Premiere Playback offset does nothing

PostThu Jan 16, 2020 8:21 pm

We have had this issue over multiple systems, Blackmagic devices and multiple monitors.

Currently we're on new Mac Pros with Decklink 4K Extreme 12Gs installed running Premiere 2020. Previously we were on the 2013 Mac Pros with UltraStudio 4Ks.

There is a 3-4 frame delay between the Premiere program monitor and the external monitor that we have connected through the Blackmagic devices. Audio is synced with the program monitor in Premiere which then means it's out of sync on the external client monitor.

So, naturally we head to the Playback preferences in Premiere and offset. When I connect an HDMI cable straight into the Mac to the same monitor that the Blackmagic is connected to, I offset Adobe Monitor 2 120ms and it's perfectly in sync. If I try to offset the Blackmagic device, even 500ms, it does nothing. No matter what I do, I can't get the timing of the Blackmagic device to change. Based on searching, this seems to have been a bug for years.

Do I have any options to get the Blackmagic output in sync?
