Well, I thought I fixed it but the default setup was in a different aspect ration. Youtube is 1280×720 and the default setup is 1440×1080. When I render in 1440×1080 the video is a bit stretched on youtube. But when I render in 1080×720 I get the black screen and error message…

I’m back to square 1 again.

Well after about 4 hours of rendering fails and testing it seems that I had to change my “set up” render settings to the default one.
