Can you enable "Low Level Debugging" in Voukoders Settings? This should log more data (and the actual error). Sorry, I know that's a 10 hrs encode ...
Yes, sure, I'll enable low level debugging and try to render again. Will update you once I get the log.
Are you sure there's enough drive space left?
I've got like 40 gigs left, but I think that's enough. After video render completion there's still a lot of space left. The 28 rendered minutes out of 45 was like 11 gigs.
