To be sure I understand this correcty.
You say that when setting the latency to 0 ms, you can hear the input of your microphone (Direct Monitoring) without any delay.
When dialing the 280ms delay into the Blackmagic Card’s video settings, the input of the micorphone get’s delayed by 280ms.
Is that correct?
BTW, Jay is talking about recording a voice at distance (different locations over the internet) through VST connect. Has nothing to do with real time recording as you describe it.
