When recording the vMix output through my laptop HDMI output (to Hyperdeck Shuttle), the audio is getting head of the video by almost a full 2 seconds after only 3-4 minutes of recording time. The longer I record, the worse it gets. The video is being captured thru a Magewell HDMI>USB capture device.
What could I change or check to stop this sync degradation from occuring? Tomorrow morning I will do a test stream to see if the same is happening on the stream or if it is only affects the recorded file on the H.Shuttle.
Any insight will be appreciated :)

This is a Hyperdeck Shuttle issue. This only occurs when using the HDMI input on the H.shuttle. The solution right now is to use a HDMI>SDI converter and input the video into the H.shuttle via SDI. I had no syncing issues after using the converter. Hopefully Blackmagic will fix it with a new firmware release.
