Currently Vuo can capture live video from some (or all?) BlackMagic devices using QuickTime. Adding direct support via the BlackMagic API may help reduce latency.

Does anybody know if QT Video

Does anybody know if QT Video method @Steve referred to brings the miniRecorder signal in? I have one and am about to buy a second device, prob another miniRecorder.

Apart from latency how would a native node help? Settings and config? I have votes ready to release on this if it's a significant improvement or needed.

The BlackSyphon read-me suggests that CPU use is reduced with hard coding thereby avoiding QT method. This feature would provide more functionality for compiled apps too i guess.

By the way, I don't remember

I've had reasonable success with the Blackmagic UltraStudio Mini Recorder using the native "Receive Live Video" node. In testing it had 5frame of latency for a 29.97fps clip (so 167ish ms of latency), that was at 1080p over HDMI, not sure if SDI would be faster.

A native Blackmagic node might be nice if it could reduce it to 1-2frames.

Yay implementation!

I now have two Ultrastudio Minirecorders @Jaymie and one issue with them in mimoLive is that they don't have any MAC address or UUID far as I/Bonix know. So when you reopen a mimoLive file the Source assignments to each Minirecorder are essentially random. It's not ideal, as you have to go into the Sources tab in mimoLive and reassign them if they loaded in the wrong order.

It could be worth mentioning this fact to BlackMagic Design if you correspond with them. i.e. adding something in the Ultrastudio/Minirecorder Firmware to make them have a unique ID that Vuo can identify in the node and so find again if something drops out or the composition is restarted. Prob BMD will take more notice if it comes from Kosada than me!

Also Bonix say two is the limit of MiniRecorders you can use on one Mac, be interesting to get confirmation that this true (or just a mimoLive thing).
