I think it varies based on your traffic.
I am currently using Admob and get $3-$5 per 1,000 video views. I am also using moblyft.com to help me maximize my revenue. I inserted moblyft video ads as a custom network in admob. MobLyft has been generating $8 - $12 per 1,000 views for me.
I am currently earning $14,500k a month.
