I have the same buffering issue occur on two different production computers. Both happen about 50 to 60 minutes into the LIVE STREAM. I even bought a new LAPTOP per the Spec from Martin and Tim from B & H (ASUS) and created new templates and limited my inputs and it still happens. Just now this was for a YouTube Live Stream and this is just a snippit of the same error I get. It went on for over an hour, clearing up for a short time period. I even reduced the stream for 1080p 60fps to 1080 to 720. I reduced the bps to from 6000 to 4500 to no avail. Still happens. What is the vMix Video YV12 buffer??? My internet is 1GB, (939 down and 41 to 45 up)

Can someone help or point me in the right Direction?
