird conflicting issue were frames from the one Blackmagic device enter and disrupt the image of the other (along with some green flashes and lines). I didn't get this when the other camera was a webcam on the Receive Live Video node. Still testing because when I make a simple composition with both Blackmagic capture devices I haven't seen the issue yet. Both cameras are running at the same frame rate in this test so it's not the exact issue I reported before I don't think.
