Ultrastudio 4k and HDMI sync
Posted: Fri Jan 22, 2016 4:52 pm
We are using the Blackmagic Ultrastudio 4k in our edit suite. We are encountering latency. It looks like video lags behind audio.
We have an iMac using Premiere Pro. We send our video and audio via thunderbolot to the Ultrastudio 4k. From the ultrastudio 4k, we send video to a FSI reference monitor via HD SDI and send video to the room’s big-screen TV via HDMI. Audio runs from the Ultrastudio via the analogue outs to a mixer that feeds the room speakers.
Is there a better way to route things that establishes audio and video sync?
Perhaps using the loop-through audio from the FSI monitor? The Flanders Scientific BM210 is sent video with audio on the SDI Out of the Ultrastudio. That FSI monitor has an audio out port (stereo mini). Maybe we loop out of the FSI monitor and feed that to the room speakers?
