I'm seeing a crazy brightness flicker happening on renders to 4k mp4 when my project is set to 32-bit video levels. 8-bit renders are working fine. I just switched to new hardware, so can't rule out the possibility that it isn't a Vegas issue, but I haven't seen this problem before and everything else in my project is typical of my workflow.
Anyone seen anything like this? On the timeline (not while rendering), when I walk through frames with the arrow keys, *some* of the frames will suddenly darken. If I shuttle forward a bit, and then return to the dark frame, it appears normal. So it's not even consistent to frame numbers. Vegas...sigh.
