Last night I was trying to record, using Vmix, my pastor's sermon. I encountered a problem I was not able to resolve and it is my hope that those more experienced with Vmix in this forum may shed some light on a solution.
Despite Render Time, GPU. CPU numbers all being in the low single digits, the video in the live view window was lagging significantly. Here is a link to a short 17 sec. test clip to show what it looked like:
https://youtu.be/o2_uZ_F1pfQI have uploaded some screenshots of the configurations in use, as well as the configuration of the equipment I am using.
The strangest thing is, when I test this at home, there was zero lag; so I am completely perplexed. I am scheduled to retry another recording this evening, assuming I am able to find and correct the problem; to that end, I really could use some assistance.
