@mark_m ah ok...thanks for the warningBest,

Thank you. Issue solved. Combo output resolution and camera resetting itself. Thank you for the feedback.

 Currently only using one Ultrastudio MiniMonitor, running the firmware that comes with Desktop Video 11.3, last update 18. July 2019. I wouldn't call the Ultrastudio product line converters because they're proper video interfaces, like the Decklink PCIe cards. And because Blackmagic also builds actual converters (HDMI-to-SDI etc).I'm pretty much convinced the main problem I'm seeing (Prores files not playing back so reliably; see above) has nothing to do with the Ultrastudio output, given that GLSL shaders play back near-flawlessly.

@woland You could also look at the Blackmagic cleanswitch, it is a bit of a tricky beast as it will work better with reference (or reference SDI input 1). This would give you a clean switching matrix that could be more useful than a simple mixer. I am pretty sure it also uses UDP, if Izzy gets UDP (it's been knocking around on feature requests for a while) then you could control it within Izzy.

I recently acquired a Blackmagic Design Web Presenter for a live streaming project. It works perfectly as an input device for Isadora. It has two switchable video inputs, HDMI and SDI, with passthroughs for both, and an SDI PGM monitor out as well. Also RCA and XLR audio inputs.It only outputs 720p, but gives a good, steady signal into Isadora via USB2.It's rather more expensive than the other Blacmagic Capture devices, but its switchable dual inputs might be useful in certain situations.Anyhow, it works, and I just wanted to share that with all you Isadorables.

@kurtmeadows in general I would avoid using this method, unless you really need a feature from that pathway (like dual link 444 SDI). Also yes this is limited to a single output. The Blackmagic cards have no processing capability, it will waste a lot of resources to go back and forth from the GPU (where your image is calculated), back to the CPU and out the Blackmagic output.It seems your need is only monitoring what you output to the projectors, this can be done inside Isadora, or by splitting the output signals, or using a multiview monitor. I would go for adding an extra monitor to you gfx card and asking yourself a split screen preview of everything you need to see. Just use normal HDMI to SDI for your output (even Blackmagic sell these do 50 bucks these days). This way is less cabling and less work for your computer as well as only requiring a single screen for preview monitoring.

Hi, for a future request, is it possible to route all the 6 stages to black Magic thunderbolt to HD-SDI boxes? I know this means going back to CPU actors but the fluidity of the video card/box is much better than a graphics card. Thanks
