Plug & play with Blackmagic video I/O devices is not supported (a relaunch of the application may be required to detect a re-connected device successfully)
Removing devices while the application is running may lead to performance issues; therefore, hot-plugging devices is currently not recommended
Using a macOS Multi-Output Device as the audio output device may lead to a hang on some systems. The hang originates in Apple’s audio engine while the Multi-Output Device is being configured and occurs sporadically; using a macOS Multi-Output Device with Reeltime is currently not recommended. As a workaround:
Select a single, dedicated audio output device in Reeltime’s Audio Settings instead of a macOS Multi-Output Device (see Setting up audio I/O interfaces)
To send audio to more than one destination, route it outside of Reeltime, for example through a hardware audio split
